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.

Diesel engine exhaust and some of its constituentsare known to the State of California to cause can-cer, birth defects, and other reproductive harm.

The engine exhaust from this product containschemicals known to the State of California to causecancer, birth defects, or other reproductive harm.

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 to form 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 instruc-tions et les précautions de sûreté specifiques qui parraissentdans ce manuel aussi bien que les précautions de sûretégénérales suivantes:

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 unegrande partie du corps peut être en contact avec lamasse.

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 soud-er parce 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 pro-téger contre les chutes dans le cas ou on recoit un choc. Nejamais enrouler le câble-électrode autour de n’importe quellepartie 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 appropriéainsi qu’un verre blanc afin de se protéger les yeux durayonnement de l’arc et des projections quand on soudeou quand 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-inflamma-bles.

4. Des gouttes de laitier en fusion sont émises de l’arc desoudage. Se protéger avec des vêtements de protectionlibres de l’huile, tels que les gants en cuir, chemise épaisse,pantalons sans revers, et chaussures montantes.

5. Toujours porter des lunettes de sécurité dans la zone desoudage. Utiliser des lunettes avec écrans lateraux dans leszones 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 lesvapeurs du solvant pour produire du phosgéne (gas forte-ment 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 codede l’électricité et aux recommendations du fabricant. Le dis-positif de montage ou la piece à souder doit être branché àune bonne mise à la terre.

2. Autant que possible, I’installation et l’entretien du posteseront effectués par un électricien qualifié.

3. Avant de faires des travaux à l’ interieur de poste, ladebrancher à l’interrupteur à la boite de fusibles.

4. Garder tous les couvercles et dispositifs de sûreté à leurplace.

5. Carefully detach the end of the wire from the spoolmaintain tension on the wire. To prevent the spoolfrom unwinding and do not release the wire untilafter step 5.

6. Cut the bent portion of wire off and straighten thefirst 4” (100 mm).

7. Thread the wire through the ingoing guide tube,over the drive roll, and into the gun liner.

8. Close the idle roll arm and turn down the thumb-screw until the idle roller presses down firmly on thewire. (Now you may release the welding wire).Make sure the wire is positioned in the groove ofthe lower drive roll.

9. The spring loaded thumbscrew on the idle roll armadjusts the pressure on the wire. Adjust pressureby turning the thumbscrew to prevent spool over-run, but still allow smooth and easy wire feeding.Start with the pressure set to an intermediate value.Readjust, if necessary. Slightly less pressure maybe required when using 0.023 - 0.025” (0.6 mm)wire. If the drive roll slips while feeding wire, thepressure should be increased until the wire feedsproperly.

• When feeding the welding wirethrough the gun, the drive roll, thegun connector block and the guncontact tip are always energized rela-tive to work and ground.

LEARNING TO WELD

No one can learn to weld simply by reading aboutit. Skill comes only with practice. The followingpages will help the operator to understand weldingand develop this skill.

THE ARC-WELDING CIRCUIT

The operator’s knowledge of arc welding must gobeyond the arc itself. The operator must know how tocontrol the arc, and this requires a knowledge of thewelding circuit and the equipment that provides theelectric current used in the arc. Figure B.5 illustratesthe welding circuit for a typical welding machine. Thecircuit begins where the gun cable is attached to thewelding machine. Current flows through the guncable, gun, and contact tip, to the wire and across thearc. On the work side of the arc, current flows throughthe base metal to the work cable and back to thewelding machine. This circuit must be complete for thecurrent to flow.

This machine’s welding circuit has a voltage output of29 volts DC maximum. This voltage is quite low and isonly present when the gun trigger is depressed.

To weld, the work clamp must be tightly connected toclean base metal. Remove paint, rust, dirt or oil asnecessary and connect the work clamp as close aspossible to the area you wish to weld. This helps pre-vent current from going through an unwanted path.Avoid allowing the welding circuit to pass throughhinges, bearings, electronic components, or similardevices that can be damaged. See Figure B.6. Alwaysdisconnect electrical devices before welding uponthem.

