The Above For Gasoline Engines

FOR ENGINE
powered equipment.

1.a. Turn the engine off before troubleshooting and maintenance
work unless the maintenance work requires it to be running.

____________________________________________________

1.b. Operate engines in open, well-ventilated
areas or vent the engine exhaust fumes
outdoors.

____________________________________________________

1.c. Do not add the fuel near an open flame
welding arc or when the engine is running.
Stop the engine and allow it to cool before
refueling to prevent spilled fuel from vaporiz­ing on contact with hot engine parts and
igniting. Do not spill fuel when filling tank. If
fuel is spilled, wipe it up and do not start
engine until fumes have been eliminated.

____________________________________________________

1.d. Keep all equipment safety guards, covers and devices in
position and in good repair.Keep hands, hair, clothing and
tools away from V-belts, gears, fans and all other moving
parts when starting, operating or repairing equipment.

____________________________________________________

1.e. In some cases it may be necessary to remove safety

guards to perform required maintenance. Remove
guards only when necessary and replace them when the
maintenance requiring their removal is complete.
Always use the greatest care when working near moving
parts.

___________________________________________________

1.f. Do not put your hands near the engine fan.
Do not attempt to override the governor or
idler by pushing on the throttle control rods
while the engine is running.

1.h. To avoid scalding, do not remove the
radiator pressure cap when the engine is
hot.

ELECTRIC AND
MAGNETIC FIELDS
may be dangerous

2.a. Electric current flowing through any conductor causes
localized Electric and Magnetic Fields (EMF). Welding
current creates EMF fields around welding cables and
welding machines

2.b. EMF fields may interfere with some pacemakers, and
welders having a pacemaker should consult their physician
before welding.

2.c. Exposure to EMF fields in welding may have other health
effects which are now not known.

2.d. All welders should use the following procedures in order to
minimize exposure to EMF fields from the welding circuit:

2.d.1.

Route the electrode and work cables together - Secure
them with tape when possible.

2.d.2. Never coil the electrode lead around your body.

2.d.3. Do not place your body between the electrode and

work cables. If the electrode cable is on your right
side, the work cable should also be on your right side.

___________________________________________________

1.g. To prevent accidentally starting gasoline engines while
turning the engine or welding generator during maintenance
work, disconnect the spark plug wires, distributor cap or
magneto wire as appropriate.

2.d.4. Connect the work cable to the workpiece as close as
possible to the area being welded.

2.d.5. Do not work next to welding power source.

ELECTRIC SHOCK can
kill.

3.a. The electrode and work (or ground) circuits
are electrically “hot” when the welder is on.
Do not touch these “hot” parts with your bare
skin or wet clothing. Wear dry, hole-free

gloves to insulate hands.

3.b. Insulate yourself from work and ground using dry insulation.
Make certain the insulation is large enough to cover your full
area of physical contact with work and ground.

In addition to the normal safety precautions, if welding
must be performed under electrically hazardous
conditions (in damp locations or while wearing wet
clothing; on metal structures such as floors, gratings or
scaffolds; when in cramped positions such as sitting,
kneeling or lying, if there is a high risk of unavoidable or
accidental contact with the workpiece or ground) use
the following equipment:

• Semiautomatic DC Constant Voltage (Wire) Welder.

• DC Manual (Stick) Welder.

• AC Welder with Reduced Voltage Control.

3.c. In semiautomatic or automatic wire welding, the electrode,
electrode reel, welding head, nozzle or semiautomatic
welding gun are also electrically “hot”.

3.d. Always be sure the work cable makes a good electrical
connection with the metal being welded. The connection
should be as close as possible to the area being welded.

3.e. Ground the work or metal to be welded to a good electrical
(earth) ground.

ARC RAYS can burn.

4.a. Use a shield with the proper filter and cover
plates to protect your eyes from sparks and
the rays of the arc when welding or observing
open arc welding. Headshield and filter lens
should conform to ANSI Z87. I standards.

4.b. Use suitable clothing made from durable flame-resistant
material to protect your skin and that of your helpers from
the arc rays.

4.c. Protect other nearby personnel with suitable, non-flammable
screening and/or warn them not to watch the arc nor expose
themselves to the arc rays or to hot spatter or metal.

FUMES AND GASES
can be dangerous.

5.a. Welding may produce fumes and gases
hazardous to health. Avoid breathing these
fumes and gases.When welding, keep
your head out of the fume. Use enough
ventilation and/or exhaust at the arc to keep

fumes and gases away from the breathing zone. When

welding with electrodes which require special
ventilation such as stainless or hard facing (see
instructions on container or MSDS) or on lead or
cadmium plated steel and other metals or coatings
which produce highly toxic fumes, keep exposure as
low as possible and below Threshold Limit Values (TLV)
using local exhaust or mechanical ventilation. In
confined spaces or in some circumstances, outdoors, a
respirator may be required. Additional precautions are
also required when welding on galvanized steel.

3.f.

Maintain the electrode holder, work clamp, welding cable and
welding machine in good, safe operating condition. Replace
damaged insulation.

3.g. Never dip the electrode in water for cooling.

3.h. Never simultaneously touch electrically “hot” parts of
electrode holders connected to two welders because voltage
between the two can be the total of the open circuit voltage
of both welders.

3.i. When working above floor level, use a safety belt to protect
yourself from a fall should you get a shock.

3.j. Also see Items 6.c. and 8.

5.b.

Do not weld in locations near chlorinated hydrocarbon

coming from degreasing, cleaning or spraying operations.
The heat and rays of the arc can react with solvent vapors
form phosgene, a highly toxic gas, and other irritating
products.

5.c. Shielding gases used for arc welding can displace air and

cause injury or death. Always use enough ventilation,
especially in confined areas, to insure breathing air is safe.

5.d. Read and understand the manufacturer’s instructions for this

equipment and the consumables to be used, including the

material safety data sheet (MSDS) and follow your

employer’s safety practices. MSDS forms are available from

your welding distributor or from the manufacturer.

