SAFETY

WARNING

ARC WELDING can be hazardous.

PROTECT YOURSELF AND OTHERS FROM POSSIBLE SERIOUS INJURY OR DEATH. KEEP CHILDREN AWAY. PACEMAKER WEARERS SHOULD CONSULT WITH THEIR DOCTOR BEFORE OPERATING.

Read and understand the following safety highlights. For additional safety information, it is strongly recommended that you purchase a copy of “Safety in Welding & Cutting - ANSI Standard Z49.1” from the American Welding Society, P.O. Box 351040, Miami, Florida 33135 or CSA Standard W117.2-1974. A Free copy of “Arc Welding Safety” booklet E205 is available from the Lincoln Electric Company, 22801 St. Clair Avenue, Cleveland, Ohio 44117-1199.

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

ELECTRIC SHOCK can kill.

1.a. The electrode and work (or ground) circuits are electrically “hot” when the welder is on. Do not touch these “hot” parts with your bare skin or wet clothing. Wear dry, hole-free gloves to insulate hands.

1.b. Insulate yourself from work and ground using dry insulation. Make certain the insulation is large enough to cover your full area of physical contact with work and ground.

In addition to the normal safety precautions, if welding must be performed under electrically hazardous conditions (in damp locations or while wearing wet clothing; on metal structures such as floors, gratings or scaffolds; when in cramped positions such as sitting, kneeling or Iying, if there is a high risk of unavoidable or accidental contact with the workpiece or ground) use the following equipment:

• Semiautomatic DC Constant Voltage (Wire) Welder.

• DC Manual (Stick) Welder.

• AC Welder with Reduced Voltage Control.

1.c. In semiautomatic or automatic wire welding, the electrode, electrode reel, welding head, nozzle or semiautomatic welding gun are also electrically “hot”.

1.d. Always be sure the work cable makes a good electrical connection with the metal being welded. The connection should be as close as possible to the area being welded.

1.e. Ground the work or metal to be welded to a good electrical (earth) ground.

2.b. Use suitable clothing made from durable flame-resistant material to protect your skin and that of your helpers from the arc rays.

2.c. Protect other nearby personnel with suitable, non-flammable screening and/or warn them not to watch the arc nor expose themselves to the arc rays or to hot spatter or metal.

fumes and gases away from the breathing zone. When

welding with electrodes which require special ventilation such as stainless or hard facing (see instructions on container or MSDS) or on lead or cadmium plated steel and other metals or coatings which produce highly toxic fumes, keep exposure as low as possible and below Threshold Limit Values (TLV) using local exhaust or mechanical ventilation. In confined spaces or in some circumstances, outdoors, a respirator may be required. Additional precautions are also required when welding on galvanized steel.

ARC RAYS can burn.

2.a. Use a shield with the proper filter and cover plates to protect your eyes from sparks and the rays of the arc when welding or observing open arc welding. Headshield and filter lens should conform to ANSI Z87. I standards.

FUMES AND GASES can be dangerous.

3.a. Welding may produce fumes and gases hazardous to health. Avoid breathing these fumes and gases.When welding, keep your head out of the fume. Use enough ventilation and/or exhaust at the arc to keep

1.f.

Maintain the electrode holder, work clamp, welding cable and welding machine in good, safe operating condition. Replace damaged insulation.

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

1.h. Never simultaneously touch electrically “hot” parts of electrode holders connected to two welders because voltage between the two can be the total of the open circuit voltage of both welders.

1.i. When working above floor level, use a safety belt to protect yourself from a fall should you get a shock.

1.j. Also see Items 4.c. and 6.

WELD-PAK 100

3.b.

Do not weld in locations near chlorinated hydrocarbon coming from degreasing, cleaning or spraying operations. The heat and rays of the arc can react with solvent vapors form phosgene, a highly toxic gas, and other irritating products.

3.c. Shielding gases used for arc welding can displace air and cause injury or death. Always use enough ventilation, especially in confined areas, to insure breathing air is safe.

