WARNING

Mar ‘95

ELECTRIC AND MAGNETIC FIELDSmay 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, andwelders having a pacemaker should consult their physicianbefore welding.

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

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

2.d.1. Route the electrode and work cables together - Securethem 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 andwork 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 aspossible to the area being welded.

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

1.h. To avoid scalding, do not remove theradiator pressure cap when the engine ishot.

ARC RAYS can burn.4.a. Use a shield with the proper filter and cover

plates to protect your eyes from sparks andthe rays of the arc when welding or observingopen arc welding. Headshield and filter lensshould conform to ANSI Z87. I standards.

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

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

ELECTRIC SHOCK cankill.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 bareskin 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 fullarea of physical contact with work and ground.

In addition to the normal safety precautions, if weldingmust be performed under electrically hazardousconditions (in damp locations or while wearing wetclothing; on metal structures such as floors, gratings orscaffolds; when in cramped positions such as sitting,kneeling or lying, if there is a high risk of unavoidable oraccidental contact with the workpiece or ground) usethe 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 semiautomaticwelding gun are also electrically “hot”.

3.d. Always be sure the work cable makes a good electricalconnection with the metal being welded. The connectionshould 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 andwelding machine in good, safe operating condition. Replacedamaged insulation.

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

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

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

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

FUMES AND GASEScan be dangerous.5.a. Welding may produce fumes and gases

hazardous to health. Avoid breathing thesefumes and gases.When welding, keepyour head out of the fume. Use enoughventilation and/or exhaust at the arc to keep

fumes and gases away from the breathing zone. Whenwelding with electrodes which require specialventilation such as stainless or hard facing (seeinstructions on container or MSDS) or on lead orcadmium plated steel and other metals or coatingswhich produce highly toxic fumes, keep exposure aslow as possible and below Threshold Limit Values (TLV)using local exhaust or mechanical ventilation. Inconfined spaces or in some circumstances, outdoors, arespirator may be required. Additional precautions arealso required when welding on galvanized steel.

5.b. Do not weld in locations near chlorinated hydrocarbon vaporscoming from degreasing, cleaning or spraying operations.

The heat and rays of the arc can react with solvent vapors toform phosgene, a highly toxic gas, and other irritating products.

5.c. Shielding gases used for arc welding can displace air andcause 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 thisequipment and the consumables to be used, including thematerial safety data sheet (MSDS) and follow youremployer’s safety practices. MSDS forms are available fromyour welding distributor or from the manufacturer.

5.e. Also see item 1.b. Mar ‘95

FOR ELECTRICALLYpowered equipment.

8.a. Turn off input power using the disconnectswitch at the fuse box before working onthe equipment.

8.b. Install equipment in accordance with the U.S. NationalElectrical Code, all local codes and the manufacturer’srecommendations.

8.c. Ground the equipment in accordance with the U.S. NationalElectrical Code and the manufacturer’s recommendations.

CYLINDER may explodeif damaged.7.a. Use only compressed gas cylinders

containing the correct shielding gas for theprocess used and properly operatingregulators designed for the gas and

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

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

7.c. Cylinders should be located:• Away from areas where they may be struck or subjected tophysical damage.

• A safe distance from arc welding or cutting operations andany other source of heat, sparks, or flame.

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

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

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

7.g. Read and follow the instructions on compressed gascylinders, associated equipment, and CGA publication P-l,“Precautions for Safe Handling of Compressed Gases inCylinders,” available from the Compressed Gas Association1235 Jefferson Davis Highway, Arlington, VA 22202.

Mar ‘95

WELDING SPARKS cancause fire or explosion.6.a. Remove fire hazards from the welding area.

If this is not possible, cover them to preventthe welding sparks from starting a fire.Remember that welding sparks and hot

materials from welding can easily go through small cracksand openings to adjacent areas. Avoid welding nearhydraulic 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 hazardoussituations. Refer to “Safety in Welding and Cutting” (ANSIStandard Z49.1) and the operating information for theequipment being used.

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

6.d. Do not heat, cut or weld tanks, drums or containers until theproper steps have been taken to insure that such procedureswill not cause flammable or toxic vapors from substancesinside. They can cause an explosion even though they havebeen “cleaned”. For information, purchase “RecommendedSafe Practices for the Preparation for Welding and Cutting ofContainers and Piping That Have Held HazardousSubstances”, AWS F4.1 from the American Welding Society(see address above).

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

6.f. Sparks and spatter are thrown from the welding arc. Wear oilfree protective garments such as leather gloves, heavy shirt,cuffless trousers, high shoes and a cap over your hair. Wearear plugs when welding out of position or in confined places.Always wear safety glasses with side shields when in awelding area.

