FIRE HAZARDS

WARNING

FIRE OR EXPLOSION CAN CAUSEDEATH, INJURY, AND PROPERTYDAMAGE! To reduce risk of death,

injury, or property damage from fire orexplosion, read, understand, and followthe following safety instructions. Inaddition, make certain that anyone elsethat uses this welding equipment, or is abystander in the welding area,understands and follows these safety

instructions as well. REMEMBER! Arc

welding by nature produces sparks, hotspatter, molten metal drops, hot slag,and hot metal parts that can start fires,burn skin, and damage eyes.

• Do not wear gloves or other clothingthat contain oil, grease, or otherflammable substances.

Do not wear flammable hairpreparations.

Do not weld in an area until it ischecked and cleared of combustibleand/or flammable materials. BE

AWARE that sparks and slag can fly35 feet and can pass through smallcracks and openings. If work andcombustibles cannot be separated bya minimum of 35 feet, protect againstignition with suitable, snug-fitting, fireresistant, covers or shields.

• Do not weld on walls until checking forand removing combustibles touchingthe other side of the walls.

• Do not weld, cut, or perform othersuch work on used barrels, drums,tanks, or other containers that hadcontained a flammable or toxicsubstance. The techniques forremoving flammable substances andvapors, to make a used container safefor welding or cutting, are quitecomplex and require special educationand training.

• Do not strike an arc on a compressedgas or air cylinder or other pressurevessel. Doing so will create a brittlearea that can result in a violent ruptureimmediately or at a later time as aresult of rough handling.

• Do not weld or cut in an area where

the air may contain flammable dust(such as grain dust), gas, or liquidvapors (such as gasoline).

• Do not handle hot metal, such as theworkpiece or electrode stubs, withbare hands.

Wear leather gloves, heavy longsleeve shirt, cuffless trousers, high-topped shoes, helmet, and cap. Asnecessary, use additional protectiveclothing such as leather jacket or

5

sleeves, fire resistant leggings, orapron. Hot sparks or metal can lodgein rolled up sleeves, trouser cuffs, orpockets. Sleeves and collars shouldbe kept buttoned and pocketseliminated from the shirt front.

Have fire extinguishing equipmenthandy for immediate use! A portablechemical fire extinguisher, type ABC,is recommended.

• Wear ear plugs when weldingoverhead to prevent spatter or slagfrom falling into ear.

• Make sure welding area has a good,solid, safe floor, preferably concrete ormasonry, not tiled, carpeted, or madeof any other flammable material.

• Protect flammable walls, ceilings, andfloors with heat resistant covers orshields.

Check welding area to make sure it isfree of sparks, glowing metal or slag,and flames before leaving the weldingarea.

FUME HAZARDS

WARNING

FUMES, GASSES, AND VAPORS CANCAUSE DISCOMFORT, ILLNESS, ANDDEATH! To reduce risk of discomfort,illness, or death, read, understand, and

follow the following safety instructions. Inaddition, make certain that anyone elsethat uses this welding equipment or is abystander in the welding area,understands and follows these safetyinstructions as well.

• Do not weld in an area until it is

checked for adequate ventilation asdescribed in ANSI standard #Z49.1. If

ventilation is not adequate toexchange all fumes and gassesgenerated during the welding processwith fresh air, do not weld unless you(the welder) and all bystanders arewearing air-supplied respirators.

• Do not heat metals coated with, orthat contain, materials that producetoxic fumes (such as galvanized

6

steel), unless the coating is removed.Make certain the area is well

ventilated, and the operator and allbystanders are wearing air-suppliedrespirators.

Do not weld, cut, or heat lead, zinc,cadmium, mercury, beryllium, orsimilar metals without seekingprofessional advice and inspection ofthe ventilation of the welding area.These metals produce EXTREMELYTOXIC fumes which can causediscomfort, illness, and death.