3.d. Read and understand the manufacturerʼs instructions for this

equipment and the consumables to be used, including the material safety data sheet (MSDS) and follow your employerʼs safety practices. MSDS forms are available from your welding distributor or from the manufacturer.

SAFETY

WELDING SPARKS can cause fire or explosion.

4.a.

Remove fire hazards from the welding area.

If this is not possible, cover them to prevent

the welding sparks from starting a fire.

materials from welding can easily go through small cracks and openings to adjacent areas. Avoid welding near hydraulic lines. Have a fire extinguisher readily available.

4.b. Where compressed gases are to be used at the job site, special precautions should be used to prevent hazardous situations. Refer to “Safety in Welding and Cutting” (ANSI Standard Z49.1) and the operating information for the equipment being used.

4.c. When not welding, make certain no part of the electrode circuit is touching the work or ground. Accidental contact can cause overheating and create a fire hazard.

4.d. Do not heat, cut or weld tanks, drums or containers until the proper steps have been taken to insure that such procedures will not cause flammable or toxic vapors from substances inside. They can cause an explosion even been “cleaned”. For information, purchase “Recommended Safe Practices for the Containers and Piping That Have Held Hazardous Substances”, AWS F4.1 from the American Welding Society

(see address above).

4.e. Vent hollow castings or containers before heating, cutting or welding. They may explode.

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

4.f. free protective garments such as leather gloves, heavy shirt, cuffless trousers, high shoes and a cap over your hair. Wear ear plugs when welding out of position or in confined places. Always wear safety glasses with side shields when in a welding area.

4.g. Connect the work cable to the work as close to the welding area as practical. Work cables connected to the building framework or other locations away from the welding area increase the possibility of the welding current passing through lifting chains, crane cables or other alternate circuits. This can create fire hazards or overheat lifting chains or cables until they fail.

4.h. Also see item 7c.

Remember that welding sparks and hot

though

they have

Preparation

for Welding and Cutting of

CYLINDER may explode if damaged.

5.a. Use only compressed gas cylinders containing the correct shielding gas for the process used and properly operating regulators designed for the gas and

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

5.b. Always keep cylinders in an upright position securely chained to an undercarriage or fixed support.

5.c. Cylinders should be located:

• Away from areas where they may be struck or subjected to

physical damage.

• A safe distance from arc welding or cutting operations and

any other source of heat, sparks, or flame.

5.d. Never allow the electrode, electrode holder or any other electrically “hot” parts to touch a cylinder.

5.e. Keep your head and face away from the cylinder valve outlet when opening the cylinder valve.

5.f. Valve protection caps should always be in place and hand tight except when the cylinder is in use or connected for use.

5.g. Read and follow the instructions on compressed gas cylinders, associated equipment, and CGA publication P-l, “Precautions for Safe Handling of Compressed Gases in Cylinders,” available from the Compressed Gas Association 1235 Jefferson Davis Highway, Arlington, VA 22202.

FOR ELECTRICALLY powered equipment.

SAFETY

FOR ENGINE powered equipment.

7.a. Turn the engine off before troubleshooting and maintenance work unless the maintenance work requires it to be running.

____________________________________________________

7.b. Operate engines in open, well-ventilated areas or vent the engine exhaust fumes outdoors.

____________________________________________________

7.c. Do not add the fuel near an open flame welding arc or when the engine is running. Stop the engine and allow it to cool before refueling to prevent spilled fuel from vaporizing on contact with hot engine parts and igniting. Do not spill fuel when filling tank. If fuel is spilled, wipe it up and do not start engine until fumes have been eliminated.

____________________________________________________

7.d. Keep all equipment safety guards, covers and devices in position and in good repair. Keep hands, hair, clothing and tools away from V-belts, gears, fans and all other moving parts when starting, operating or repairing equipment.

ELECTRIC AND MAGNETIC FIELDS may be dangerous

8.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

8.b. EMF fields may interfere with some pacemakers, and welders having a pacemaker should consult their physician before welding.

8.c. Exposure to EMF fields in welding may have other health effects which are now not known.

8d. All welders should use the following procedures in order to

minimize exposure to EMF fields from the welding circuit:

8.d.1.