6.g. Connect the work cable to the work as close to the weldingarea as practical. Work cables connected to the buildingframework or other locations away from the welding areaincrease the possibility of the welding current passingthrough lifting chains, crane cables or other alternate cir-cuits. This can create fire hazards or overheat lifting chainsor cables until they fail.

PRÉCAUTIONS DE SÛRETÉPour votre propre protection lire et observer toutes les instructionset les précautions de sûreté specifiques qui parraissent dans cemanuel aussi bien que les précautions de sûreté générales suiv-antes:

Sûreté Pour Soudage A L’Arc1. Protegez-vous contre la secousse électrique:

a. Les circuits à l’électrode et à la piéce sont sous tensionquand la machine à souder est en marche. Eviter toujourstout contact entre les parties sous tension et la peau nueou les vétements mouillés. Porter des gants secs et sanstrous pour isoler les mains.

b. Faire trés attention de bien s’isoler de la masse quand onsoude dans des endroits humides, ou sur un planchermetallique ou des grilles metalliques, principalement dans les positions assis ou couché pour lesquelles une grandepartie du corps peut être en contact avec la masse.

c. Maintenir le porte-électrode, la pince de masse, le câblede soudage et la machine à souder en bon et sûr étatdefonctionnement.

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

e. Ne jamais toucher simultanément les parties sous tensiondes porte-électrodes connectés à deux machines à souderparce que la tension entre les deux pinces peut être letotal de la tension à vide des deux machines.

f. Si on utilise la machine à souder comme une source decourant pour soudage semi-automatique, ces precautionspour le porte-électrode s’applicuent aussi au pistolet desoudage.

2. Dans le cas de travail au dessus du niveau du sol, se protégercontre les chutes dans le cas ou on recoit un choc. Ne jamaisenrouler le câble-électrode autour de n’importe quelle partiedu 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 appropriéainsi qu’un verre blanc afin de se protéger les yeux du ray-onnement de l’arc et des projections quand on soude ouquand on regarde l’arc.

b. Porter des vêtements convenables afin de protéger lapeau de soudeur et des aides contre le rayonnement del‘arc.

c. Protéger l’autre personnel travaillant à proximité ausoudage à l’aide d’écrans appropriés et non-inflammables.

4. Des gouttes de laitier en fusion sont émises de l’arc desoudage. Se protéger avec des vêtements de protection libresde 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 desoudage. Utiliser des lunettes avec écrans lateraux dans les

zones où l’on pique le laitier.

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

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

8. S’assurer que la masse est connectée le plus prés possiblede la zone de travail qu’il est pratique de le faire. Si on placela masse sur la charpente de la construction ou d’autresendroits éloignés de la zone de travail, on augmente le risquede voir passer le courant de soudage par les chaines de lev-age, câbles de grue, ou autres circuits. Cela peut provoquerdes risques d’incendie ou d’echauffement des chaines et descâbles 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 tôlesgalvanisées plombées, ou cadmiées ou tout autre métal quiproduit des fumeés toxiques.

10. Ne pas souder en présence de vapeurs de chlore provenantd’opérations de dégraissage, nettoyage ou pistolage. Lachaleur ou les rayons de l’arc peuvent réagir avec les vapeursdu 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” CSAStandard W 117.2-1974.

PRÉCAUTIONS DE SÛRETÉ POURLES MACHINES À SOUDER ÀTRANSFORMATEUR ET ÀREDRESSEUR

1. Relier à la terre le chassis du poste conformement au code del’électricité et aux recommendations du fabricant. Le dispositifde montage ou la piece à souder doit être branché à unebonne mise à la terre.

2. Autant que possible, I’installation et l’entretien du poste seronteffectués 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 leurplace.

GENERAL DESCRIPTION

The Classic® III and Classic® III D are heavy duty,engine driven, DC arc welding power sources capableof providing constant current output for stick weldingor DC TIG welding. These welders are wound with allcopper coils, rated at 300 amps/32 Volts, and provideother Classic features such as improved door latchesand stainless hinges. With the addition of the optionalK623-1 Wire Feed Module™, the Classic III or ClassicIII D will provide constant voltage output for runningthe LN-7, LN-23P, or LN-25 wire feeders. (The WireFeed Module is factory installed on the K1428-3 andK1433-2).

The Classic III D has Diesel Engine Protection. In theevent of sudden low oil pressure or high coolant tem-perature, the engine immediately shuts down. TheClassic 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 of115/230 volts of 60 cycle AC auxiliary power.

