WARNING
Mar ‘95
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.
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.
1.h. To avoid scalding, do not remove the
radiator pressure cap when the engine is
hot.
CALIFORNIA PROPOSITION 65 WARNINGS

SAFETY
ii
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.
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.
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.
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.
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.
5.e. Also see item 1.b.

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

SAFETY
iii
Mar ‘95
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.
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 cir-
cuits. 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 suiv-
antes:
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.
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 ray-
onnement 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, pan-
talons 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.
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 lev-
age, 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.
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 debranch-
er à l’interrupteur à la boite de fusibles.
4. Garder tous les couvercles et dispositifs de sûreté à leur
place.

GENERAL DESCRIPTION
The Classic
®
III and Classic
®
III D are heavy duty,
engine driven, DC arc welding power sources capable
of providing constant current output for stick welding
or DC TIG welding. These welders are wound with all
copper coils, rated at 300 amps/32 Volts, and provide
other Classic features such as improved door latches
and stainless hinges. With the addition of the optional
K623-1 Wire Feed Module
™
, the Classic III or Classic
III D will provide constant voltage output for running
the LN-7, LN-23P, or LN-25 wire feeders. (The Wire
Feed Module is factory installed on the K1428-3 and
K1433-2).
The Classic III D has Diesel Engine Protection. In the
event of sudden low oil pressure or high coolant tem-
perature, the engine immediately shuts down. The
Classic III & Classic III D have a current range of 40-
350 DC amps with output ratings as follows:
These units are also capable of providing 3 kVA of
115/230 volts of 60 cycle AC auxiliary power.
The Classic III unit uses the Continental TM27
®
industrial water-cooled Gasoline engine, while the
Classic III D uses the Continental TMD27
®
industrial
water-cooled Diesel engine.
DESIGN FEATURES
Control Panel
Both the engine and the welder controls are located
on one recessed panel at the exciter end of the
machine. The welder controls consist of a five step
“Current Range Selector” switch and a “Fine Current
Adjustment” rheostat. Each welder is equipped with a
“Start” button, an “Ignition” switch and an “Idler” con-
trol switch. The diesel version comes with a “Glow
Plug” feature for easier cold weather starting.
The control panels also contain an engine tempera-
ture gauge (diesel only), a battery charging ammeter,
an oil pressure gauge (oil pressure light on the gaso-
line version), two three prong grounding type recepta-
cles and circuit breakers for auxiliary power, and a
choke control (gasoline version only).
All Copper Windings - For long life and dependable
operation.
Engine Idler - Both the Classic III & III D are
equipped with an electronic automatic engine idler. It
automatically increases and decreases engine speed
when starting and stopping welding or using aux-
iliary power. A built-in 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 full speed position when desired.
Auxiliary Power - 3.0 kVA of nominal 115/230V,
60Hz, AC. Output voltage is maintained within ± 10%
at all loads up to rated capacity. (See Optional
Features for Power Plug Kits.)
Welder Enclosure - The complete welders are rubber
mounted on a rugged steel “C” channel base.
The output terminals are placed at the side of the
machines so that they are protected by the door. The
output terminals are labeled (+) and (-).
Cranking System - A 12 volt electric starter is stan-
dard.
Air Cleaner - Heavy duty two stage dry type.
Muffler - A muffler and rain cap are standard.
Engine Hour Meter - A meter to record hours of oper-
ation.
Diesel Engine Protection - The system shuts the
diesel engine down in the event of sudden low oil
pressure or high coolant temperature.
Carburetor Deicing Kit
Classic III Welders are equipped with a kit, that
prevents carburetor icing when outside temperature is
60°F/15.5°C or lower.

PRE-OPERATION INSTALLATION
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 mufflers included with these welders do not
qualify as spark arresters. When required by local
regulations, suitable spark arresters must be installed
and properly maintained.
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.
The welder should be located to provide an unrestrict-
ed flow of clean, cool air. Also, locate the welder so
that engine exhaust fumes are properly vented to an
outside area.
STACKING
Classic III and III D machines cannot be stacked.
ANGLE OF OPERATION
To achieve optimum engine performance the Classic
III and III D should be run in a level position. The max-
imum angle of operation for the TM27 and TMD27
engines is 60 degrees in a direction to cause the air
intake manifold to be angled up, 45 degrees for the air
intake manifold to be angled down, and 50 degrees
for the welder control panel to be angled up or down.
If the engine is to be operated at an angle, provisions
must be made for checking and maintaining the oil
level at the normal (FULL) oil capacity in the
crankcase. When operating the welder at an angle,
the effective fuel capacity will be less than the speci-
fied 15 gallons (57 Ltrs.).
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. (If an
older portable welder does not have a grounding stud,
connect the ground wire to an unpainted frame screw
or bolt.) 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.
Do not attempt to use this equipment until you
have thoroughly read the engine manufacturer’s
manual supplied with your welder. It includes
important safety precautions, detailed engine
starting, operating and maintenance instructions,
and parts lists.

Lift Bail
A lift bail is provided for lifting with a hoist.
Trailer (See Optional Features)
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 dam-
age the welding equipment. Some of the factors to be
considered are as follows:
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
ensure 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, likely maintenance.
5. Conformance with federal, state and local laws.