FIGURE B.6

Fumes and slag generated fromInnershield type electrodes recom-mended for use with this weldingmachine can be toxic.

• Avoid contact with eyes and skin.

• Do not take internally.

• Keep out of reach of children.

• Follow all safety precautionsfound in this operating manual.

The gun and cable assembly is held by the operatorwho guides the automatically fed wire along the joint,maintaining a contact tip to work distance of about 3/8to 1/2 inch (10 – 12 mm) This is called electrical stick-out. This electrical stickout (ESO) must be properlymaintained by the operator. The electric arc is madein the gap between the work and the tip end of a smalldiameter wire. When the power source is properly set,the arc gap is maintained automatically.

Arc welding is a manual skill requiring a steady hand,good physical condition, and good eyesight. The oper-ator controls the welding arc, and, therefore, the quali-ty of the weld made.

THE SELF-SHIELDED FCAW (FLUXCORE) WELDING ARC

Figure B.7 illustrates the action taking place in the selfshielded FCAW (Innershield) welding arc. It closelyresembles what is actually seen while welding.

Weld Metal

B-7OPERATIONB-7

The “arc stream” is seen in the middle of the picture.This is the electric arc created by the electric currentflowing through the space between the end of the wireelectrode and the base metal. The temperature of thisarc is about 6000°F, which is more than enough tomelt metal. The arc is very bright, as well as hot, andcannot be looked at with the naked eye without riskingpainful injury. The very dark lens, specif icallydesigned for arc welding must be used with the handor face shield whenever viewing the arc.

The arc melts the base metal and actually digs into itmuch as water through a nozzle on a garden hosedigs into the earth. The molten metal forms a moltenpool or crater and tends to flow away from the arc. Asit moves away from the arc, it cools and solidifies.

The function of the Innershield cored wire electrode ismuch more than simply to carry current to the arc. Thewire core is composed of fluxes and/or alloying ingre-dients around which a steel sheath has been formed.It is simply a stick electrode turned inside out in a con-tinuous wire form.

The cored wire melts in the arc and tiny droplets ofmolten metal shoot across the arc into the moltenpool. The wire sheath provides additional filler metalfor the joint to fill the groove or gap between the twopieces of base metal.

The core materials also melt or burn in the arc andperform several functions. They make the arc stead-ier, provide a shield of smoke-like gas around the arcto keep oxygen and nitrogen in the air away from themolten metal, and provide a flux for the molten pool.The flux picks up impurities and forms the protectiveslag on top of the weld during cooling.

After running a weld bead, the slag may be removedwith a chipping hammer and wire brush. Thisimproves appearance and allows for inspection of thefinished weld.

Since machine size and output characteristics limit thesize and type of wire electrode which can be used,Lincoln 0.035’ (0.9 mm) NR-211-MP Innershield elec-trode is recommended for Self-Shielded Flux CoredArc Welding.

THE GMAW (MIG) WELDING ARC

Figure B.8 illustrates the GMAW (MIG) welding arc.Solid wire does not contain fluxes or ingredients toform its own shielding and no slag forms to protect themolten weld metal. For this reason, a continuous evenflow of shielding gas is needed to protect the moltenweld metal from atmospheric contaminants such asoxygen and nitrogen. Shielding gas is suppliedthrough the gun and cable assembly, through the gasnozzle and into the welding zone.

When comparing the GMAW and FCAW processes,you can see that the principal difference between thetwo lies in the type of shielding used. GMAW uses gasfor shielding, thus we have Gas Metal Arc Welding.FCAW uses the melting or burning of the core ingredi-ents for shielding, and is thus termed Self-ShieldedFlux Cored Arc Welding.

The recommended wire for Gas Metal Arc Welding(MIG) is Lincolnweld 0.025” (0.6 mm) L-56 electrode.Lincolnweld” L-56 is capable of welding a wide rangeof mild steels in all positions, however, more skill ISrequired for out-of-position welding with the GMAWprocess.