The Classic III unit uses the Continental TM27®industrial water-cooled Gasoline engine, while theClassic III D uses the Continental TMD27® industrialwater-cooled Diesel engine.

DESIGN FEATURES

Control Panel

Both the engine and the welder controls are locatedon one recessed panel at the exciter end of themachine. The welder controls consist of a five step“Current Range Selector” switch and a “Fine CurrentAdjustment” rheostat. Each welder is equipped with a“Start” button, an “Ignition” switch and an “Idler” con-trol switch. The diesel version comes with a “GlowPlug” 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 achoke control (gasoline version only).

All Copper Windings - For long life and dependableoperation.

Engine Idler - Both the Classic III & III D areequipped with an electronic automatic engine idler. Itautomatically increases and decreases engine speedwhen starting and stopping welding or using aux-iliary power. A built-in time delay permits changingelectrodes before the engine slows to its low idlespeed. The “Idler” control switch on the panel locksthe 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 OptionalFeatures for Power Plug Kits.)

Welder Enclosure - The complete welders are rubbermounted on a rugged steel “C” channel base.

The output terminals are placed at the side of themachines so that they are protected by the door. Theoutput 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 thediesel engine down in the event of sudden low oilpressure or high coolant temperature.

PRE-OPERATION INSTALLATION

Exhaust Spark ArresterSome federal, state or local laws may require thatengines be equipped with exhaust spark arresterswhen they are operated in certain locations whereunarrested sparks may present a fire hazard. Thestandard mufflers included with these welders do notqualify as spark arresters. When required by localregulations, suitable spark arresters must be installedand properly maintained.

Use of an incorrect arrester may lead to engine damageor performance loss. Contact the engine manufacturerfor specific recommendations.------------------------------------------------------------------------Location / Ventilation

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

The welder should be located to provide an unrestrict-ed flow of clean, cool air. Also, locate the welder sothat engine exhaust fumes are properly vented to anoutside area.

STACKING

Classic III and III D machines cannot be stacked.

ANGLE OF OPERATION

To achieve optimum engine performance the ClassicIII and III D should be run in a level position. The max-imum angle of operation for the TM27 and TMD27engines is 60 degrees in a direction to cause the airintake manifold to be angled up, 45 degrees for the airintake manifold to be angled down, and 50 degreesfor the welder control panel to be angled up or down.If the engine is to be operated at an angle, provisionsmust be made for checking and maintaining the oillevel at the normal (FULL) oil capacity in thecrankcase. 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 ElectricalCode, the frame of this portable generator is notrequired to be grounded and is permitted to serve asthe grounding means for cord connected equipmentplugged into its receptacle.

Some state, local, or other codes or unusual operatingcircumstances may require the machine frame to begrounded. It is recommended that you determine theextent to which such requirements may apply to yourparticular situation and follow them explicitly. Amachine grounding stud marked with the symbol isprovided on the welding generator frame foot. (If anolder portable welder does not have a grounding stud,connect the ground wire to an unpainted frame screwor bolt.) In general, if the machine is to be grounded,it should be connected with a #8 or larger copper wireto a solid earth ground such as a metal water pipegoing into the ground for at least ten feet and havingno insulated joints, or to the metal framework of abuilding which has been effectively grounded. TheU.S. National Code lists a number of alternate meansof grounding electrical equipment.

Do not attempt to use this equipment until youhave thoroughly read the engine manufacturer’smanual supplied with your welder. It includesimportant safety precautions, detailed enginestarting, operating and maintenance instructions,and parts lists.------------------------------------------------------------------------

ELECTRIC SHOCK can kill.• Do not touch electrically live parts orelectrode with skin or wet clothing.• Insulate yourself from work andground• Always wear dry insulating gloves.

------------------------------------------------------------------------ENGINE EXHAUST can kill.• Use in open, well ventilated areas orvent exhaust outside.

------------------------------------------------------------------------MOVING PARTS can injure.• Do not operate with doors open orguards off.• Stop engine before servicing.• Keep away from moving parts.

Trailer (See Optional Features)

If the user adapts a non-Lincoln trailer, he mustassume responsibility that the method of attachmentand usage does not result in a safety hazard nor dam-age the welding equipment. Some of the factors to beconsidered are as follows:

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

2. Proper support of, and attachment to, the base ofthe welding equipment so there will be no unduestress to the framework.3. Proper placement of the equipment on the trailer toensure stability side to side and front to back whenbeing moved and when standing by itself while beingoperated 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. (1)(1) Consult applicable federal, state and local laws regarding specificrequirements for use on public highways.