WELDING SPARKS can
cause fire or explosion.

6.a.

Remove fire hazards from the welding area.

If this is not possible, cover them to prevent

the welding sparks from starting a fire.

materials from welding can easily go through small cracks
and openings to adjacent areas. Avoid welding near
hydraulic lines. Have a fire extinguisher readily available.

6.b. Where compressed gases are to be used at the job site,
special precautions should be used to prevent hazardous
situations. Refer to “Safety in Welding and Cutting” (ANSI
Standard Z49.1) and the operating information for the
equipment being used.

6.c. When not welding, make certain no part of the electrode
circuit is touching the work or ground. Accidental contact
can cause overheating and create a fire hazard.

6.d. Do not heat, cut or weld tanks, drums or containers until the
proper steps have been taken to insure that such procedures
will not cause flammable or toxic vapors from substances
inside. They can cause an explosion even
been “cleaned”. For information, purchase “Recommended
Safe Practices for the
Containers and Piping That Have Held Hazardous
Substances”, AWS F4.1 from the American Welding Society

(see address above).

6.e. Vent hollow castings or containers before heating, cutting or
welding. They may explode.

Sparks and spatter are thrown from the welding arc. Wear oil

6.f.
free protective garments such as leather gloves, heavy shirt,
cuffless trousers, high shoes and a cap over your hair. Wear
ear plugs when welding out of position or in confined places.
Always wear safety glasses with side shields when in a
welding area.

6.g. Connect the work cable to the work as close to the welding
area as practical. Work cables connected to the building
framework or other locations away from the welding area
increase the possibility of the welding current passing
through lifting chains, crane cables or other alternate cir­cuits. This can create fire hazards or overheat lifting chains
or cables until they fail.

6.h. Also see item 1.c.

Remember that welding sparks and hot

though

CYLINDER may explode
if damaged.

7.a. Use only compressed gas cylinders
containing the correct shielding gas for the
process used and properly operating
regulators designed for the gas and

pressure used. All hoses, fittings, etc. should be suitable for
the application and maintained in good condition.

7.b. Always keep cylinders in an upright position securely
chained to an undercarriage or fixed support.

7.c. Cylinders should be located:

• Away from areas where they may be struck or subjected to

physical damage.

• A safe distance from arc welding or cutting operations and

any other source of heat, sparks, or flame.

7.d. Never allow the electrode, electrode holder or any other
electrically “hot” parts to touch a cylinder.

7.e. Keep your head and face away from the cylinder valve outlet
when opening the cylinder valve.

7.f. Valve protection caps should always be in place and hand
tight except when the cylinder is in use or connected for
use.

7.g. Read and follow the instructions on compressed gas
cylinders, associated equipment, and CGA publication P-l,

PRÉCAUTIONS DE SÛRETÉ

Pour votre propre protection lire et observer toutes les instruc­tions et les précautions de sûreté specifiques qui parraissent
dans ce manuel aussi bien que les précautions de sûreté
générales suivantes:

Sûreté Pour Soudage A L’Arc

1. Protegez-vous contre la secousse électrique:

a. Les circuits à l’électrode et à la piéce sont sous tension

quand la machine à souder est en marche. Eviter toujours
tout contact entre les parties sous tension et la peau nue
ou les vétements mouillés. Porter des gants secs et sans
trous pour isoler les mains.

b. Faire trés attention de bien s’isoler de la masse quand on

soude dans des endroits humides, ou sur un plancher
metallique ou des grilles metalliques, principalement dans

les positions assis ou couché pour lesquelles une
grande partie du corps peut être en contact avec la
masse.

c. Maintenir le porte-électrode, la pince de masse, le câble

de soudage et la machine à souder en bon et sûr état
defonctionnement.

d.Ne jamais plonger le porte-électrode dans l’eau pour le

refroidir.

e. Ne jamais toucher simultanément les parties sous tension

des porte-électrodes connectés à deux machines à soud­er parce que la tension entre les deux pinces peut être le
total de la tension à vide des deux machines.

f. Si on utilise la machine à souder comme une source de

courant pour soudage semi-automatique, ces precautions
pour le porte-électrode s’applicuent aussi au pistolet de
soudage.

5. Toujours porter des lunettes de sécurité dans la zone de
soudage. Utiliser des lunettes avec écrans lateraux dans les
zones où l’on pique le laitier.

6. Eloigner les matériaux inflammables ou les recouvrir afin de
prévenir tout risque d’incendie dû aux étincelles.

7. Quand on ne soude pas, poser la pince à une endroit isolé de
la masse. Un court-circuit accidental peut provoquer un
échauffement et un risque d’incendie.

8. S’assurer que la masse est connectée le plus prés possible
de la zone de travail qu’il est pratique de le faire. Si on place
la masse sur la charpente de la construction ou d’autres
endroits éloignés de la zone de travail, on augmente le risque
de voir passer le courant de soudage par les chaines de lev­age, câbles de grue, ou autres circuits. Cela peut provoquer
des risques d’incendie ou d’echauffement des chaines et des
câbles jusqu’à ce qu’ils se rompent.

9. Assurer une ventilation suffisante dans la zone de soudage.
Ceci est particuliérement important pour le soudage de tôles
galvanisées plombées, ou cadmiées ou tout autre métal qui
produit des fumeés toxiques.

10. Ne pas souder en présence de vapeurs de chlore provenant
d’opérations de dégraissage, nettoyage ou pistolage. La
chaleur ou les rayons de l’arc peuvent réagir avec les
vapeurs du solvant pour produire du phosgéne (gas forte­ment toxique) ou autres produits irritants.

11. Pour obtenir de plus amples renseignements sur la sûreté,
voir le code “Code for safety in welding and cutting” CSA
Standard W 117.2-1974.

