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.

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.

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.

5. b. The operation of welding fume control equipment is affected
by various factors including proper use and positioning of
the equipment, maintenance of the equipment and the spe­cific welding procedure and application involved. Worker
exposure level should be checked upon installation and
periodically thereafter to be certain it is within applicable
OSHA PEL and ACGIH TLV limits.

5.c.

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.d. 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.

WELDING and CUTTING
SPARKS can
cause fire or explosion.

6.a.

Remove fire hazards from the welding area.

If this is not possible, cover them to prevent

Remember that welding sparks and hot
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.

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.

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.

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.

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.

MACHINE GROUNDING

Because this portable engine driven welder or generator
creates it’s own power, it is not necessary to connect it’s
frame to an earth ground, unless the machine is connected
to premises wiring (your home, shop, etc.).

In general, if the machine is to be grounded, it should be
connected with a #8 or larger copper wire to a solid earth
ground such as a metal water pipe going into the ground for
at least ten feet and having no insulated joints, or to the
metal framework of a building which has been effectively
grounded. The National Electrical Code lists a number of
alternate means of grounding electrical equipment. A
machine grounding stud marked with the symbol is pro­vided on the front of the welder.

SPARK ARRESTER

Some federal, state, or local laws may require that gasoline
engines be equipped with exhaust spark arresters when
they are operated in certain locations where unarrested
sparks may present a fire hazard. The standard muffler
included with this welder does not qualify as a spark
arrester. When required by local regulations, the K894-1
spark arrester must be installed and properly maintained.

CAUTION

An incorrect arrester may lead to damage to the engine
or adversely affect performance.

--------------------------------------------------------------------------------

TOWING

The recommended trailer for use with this equipment for
road, in-plant and yard towing by a vehicle
K957-1. If the user adapts a non-Lincoln trailer, he must
assume responsibility that the method of attachment and
usage does not result in a safety hazard nor damage the
welding equipment. Some of the factors to be considered
are as follows:

(1)

is Lincoln’s

WARNING

To prevent dangerous electric shock, other equipment
to which this engine driven welder supplies power
must:

• be grounded to the frame of the welder using a

grounded type plug or be double insulated.
Do not ground the machine to a pipe that carries
explosive or combustible material.

-------------------------------------------------------------------------------­When this welder is mounted on a truck or trailer, it’s frame
must be electrically bonded to the metal frame of the vehi­cle. Use a #8 or larger copper wire connected between the
machine grounding stud and the frame of the vehicle.

Where this engine driven welder is connected to premises
wiring such as that in your home or shop, it’s frame must be
connected to the system earth ground. See further connec­tion instructions in the section entitled “Standby Power
Connections”, as well as the article on grounding in the lat­est National Electrical Code and the local code.

RANGER 3 PHASE

1. Design capacity of trailer vs. weight of Lincoln equipment
and likely additional attachments.

2. Proper support of, and attachment to, the base of the

welding equipment so there will be no undue stress to
the framework.

3. Proper placement of the equipment on the trailer to

insure stability side to side and front to back when
being moved and when standing by itself while
being operated or serviced.

4. Typical conditions of use, i.e., travel speed; rough-

ness of surface on which the trailer will be operat­ed; environmental conditions.

5. Conformance with federal, state and local laws

Fill the fuel tank with clean, fresh, lead-free gasoline.
Observe fuel gauge while filling to prevent overfilling.

Make certain that the oil filler cap is tightened securely.
Refer to the engine Owner’s Manual for specific oil recom­mendations.

BATTERY CONNECTIONS

-------------------------------------------------------------------------------

This welder is shipped with the negative battery cable dis­connected. Make sure that the Engine Switch is in the
“STOP” position and attach the disconnected cable securely
to the negative battery terminal before attempting to operate
the machine. If the battery is discharged and does not have
enough power to start the engine, see the battery charging
instructions in the Battery section.

NOTE: This machine is furnished with a wet charged bat­tery; if unused for several months, the battery may require a
booster charge. Be careful to charge the battery with the
correct polarity.

WELDING OUTPUT CABLES

With the engine off, connect the electrode and work cables
to the studs provided. These connections should be
checked periodically and tightened if necessary. Loose con­nections will result in overheating of the output studs.