Route the electrode and work cables together - Secure them with tape when possible.

8.d.2. Never coil the electrode lead around your body.

8.d.3. Do not place your body between the electrode and

work cables. If the electrode cable is on your right side, the work cable should also be on your right side.

8.d.4. Connect the work cable to the workpiece as close as

possible to the area being welded.

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

____________________________________________________

7.e. In some cases it may be necessary to remove safety guards to perform required maintenance. Remove guards only when necessary and replace them when the maintenance requiring their removal is complete. Always use the greatest care when working near moving parts.

7.f. Do not put your hands near the engine fan. Do not attempt to override the governor or idler by pushing on the throttle control rods while the engine is running.

7.g. To prevent accidentally starting gasoline engines while turning the engine or welding generator during maintenance work, disconnect the spark plug wires, distributor cap or magneto wire as appropriate.

___________________________________________________

7.h. To avoid scalding, do not remove the radiator pressure cap when the engine is hot.

SAFETY

PRÉCAUTIONS DE SÛRETÉ

Pour votre propre protection lire et observer toutes les instructions et les précautions de sûreté specifiques qui parraissent dans ce manuel aussi bien que les précautions de sûreté générales suivantes:

Sûreté Pour Soudage A LʼArc

1. Protegez-vous contre la secousse électrique:

a. Les circuits à lʼélectrode et à la piéce sont sous tension

quand la machine à souder est en marche. Eviter toujours tout contact entre les parties sous tension et la peau nue ou les vétements mouillés. Porter des gants secs et sans trous pour isoler les mains.

b. Faire trés attention de bien sʼisoler de la masse quand on

soude dans des endroits humides, ou sur un plancher metallique ou des grilles metalliques, principalement dans

les positions assis ou couché pour lesquelles une grande partie du corps peut être en contact avec la masse.

c. Maintenir le porte-électrode, la pince de masse, le câble

de soudage et la machine à souder en bon et sûr état defonctionnement.

d.Ne jamais plonger le porte-électrode dans lʼeau pour le

refroidir.

e. Ne jamais toucher simultanément les parties sous tension

des porte-électrodes connectés à deux machines à souder parce que la tension entre les deux pinces peut être le total de la tension à vide des deux machines.

f. Si on utilise la machine à souder comme une source de

courant pour soudage semi-automatique, ces precautions pour le porte-électrode sʼapplicuent aussi au pistolet de soudage.

5. Toujours porter des lunettes de sécurité dans la zone de soudage. Utiliser des lunettes avec écrans lateraux dans les zones où lʼon pique le laitier.

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

7. Quand on ne soude pas, poser la pince à une endroit isolé de la masse. Un court-circuit accidental peut provoquer un échauffement et un risque dʼincendie.

8. Sʼassurer que la masse est connectée le plus prés possible de la zone de travail quʼil est pratique de le faire. Si on place la masse sur la charpente de la construction ou dʼautres endroits éloignés de la zone de travail, on augmente le risque de voir passer le courant de soudage par les chaines de levage, câbles de grue, ou autres circuits. Cela peut provoquer des risques dʼincendie ou dʼechauffement des chaines et des câbles jusquʼà ce quʼils se rompent.

9. Assurer une ventilation suffisante dans la zone de soudage. Ceci est particuliérement important pour le soudage de tôles galvanisées plombées, ou cadmiées ou tout autre métal qui produit des fumeés toxiques.

10. Ne pas souder en présence de vapeurs de chlore provenant dʼopérations de dégraissage, nettoyage ou pistolage. La chaleur ou les rayons de lʼarc peuvent réagir avec les vapeurs du solvant pour produire du phosgéne (gas fortement toxique) ou autres produits irritants.

11. Pour obtenir de plus amples renseignements sur la sûreté, voir le code “Code for safety in welding and cutting” CSA Standard W 117.2-1974.

2. Dans le cas de travail au dessus du niveau du sol, se protéger contre les chutes dans le cas ou on recoit un choc. Ne jamais enrouler le câble-électrode autour de nʼimporte quelle partie du corps.