2. Dans le cas de travail au dessus du niveau du sol, se pro­téger contre les chutes dans le cas ou on recoit un choc. Ne
jamais enrouler le câble-électrode autour de n’importe quelle
partie du corps.

3. Un coup d’arc peut être plus sévère qu’un coup de soliel,
donc:

a. Utiliser un bon masque avec un verre filtrant approprié

ainsi qu’un verre blanc afin de se protéger les yeux du
rayonnement de l’arc et des projections quand on soude
ou quand on regarde l’arc.

b. Porter des vêtements convenables afin de protéger la

peau de soudeur et des aides contre le rayonnement de
l‘arc.

c. Protéger l’autre personnel travaillant à proximité au

soudage à l’aide d’écrans appropriés et non-inflamma­bles.

4. Des gouttes de laitier en fusion sont émises de l’arc de
soudage. Se protéger avec des vêtements de protection
libres de l’huile, tels que les gants en cuir, chemise épaisse,
pantalons sans revers, et chaussures montantes.

PRÉCAUTIONS DE SÛRETÉ POUR
LES MACHINES À SOUDER À
TRANSFORMATEUR ET À
REDRESSEUR

1. Relier à la terre le chassis du poste conformement au code
de l’électricité et aux recommendations du fabricant. Le dis­positif de montage ou la piece à souder doit être branché à
une bonne mise à la terre.

2. Autant que possible, I’installation et l’entretien du poste
seront effectués par un électricien qualifié.

3. Avant de faires des travaux à l’interieur de poste, la
debrancher à l’interrupteur à la boite de fusibles.

4. Garder tous les couvercles et dispositifs de sûreté à leur
place.

when connect-

CAUTION

• Loose connections will cause the output terminals

to overheat. The terminals may eventually melt.

• Do not cross the welding cables at the output termi-

nal connection. Keep the cables isolated and sepa­rate from one another.

WARNING

Do not ground the machine to a pipe that carries
explosive or combustible material.

When the POWER ARC 5000 is mounted on a truck
or a trailer, the machine generator grounding terminal
MUST be securely connected to the metal frame of
the vehicle. See Figure A.3. The grounding terminal
is marked with the symbol.

AUXILIARY POWER RECEPTACLES

The control panel of the POWER ARC 5000 features
three auxiliary power receptacles:

• One 15 amp, 120 volt ground fault circuit inter­rupter (GFCI) duplex interrupter (NENA Style 5­15R).

• One 30 amp 120 volt Twist-Lock receptacle (NEMA
Style L5-30R).

• One 30 amp 120/240 volt Twist-Lock receptacle
(NEMA Style L14-30R).

Lincoln Electric offers a welding accessory kit with
the properly specified welding cables. See the

POWER CORD CONNECTIONS TO TWIST­LOCK PLUGS

Refer to the appropriate diagram above for proper
connection of power cord wires to the Twist-Lock plug
terminals. Also, read the instruction sheet supplied
with the Twist-lock plug.

PLUGS AND HAND-HELD EQUIPMENT

For further protection against electric shock, any 120
volt hand-held equipment connected to the generator
receptacles must use a three-blade, grounded type
plug or an Underwriter’s Laboratories (UL) approved
double insulation system with a two-blade plug.

CIRCUIT BREAKERS

The POWER ARC 5000 has circuit
breakers for overload protection.
When the machine is operated in high
temperature environments, the
breakers may tend to trip at lower loads than normal­ly.

CAUTION

Never bypass the circuit breakers. Without overload
protection, the POWER ARC 5000 could overheat
and/or cause damage to the equipment being used.

PREMISES WIRING

The POWER ARC 5000 three-wire, grounded neutral
generator allows it to be connected to premises
wiring. However, the wiring procedure needed to

meet the National Electric Code (NEC) regulations as
well as city ordinances can be confusing. Matters get
worse depending on whether you want the machine
to be “hardwired” to the premises or only connected
temporarily.

WARNING

Only a licensed, certified, trained electrician should
install the machine to a premises or residential electri­cal system. Be certain that:

• The premises is isolated and no feedbacking into
the utility system can occur. Certain state and
local laws require the premises to be isolated
before the generator is linked to the premises.
Check your state and local requirements.

• A double pole, double throw transfer switch in con­junction with the properly rated double throw cir­cuit breaker is connected between the generator
power and the utility meter.

Remember that the POWER ARC 5000 is intended
only for backup, intermittent use. It cannot withstand
long-term use without proper maintenance. See the
MAINTENANCE section of this manual for more

RECOMMENDED APPLICATIONS

OPERATIONAL FEATURES AND CONTROLS

The POWER ARC 5000 was designed for simplicity.
Therefore, it has very few operating controls. A single
dial on the control panel lets you select either genera­tor or welding use. For welding, the same dial selects
continuous current output over the machine’s 70 to
125 amp low range and 90 to 150 amp high range.

The 11 HP Briggs & Stratton gasoline engine controls
include a recoil starter, choke, stop switch and low idle
control. See ENGINE OPERATION Section for
details about starting, running, stopping and breaking
in the gasoline engine.

GENERATOR

The POWER ARC 5000 gives AC generator output for
medium use, commercial demands. For more details
on operating the generator, see GENERATOR OPER­ATION in this section of the manual.

WELDER

The POWER ARC 5000 provides excellent constant
current AC welding output for stick (SMAW) welding.
For more details on using the machine as a welder,
see WELDING OPERATION in this section of the
manual.

WELDING CAPABILITY

The POWER ARC 5000 is rated 150 amps, 25 volts at
40% duty cycle on a ten-minute basis. This means
that you can load the welder to 150 amps for four
minutes out of every ten-minute period. The machine
is also capable of higher duty cycles at lower output
currents. You can load the welder to 125 amps for six
minutes out of ten for a 60% duty cycle.

The current is continuously variable from 70 to 125
amps and 90 to 150 amps depending on which out­put range is selected. The POWER ARC 5000 can
weld with all 3/32”, most 1/8”, and some 5/32” diam­eter Lincoln AC electrodes.