PROCESS SELECTION

By gaining knowledge of the differences between thetwo processes, you will be able to select the bestprocess for the job you have at hand. In selecting aprocess, you should consider:

For GMAW (MIG) Process1. Is most of my welding performed on 16 gauge and

lighter materials?

2. Can I afford the extra expense, space, and lack ofportability required for gas cylinders and gas sup-ply?

3. Do I require clean, finished-looking welds?

If you have answered yes to all the above questionsGMAW may be the process for you. If you haveanswered no to any of the above questions, then youshould consider using the FCAW process.

For FCAW (Innershield) Process1. Do I want simplicity and portability?

2. Will welding be performed outdoors or under windyconditions?

3. Do I require good all position welding capability?

4. Will most welding be performed on 16 gauge andheavier, somewhat rusty or dirty materials?

5. Weld must be cleaned prior to painting.

COMMON METALS

Most metals found around the farm, small shop orhome are low carbon steel, sometimes referred to asmild steel. Typical items made with this type of steelinclude most sheet metal, plate, pipe and rolledshapes such as channels and angle irons. This type ofsteel can usually be easily welded without special pre-cautions. Some steels, however, contain higher car-bon levels or other alloys and are more difficult toweld. Basically, if a magnet sticks to the metal andyou can easily cut the metal with a file, chances aregood that the metal is mild steel and that you will beable to weld the material.

Regardless of the type of metal being welded, in orderto get a quality weld, it is important that the metal isfree of oil, paint, rust or other contaminants.

JOINT TYPES AND POSITIONS

Five types of welding joints are: Butt Welds, FilletWelds, Lap Welds, Edge Welds and Corner Welds.See Figure B.9.

Of these, the Butt Weld and Fillet Weld are the twomost common welds.

FIGURE B.9

Butt WeldsPlace two plates side by side, leaving a space approx-imately one half the thickness of the metal betweenthem in order to get deeper penetration.

Securely clamp or tack weld the plates at both ends,otherwise the heat will cause the plates to move apart.See Figure B.10.

Now weld the two plates together. Weld from left toright (if right handed). Point the wire electrode down inthe crack between the two plates, keeping the gunslightly tilted in the direction of travel. Watch themolten metal to be sure it distributes itself evenly onboth edges and in between the plates. This is referredto as the “pull technique”. On thin gauge sheet metal,use the “push technique”. See “Welding Techniquesfor GMAW (MIG) Process”.

HANDY MIG

PenetrationUnless a weld penetrates close to 100% of the metalthickness, a butt weld will be weaker than the materialwelded together. In the example shown in FigureB.11, the total weld is only half the thickness of thematerial thus the weld is only approximately half asstrong as the metal.

FIGURE B.11

In the example shown in Figure B.12, the joint hasbeen welded so that 100% penetration could beachieved. The weld, if properly made, is as strong asor stronger than the original metal.

FIGURE B.12

Fillet WeldsWhen welding fillet welds, it is very important to holdthe wire electrode at a 45° angle between the twosides or the metal will not distribute itself evenly. Thegun nozzle is generally formed at an angle to facilitatethis. See Figure B.13.

FIGURE B.13

Welding In The Vertical Position

Welding in the vertical position can be done either ver-tical-up or vertical-down. Vertical-up is used whenevera larger, stronger weld is desired. Vertical-down isused primarily on sheet metal 5/32” (3.9 mm) andunder for fast, low penetrating welds.

Use of this unit on thicker materials than recom-mended may result in poor welds. The welds may“look” good, but may just be “sitting” on top, ofthe plate. This is called “Cold Casting” and willresult in weld failure.

Vertical-up And Overhead WeldingThe problem, when welding vertical-up, is to put themolten metal where it is wanted and make it staythere. If too much molten metal is deposited, gravitywill pull it downwards and make it “drip”. Therefore, acertain technique has to be followed.