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

a. Utiliser un bon masque avec un verre filtrant approprié

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

b. Porter des vêtements convenables afin de protéger la

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

c. Protéger lʼautre personnel travaillant à proximité au

soudage à lʼaide dʼécrans appropriés et non-inflammables.

4. Des gouttes de laitier en fusion sont émises de lʼarc de soudage. Se protéger avec des vêtements de protection libres de lʼhuile, tels que les gants en cuir, chemise épaisse, pantalons sans revers, et chaussures montantes.

PRÉCAUTIONS DE SÛRETÉ POUR LES MACHINES À SOUDER À TRANSFORMATEUR ET À REDRESSEUR

1. Relier à la terre le chassis du poste conformement au code de lʼélectricité et aux recommendations du fabricant. Le dispositif de montage ou la piece à souder doit être branché à une bonne mise à la terre.

2. Autant que possible, Iʼinstallation et lʼentretien du poste seront effectués par un électricien qualifié.

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

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

Friction Brake Adjustment

1. With wire spool installed, check free movement and coast of the spool.

2. To tighten the brake turn the wing nut clockwise in 1/4 turn increments until coasting stops.

3. To loosen the brake turn the wing nut counterclockwise in 1/4 turn increments until the wire spool moves freely without coasting.

Wire Threading

Refer to Figure B-4

1. Release the Spring Loaded Pressure Arm (1) rotate the Idle Roll Arm (2) away from. the Wire Feed Drive Roll (3). Ensure that the groove size in the feeding position on the drive roll matches the wire size being used.

OPERATION

FIGURE B.4

The Wire Drive Feed Roll can accommodate two wire sizes by flipping the wire drive feed roll over.

2. Carefully detach the end of the wire from the spool. To prevent the spool from unwinding, maintain tension on the wire until after step 5.

3. Cut the bent portion of wire off and straighten the

first 4” (100 mm).

4. Thread the wire through the In-going guide tube (4), over the drive roll (3), and into the out-going guide tube (5).

5. Close the idle roll arm and latch the spring loaded pressure arm (2) in place . Rotate the spool counterclockwise if required in order to take up extra slack in the wire.

6. The idle roll pressure adjustment wing nut is normally set for mid-position on the pressure arm threads. If feeding problems occur because the wire is flattened excessively, turn the pressure adjustment counter-clockwise to reduce distortion of the wire. Slightly less pressure may be required when using 0.023 – 0.025” (0,6 mm) wire. If the drive roll slips while feeding wire, the pressure should be increased until the wire feeds properly.

7. Refer to Figure B.5. Remove gas nozzle and contact tip from end of gun.

8. Turn the WELD-PAK 100 ON (“I”).

9. Straighten the gun cable assembly.

10. Depress the gun trigger switch and feed welding wire through the gun and cable. (Point gun away from yourself and others while feeding wire.) Release gun trigger after wire appears at end of gun.

11. Turn the WELD-PAK 100 OFF (“O”).

12. Replace contact tip and gas nozzle.

Making A Weld

1. See “Process Guidelines” in this section for selection of welding wire and shielding gas and for range of metal thicknesses that can be welded.

2. See the Application chart on the inside of the wire feed compartment door for information on setting the WELD-PAK 100 controls. Refer to Table B.1 for aluminum and stainless wire.

3. Set the Voltage (“V”) and Wire Speed (“oloʼ”) controls to the settings suggested for the welding wire and base metal thickness being used, refer to Applications chart on the inside of the wire drive compartment door.

7. Position gun over joint. End of wire may be lightly touching the work.

8. Lower welding helmet, close gun trigger, and begin welding. Hold the gun so the contact tip to work distance is about 3/8 inch (10 mm).

9. To stop welding, release the gun trigger and then pull the gun away from the work after the arc goes out.

10. When no more welding is to be done, close valve on gas cylinder (if used), momentarily operate gun trigger to release gas pressure, and turn off the WELD-PAK 100.

Cleaning Tip And Nozzle

Clean the contact tip and nozzle to avoid arc bridging between the nozzle and contact tip which can result in a shorted nozzle, poor welds and an overheated gun. Hint: Anti-stick spray or gel, available from a welding supply distributor, may reduce buildup and aid in spatter removal.