LIMITATIONS

• The POWER ARC 5000 is not recommended for

any processes besides those that are normally per­formed using stick welding (SMAW) procedures.

• The POWER ARC 5000 is not recommended for

pipe thawing.

• The POWER ARC 5000 is not

AC TIG welding.

• During welding, generator power is limited to 100

watts, and output voltages can drop from 120 to 80
volts and 240 to 160 volts. Therefore, DO NOT
OPERATE ANY SENSITIVE ELECTRICAL EQUIP­MENT WHILE YOU ARE WELDING.

WARNING

DO NOT RUN THE ENGINE AT EXCESSIVE SPEEDS.
The maximum allowable high idle speed for the
POWER ARC 5000 is 3750 RPM, no load. Do NOT
adjust the governor screw on the engine. Severe per­sonal injury and damage to the machine can result if
it is operated at speeds above the maximum rated
speed.

Read and understand all safety instructions included
in the Briggs & Stratton Operating and Maintenance
Instructions manual that is shipped with the POWER
ARC 5000.

BEFORE STARTING THE ENGINE

CHECK AND FILL THE ENGINE OIL
LEVEL:

1. Place the machine on a level surface.

2. Remove the oil fill cap and dip-stick.

3. Fill (if necessary)to the full mark on the dip-stick.
Do NOT overfill.

4. Replace the oil fill cap and tighten securely.

CHECK AND FILL THE ENGINE FUEL TANK:

1. Remove the fuel tank cap.

2. Fill the tank to allow approximately 1.5
inches (38 mm) from top of filler neck
to allow for fuel expansion. DO NOT
FILL THE TANK TO THE POINT OF
OVERFLOW.

3. Replace the fuel tank cap and tighten securely.

NOTE: The engine will operate satisfactorily on any

gasoline meant for automotive use. A mini­mum of 87 octane is recommended. DO NOT
MIX OIL WITH THE GASOLINE.

Use clean, fresh, lead-free gasoline. Leaded gasoline
may be used if lead-free is not available. However,
lead-free gasoline leaves fewer combustion deposits
and gives longer valve life. For engine protection
from fuel deposits, use Briggs & Stratton Gasoline
Additive, part number 5041. Purchase gasoline in
quantities that will be used within 30 days, to assure
freshness.

NOTE: We DO NOT recommend using gasoline that

contains alcohol, such as gasohol. However,
if gasoline with alcohol is used, it MUST NOT
contain more than 10% Ethanol and MUST
be removed from the engine during storage.
DO NOT use gasoline containing Methanol.

STARTING THE ENGINE

NOTE: Remove all loads connected to the AC power

receptacles before starting the gasoline
engine. Push the On-Off Stop Switch to the
“ON” position.

FOR A “COLD” ENGINE:

1. Open the fuel shutoff valve on the bottom of the
fuel tank by turning it full counterclockwise.

2. Place the choke lever in the lowest,
downward position.

3. Pull slightly on the recoil starter handle
until resistance is felt.

B-6

4. Pull the cord rapidly.

5. If the engine does not start, open the choke
slightly (move lever toward the “RUN” position)
and pull the starter cord rapidly again. When the
engine starts, gradually open the choke to the
“RUN” position.

FOR A “HOT” ENGINE:

1. Open the fuel shutoff valve on the bottom of the
fuel tank by turning it full counterclockwise.

2. Place the choke lever in the “RUN”
position. Closing the choke of a hot
engine will flood the carburetor and
prevent starting.

3. Pull slightly on the recoil starter handle until resis­tance is felt.

4. Pull the cord rapidly.

FOR BEST ENGINE STARTING:

• Always use fresh gasoline and be sure the filter is

clean and properly maintained.

• If you use an alternate fuel tank or supply, be sure

to install an in-line fuel filter.

• Do not pull the recoil starter with the

choke in the choke position more than
one time. Repeated pulls on a choked
engine will flood the carburetor.

OPERATION

B-6

WARNING

Close the fuel valve when the machine is transported
to prevent fuel leakage from the carburetor.

BREAK-IN PERIOD

The engine will use a greater amount of oil during its
“break-in” period. The break-in is about 12 running
hours.

Check the oil frequently during break-in. Change the
oil after the first 5 hours of operation. For more
details, see the MAINTENANCE section of this manu­al.

CAUTION

During break-in, subject the POWER ARC 5000 to
only moderate loads. Avoid long periods running at
idle. Before stopping the engine, remove all loads

GENERATOR OPERATION

CAUTION

Be sure that any electrical equipment plugged into
the generator’s AC power receptacles can withstand
a +5%-15% voltage and a ±5% frequency variation.
Some electronic devices cannot be powered by the
POWER ARC 5000. Refer to Table A.2, ELECTRICAL
DEVICE USE WITH THE POWER ARC 5000, in the

GENERAL INFORMATION

The POWER ARC 5000 generator is rated at 5000
continuous watts. It provides both 120 volt and 240
volt power. You can draw up to 15 amps from either
side of the 120 volt duplex receptacle. Up to 30amps
can be drawn from the 120 volt Twist-Lock recepta­cle. Up to 20.8 amps of 240 volt power can be drawn
from the 120/240 volt Twist-Lock receptacle.

Electrical loads in watts are calculated by multiplying
the voltage rating of the load by the number of amps
it draws. (This information is given on the load device
nameplate.) For example, a device rated 120 volts, 2
amps will need 240 watts of power (120 x 2 = 240).

You can use Table B.3, GENERATOR POWER APPLI­CATIONS, to determine the wattage requirements of
the most common types of loads you can power with
the POWER ARC 5000. Be sure to read the notes at
the bottom of the table.