When welding out-of-position, run stringer beads.Don’t whip, break the arc, move out of the puddle, ormove too fast in any direction. Use Wire Feed Speed(WFS) in the low portion of the range. The generaltechnique and proper gun angle is illustrated in FigureB.14.

Generally, keep the electrode nearly perpendicular tothe joint as illustrated. The maximum angle above per-pendicular may be required if porosity becomes aproblem.

B-10OPERATIONB-10

HANDY MIG

FIGURE B.14

Vertical-down WeldingRefer to Figure B.15 Vertical-down welds are appliedat a fast pace. These welds are therefore shallow andnarrow and, as such, are excellent for sheet metal.Vertical-down welds may be applied to 5/32” (3.9 mm)and lighter material.

Use stringer beads and tip the gun in the direction oftravel so the arc force helps hold the molten metal inthe joint. Move as fast as possible consistent withdesired bead shape.

The important thing is to continue lowering the entirearm as the weld is made so the angle of the gun doesnot change. Move the electrode wire fast enough thatthe slag does not catch up with the arc. Vertical-downwelding gives thin, shallow welds. It should not beused on heavy material where large welds arerequired.

ARC RAYS can burn eyes and skin.

When using an open arc process, itIs necessary to use correct eye,head and body protection.

Protect yourself and others, read“ARC RAYS can burn” at the frontof this manual.

2. The Correct Way To Strike An Arc1. Be sure the work clamp makes good electrical

contact to the work.

2. Position gun over joint. End of wire may belightly touching the work.

3. Position face shield to protect face and eyes,close gun trigger, and begin welding. Hold thegun so that the contact tip to work distance isabout 3/8 to 1/2 inch (10 – 12 mm).

4. To stop welding, release the gun trigger andthe pull the gun away from the work after thearc goes out.

5. A ball may form at the tip end of the wire afterwelding. For easier restrikes (with Innershieldwire) the ball may be removed by feeding out afew inches of wire and simply bending the wireback and forth until it breaks off.

6. When no more welding is to be done, turn offthe machine.

3. The Correct Electrical Stickout (ESO)The electrical stickout (ESO) is the distance fromthe end of the contact tip to the end of the wire.

See Figure B.17

Once the arc has been established, maintainingthe correct ESO becomes extremely important.The ESO should be approximately 3/8”(10mm)long.

The easiest way to tell whether the ESO is the cor-rect length is by listening to its sound. The correctESO has a distinctive “crackling” sound, very muchlike eggs frying in a pan. A long ESO has a hollow,blowing or hissing sound. If the ESO is too short,you may stick the contact tip or nozzle to the weldpuddle and/or fuse the wire to the contact tip.

4. The Correct Welding SpeedThe important thing to watch while welding is thepuddle of molten metal right behind the arc. SeeFigure B.18. Do not watch the arc itself. It is theappearance of the puddle and the ridge where themolten puddle solidifies that indicates correct weld-ing speed. The ridge should be approximately 3/8”(10 mm) behind the wire electrode.

Most beginners tend to weld too fast, resulting in athin uneven, “wormy” looking bead. They are notwatching the molten metal.

Helpful Hints

1. For general welding, it is not necessary to weavethe arc, neither forward or backward nor sideways.Weld along at a steady pace. You will find it easier.

2. When welding on thin plate, you will find that youwill have to increase the welding speed, whereaswhen welding on heavy plate, it is necessary to gomore slowly in order to get good penetration.

3. When welding sheet metal 16 gauge (1.5 mm) andlighter, heat buildup may cause part warpage andburn through. One way to eliminate these problemsis to use the back-stepping method illustrated inFigure B.19.

FIGURE B.19

Practice

The best way of getting practice in the four skills thatenable you to maintain:

1. Correct welding position

2. Correct way to strike an arc

3. Correct electrical stickout

4. Correct welding speed

is to perform the following exercise.