• Do not weld or cut in areas that are

near chlorinated solvents. Vapors fromchlorinated hydrocarbons, such astrichloroethylene andperchloroethylene, can bedecomposed by the heat of an electricarc or its ultraviolet radiation. Theseactions can cause PHOSGENE, aHIGHLY TOXIC gas to form, alongwith other lung and eye-irritatinggasses. Do not weld or cut wherethese solvent vapors can be drawninto the work area or where the

ultraviolet radiation can penetrate toareas containing even very smallamounts of these vapors.

• Do not weld in a confined area unless

it is being ventilated or the operator(and anyone else in the area) iswearing an air-supplied respirator.

• Stop welding if you developmomentary eye, nose, or throatirritation as this indicates inadequateventilation. Stop work and takenecessary steps to improve ventilationin the welding area. Do not resumewelding if physical discomfort persists.

POWER SOURCECONNECTION

WARNING

High voltage danger from powersource! Consult a qualifiedelectrician for proper installation ofreceptacle at the power source.

• This welder must be grounded whilein use to protect the operator fromelectrical shock. If you are not sure ifyour outlet is properly grounded, haveit checked by a qualified electrician.Do not cut off the grounding prong oralter the plug in any way and do notuse any adapters between thewelder's power cord and the powersource receptacle.

Make sure the POWER switch is OFF

then connect your welder's power cordto a properly grounded 120 Vac, 60 Hz,single phase, 15 amp power source. Donot operate this welder if the sourcevoltage is less than 105 Vac or greaterthan 132 Vac. Contact a qualifiedelectrician if this problem exists.Improper performance and/or damage tothe welder will result if operated oninadequate or excessive power.

EXTENSION CORDS

For optimum welder performance, anextension cord should not be used

unless absolutely necessary. Ifnecessary, care must be taken inselecting an extension cord appropriatefor use with your specific welder.

Select a properly grounded extensioncord that will mate directly with the acpower source receptacle and the welderpower cord without the use of adapters.Make certain that the extension cord is

properly wired and in good electricalcondition.

Extension cords must fit the followingwire size guidelines:

• 0-25 ft. requires #12 gauge

• Do not use an extension cord over 25

ft. in length

SELECTING THE WELDINGWIRE

This welder uses only four inch spools of0.030 inch (0.8mm) self shielding flux-core wire, AWS classification numberE71T-GS. Steel from 18 gauge up to3/16 inch thick can be welded with thiswire.

NOTE:

• Metal thinner than 18 gauge cannotbe welded with this machine.Attempting to do so will cause burnthrough (blowing holes) in the metalyou are intending to weld.

• If a spool has developed heavyoxidation, the only solution to theproblem is to discard the spool of wire.

If you have an oxidized spool of wire, donot discard it until you have unspooled afew turns of wire to see if the wire further

down on the spool is in usable condition,if not, - discard the spool.

INSTALL THE WELDINGWIRE

WARNING

Electric shock can kill! Always turn thePOWER switch OFF and unplug thewelder's power cord from the ac powersource before installing wire.

Figure 3. Drive Brake Assembly

Adjust the drive brake tension. Thepurpose of the drive brake is tocause the spool of wire to stopturning at nearly the same momentthat wire feeding stops.

After checking to make sure thatyour welder is disconnected fromthe ac power source, free theleading end of the wire from thespool, but do not let go of it until toldto do so, or the wire will unspoolitself.

Using a wire cutter, cut the bent endoff the leading end of the wire sothat only a straight leading endremains.

Hold the tension arm up off thedrive roller and insert the leadingend of the wire into the inlet guidetube. Then push it across the driveroller and into the gun assemblyabout six inches.

Line the wire up in the outsidegroove of the drive roller, then allowthe drive tension arm to drop ontothe drive roller.

Tighten (turn clockwise) the tensionadjusting screw until the tensionroller is applying enough force onthe wire to prevent it from slippingout of the drive assembly.

13.

Let go of the wire.

Plug the welder's power cord intothe ac power source. Adjust theHEAT selection switches, on thefront of the welder, to any of the fourheat settings.

WARNING

ARC RAYS CAN INJURE EYES!To reduce the risk of arc flash, makecertain that the welding wire, when itfinally comes out of the end of thegun, does not touch the groundclamp or any grounded piece ofmetal. IMPORTANT! The weldingwire is carrying welding currentwhenever the welder is turned on--WHETHER THE TRIGGER ISPULLED OR NOT!