TO USE THE GENERATOR AS AN AUXILIARY
POWER SUPPLY:

1. Start the gasoline engine. See ENGINE OPERA­TION in this section of the manual.

2. Set the current control dial on the output control
panel to “GENERATOR.” See Figure B.1.

3. Plug the load(s) into the appropriate 120 volt or
240 volt power receptacle.

NOTE: During welding, the maximum generator out-

put for auxiliary loads is 100 watts.

NOTE: You can supply multiple loads as long as the

total load does not exceed 4,000 watts. Be
sure to start the largest loads first.

The POWER ARC 5000 generator/welder can deliver
from 70 to 150 amps of welding current for stick
welding. Output can be adjusted by setting the cur­rent control dial on the output control panel.

The numbers on the dial correspond to the average
amps needed to weld using specific Lincoln welding
rods. Table B.4, WELDING APPLICATIONS, gives
you the recommended dial settings based on the
thickness of the work and the size and type of rod
you are using.

TO USE THE POWER ARC 5000 FOR STICK WELDING:

1. The engine must be OFF when connecting the
welding cables. Remove the flange nuts from the
weld output terminals and place the work and
electrode welding cables over the terminals. See
Figure B.1. Replace and tighten the flange nuts
securely. Be sure the connections are tight.

3. Attach the work clamp securely to the work you
are welding.

4. Insert the electrode into the electrode holder.

5. Set the current control dial to the desired output
current.

6. Start the gasoline engine. See ENGINE OPERA-
TION in this section of the manual.

7. Strike an arc and begin welding. For information
on welding techniques, see WELDING GUIDE-
LINES in this section of the manual.

AFTER YOU FINISH THE WELD:

1. Stop the gasoline engine. See ENGINE OPERA­TION in this section of the manual.

2. Allow the electrode and work to cool completely.

3. Remove the work clamp from the work.

4. Remove any remaining piece of electrode from
the electrode holder.

5. If you are finished using the POWER ARC 5000
for welding, disconnect the welding cables from
the weld output terminals. Reattach the flange
nuts and leave them on the terminals.

NOTE: 1. Welding current is continuously variable

with 60% duty cycle applying to output
currents 125 Amps and less and 40%
duty cycle applying to currents above 125
Amps.

it is necessary to use correct eye,
head and body protection.

The Power-Arc provides excellent weld output charac­teristics when used in combination with Lincoln AC

Learning To Stick Weld

The serviceability of a product or structure utilizing this
type of information is and must be the sole responsi­bility of the builder/user. Many variables beyond the
control of The Lincoln Electric Company affect the
results obtained in applying this type of information.
These variables include, but are not limited to, welding
procedure, plate chemistry and temperature, weld­ment design, fabrication methods and service require­ments.

No one can learn to weld simply by reading about it.
Skill comes only with practice. The following pages
will help the inexperienced welder understand welding
and develop his skill. For more detailed information,
order a copy of the book “New Lessons in Arc
Welding.”

The operator’s knowledge of arc welding must go
beyond the arc itself. He must know how to control the
arc, and this requires a knowledge of the welding cir­cuit and the equipment that provides the electric cur­rent used in the arc. Figure B.3 is a diagram of the
welding circuit. The circuit begins where the electrode
cable is attached to the welding machine and ends
where the work cable cable is attached to the
machine. Current flows through the electrode cable to
the electrode holder, through the electrode holder to
the electrode and across the arc. On the work side of
the arc, the current flows through base metal to the
work cable and back to the welding machine. The cir­cuit must be complete for the current to flow. To weld,
the work clamp must be tightly connected to clean
base metal. Remove paint, rust,etc. as necessary to
get a good connection. Connect the work clamp as
close as possible to the area you wish to weld. Avoid
allowing the welding circuit to pass through hinges,
bearings, electronic components or similar devices
that can be damaged.

The POWER ARC 5000 has a voltage output of up to
62 volts which can shock.

WARNING

ELECTRIC SHOCK can kill.

• Do not touch electrically live parts
or electrode with skin or wet cloth­ing.

• Insulate yourself from work and

ground.

• Always wear dry insulating gloves.

ENGINE EXHAUST can kill.

• Use in open, well ventilated areas
or vent exhaust outside.

• Do not stack anything on or near
the engine.

MOVING PARTS can injure.

• Do not operate with doors open or
guards off.

• Stop engine before servicing.

• Keep away from moving parts.

Only qualified personnel should install, use, or
service this equipment.

The electric arc is made between the work and the tip
end of a small metal wire, the electrode, which is
clamped in a holder that is held by the welder. A gap
is made in the welding circuit (see Figure B.3) by hold­ing the tip of the electrode 1/16 - 1/8” (1.6-3.2mm)
away from the work or base metal being welded. The
electric arc is established in this gap and is held and
moved along the joint to be welded, melting the metal
as it is moved.

Arc welding is a manual skill requiring a steady hand,
good physical condition, and good eyesight. The
operator controls the welding arc and, therefore, the
quality of the weld made.

cannot be looked at with the naked eye without risking
painful and possibly permanent injury. A very dark
lens, specifically designed for arc welding must be
used with the handshield or headshield whenever
viewing the arc.

The arc melts the base metal and actually digs into it,
much like water through a garden hose nozzle digs
into the earth. The molten metal forms a pool or
crater and tends to flow away from the arc. As it
moves away from the arc, it cools and solidifies. Slag
forms on top of the weld to protect it during cooling.

The function of the covered electrode is much more
than simply to carry current to the arc. The electrode
is composed of a core metal wire around which has
been extruded and baked a chemical covering. The
core wire melts into the arc and tiny droplets of molten
metal shoot across the arc into the molten pool. The
electrode provides additional filler metal for the joint to
fill the groove or gap between the two pieces of the
base metal. The covering also melts or burns in the
arc. It has several functions. It makes the arc stead­ier, provides a shield of smoke-like gas around the arc
to keep oxygen and nitrogen in the air away from the
molten metal, and provides a flux for the molten pool.
The flux picks up impurities and forms a protective
slag. The principle differences between the various
types of electrodes are in their coatings. By varying
the coating, it is possible to greatly alter the operating
characteristics of electrodes. By understanding the
differences in the various coatings, you will gain a bet­ter understanding of selecting the best electrode for
the job you have at hand. In selecting an electrode,
you should consider:

1. The type of deposit you want, e.g., mild steel,
stainless, low alloy, hardfacing.

What Happens in the Arc?