When welding at a considerable distance from the welder,
be sure you use ample size welding cables. Listed below
are copper cable sizes recommended for the rated current
and duty cycle. Lengths stipulated are the distance from the
welder to work and back to the welder again. Cable sizes
are increased for greater lengths primarily for the purpose of
minimizing cable voltage drop.

WARNING

• Damage to the fuel tank may cause
fire or explosion. Do not drill holes
in the RANGER 3 PHASE base or
weld to the RANGER 3 PHASE base.

CAUTION

Use caution as the electrolyte is a strong acid
that can burn skin and damage eyes.

ANGLE OF OPERATION

INSTALLATION

Muffler Relocation

A-4

Internal combustion engines are designed to run in a
level condition which is where the optimum perfor­mance is achieved. The maximum angle of operation
for the engine is 15 degrees from horizontal in any
direction. If the engine is to be operated at an angle,
provisions must be made for checking and maintain­ing the oil at the normal (FULL) oil capacity in the
crankcase in a level condition.

When operating at an angle, the effective fuel capaci­ty will be slightly less than the specified 9 gallons (34
Liters).

LIFTING

The RANGER 3 PHASE weighs approximately 575
lbs.(261kg) with a full tank of gasoline. A lift bail is
mounted to the machine and should always be used
when lifting the machine.

WARNING

• Lift only with equipment of ade­quate lifting capacity.

• Be sure machine is stable when lift­ing.

• Do not lift this machine using lift
bail if it is equipped with a heavy
accessory such as trailer or gas
cylinder.

FALLING • Do not lift machine if lift bail is

EQUIPMENT can damaged.

cause injury. • Do not operate machine while

suspended from lift bail.

--------------------------------------------------------------------------------

HIGH ALTITUDE OPERATION

At higher altitudes, Welder output de-rating may be neces­sary. For maximum rating, de-rate the welder output 3.5%
for every 1000ft. (305m) above 3000ft. (914m).

WARNING

•

Shut off welder and allow muffler to cool before
touching muffler.

------------------------------------------------------------------------

The RANGER 3 PHASE is shipped with the exhaust
coming out on the left side. The exhaust can be
changed to the opposite side by removing the two
screws that hold the exhaust port cover in place and
installing the cover on the opposite side. (Operating
the RANGER 3 PHASE without the cover in place will
result in a higher noise level and no increase in
machine output.)

LOCATION / VENTILATION

The welder should be located to provide an unrestrict­ed flow of clean, cool air to the cooling air inlets and to
avoid heated air coming out of the welder recirculating
back to the cooling air inlet. Also, locate the welder so
that engine exhaust fumes are properly vented to an
outside area.

STACKING

RANGER 3 PHASE machines cannot be stacked.

CONNECTION OF LINCOLN ELECTRIC
WIRE FEEDERS

WARNING

Shut off welder before making any electrical
connections.

-----------------------------------------------------------------------­WIRE FEED (CONSTANT VOLTAGE)
CONNECTION OF LN-15 ACROSS-THE-ARC WIRE
FEEDER

The LN-15 has an internal contactor and the electrode
is not energized until the gun trigger is closed. When
the gun trigger is closed the wire will begin to feed
and the welding process is started.

If operation will consistently be at altitudes above 5,000 ft.
(1525m), a carburetor jet designed for high altitudes should
be installed. This will result in better fuel economy, cleaner
exhaust and longer spark plug life. It will not give increased
power. Contact your local authorized engine service shop
for high altitude jet kits that are available from the engine
manufacturer.

CAUTION

Do not operate with a high altitude jet installed at alti­tudes below 5000 ft. This will result in the engine run­ning too lean and result in higher engine operating
temperatures which can shorten engine life.

----------------------------------------------------------------------

RANGER 3 PHASE

a. Shut the welder off.
b. Set the Polarity switch to the desired polarity,

either DC (-) or DC (+).

c. Attach the single lead from the front of the LN-15

to work using the spring clip at the end of the lead.
This is a control lead to supply current to the wire
feeder motor; it does not carry welding current.

d. Set the “RANGE” switch to the “WIRE FEED-CV”

position
e. Place the Engine switch in the “Auto Idle” position.
f. Adjust the wire feed speed at the LN-15 and adjust

the welding voltage with the output “CONTROL” at
the welder.

Note: LN-15 Control Cable model will not work with

the RANGER 3 PHASE.

Output “CONTROL” must be set above 3.