4. Check that the polarity is correct for the welding wire being used and that the gas supply, if required, is turned on.

5. When using Innershield electrode, remove the gas nozzle and install the gasless nozzle. This will improve visibility of the arc and protect the gas diffuser from weld spatter. Refer to the MAINTE-

PROCESS GUIDELINES

The WELD-PAK 100 can be used for welding mild steel using the self shielded, Innershield electrode process or it can be used for the GMAW (MIG), single pass, process which requires a supply of shielding gas and the K610-1 MIG Conversion Kit.

The recommended electrode for the self-shielded process is 0.035” (0,9 mm) diameter Lincoln Innershield NR-211-MP on 10 Ib (4,5 kg) spools. Requires optional spindle – refer to Accessories section. This electrode can be used for all position welding of 20 gauge through 5/16” (1,0 – 8,0 mm) thick steel [multiple passes are required for 1/4” and 5/16” (6,0 and 8,0 mm)].

The recommended gas and electrode for GMAW is welding grade CO Lincoln L-56 mild-steel welding wire [supplied on 12-1/2 Ib (6 kg) spools]. For 14 gauge (2,0 mm) and

gas and 0.025” (0 6 mm) diameter

2. If using a regulator with an adjustable flow meter, close the gun trigger and adjust the flow to give 15 – 20 cubic ft per hour (CFH) (7 – 10 I/min) [use 20 – 25 CFH (10 – 12 I/min) when welding out of position or in a drafty location for CO

]. For argon

mixed gas, trigger to release gas pressure, and turn off the adjust the flow to give 25 – 30 CFH (12–14I/min).

3. Keep the cylinder valve closed, except when using the WELD-PAK 100. When finished welding:

a) Close the cylinder valve to stop gas flow.

b) Depress the gun trigger briefly to release the

pressure in the gas hose.

c) Turn off the WELD-PAK 100.

OVERLOAD PROTECTION

Output Overload

The WELD-PAK 100 is equipped with a circuit breaker and a thermostat which protects the machine from damage if maximum output is exceeded. The circuit breaker button will extend out when tripped. The circuit breaker must be manually reset.

Thermal Protection

The WELD-PAK 100 has a rated output duty cycle of 20%. If the duty cycle is exceeded, a thermal protector will shut off the output until the machine cools to a reasonable operating temperature. This is an automatic function of the WELD-PAK 100 and does not require user intervention. The fan continues to run during cooling.

Shielding Gas

When using the GMAW process, obtain and install the K610-1 MIG Conversion Kit and a cylinder of carbon dioxide (CO

) or argon-carbon dioxide mixed shielding

gas. Refer to the ACCESSORIES section for more information about installing the K610-1 Kit for use with the WELD-PAK 100.

LEARNING TO WELD

B-7

LEARNING TO WELD

No one can learn to weld simply by reading about it. Skill comes only with practice. The following pages will help the inexperienced operator to understand welding and develop this skill. For more detailed information, order a copy of “New Lessons in Arc Welding” listed at the end of this manual.

THE ARC-WELDING CIRCUIT

The operatorʼs knowledge of arc welding must go beyond the arc itself. The operator must know how to control the arc, and this requires a knowledge of the welding circuit and the equipment that provides the electric current used in the arc. Figure B.7 illustrates the welding circuit for a typical welding machine. The circuit begins where the gun cable is attached to the welding machine. Current flows through the gun cable, gun, and contact tip, to the wire and across the arc. On the work side of the arc, current flows through the base metal to the work cable and back to the welding machine. This circuit must be complete for the current to flow.

This machineʼs welding circuit has a voltage output of 32 volts DC maximum. This voltage is quite low and is only present when the gun triggers depressed.

To weld, the work clamp must be tightly connected to clean base metal. Remove paint, rust, dirt or oil as necessary and connect the work clamp as close as possible to the area you wish to weld. This helps prevent current from going through an unwanted path. Avoid allowing the welding circuit to pass through hinges, bearings, electronic components, or similar devices that can be damaged. See Figure B.8. Always disconnect electrical devices before welding upon them.