Figure B.4 illustrates the action that takes place in the
electric arc. It closely resembles what is actually seen
during welding.

The “arc stream” is seen in the middle of the picture.
This is the electric arc created by the electric current
flowing through the space between the end of the
electrode and the work. The temperature of this arc is
about 6000°F (3316°C) which is more than enough to
melt metal. The arc is very bright, as well as hot, and

2. The thickness of the plate you want to weld.

3. The position it must be welded in (downhand,
out-of-position).

4. The surface condition of the metal to be welded.

5. Your ability to handle and obtain the desired
electrode.

Four simple manipulations are of prime importance.
Without complete mastery of these four, further
attempts at welding are futile. With complete mastery
of the four, welding will be easy.

1. The Correct Welding Position

Illustrated is the correct welding position for
right-handed people. (For left-handed people it is
opposite.)

Whenever possible, weld from left to right (if right­handed). This enables you to see clearly what you
are doing.

Hold the electrode at a slight angle as shown in
Figure B.5.

3. The Correct Arc Length

The arc length is the distance from the tip of the
electrode core wire to the base metal.

Once the arc has been established, maintaining the
correct arc length becomes extremely important. The
arc should be short, approximately 1/16 to 1/8” (1.6-

3.2mm) long. As the electrode burns off, the elec-

trode must be fed to the work to maintain correct arc
length.

The easiest way to tell whether the arc has the correct
length is by listening to its sound. A nice, short arc
has a distinctive, “crackling” sound, very much like
eggs frying in a pan. The incorrect, long arc has a
hollow, blowing or hissing sound.

4. The Correct Welding Speed

Figure B.5

2. The Correct Way to Strike An Arc

Be sure the work clamp makes good electrical contact
to the work.

Lower your headshield and scratch the electrode
slowly over the metal, and you will see sparks fly.
While scratching, lift the electrode 1/8” (3.2mm) and
the arc is established.

NOTE: If you stop moving the electrode while
scratching, the electrode will stick.

NOTE: Most beginners try to strike the arc by a fast
jabbing motion down on the plate. Result: They either
stick their electrode or their motion is so fast that they
break the arc immediately.

The important thing to watch while welding is the pud­dle of molten metal right behind the arc. DO NOT
WATCH THE ARC ITSELF. The appearance of the
puddle and the ridge where the molten puddle solidi­fies indicates correct welding speed. The ridge should
be approximately 3/8” (9.5mm) behind the electrode.

Most beginners tend to weld too fast, resulting in a
thin, uneven, “wormy” looking bead. They are not
watching the molten metal.

IMPORTANT: It is not generally necessary to weave
the arc forward, backward or sideways. Weld along at
a steady pace, and you will have an easier time.

NOTE: When welding on thin plate, you will find that
you have to increase the welding speed, whereas
when welding on heavy plate, it is necessary to go
more slowly to ensure fusion and penetration.

welded successfully in most cases; however, care
must be taken to follow proper procedures, including
preheating the metal to be welded and, in some
cases, carefully controlling the temperature during and
after the welding process. For further information on
identifying various types of steel and other metals,
and for proper procedures for welding them, we sug­gest you purchase a copy of “New Lessons in Arc
Welding” (See Book Division section).

Regardless of the type of metal being welded, in order
to get a quality weld, it is important that it be free of
oil, paint, rust or other contaminants.

Types of Welds

Five types of welding joints are: Butt Welds, Fillet
Welds, Lap Welds, Edge Welds and Corner Welds.

Of these, the Butt Weld and Fillet Weld are the most
common.

2. When you can strike an arc without sticking, prac­tice the correct arc length. Learn to distinguish it
by its sound.

3. When you are sure that you can hold a short,
crackling arc, start moving. Look at the molten
puddle constantly, and look for the ridge where the
metal solidifies.

4. Run beads on a flat plate. Run them parallel to the
top edge (the edge farthest away from you). This
gives you practice in running straight welds, and
also, it gives you an easy way to check your
progress. The 10th weld will look considerably bet­ter than the first weld. By constantly checking on
your mistakes and your progress, welding will soon
be a routine matter.

Common Metals

Most metals found around the farm or small shop are
low carbon steel, sometimes referred to as mild steel.
Typical items made with this type of steel include most
sheet metal, plate, pipe and rolled shapes such as
channels, angle irons and “I” beams. This type of
steel can usually be easily welded without special
precautions. Some steel, however, contains higher
carbon. Typical applications include wear plates,
axles, connecting rods, shafts, plowshares and
scraper blades. These higher carbon steels can be

Butt Welds

Butt Welds are the most widely used welds. Place
two plates side by side, leaving 1/16” (1.6mm) for thin
metal to 1/8” (3.2mm) for heavy metal space between
them in order to get deep penetration.

Tack the plates at both ends, otherwise the heat will
cause the plates to move apart. (See drawing).

Fillet Welds

When welding fillet welds, it is very important to hold
the electrode at a 45° angle between the two sides, or
the metal will not distribute itself evenly.

end view side view

90°

Watch the molten metal to be sure it distributes itself
evenly on both edges and in between the plates.

Penetration

Unless a weld penetrates close to 100%, a butt weld
will be weaker than the material welded together.

In this example, the total weld is only 1/2 the thickness
of the material; thus, the weld is only approximately
half as strong as the metal.

To make it easier to get the 45° angle, it is best to put
the electrode in the holder at a 45° angle, as shown.

Multiple Pass Welds

Make multiple pass horizontal fillets as shown in the
sketch. Put the first bead in the corner with fairly high
current. Hold the electrode angle needed to deposit
the filler beads as shown putting the final bead against
the vertical plate.