Polarity Control and Cable Sizes

With the engine off, route the electrode and workcables through the strain relief bracket on the baseand connect to the studs located below the fuel tankmounting rail. (See size recommendations below.)For positive polarity, connect the electrode cable tothe terminal marked “+”. For Negative polarity, con-nect the electrode cable to the “-” stud.

PRE-OPERATION SERVICE

READ the engine operating and maintenance instruc-tions supplied with this machine.

Oil

This unit is supplied from the factory with the enginecrankcase filled with a high quality SAE 10W/30 oil.This oil should be acceptable for most typical ambienttemperatures. Consult the engine operation manualfor specific engine manufacturer’s recommendations.Upon receipt of the welder, check the engine dipstickto be sure the oil is at the “full” mark. DO NOT overfill.

Fuel

Fill the fuel tank with the grade of fuel recommendedin the Engine Operator’s manual. Make sure fuelvalve on the sediment bowl is in the open position.

Cooling System

The radiator has been filled at the factory with a 50-50mixture of ethylene glycol antifreeze and water.Check the radiator level and add a 50-50 solution asneeded (see engine manual or antifreeze container foralternate antifreeze recommendations).

Battery Charging

The Classic III & Classic III D are each equipped witha wet charged battery. The charging current is auto-matically regulated when the battery is low (after start-ing the engine) to a trickle current when the battery isfully charged.

When replacing, jumping or otherwise connecting thebattery to the battery cables, the proper polarity mustbe observed. This system is NEGATIVE GROUND.

CAUTION

Fuel can cause fire or explosion.-• Stop engine while fueling.• Do not smoke when fueling.• Do not overfill tank.

• Keep sparks and flame away from tank.• Wipe up spilled fuel and allow fumes to clearbefore starting engine.------------------------------------------------------------------------

WARNING

GASES FROM BATTERY can explode.• Keep sparks, flame and cigarettesaway.

BATTERY ACID can burn eyes andskin.• Wear gloves and eye protection andbe careful when boosting, charging orworking near battery.

To prevent EXPLOSION when:a) Installing a new battery - disconnect the

negative cable from the old battery first and connect the negative cable to the new battery last.

b) Connecting a battery charger - remove the battery from the welder by disconnecting the negative cable first, then the positive cable andbattery clamp. When reinstalling, connect the negative cable last.

c) Using a booster - connect the positive lead to the battery first, then connect the negative lead to the ground lead on the base.

To prevent ELECTRICAL DAMAGE when:a) Installing a new battery.b) Using a booster.

1. Turn the Idler control switch to “High”.2. Turn the Ignition control switch to “On”.3. Pull out the choke control.4. Press the Start button.5. If the engine fails to start in 60 seconds, wait 30

seconds before repeating the above procedure.6. 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.

7. As engine warms, slowly return the choke control to the in (off) position.


Do not attempt to use this equipment until youhave thoroughly read the engine manufacturer’smanual supplied with your welder. It includesimportant safety precautions, detailed enginestarting, operating and maintenance instructions,and parts lists.------------------------------------------------------------------------

ELECTRIC SHOCK can kill.• Do not touch electrically live parts orelectrode with skin or wet clothing.• Insulate yourself from work andground• Always wear dry insulating gloves.

------------------------------------------------------------------------ENGINE EXHAUST can kill.• Use in open, well ventilated areas orvent exhaust outside.

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 requirelonger glow plug operation.

Under NO conditions should ether or otherstarting fluids be used in conjunction with theglow 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 tominimize 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 thefuel feed valve beneath the fuel tank. In gasolineengines, failure to turn fuel off when traveling cancause carburetor flooding and difficult starting at thenew job site.

In diesel engines, if the fuel supply is cut off or runsout while the fuel pump is operating, air may beentrapped in the fuel distribution system. If thishappens, bleeding of the fuel system may benecessary. See the Engine Operating Manual.

WELDER OPERATION

Duty Cycle

The NEMA output rating of the Classic III &Classic III D are each 300 amperes at 32 arc volts ona 50% duty cycle (consult Specifications in this manualfor alternate ratings). Duty cycle is based on a tenminute period; thus, the welder can be loaded at ratedoutput 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 mayarc 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 withineach range. Open circuit voltage is also controlled bythe “Fine Current Adjustment” permitting control of thearc 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, setthe “Current Range Selector” to the lowest setting thatstill provides the current you need and set the “FineCurrent Adjustment” near maximum. For example: toobtain 175 amps and a soft arc, set the “Current

Range Selector” to the 190-120 position and thenadjust the “Fine Current Adjustment” for 175 amps.