14. Pull the trigger on the welding gunto feed the wire through the gunassembly.

15. When at least an inch of wire sticks

out past the end of the gun, releasethe trigger.

16. Install the supplied 0.030 inch(0.8mm) size contact tip.

17. Slide the contact tip over the wire(protruding from the end of thegun). Screw the contact tip into theend of the gun and hand tightensecurely.

18. Install the nozzle on the gunassembly.

19. Cut off the excess wire that extends

past the end of the nozzle.

20. Set the wire drive tension.

WARNING

ARC RAYS CAN INJURE EYES!To reduce the risk of arc flash, makecertain that the wire coming out ofthe end of the gun does not come incontact with the ground clamp or anygrounded material during the drivetension setting process or arcing willoccur.

a.

b.

Pull the trigger on the gun.

Turn the drive tensionadjustment knob clockwise,increasing the drive tensionuntil the wire seems to feed

smoothly with out slipping.

NOTE: If TOO MUCH tension is

applied, the wire will slip onthe drive roller or will not beable to be fed at all. If TOO

LITTLE tension is applied,the spool of wire will want tounspool itself. Readjust thedrive brake tension as

necessary to correct foreither problem.

c. Block the end of the nozzle byholding it up againstsomething that doesn'tconduct electricity, such as ablock of wood or a concrete

floor, then trigger the gunagain, the wire should slip atthe drive roller. However, if thewire bird-nests at the driveroller, rethread the drivesystem using less drivetension and try again.

When the drive tension is set correctly,there should be no slippage between thewire and the drive roller. But if an

obstruction occurs along the wire feedpath, the wire should then slip on thedrive roller.

OPERATING THE WELDER

DUTY CYCLE

The duty cycle rating of a welder defineshow long the operator can weld and howlong the welder must be rested andcooled. Duty cycle is expressed as apercentage of 10 minutes andrepresents the maximum welding timeallowed. The balance of the 10 minute

cycle is required for cooling.

Your new welder has a duty cycle ratingof 20% at the CSA rated output of 80amps. This means that you can weld fortwo (2) minutes out of 10 with theremaining eight (8) minutes required forcooling. (See the table 3.)

CAUTION

Do not constantly exceed the dutycycle or damage to this welder canresult.

INTERNAL THERMALPROTECTION

If you exceed the duty cycle of yourwelder, the HIGH/LOW switch will

illuminate, an internal thermal protectorwill open and shut off all welderfunctions. After cooling, the thermalprotector will automatically reset and thewelder will function normally again.

CONTROLS AND INDICATORS

WARNING

ELECTRIC SHOCK CAN KILL!To remove the risk of electric shock,be aware that the POWER switch,when OFF, does not remove powerfrom all internal circuitry in thewelder.

The HIGH/LOW RANGE SWITCH

controls the main power to the welderlights up when the dugy cycle has beenexceeded and selects the two main heat

ranges. When the switch is OFF, thereis still power to some areas of thewelder. When working inside the welderor when removing panels on the welder,make sure the welder is unplugged fromthe wall outlet.

12

The MINIMAX SELECTOR allows youto select minimum and maximum heat

settings within the high and low ranges.Refer to the instruction label inside the

welder's hood for suggestions on whichheat setting to use for your welding job.

PREPARATIONS FOR WELDING

An important factor in making asatisfactory weld is preparation. Thisincludes studying the process andequipment and then practice weldingbefore attempting to weld finishedproduct. An organized, safe, convenient,comfortable, well-lighted work areashould be available to the operator. Thework area should specifically be free ofall flammables with both a fire

extinguisher and bucket of sandavailable.

To properly prepare for welding, it isnecessary to:

• Prepare an organized, well lightedwork area (see Figure 4).

• Provide protection for the eyes andskin of the operator and by-bystanders.

• Set up the work piece and make theground clamp connection.

• Select the electrode.

• Adjust the heat control.