In this example, the joint has been flame beveled or
ground prior to welding so that 100% penetration
could be achieved. The weld, if properly made, is as
strong or stronger than the original metal.

Successive passes must be used to build up butt
welds on heavier metal.

POWER ARC 5000

Welding in the Vertical Position

Welding in the vertical position can be done either
vertical-up or vertical-down. Vertical-up is used
whenever a large, strong weld is desired.
Vertical-down is used primarily on sheet metal for fast,
low penetrating welds.

B-16

OPERATION

B-16

Vertical-Up Welding

The problem, when welding vertical-up, is to put the
molten metal where it is wanted and make it stay
there. If too much molten metal is deposited, gravity
will pull it downwards and make it “drip”. Therefore, a
certain technique has to be followed:

Long arc

Short arc

NOTE: Holder end of electrode
is lower than arc.

1. Use 1/8” (3.2mm) 90-115 amps or 3/32” (2.5mm)
70 amps AWS 6011.

2. When welding, the electrode should be kept hori­zontal or pointing slightly upwards. (See drawing
above).

8. When the arc is brought back to the now solidified
puddle, IT MUST BE SHORT, otherwise no metal
will be deposited, the puddle will melt again, and it
will “drip”.

9. It is important to realize that the process consists
of SLOW, DELIBERATE movements. There are
no fast motions.

Vertical-Down Welding

Vertical-down welds are applied at a fast pace. These
welds are therefore shallow and narrow, and are
excellent for sheet metal. Do not use the vertical­down technique on heavy metal. The welds will not
be strong enough.

1. Use 1/8” (3.2m) or 3/32” (2.5mm) AWS 6011.

3. The arc is struck and metal deposited at the bot­tom of the two pieces to be welded together.

4. Before too much molten metal is deposited, the arc
is SLOWLY moved 1/2-3/4” (12-20mm) upwards.
This takes the heat away from the molten puddle,
which solidifies. (If the arc is not taken away soon
enough, too much metal will be deposited, and it
will “drip”.)

5. The upward motion of the arc is caused by a very
slight wrist motion. Most definitely, the arm must
not move in and out, as this makes the entire
process very complicated and difficult to learn.

6. If the upward motion of the arc is done correctly
with a wrist motion, the arc will automatically
become a long arc that deposits little or no metal.
(See drawing above.)

7. During this entire process, the ONLY thing to
watch is the molten metal. As soon as it has solidi­fied, the arc is SLOWLY brought back, and another
few drops of metal are deposited. DO NOT
FOLLOW THE UP AND DOWN MOVEMENT OF
THE ARC WITH YOUR EYES. KEEP THEM ON
THE MOLTEN METAL.

2. On thin metal use 70-75 amps.
(14 ga. 75 A - 16 ga. 60 A.)

3. Hold the electrode in a 30-45° angle with the tip of
the electrode pointing upwards.

4. Hold a VERY SHORT arc, but do not let the elec­trode touch the metal.

5. An up and down whipping
motion will help prevent
burn-through on very thin plate.

Very

30°-40°

6. Watch the molten metal carefully.

The important thing is to continue lowering the entire
arm as the weld is made so the angle of the electrode
does not change. Move the electrode fast enough so
that the slag does not catch up with the arc.

Overhead Welding

Various techniques are used for overhead welding.
However, in the interest of simplicity for the inexperi­enced welder, the following technique will probably
take care of his needs for overhead welding:

1. Use 1/8” (3.2mm) 90-105 A or 3/32” (2.5mm) 70 A
AWS 6011 electrode on AC.

2. Put the electrode in he holder so it sticks straight
out.

3. Hold the electrode at an angle approximately 30°
off vertical, both seen from the side and seen from
end. (See drawing below.)

Side View

End View

30°

30°

It is important to hold a VERY SHORT arc. (A long
arc will result in falling molten metal; a short arc will
make the metal stay.)

If necessary, and this is dictated by the appearance of
the molten puddle, a slight back and forth whipping
technique may be used to prevent “dripping”.

4. Move rapidly enough to stay ahead of the molten
slag. A whipping technique may be used to further
minimize burn through.

5. If you have a choice, use lap joints rather than fil­lets or butts; the double thickness effect of a lap
joint makes it much easier to weld without burning
through.

Hardfacing (To Reduce Wear)

There are several kinds of wear. The two most often
encountered are:

1. Metal to Ground Wear: Plowshares, bulldozer
blades, buckets, cultivator shares, and other metal
parts moving in the soil.

2. Metal to Metal Wear: Trunnions, shafts, rollers and
idlers, crane and mine car wheels, etc.

Each of these types of wear demands a different kind
of hardfacing electrode.

When applying the proper electrode, the service life of
the part will in most cases be more than double. For
instance, hardfacing of plowshares results in 3-5 times
more acreage plowed.

Welding Sheet Metal

Welding sheet metal presents an additional problem­burn through. Follow these simple rules:

1. Hold a very short arc. This, together with the prop­er travel speed, will eliminate burn through.

2. Use 1/8” (3.2mm) or 3/32” (2.5mm) AWS 6011.

3. Use low amperage. 75 A for 1/8” (3.2mm) elec­trode, 70 A for 3/32” (2.5mm) electrode.

POWER ARC 5000

How to Hardface the Sharp Edge (Metal to Ground
Wear)

1. Grind the share, approximately one inch along the
edge, so the metal is bright and clean.

2. Place the share on an incline of approximately
20-30°. The easiest way to do this is to put one
end of the share on a brick. (See drawings) Most
users will want to hardface the underside of the
share, but some might find that the wear is on the
top side. The important thing is to hardface the
side that wears.

3. Use 1/8” (3.2mm) Wearshield at 80-100 A. Strike
the arc about one inch from the sharp edge.

4. The bead should be put on with a weaving motion,
and it should be 1/2-3/4” (12.7-19.0mm) wide. Do
not let the arc blow over the edge, as that will dull
the edge. (See drawing below.)