WARNING

Fumes and slag generated from Innershield type electrodes recommended for use with this welding machine can be toxic.

• Avoid contact with eyes and skin.

• Do not take internally.

• Keep out of reach of children.

• Follow all safety precautions found in this operating manual.

The gun and cable assembly is held by the operator who guides the automatically fed wire along the joint, maintaining a contact tip to work distance of about 3/8 to 1/2 inch (10 – 12 mm) This is called electrical stickout. This electrical stickout (ESO) must be properly maintained by the operator. The electric arc is made in the gap between the work and the tip end of a small diameter 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 operator controls the welding arc, and, therefore, the quality of the weld made.

THE SELF-SHIELDED FCAW WELDING ARC

Figure B.9 illustrates the action taking place in the self shielded FCAW (Innershield) welding arc. It closely resembles what is actually seen while welding.

Arc Stream

WELD-PAK 100

B-8

LEARNING TO WELD

The “arc stream” is seen in the middle of the picture. This is the electric arc created by the electric current flowing through the space between the end of the wire electrode and the base metal. The temperature of this arc is about 6000°F, which is more than enough to melt metal. The arc is very bright, as well as hot, and cannot be looked at with the naked eye without risking painful injury. The very dark lens, specifically designed for arc welding must be used with the hand or face shield whenever viewing the arc.

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

The function of the Innershield cored wire electrode is much more than simply to carry current to the arc. The wire core is composed of fluxes and/or alloying ingredients around which a steel sheath has been formed. It is simply a stick electrode turned inside out in a continuous wire form.

The cored wire melts in the arc and tiny droplets of molten metal shoot across the arc into the molten pool. The wire sheath provides additional filler metal for the joint to fill the groove or gap between the two pieces of base metal.

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

After running a weld bead, the slag may be removed with a chipping hammer and wire brush. This improves appearance and allows for inspection of the finished weld.

THE GMAW (MIG) WELDING ARC

Figure B.10 illustrates the GMAW (MIG) welding arc. Solid wire does not contain fluxes or ingredients to form its own shielding and no slag forms to protect the molten weld metal. For this reason, a continuous even flow of shielding gas is needed to protect the molten weld metal from atmospheric contaminants such as oxygen and nitrogen. Shielding gas is supplied through the gun and cable assembly, through the gas nozzle and into the welding zone.

FIGURE B.10

Gas nozzle

Solid wire electrode

Base metal

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

The recommended wire for Gas Metal Arc Welding (MIG) is Lincolnweld 0.025” L-56 electrode. Lincolnweld” L-56 is capable of welding a wide range of mild steels in all positions, however, more skill IS required for out-of-position welding with the GMAW process.

Shielding gas

Weld metal

Since machine size and output characteristics limit the size and type of wire electrode which can be used, Lincoln 0.035ʼ (0.9 mm) NR-211-MP Innershield electrode is recommended for Self-Shielded Flux Cored Arc Welding.

WELD-PAK 100

PROCESS SELECTION

By gaining knowledge of the differences between the two processes, you will be able to select the best process for the job you have at hand. In selecting a process, you should consider:

For GMAW (MIG) Process

1. Is most of my welding performed on 16 gauge and lighter materials?

LEARNING TO WELD

B-9

2. Can I afford the extra expense, space, and lack of portability required for gas cylinders and gas supply?

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

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

For FCAW (Innershield) Process

1. Do I want simplicity and portability?

2. Will welding be performed outdoors or under windy conditions?

3. Do I require good all position welding capability?

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

5. Weld must be cleaned prior to painting.

COMMON METALS

Most metals found around the farm, small shop or home are low carbon steel, sometimes referred to as mild steel. Typical items made with this type of steel include most sheet metal, plate, pipe and rolled shapes such as channels and angle irons. This type of steel can usually be easily welded without special precautions. Some steels, however, contain higher carbon levels or other alloys and are more difficult to weld. Basically, if a magnet sticks to the metal and you can easily cut the metal with a file, chances are good that the metal is mild steel and that you will be able to weld the material. In addition, aluminum and stainless steel can be welded using the K664-1 Aluminum Welding Kit. For further information on identifying various types of steels and other metals, and for proper procedures for welding them, we again suggest you purchase a copy of “New Lessons in Arc Welding”.