WARNING

Exposure to a welding arc isextremely harmful to the eyes andskin. Prolonged exposure to awelding arc can cause blindness andburns. Never strike an arc or beginwelding unless you are adequatelyprotected. Wear flameproof weldinggloves, heavy long sleeved shirt,cuffless trousers, high topped shoesand a welding helmet.

Figure 4. Work Surface andEquipment

SETTING UP THE WORK PIECE

WELDING POSITIONS

Welding with an ac wire welder can bedone in any of three basic positions:Flat, Horizontal, and Vertical. Flatwelding is generally easier, faster andallows for better penetration. The heat(amperage) selections will be affectedby the positions. Vertical welding isusually only attempted when using a dcwelder. If possible, the work pieceshould be positioned so that the beadwill run on a flat surface.

PREPARING THE JOINT

For effective welding, the surfaces to bejoined must be free of dirt, rust, scale, oilor paint. Welding on metals not properlycleaned will cause a brittle and porousweld.

If the base metal pieces to be joined arethick or heavy, it may be necessary tobevel the edges, with a metal grinder, atthe point of contact, as in Figure 5. Theangle of the bevel should beapproximately 60 degrees.

CORRECT

Figure 5. Workpiece Preparation

13

WARNING

To help prevent eye injuries whengrinding, always wear goggles. Thegrinder must also be inspected toverify that it is in good condition.

See the chart, TYPES OF WELDJOINTS, in Figure 6, for detailedinstructions for preparing the weld joint.

During the welding, the work pieces willbecome hot and will tend to expand. Theexpansion may cause the pieces to shiftfrom the regular position. If possible, thework pieces should be clamped into theposition they are to occupy when thewelding is completed.

WARNING

ARC RAYS CAN INJURE EYESAND BURN SKIN! To reduce therisk of injury from arc rays, neverstrike a welding arc until you, and allbystanders in the welding area, havewelding helmet or shield in place andare wearing the recommendedprotective clothing. DO NOTCONTINUE unless you have read,understand and intend to follow the

entire SAFETY SUMMARY providedat the front of this manual.

Ground Clamp Connection

The ground clamp connection is part ofthe current circuit. A poor connection atthe ground clamp will waste power andheat. Scrape away dirt, rust, scale, oil orpaint. Make sure the ground clamptouches the metal.

GET TO KNOW YOURWELDER

Whether you have welded before or not,it is important that you become familiarwith your new welder, its controls, andthe results achieved at different settings.We strongly recommend that youpractice your new welder on scrap metaltrying different heat settings, base metalthicknesses, and welding positions foreach type. By doing this you will gain afeel for how changes in these weldingvariables affect the weld.

The self taught welder learns through aprocess of trial and error. The best wayto teach yourself how to weld is withshort periods of practice at regularintervals. All practice welds should bedone on scrap metal that can bediscarded. Do not attempt to make anyrepairs on valuable equipment until youhave satisfied yourself that your practicewelds are of good appearance and freeof slag or gas inclusions. What you failto learn through practice will be learnedthrough mistakes and re-welds later on.

HOLDING THE GUN

The best way to hold the welding gun isthe way that feels most comfortable toyou. While practicing to use your newwelder, experiment holding the gun indifferent positions until you find the onethat seems to work best for you.

Position The Gun To The Workpiece

There are two angles of the gun nozzlein relation to the work piece that must beconsidered when welding.

1. Angle A (Figure 7) can be varied,but in most cases the optimumangle will be 60 degrees. The pointat which the gun handle is parallelto the work piece. If angle A isincreased, penetration will increase.If angle A is decreased, penetrationwill decrease also.

m m m

Angle AFigure 7. Gun Position, Angle A

. Angle B (Figure 8) can be varied fortwo reasons: to improve the abilityto see the arc in relation to the weld

puddle and to direct the force of thearc.

The force of the welding arc follows astraight line out of the end of the nozzle.If angle B is changed, so will thedirection of arc force and the point atwhich penetration will be concentrated.