When a forceful “digging” arc is required, usually forvertical and overhead welding, use a higher “CurrentRange Selector” setting and lower open circuit volt-age. For example: to obtain 175 amps and a forcefularc, set the “Current Range Selector” to the 240-160position and the “Fine Current Adjustment” setting toget 175 amps.

Some arc instability may be experienced with EXX10electrodes when trying to operate with long arc tech-niques at settings at the lower end of the open circuitvoltage 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 whichalmost eliminates the possibility of setting this switchbetween 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 severalminutes to warm the engine. See Specifications foroperating speeds.

The idler is controlled by the “Idler” toggle switch onthe welder control panel. The switch has two posi-tions as follows:

1. In the “High” position, the idler is off, and theengine 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 thereceptacles, the engine operates at full speed.

b. When welding ceases or the power load is turnedoff, a preset time delay of about 15 secondsstarts. This time delay cannot be adjusted.

c. If the welding or power load is not re-startedbefore the end of the time delay, the idler reducesthe 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 orexplosion.• Keep flammable material away.

ARC RAYS can burn.• Wear eye, ear, and body protection.

MAINTENANCE

General Instructions1. Blow out the welder and controls with an air hoseat least once every two months. In particularly dirtylocations, this cleaning may be necessary once aweek. Use low pressure air to avoid driving dirt intothe insulation.

2. ”Current Range Selector” contacts should not begreased. To keep the contacts clean, rotate the cur-rent control through its entire range frequently. Goodpractice is to turn the handle from maximum to mini-mum setting twice each morning before starting toweld.

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 soequipped, from beneath the fuel tank and clean outany accumulated dirt and water.

5. Follow the engine service schedule in this manualand the detailed maintenance and troubleshooting inthe 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 preventloss of coolant. Clean and flush the cooling systemperiodically 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 ballbearing having sufficient grease to last indefinitelyunder 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. Apad of grease one inch wide, one inch long, and oneinch high weighs approximately one half ounce. Over-greasing is far worse than insufficient greasing.

When greasing the bearings, keep all dirt out of thearea. Wipe the fittings completely clean and useclean equipment. More bearing failures are causedby 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 donot catch in the rotating parts. Protect yourselffrom 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, andbrushes by removing the covers. DO NOT remove orreplace these covers while the machine is running.Commutators and slip rings require little attention.However, if they are black or appear uneven, havethem cleaned by an experienced maintenance manusing fine sandpaper or a commutator stone. Neveruse emery cloth or paper for this purpose. NOTE: Ifthe welder is used in dirty or dusty locations, or if thewelder is not used for prolonged periods of time, itmay be necessary to clean the commutator and sliprings more often.


Have qualified personnel do the maintenancework. Turn the engine off before working insidethe machine. In some cases, it may be neces-sary to remove safety guards to performrequired maintenance. Remove guards onlywhen necessary and replace them when themaintenance 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 coolingblower fan. If a problem cannot be corrected byfollowing the instructions, take the machine tothe nearest Lincoln Field Service Shop.

WARNING

WARNING

D-2MAINTENANCED-2

Replace brushes when they wear within 1/4” of thepigtail. A complete set of replacement brushes shouldbe kept on hand. Lincoln brushes have a curved faceto fit the commutator. Have an experienced mainte-nance man seat these brushes by lightly stoning thecommutator as the armature rotates at full speed untilcontact 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 inplace. Then slide one end of a piece of fine sandpa-per between slip rings and brushes with the coarseside against the brushes. With slight additional fingerpressure on top of the brushes, pull the sandpaperaround the circumference of the rings - in direction ofrotation only - until brushes seat properly. In addition,stone slip ring with a fine stone. Brushes must beseated 100%.

Arcing or excessive exciter brush wear indicates apossible misaligned shaft. Have an authorized FieldService Shop check and realign the shaft.

Idler Maintenance

Before doing electrical work on the idler printedcircuit board, disconnect the battery.------------------------------------------------------------------------When installing a new battery or using a jumper bat-tery to start the engine, be sure the battery polarity isconnected properly. The correct polarity is negativeground. Damage to the engine alternator and theprinted circuit board can result from incorrect connec-tion.

1. The solenoid plunger must work freely and notbind. Dust the plunger about once a year withgraphite 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 thismachine - or at least yearly - inspect all nameplatesand labels for legibility. Replace those which are nolonger clear. Refer to the parts list for the replace-ment item number.