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

MACHINE SET UP FOR THE SELF-SHIELDED FCAW PROCESS

1. See PROCESS GUIDELINES in the OPERATION section for selection of welding wire and shielding gas, and for range of metal thicknesses that can be welded.

2. See the Application Guide on the inside of wire feed section door for information on setting the controls.

3. Set the “Voltage” and “Wire Speed” controls to the settings suggested on the Application Guide for the welding wire and base metal thickness being used. The voltage control is marked “V” and the wire feed speed is marked ʻʼolo.ʼʼ

4. Check that the polarity is correct for the welding wire being used. Set the polarity for DC(–) when welding with NR-211-MP Innershield electrode. See Work Cable Installation in the INSTALLATION section for instructions on changing polarity.

5. When using Innershield electrode, the gasless nozzle may be used instead of a gas nozzle to improve visibility of the arc.

6. Connect work clamp to metal to be welded. Work clamp must make good electrical contact to the work piece. The work piece must also be grounded as stated in the “Arc Welding Safety Precautions” at the beginning of this manual.

WELDING TECHNIQUES FOR THE SELFSHIELDED FCAW PROCESS

Four simple manipulations are of prime importance when welding. With complete mastery of the four, welding will be easy. They are as follows:

1. The Correct Welding Position

Figure B.11 illustrates the correct welding position for right handed people. (For left handed people, it is the opposite.)

Hold the gun (of the gun and cable assembly) in your right hand and hold the shield with your left hand. (Left handers simply do the opposite.)

When using the FCAW Process, weld from left to right (if you are right handed). This enables you to clearly see what you are doing. (Left handers do the opposite.) Tilt the gun toward the direction of travel holding the electrode at an angle as shown in Figure B.11.

WARNING

ARC RAYS can burn eyes and skin.

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

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

2. The Correct Way To Strike An Arc

1. Be sure the work clamp makes good electrical contact to the work.

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

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

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

The easiest way to tell whether the ESO is the correct length is by listening to its sound. The correct ESO has a distinctive “crackling” sound, very much like 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 weld puddle and/or fuse the wire to the contact tip.

4. The Correct Welding Speed

The important thing to watch while welding is the puddle of molten metal right behind the arc. See Figure B.13. Do not watch the arc itself. It is the appearance of the puddle and the ridge where the molten puddle solidifies that indicates correct welding speed. The ridge should be approximately 3/8” (10 mm) behind the wire electrode.

Most beginners tend to weld too fast, resulting in a thin uneven, “wormy” looking bead. They are not watching the molten metal.

FIGURE B.13

5. A ball may form at the tip end of the wire after welding. For easier restrikes (with Innershield wire) the ball may be removed by feeding out a few inches of wire and simply bending the wire back and forth until it breaks off.

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

3. The Correct Electrical Stickout (ESO)

The electrical stickout (ESO) is the distance from the end of the contact tip to the end of the wire.

See Figure B.12.

Once the arc has been established, maintaining the correct ESO becomes extremely important. The ESO should be approximately 3/8 to 1/2 inch (10 to 12 mm) long.

Helpful Hints

1. For general welding, it is not necessary to weave the 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 you will have to increase the welding speed, whereas when welding on heavy plate, it is necessary to go more slowly in order to get good penetration.

3. When welding sheet metal 16 gauge (1.5 mm) and lighter, heat buildup may cause part warpage and burn through. One way to eliminate these problems is to use the back-stepping method illustrated in Figure B.14.

FIGURE B.14

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

Back-Stepping

For the WELD-PAK 100, use the following:

Innershield Wire

Voltage Setting “V” D Wire Feed Speed “o|o” 3

Refer to Figure B.15.

1. Learn to strike an arc by positioning the gun over the 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 to work distance is about 3/8 to 1/2 inch (10 to 12 mm) and the gun is at proper angle.