On a butt weld joint, the only reason tovary angle B from perpendicular(straight up) to the work piece would beto improve visibility of the weld puddle.In this case, angle B can be variedanywhere from zero to 45 degrees with30 degrees working about the best.

On a fillet weld joint, the nozzle isgenerally positioned in such a mannerso as to split the angle between thehorizontal and vertical members of the

weld joint. In most cases, a fillet weldwill be 45 degrees.

Distance From The Workpiece

The end of the welding gun is designedwith the contact tip recessed from theend of the nozzle and the nozzle

electrically insulated from the rest of thegun. This permits the operator toactually rest the nozzle on the workpiece and drag it along while welding.This can be very helpful to beginningwelders to steady the gun, allowing thewelder to concentrate on weldingtechnique. If the nozzle is held off thework piece, the distance between thenozzle and the work piece should be 1/4inch to 3/8 inch depending on the gaugeof the metal and the amount of

penetration desired. Moving closer to theworkpiece increases penetration.Moving away from the workpiecedecreases penetration. The correctdistance must still be maintained, or thearc may begin sputtering, signaling aloss in welding performance.

LAYING A BEAD

WARNING

EXPOSURE TO A WELDING ARCIS EXTREMELY HARMFUL TO THE

EYES AND SKIN! Prolongedexposure to the welding arc cancause blindness and burns. Never

strike an arc or begin welding untilyou are adequately protected. Wearflameproof welding gloves, A heavylong sleeved shirt, cuffless trousers,high topped shoes and a weldinghelmet.

WARNING

ELECTRIC SHOCK CAN KILL! To

prevent ELECTRIC SHOCK, do notperform any welding while standing,kneeling, or lying directly on thegrounded work.

TYPES OF WELD BEADS

The following paragraphs discuss themost commonly used arc weldingbeads.

IMPORTANT! The wire in this welder is

always electrically energized wheneverthe power is ON and will arc wheneverbrought into contact with any electricallyconductive materials that the groundclamp of the welder is connected to orwith which it is in contact. Therefore, it isbest to clip the wire back to the contacttip so that you don't create an arc whenlining up on the seam to be welded.

Once you have the gun in position withthe wire lined up on the weld joint, coveryour face with the face shield, pull thetrigger and the arc will start. In a secondor two you will notice a weld puddle formand the base of the bead beginning tobuild. It is now time to begin to travelwith the gun. If you are just learning toweld, travel by simply dragging the gunin a straight line and at a steady speedalong the weld joint. Try to achieve aweld with the desired penetration and abead that is fairly flat and consistent inwidth.

16

As you become more familiar with yournew welder and better at laying somesimple weld beads, you can begin to trysome different welding techniques toimprove, and add versatility to yourwelding skills.

TRAVELING THE GUNGun travel refers to the movement of the

gun along the weld joint and is brokeninto two elements: Direction and Speed.A solid weld bead requires that thewelding gun be moved steadily and atthe right speed along the weld joint.Moving the gun too fast, too slow, orerratically will prevent proper fusion orcreate a lumpy, uneven bead.

1. TRAVEL DIRECTION is the

direction the gun is moved alongthe weld joint in relation to the weldpuddle. The gun is either PUSHED(see Figure 9) into the weld puddleor PULLED away from the weldpuddle.

Figure 9. Gun Travel Direction

For most welding jobs you will pull thegun along the weld joint to takeadvantage of the greater weld puddlevisibility. However, there are a fewapplications where pushing the gun mayprovide some advantages:

VERTICAL WELDING can be done bystarting at the top of a weld joint andpulling the gun down toward the bottom.However, in the event that puddlecontrol becomes difficult (such as thepuddle wanting to run downward),starting a vertical weld at the bottom of aweld joint and pushing the gun uptoward the top will help to overcome thisproblem.

2. TRAVEL SPEED is the rate at which

the gun is being pushed or pulledalong the weld joint. For a fixedheat setting, the faster the travelspeed, the lower the penetrationand the lower and narrower the

finished weld bead. Likewise, theslower the travel speed, the deeperthe penetration and the higher andwider the finished weld bead.

