BE SURE THAT ALL INSTALLATION, OPERATION,
MAINTENANCE AND REPAIR PROCEDURES ARE
PERFORMED ONLY BY QUALIFIED INDIVIDUALS.

SAFETY

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.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.

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

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.

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.

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.

3

SAFETY

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

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.

between the

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 within applicable OSHA PEL and
ACGIH TLV limits 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 vapors
coming from degreasing, cleaning or spraying operations. The
heat and rays of the arc can react with solvent vapors to form
phosgene, a highly toxic gas, and other irritating products.

3.j. Also see It ems 6.c. and 8.

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

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

5.e. 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.

5.f. Also see item 1.b.

cause

SAFETY

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 the
welding sparks from starting a fire. 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 though they have been
“cleaned”. For information, purchase “Recommended Safe
Practices for the Preparation for Welding and Cutting of
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.

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

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, “Precautions for
Safe Handling of Compressed Gases in

Cylinders,” available
from the Compressed Gas Association 1235 Jefferson Davis
Highway, Arlington, VA 22202.

FOR ELECTRICALLY
POWERED EQUIPMENT.

8.a. Turn off input power using the disconnect
switch at the fuse box before working on the
equipment.

8.b. Install equipment in accordance with the U.S. National Electrical
Code, all local codes and the manufacturer’s recommendations.

6.I. Read and follow NFPA 51B “ Standard for Fire Prevention During
Welding, Cutting and Other Hot Work”, available from NFPA, 1
Batterymarch Park, PO box 9101, Quincy, Ma 022690-9101.

6.j. Do not use a welding power source for pipe thawing.

SAFETY

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 LʼArc

1. Protegez-vous contre la secousse électrique:

a. Les circuits à lʼélectrode 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 sʼisoler 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 lʼeau 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 sʼapplicuent aussi au pistolet de
soudage.

6. Eloigner les matériaux inflammables ou les recouvrir afin de
prévenir tout risque dʼincendie 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 dʼincendie.

8. Sʼassurer que la masse est connectée le plus prés possible
de la zone de travail quʼil est pratique de le faire. Si on place
la masse sur la charpente de la construction ou dʼautres
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 dʼincendie ou dʼechauffement des chaines et des
câbles jusquʼà ce quʼils 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
dʼopérations de dégraissage, nettoyage ou pistolage. La
chaleur ou les rayons de lʼarc 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 nʼimporte quelle partie
du corps.

3. Un coup dʼarc peut être plus sévère quʼun coup de soliel,
donc:

a. Utiliser un bon masque avec un verre filtrant approprié

ainsi quʼun verre blanc afin de se protéger les yeux du ray­onnement de lʼarc et des projections quand on soude ou
quand on regarde lʼarc.

b. Porter des vêtements convenables afin de protéger la

peau de soudeur et des aides contre le rayonnement de
lʻarc.

c. Protéger lʼautre personnel travaillant à proximité au

soudage à lʼaide dʼécrans appropriés et non-inflammables.

4. Des gouttes de laitier en fusion sont émises de lʼarc de
soudage. Se protéger avec des vêtements de protection libres
de lʼhuile, 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 lʼon 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
lʼélectricité 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, Iʼinstallation et lʼentretien du poste seront
effectués par un électricien qualifié.

3. Avant de faires des travaux à lʼinterieur de poste, la debranch­er à lʼinterrupteur à la boite de fusibles.

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

Engine Idler - The Classic®300HE is equipped with

an electronic automatic engine idler. It automatically
increases and decreases engine speed when starting
and stopping welding or using auxiliary power. A built­in time delay permits changing electrodes before the
engine slows to its low idle speed. The “Idler” control
switch on the panel locks the idler in high idle position
when desired.

Auxiliary Power - 3.0 kVA of nominal 120/240V,
60Hz, AC. Output voltage is maintained within ± 10%
at all loads up to rated capacity. (See Optional
Features for Power Plug Kit.)

GFCI - Protects the 20 amp, 120V duplex receptacle.
See the Maintenance Section for detailed informa­tion on testing and resetting of the GFCI.