6. If engine fails to start in 60 seconds, the reset
button will pop out. Wait 30 seconds, reset
and repeat the above procedure.
7. Allow engine to run at high idle speed for several
minutes to warm the engine. Cold engines tend
to run at a speed too slow to supply the voltage
required for proper idler operation.
Note: Extreme cold weather starting may require
longer glow plug operation.
Under NO
conditions should ether or other
starting fluids be used in conjunction with the
glow plugs. This may cause an explosion or fire!
------------------------------------------------------------------------
Stopping the Engine
1. Turn the Ignition control switch “Off”
At the end of each day’s welding, refill the fuel tank to
minimize moisture condensation in the tank. Also,
running out of fuel tends to draw dirt into the fuel sys-
tem.
When hauling the welder between job sites, close the
fuel feed valve beneath the fuel tank. In gasoline
engines, failure to turn fuel off when traveling can
cause carburetor flooding and difficult starting at the
new job site.
In diesel engines, 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. See the Engine Operating Manual.

CLASSIC III AND IIID
WELDER OPERATION
Duty Cycle
The NEMA output rating of the Classic III &
Classic III D are each 300 amperes at 32 arc volts on
a 50% duty cycle (consult Specifications in this manual
for alternate ratings). Duty cycle is based on a ten
minute period; thus, the welder can be loaded at rated
output for five minutes out of every ten minute period.
Control of Welding Current
DO NOT TURN THE “CURRENT RANGE SELEC-
TOR” WHILE WELDING because the current may
arc between the contacts and damage the switch.
------------------------------------------------------------------------
The “Current Range Selector” provides five overlap-
ping 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 pre-
ferred 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.
When a forceful “digging” arc is required, usually for
vertical and overhead welding, use a higher “Current
Range Selector” setting and lower open circuit volt-
age. 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 tech-
niques at settings at the lower end of the open circuit
voltage range.
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.
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 posi-
tions as follows:
1. In the “High” position, the idler is off, and the
engine high speed is controlled by the governor.
2. In the “Auto” / position, the idler oper-
ates as follows:
a. When welding or drawing power for lights or tools
(approximately 100-150 watts minimum) from the
receptacles, the engine operates at full 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.
c. If the welding or power load is not re-started
before the end of the time delay, the idler reduces
the engine to low idle speed.
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.

MAINTENANCE
General Instructions
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 cur-
rent control through its entire range frequently. Good
practice is to turn the handle from maximum to mini-
mum 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.
4. When necessary, remove the sediment bowl, if so
equipped, from beneath the fuel tank and clean out
any accumulated dirt and water.
5. Follow the engine service schedule in this manual
and the detailed maintenance and troubleshooting in
the engine manufacturer’s manual.
Cooling System
The Classic III & III D are each equipped with a pres-
sure radiator. Keep the radiator cap tight to prevent
loss of coolant. Clean and flush the cooling system
periodically to prevent clogging the passage and over-
heating the engine. When antifreeze is needed,
always use the permanent type. Capacity = 9.3 qts.
Bearings
This welder is equipped with a double-shielded ball
bearing having sufficient grease to last indefinitely
under normal service. Where the welder is used con-
stantly or in excessively dirty locations, it may be nec-
essary to add one half ounce of grease per year. A
pad of grease one inch wide, one inch long, and one
inch high weighs approximately one half ounce. Over-
greasing is far worse than insufficient greasing.
When greasing the bearings, keep all dirt out of the
area. Wipe the fittings completely clean and use
clean equipment. More bearing failures are caused
by dirt introduced during greasing than from insuffi-
cient grease.
Commutator and Brushes
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 rotat-
ing 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. NOTE: If
the welder is used in dirty or dusty locations, or if the
welder is not used for prolonged periods of time, it
may be necessary to clean the commutator and slip
rings more often.
CLASSIC III AND IIID
Have qualified personnel do the maintenance
work. Turn the engine off before working inside
the machine. In some cases, it may be neces-
sary to remove safety guards to perform
required maintenance. Remove guards only
when necessary and replace them when the
maintenance requiring their removal is com-
plete. Always use the greatest care when work-
ing near moving parts.
Do not put your hands near the engine cooling
blower fan. If a problem cannot be corrected by
following the instructions, take the machine to
the nearest Lincoln Field Service Shop.

MAINTENANCE
D-2
Replace brushes when they wear within 1/4” 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 mainte-
nance man 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 sandpa-
per 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
Before doing electrical work on the idler printed
circuit board, disconnect the battery.
------------------------------------------------------------------------
When installing a new battery or using a jumper bat-
tery 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
printed circuit board can result from incorrect connec-
tion.
1. The solenoid plunger must work freely and not
bind. Dust the plunger about once a year with
graphite powder.
2. Proper operation of the idler requires good ground-
ing of the printed circuit board, reed switch, and bat-
tery.
3. If desired, the welder can be used without automat-
ic idling by setting the “Idler” switch to the “High”
position.
Nameplates
Whenever routine maintenance is performed on this
machine - or at least yearly - inspect all nameplates
and labels for legibility. Replace those which are no
longer clear. Refer to the parts list for the replace-
ment item number.