TYPES OF WELD BEADS

, The STRINGER BEAD (Figure 10)is formed by traveling with the gunin a straight line while keeping thewire and nozzle centered over the

weld joint. This is the easiest type ofbead to make and is the type youhave been using up to this point.

,

Figure 10. Stringer Weld Bead

The WEAVE BEAD (Figure 11)isused when you want to depositmetal over a wider space thanwould be possible with a stringerbead. It is made by weaving fromside to side while traveling with thegun. It is best to hesitatemomentarily at each side beforeweaving back the other way.

Figure 11. Weave Weld Bead

17

WELDING POSITIONS

There are three basic welding positions:flat, horizontal, and vertical.

. The FLAT POSITION (Figure 12) isthe easiest of the welding positionsand is probably the one you havebeen using thus far. It is best if youcan weld in the flat position if at allpossible as good results are easierto achieve.

.

Figure 12. Flat Position Weld

The HORIZONTAL POSITION

(Figure 13) is next in difficulty level.It is performed very much the sameas the flat weld except that angle B(see POSITION OF THE GUN TOTHE WORK PIECE, above) is suchthat the wire, and therefore the arcforce, is directed more toward themetal above the weld joint. This isto help prevent the weld puddlefrom running downward while stillallowing slow enough travel speedto achieve good penetration. A goodstarting point for angle B is about30 degrees DOWN from beingperpendicular to the work piece.

Figure 13. Horizontal Position Weld

. The VERTICAL POSITION (Figure14) is the next most difficultposition. Pulling the gun from top tobottom may be easier for manypeople, but in some instances it canbe difficult to prevent the puddlefrom running downward. Pushingthe gun from bottom to top mayprovide better puddle control andallow slower rates of travel speed toachieve deeper penetration. Whenvertical welding, angle B (seePOSITION OF GUN TO THE

WORK PIECE, above) is usuallyalways kept at zero, but angle A willgenerally range from 45 to 60degrees to provide better puddlecontrol.

Figure 14. Vertical Position Weld

MULTIPLE PASS WELDINGButt Weld Joints. In PREPARING THE

WORK PIECE, we discussed the needfor edge preparation on thicker materialsby grinding a bevel on the edge of oneor both pieces of the metal being joined.When this is done, a V is created,between the two pieces of metal, thatwill have to be welded closed. In most

cases more than one pass or bead willneed to be rayed into the joint to closethe V. Laying more than one bead intothe same weld joint is known as amultiple-pass weld.

NOTE: WHEN USING SELF-SHIELDING FLUX-CORE

WIRE it is very important tothoroughly chip and brushthe slag off each completedweld bead before makinganother pass or the nextpass will be of poor quality.

The illustrations in Figure 15 show thesequence for laying multiple pass beadsinto a single V butt joint.

Most fillet weld joints, on metals ofmoderate to heavy thickness, will requiremultiple pass welds to produce a strongjoint. The illustrations in Figure 16 showthe sequence of laying multiple passbeads into a T fillet joint and a lap filletjoint.

SPECIAL WELDINGMETHODS

SPOT WELDING

The purpose of a spot weld is to joinpieces of metal together with a spot ofweld instead of a continuous weld bead.

There are three methods of spotwelding: Burn-Through, Punch and Fill,and Lap (see Figure 17). Each hasadvantages and disadvantagesdepending on the specific application aswell as personal preference.

PUNCHANDFILL

BURNTHROUGH

LAPSPOT

Figure 17. Spot Weld Methods

1. The BURN-THROUGH METHOD

welds two overlapped pieces ofmetal together by burning throughthe top piece and into the bottompiece.

0.030 inch self-shielding flux-core wireshould not be used with the burn-

through method unless the metal is

19

VERY thin or excessive filler metal

build-up and minimal penetration isacceptable•

Always select the HIGH heat setting withthe burn-through method prior to makinga spot weld.

2• The PUNCH AND FILL METHOD

produces a weld with the mostfinished appearance of the threespot weld methods. In this method,a hole is punched or drilled into thetop piece of metal and the arc isdirected through this hole topenetrate into the bottom piece.The puddle is allowed to fill up thehole leaving a spot weld that issmooth and flush with the surface of

the top piece.