120 V DUPLEX RECEPTACLE AND GFCI

A GFCI protects the 120V auxiliary power
receptacle.

A GFCI (Ground Fault Circuit Interrupter) is a device to
protect against electric shock should a piece of defective
equipment connected to it develop a ground fault. If this
situation should occur, the GFCI will trip, removing volt­age from the output of the receptacle. If a GFCI is tripped
see the MAINTENANCE section for detailed information
on testing and resetting it. A GFCI should be properly
tested at least once every month.

EXHAUST SPARK ARRESTER

Some federal, state or local laws may require that
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, a suitable spark arrester must be installed
and properly maintained.

CAUTION

Use of an incorrect arrester may lead to engine damage
or performance loss. Contact the engine manufacturer
for specific recommendations.

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

LOCATION / VENTILATION

Always operate the welder with the doors closed.
Leaving the doors open changes the designed air flow
and may cause overheating.

MACHINE GROUNDING

According to the United States National Electrical Code, the
frame of this portable generator is not required to be grounded
and is permitted to serve as the grounding means for cord
connected equipment plugged into its receptacle.

Some state, local, or other codes or unusual operating circum­stances may require the machine frame to be grounded. It is
recommended that you determine the extent to which such
requirements may apply to your particular situation and follow
them explicitly. A machine grounding stud marked with the
symbol is provided on the welding generator frame foot. 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
U.S. National Code lists a number of alternate means of
grounding electrical equipment.

2. Turn the “IGNITION” switch to “ON”.

3. Press the Glow Plug button for 20 to 30 seconds.
(maximum 60 seconds).

4. Press the Glow Plug button and the Start button at the
same time. When the engine starts running, release
both buttons. If the engine fails to start in 20 seconds,
wait 30 seconds and repeat the above procedure.

5. Observe the oil pressure. If no pressure shows within
30 seconds, stop the engine and consult the engine
operating manual. To stop the engine, turn the “IGNI­TION” switch to “OFF”.

6. If the engine protection warning light comes on during
cranking or after start up, the “IGNITION” switch must
be turned “OFF” to reset the engine protection system.

7. Allow the engine to run at high idle speed for several
minutes to warm the engine. Stop the engine and
recheck the oil level, after allowing sufficient time for
the oil to drain into the pan. If the level is down, fill it to
the full mark again. The engine controls were properly
set at the factory and should require no adjusting when
received.

CLASSIC®300HE

With a fully charged battery and the proper weight oil,
the engine should start satisfactorily even down to
about -5°F (-20°C), it maybe desirable to install cold­starting aides.

Note: Extreme cold weather staring may require
longer glow plug operation.

WARNING

Under NO
starting fluids be used!

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

HIGH ALTITUDE OPERATION:

At higher altitudes, output derating may be necessary.
For maximum rating, derate the welder 4% for every
300 meters (984 ft.) above 1500 meters (4920 ft.).

Contact a Kubota Service Representative for any
engine adjustments that may be required.

STOPPING THE ENGINE

1. Turn the “IGNITION” switch to “OFF”

At the end of each dayʼs welding, check the crankcase
oil level, drain accumulated dirt and water from the
water separator and refill the fuel tank to minimize
moisture condensation in the tank. Also, running out
of fuel tends to draw dirt into the fuel system.

When hauling the welder between job sites, close the
valve on the water separator.

If the fuel supply is cut off or runs out while the fuel
pump is operating, air may be entrapped in the fuel
distribution system. If this happens, bleeding of the
fuel system may be necessary. Use qualified person­nel to do this per the instructions in the MAINTE­NANCE section of this manual.

ENGINE BREAK-IN

Lincoln Electric selects high quality, heavy-duty indus­trial engines for the portable welding machines we
offer. While it is normal to see a small amount of
crankcase oil consumption during initial operation,
excessive oil use, wet stacking (oil or tar like sub­stance at the exhaust port), or excessive smoke is not
normal.

B-2

OPERATION

B-2

Larger machines with a capacity of 350 amperes and
higher, which are operated at low or no-load condi­tions for extended periods of time are especially sus­ceptible to the conditions described above. To
accomplish successful engine break-in, most diesel­powered equipment needs only to be run at a reason­ably heavy load within the rating of the welder for
some period of time during the engineʼs early life.
However, if the welder is subjected to extensive light
loading, occasional moderate to heavy loading of the
engine may sometimes be necessary. Caution must
be observed in correctly loading a diesel/generator
unit.