1. Learn to strike an arc by positioning the gun overthe joint and touching the wire to the work.

2. Position face shield to protect face and eyes.

3. Depress gun trigger, hold gun so contact tip towork distance is about 3/8 to 1/2 inch (10 to 12mm) and the gun is at proper angle.

4. After you strike the arc, practice the correct electri-cal stickout. Learn to distinguish it by its sound.

5. When you are sure that you can hold the correctelectrical stickout, with a smooth “crackling” arcstart moving. Look at the molten puddle constantly,and look at the “ridge” where the metal solidifies.

6. Run beads on a flat plate. Run them parallel to thetop edge (the edge farthest away from you). Thisgives you practice in running straight welds, andalso gives you an easy way to check yourprogress. The 10th weld will look considerably bet-ter than the first weld. By constantly checking onyour mistakes and your progress, welding will soonbe a matter of routine.

First weld from A to B; then from C to A; thenfrom D to C; then from E to D, and so on.

4. To stop welding, release the gun trigger and pullthe gun away from the work after the arc goes out.

5. A ball may form at the tip end of the wire afterwelding. For easier restrikes, the ball may beremoved by feeding out a few inches of wire andcutting off the end of the wire with wire cutters.

Proper Gun Handling

Most feeding problems are caused by improper han-dling of the gun cable or electrodes.

1. Do not kink or pull the gun around sharp corners

2. Keep the gun cable as straight as practical whenwelding.

3. Do not allow dolly wheels or trucks to run over thecables.

4. Keep the cable clean.

5. Innershield electrode has proper surface lubrica-tion. Use only clean, rust-free electrode.

6. Replace contact tip when it becomes worn or theend is fused or deformed.

MAINTENANCE

SAFETY PRECAUTIONS

ELECTRIC SHOCK can kill.

• Disconnect input power by removingplug from receptacle before workinginside machine. Use only groundedreceptacle. Do not touch electrically“hot” parts inside machine

• Have qualified personnel do the mainte-nance and trouble shooting work.

ITEMS REQUIRINGNO MAINTENANCE

• Drive Motor and Gearbox – Lifetime lubrication

• Wire Reel Spindle – Do NOT lubricate shaft

ROUTINE AND PERIODICMAINTENANCE

BEFORE EACH USE

• Check over machine and accessories for any obvious condi-tion that may prevent safe performance or operation. Repairor replace items as necessary to correct any abnormal con-dition.

AFTER 5 MINUTES OF WELDING

or when spatter accumulates in the gas nozzle:

• Clean the contact tip and gas nozzle to avoid bridgingbetween the nozzle and contact tip. Bridging results in ashorted nozzle, poor welds and overheated gun. Hint: Anti-stick spray or gel available from a welding supply distributormay reduce buildup and aid in spatter removal.

CLEANING THE GUN LINER

• Unplug the machine or turn the power switch to theOFF - “0” position.

• Remove the gas nozzle and contact tip from thegun.

• Clean the inside diameter with a short piece of wire.

• Clean the cable liner when rough and erratic wirefeeding occur:

Lay the cable out straight. Blow out gently with drycompressed air (max 145 psi) through the wire guidetube and check the condition of the tube. Bend thecable back and forth, then blow the tube out again.Repeat until clean.

Excessive pressure at start may cause the dirt toform a plug.------------------------------------------------------------------------CLEANING COMPONENTS AS REQUIRED

• Unplug the machine or turn the power switch to theOFF - “0” position.

• Blow dirt out of the welder with low pressure air toeliminate excessive dirt and dust buildup that couldcause the welder to run hot.

• Vacuum accumulated dirt from the gear-box andwire feed section.

• Inspect the incoming guide tube and clean theinside diameter if necessary. Replace when exces-sively worn.

• Replace Contact Tip - when the hole is enlarged orelongated. (Refer to Changing The Contact Tip, inthis section.)

• Check the condition of the wire feed rollers.Remove any metallic dust deposited in the feedarea (rollers and entrance and outlet wire guide).

• Check the gas hose and fittings for tightness.