Select the, heat setting, as if you werewelding the same thickness materialwith a continuous bead.

3. The LAP SPOT METHOD directs

the welding arc to penetrate thebottom and top pieces, at the sametime, right along each side of thelap joint seam.

Select the heat setting as if you werewelding the same thickness materialwith a continuous bead.

SPOT WELDING INSTRUCTIONS

• Select the heat settingrecommended above for the

method of spot welding you intendto use.

.

.

Hold the nozzle piece completelyperpendicular to and about 1/4 inchoff the work piece•

Pull the trigger on the gun andrelease it when it appears that thedesired penetration has beenachieved.

.

.

Make practice spot welds on scrapmetal, varying the length of timeyou hold the trigger, until a desiredspot weld is made.

Make spot welds on the actual workpiece at desired locations.

GENERAL MAINTENANCE

This welder has been engineered to givemany years of trouble-free serviceproviding that a few very simple stepsare taken to properly maintain it.

1. Keep the wire drive compartment lidclosed at all times unless the wire

needs to be changed or the drivetension needs adjusting.

2. Keep all consumables (contact tips,nozzles, and gun liner) clean andreplace when necessary. SeeCONSUMABLE MAINTENANCEAND TROUBLESHOOTING later inthis section for detailed information.

.

.

Replace power cord, ground cable,ground clamp, or gun assemblywhen damaged or worn.

Periodically clean dust, dirt, grease,etc. from your welder. Every sixmonths or as necessary, removethe side panels from the welder andair-blow any dust and dirt that mayhave accumulated inside thewelder.

WARNING

ELECTRIC SHOCK CAN KILL! Toreduce the risk of electric shock,always unplug the welder from its acpower source before removing sidepanels.

MAINTENANCE AND CLEANING

IT IS VERY IMPORTANT TO MAINTAIN

THE CONSUMABLES TO AVOID THENEED FOR PREMATURE

REPLACEMENT OF THE GUN

ASSEMBLY.

CAUTION

KEEP THE NOZZLE CLEAN!

During the welding process, spatterand slag will build up inside thenozzle and must be cleaned out

periodically. Failure to clean and/or

replace the nozzle in a timelyfashion WILL CAUSE DAMAGE TO

THE FRONT-END OF THE GUN

ASSEMBLY, which is NOTREPLACEABLE. The results of the

inaction will REQUIRE THEREPLACEMENT OF THE ENTIRE

GUN ASSEMBLY.

1. Stop welding and clean anyaccumulated slag or spatter fromthe nozzle every 5 to 10 minutes ofwelding time.

2. When welding overhead, if anymolten metal drips from the weldpuddle and falls into the nozzle,STOP WELDING IMMEDIATELYand clean the nozzle.

. If the slag cannot be thoroughlycleaned from the nozzle, REPLACETHE NOZZLE!

Failure to keep the nozzle adequatelycleaned can result in the followingproblems:

A SHORTED nozzle results when

spatter buildup bridges the insulation inthe nozzle allowing welding current toflow through it as well as the contact tip.When shorted, a nozzle will steal

welding current from the wire wheneverit contacts the grounded work piece.This causes erratic welds and reduced

penetration. In addition, a shorted nozzleoverheats the end of the gun which canDAMAGE the front-end of the gun.

TESTING FOR A SHORTEDNOZZLE

Arcing between the nozzle and the workpiece ALWAYS means the nozzle isshorted, but this can be hard to detectthrough the lens of a welding helmet.The following testing method is anotherway to tell if a nozzle is shorted.

With the welder unplugged from the acpower source, touch the probes of anohmmeter or continuity tester to the endof the contact tip and the outside of the

21

nozzle. If there is any continuity at all,the nozzle IS shorted. Clean or replaceas needed.

The following paragraphs describe theprocedures required to maintain andtroubleshoot your welder.

MAINTAINING THEWELDER

Except for internal and externalcleaning, cleaning the nozzle, andoccasionally retightening screws, thereis no periodic maintenancerecommended for your welder.