5. Use the back-stepping method. Begin to weld 3”
(76mm) from the heel of the share and weld to the
heel. The second weld will begin 6” (152mm) from
the heel, the third weld 9” (229mm) from the heel,
etc.

B-18

When breaking
the weld stays on
one piece

To overcome this, the welding operator has two
choices:

1. Preheat the entire casting to 500-1200°F (260­649°C). If the cast iron is hot before welding, there
will be no sudden chilling which creates brittle
white cast iron. The entire casting will cool slowly.

2. Weld 1/2” (12.7mm) at a time, and do not weld at
that spot again until the weld is cool.

This way, no large amount of heat is put into the
mass.

Backstepping greatly reduces the chances for crack­ing of the share, and it also greatly reduces warping.

NOTE: The entire process is rather fast. Many begin­ners go much too slowly when hardfacing plowshares,
running the risk of burning through the thin metal.

Welding Cast Iron

When welding on a piece of cold cast iron, the
tremendous heat from the arc will be absorbed and
distributed rapidly into the cold mass. This heating
and sudden cooling creates WHITE, BRITTLE cast
iron in the fusion zone. (See drawing below.)

Most inexperienced welders will probably use the sec­ond method, because they have no way of preheating
large castings. Smaller castings can easily (and
should) be preheated before welding. A forge, stove,
fire, or the Arc Torch are all excellent means of pre­heating.

When using the 1/2” (12.7mm) at a time method, it is
recommended to start 1/2” (12.7mm) away from the
previous bead and weld into the previous bead. This
is called backstepping.

After welding Cast Iron, protect the casting against
fast cooling. Put it in a container of warm, dry sand or
lime.

If sand or lime is not available, cover it with sheet
metal or any other non-flammable material that will
diminish drafts and retain heat.

This is the reason why welds in cast iron break.
Actually, one piece of the broken cast iron has the
entire weld on it and the other piece has no weld on it.
(See drawing below.)

POWER ARC 5000

Cast Iron Plate Preparation

Wherever practical, the joint to be welded should be
“veed” out by grinding or filing to give complete pene­tration as shown in figures (a), (b) and (c) below. This
is especially important on thick castings where maxi­mum strength is required. In some instances a back-

(3.2mm) or more, as shown in figure (b).

On sections where only a sealed joint is required and
strength is not important, the joint may be welded after
slightly veeing out the seam as shown in figure (d)
below.

Selecting Electrodes

Which electrode is best for the particular job . . . how
do you use it? These are important questions
because the cost, quality, and appearance of your
work depends on proper electrode selection and appli­cation. MILD STEEL ELECTRODES may be classi­fied into the following groups:

This group includes electrodes which have a moder­ately forceful arc and deposit rates between those of
the out-of-position and high-deposit electrodes.

They are primarily general purpose production elec­trodes especially for downhill fillets and laps or short
and irregular welds that change direction or position.
They are also widely used in maintenance and recom­mended for sheet metal fillet and lap welds. Motion
“D” (see drawing) is generally used for vertical-up
welding, but motions “A” and “B” are also suitable.

Low Hydrogen Group (Stable-Arc E7018)

These electrodes are generally called “low hydrogen”.
The name comes from the fact that their coating
contains little hydrogen in either moisture or chemical
form. Low hydrogen electrodes offer these benefits:
outstanding crack resistance, lowest porosity on
sulphur bearing steels, and X-ray quality deposit capa­bility. Thus, they are the first choice when welding
“problem” steels. E7018 can be used in all positions,
with Motion “C” (below) recommended for the first
pass on vertical-up welds. NEVER use a whipping
technique or a long arc with these electrodes.
ALWAYS fill craters by drawing electrode away slowly.
ALWAYS keep these electrodes dry. Electrodes,
when not used within a few hours after a container is
opened, must be stored in heated cabinets.

Out-of-Position Group (AWS E6011)

This group includes electrodes which have a snappy,
deep penetrating arc and fast freezing deposits.

These electrodes are used for general purpose, all­position fabrication and repair welding. They are also
the best choice for pipe welding and sheet metal butt,
corner, and edge welds. They can be used for repair
work when dirt, grease, plating or paint cannot be
completely cleaned from the steel. These electrodes
are typically used with motions “A” and “B” (see draw­ing) for the first pass on vertical-up welds.

SAFETY PRECAUTIONS

WARNING

• Have qualified personnel do all maintenance and
troubleshooting work.

• Turn the engine off before working inside the
machine.

• Remove guards only when necessary to perform
maintenance and replace them when the mainte­nance requiring their removal is complete.

• If guards are missing from the machine, get
replacements from a Lincoln Distributor. See the
EXPLODED VIEW AND PARTS LIST at the back of
this manual.

Read the Safety Precautions in the front of this manu­al and in the Briggs & Stratton Operating and
Maintenance Instructions manual before working on
the POWER ARC 5000.

Keep all equipment safety guards, covers, and
devices in position and in good repair. Keep your
hands, hair, clothing, and tools away from the recoil
housing, fans, and all other moving parts when start­ing, operating, or repairing this machine.

OIL: Check the oil level after every 5
hours of operation or daily. BE SURE
TO MAINTAIN THE OIL LEVEL.

Change the oil the first time after 5 hours of oper­ation. Then, under normal operating conditions,

change the oil after every 50 hours or once a year,
whichever occurs first. If the engine is operated
under heavy load or in high ambient temperatures,
change the oil every 25 hours.

Drain the oil from the drain plug located on the side of
the engine block or from the drain plug located at the
bottom of the engine cover on the generator end.
Remove the oil dip-stick and add 1.5 quarts of oil.
Check the level with the dip-stick. Do not overfill.
Use the grade and viscosity recommended in the

Engine Owner’s Manual.