1. Connect the welder output studs to a suitable
resistive load bank. Note that any attempt to
short the output studs by connecting the welding
leads together, direct shorting of the output studs,
or connecting the output leads to a length of steel
will result in catastrophic damage to the generator
and voids the warranty.

2. Set the welder controls for an output current and
voltage within the welder rating and duty cycle.
Note that any attempt to exceed the welder rating
or duty cycle for any period of time will result in
catastrophic damage to the generator and voids
the warranty.

3. Periodically shut off the engine and check the
crankcase oil level.

a 60% duty cycle (consult

for alternate ratings).

CAUTION

CONTROL OF WELDING CURRENT

DO NOT TURN THE “CURRENT RANGE SELEC­TOR” WHILE WELDING because the current may
arc between the contacts and damage the switch.

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

The “Current Range Selector” provides five overlap­ping current ranges. The “Fine Current Adjustment”
adjusts the current from minimum to maximum within
each range. Open circuit voltage is also controlled by
the “Fine Current Adjustment” permitting control of the
arc characteristics.

A high open circuit voltage setting provides the soft
“buttering” arc with best resistance to pop-outs pre­ferred for most welding. To get this characteristic, set
the “Current Range Selector” to the lowest setting that
still provides the current you need and set the “Fine
Current Adjustment” near maximum. For example: to
obtain 175 amps and a soft arc, set the “Current
Range Selector” to the 190-120 position and then
adjust the “Fine Current Adjustment” for 175 amps.

ELECTRIC SHOCK can kill.

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

• Insulate yourself from work and ground.

FUMES & GASES can be dangerous.

• Keep your head out of the fumes.

• Use ventilation or exhaust to remove

fumes from breathing zone.

WELDING SPARKS can cause fire or
explosion.

• Keep flammable material away.

ARC RAYS can burn.

• Wear eye, ear, and body protection.

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

CLASSIC®300HE

When a forceful “digging” arc is required, usually for
vertical and overhead welding, use a higher “Current
Range Selector” setting and lower open circuit volt­age. For example: to obtain 175 amps and a forceful
arc, set the “Current Range Selector” to the 240-160
position and the “Fine Current Adjustment” setting to
get 175 amps.

Some arc instability may be experienced with EXX10
electrodes when trying to operate with long arc tech­niques at settings at the lower end of the open circuit
voltage range.

CAUTION

DO NOT attempt to set the “Current Range Selector”
between the five points designated on the nameplate.

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

These switches have a spring loaded cam which
almost eliminates the possibility of setting this switch
between the designated points.

OPERATION

IDLER OPERATION

Start the engine with the “Idler” switch in the “High”
position. Allow it to run at high idle speed for several
minutes to warm the engine. See Specifications for
operating speeds.

The idler is controlled by the “Idler” toggle switch on
the welder control panel. The switch has two posi­tions as follows:

1. In the “High” position, the engine control unit

increases the engine to high idle speed.

2. In the “Auto” / position, the idler oper-

ates as follows:

a. When welding or drawing power for lights or tools

(approximately 100 watts minimum) from the recep­tacles, the engine operates at high idle speed.

b. When welding ceases or the power load is turned

off, a preset time delay of about 15 seconds starts.
This time delay cannot be adjusted.

B-3

The AC auxiliary power, supplied as a standard, has a
rating of 3.0 kVA of 120/240 VAC (60 hertz).

With the 3.0 KVA, 120/240 VAC auxiliary power, one
120V duplex protected by GFCI and one 240V duplex,
grounding type receptacle with 2 pole, 15 amp circuit
breaker.

The rating of 3.0 KVA permits a maximum continuous
current of 13 amps to be drawn from the 240 volt
duplex receptacle. 20 amps can be drawn from the
120 volt duplex receptacle. The total combined load of
all receptacles is not to exceed 3.0 KVA.

An optional power plug kit is available. When this kit is
specified, the customer is supplied with a plug for
each receptacle.

c. If the welding or power load is not re-started before

the end of the time delay, the engine control unit
reduces the engine to low idle speed.

AUXILIARY POWER

Start the engine and set the “IDLER” control switch to
the “High Idle” mode. Voltage is now correct at the
receptacles for auxiliary power. This must be done
before a tripped GFCI can be reset properly. See the
MAINTENANCE section for detailed information on
testing and resetting the GFCI.

GENERAL INSTRUCTIONS

4. Follow the engine service schedule in this manual

and the detailed maintenance and troubleshooting in
the engine manufacturerʼs manual.

COOLING SYSTEM

The Classic®300HE is equipped with a pressure radi­ator. Keep the radiator cap tight to prevent loss of
coolant. Clean and flush the cooling system periodi­cally to prevent clogging the passage and overheating
the engine. When antifreeze is needed, always use
the permanent type.

BEARINGS

This welder is equipped with a double synthetic
sealed ball bearing having sufficient grease to last
indefinitely under normal service.

COMMUTATOR AND BRUSHES

WARNING

Uncovered rotating equipment can be dangerous.
Use care so your hands, hair, clothing or tools do
not catch in the rotating parts. Protect yourself
from particles that may be thrown out by the rotat­ing armature when stoning the commutator.

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

Shifting of the commutator brushes may result in:

- Change in machine output

- Commutator damage

- Excessive brush wear

Periodically inspect the commutator, slip rings, and
brushes by removing the covers. DO NOT remove or
replace these covers while the machine is running.
Commutators and slip rings require little attention.
However, if they are black or appear uneven, have
them cleaned by an experienced maintenance man
using fine sandpaper or a commutator stone. Never
use emery cloth or paper for this purpose.

1. Blow out the welder and controls with an air hose at

least once every two months. In particularly dirty
locations, this cleaning may be necessary once a
week. Use low pressure air to avoid driving dirt into
the insulation.

2. “Current Range Selector” contacts should not be

greased. To keep the contacts clean, rotate the cur­rent control through its entire range frequently.
Good practice is to turn the handle from maximum
to minimum setting twice each morning before start­ing to weld.

3. Put a drop of oil on the “Current Range Selector”

shaft at least once every month.

CLASSIC®300HE

D-2

Replace brushes when they wear within 1/4”(3.5mm)
of the pigtail. A complete set of replacement brushes
should be kept on hand. Lincoln brushes have a
curved face to fit the commutator. Have an experi­enced maintenance person seat these brushes by
lightly stoning the commutator as the armature rotates
at full speed until contact is made across the full face
of the brushes. After stoning, blow out the dust with
low pressure air.

To seat slip ring brushes, position the brushes in
place. Then slide one end of a piece of fine sandpaper
between slip rings and brushes with the coarse side
against the brushes. With slight additional finger pres­sure on top of the brushes, pull the sandpaper around
the circumference of the rings - in direction of rotation
only - until brushes seat properly. In addition, stone
slip ring with a fine stone. Brushes must be seated
100%.

Arcing or excessive exciter brush wear indicates a
possible misaligned shaft. Have an authorized Field
Service Shop check and realign the shaft.

IDLER MAINTENANCE

CAUTION

Before doing electrical work, disconnect the bat­tery.

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

When installing a new battery or using a jumper bat­tery to start the engine, be sure the battery polarity is
connected properly. The correct polarity is negative
ground. Damage to the engine alternator and the
Engine Control Unit can result from incorrect connec­tion.

1. Proper operation of the idler requires good

grounding of the Engine Control Unit, current
sensing printed circuit board and battery.

2. If desired, the welder can be used without automat-

ic idling by setting the “Idler” switch to the “High”
position.

MAINTENANCE

GFCI TESTING AND RESETTING
PROCEDURE

The GFCI should be properly tested at least once
every month or whenever it is tripped. To properly test
and reset the GFCI :

• If the GFCI has tripped, first carefully remove any
load and check it for damage.

• If the equipment has been shut down, it must be
restarted.

• The equipment needs to be operating at high idle
speed and any necessary adjustments made on the