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

Practice

The best way of getting practice in the four skills that enable 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.

FIGURE B.15

Contact Tip

5. When you are sure that you can hold the correct electrical stickout, with a smooth “crackling” arc start moving. Look at the molten puddle constantly.

6. Run beads on a flat plate. Run them parallel to the top edge (the edge farthest away from you). This gives you practice in running straight welds, and also gives you an easy way to check your progress. The 10th weld will look considerably better than the first weld. By constantly checking on your mistakes and your progress, welding will soon be a matter of routine.

2. See the Application Guide on the inside of wire feed section door for information on setting the controls.

4. Check that the polarity is correct for the welding wire being used. Set the polarity for DC(+) when welding with the GMAW (MIG) process. See Work Cable Installation in the INSTALLATION section for instructions for changing polarity.

5. Check that the gas nozzle and proper size liner and contact tip are being used and that the gas supply is turned on. If adjustable, set for 15 to 20 cubic feet per hour (7 to 10 l/min.) under normal conditions, increase to as high as 35 CFH (17 I/min.) under drafty (slightly windy) conditions.

Hold the gun (of the gun and cable assembly) in your right hand and hold the shield with your left hand. (Left handers simply do the opposite.)

1. Be sure the work clamp makes good electrical contact to the work.

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

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

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

5. A ball may form at the tip end of the wire after welding. For easier restrikes, the ball may be removed by feeding out a few inches of wire and cutting off the end of the wire with wire cutters.

6. When no more welding is to be done, close the valve on the gas cylinder, momentarily operate the gun trigger to release gas pressure, then turn off the machine.

ESO

3. The Correct Electrical Stickout (ESO)

The electrical stickout (ESO) is the distance from the end of the contact tip to the end of the wire. See Figure B.17.

Once the arc has been established, maintaining the correct ESO becomes extremely important. The ESO should be approximately 3/8 to 1/2 inch (10 to 12 mm) long.

Helpful Hints

1. For general welding, it is not necessary to weave the 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 you will have to increase the welding speed, whereas when welding on heavy plate, it is necessary to go more slowly in order to get good penetration.

Practice

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

1. Correct welding position

4. The Correct Welding Speed

The important thing to watch while welding is the puddle of molten metal right behind the arc. See Figure B.18. Do not watch the arc itself. It is the appearance of the puddle and the ridge where the molten Puddle solidifies that indicates correct welding speed. The ridge should be approximately 3/8” (10 mm) behind the wire electrode.

Most beginners tend to weld too fast, resulting in a thin, uneven, “wormy” looking bead. They are not watching the molten metal.

Refer to Figure B.15.

1. Learn to strike an arc by positioning the gun over the 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 to work distance Is about 3/8 to 1/2 inch (10 to 12 mm) and the gun is at proper angle.

WELD-PAK 100

B-14

LEARNING TO WELD

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

5. When you are sure that you can hold the correct electrical stickout, with a smooth “crackling” arc, start moving. Look at the molten puddle constantly,

JOINT TYPES AND POSITIONS

Five types of welding joints are: Butt Welds, Fillet Welds, Lap Welds, Edge Welds and Corner Welds. See Figure B.19.

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

Watch the molten metal to be sure it distributes itself evenly on both edges and in between the plates.

FIGURE B.20

Penetration

Unless a weld penetrates close to 100% of the metal thickness, a butt weld will be weaker than the material welded together. In the example shown in Figure B.21, the total weld is only half the thickness of the material thus the weld is only approximately half as strong as the metal.

FIGURE B.21

FIGURE B.19

Butt weld Lap weld

Edge weld Fillet weld Corner weld

Butt Welds

Place two plates side by side, leaving a space approximately one half the thickness of the metal between them 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.20.

Now weld the two plates together. Weld from left to right (if right handed). Point the wire electrode down in the crack between the two plates, keeping the gun slightly tilted in the direction of travel.

FIGURE B.22

In the example shown in Figure B.22, the joint has been welded so that 100% penetration could be achieved. The weld, if properly made, is as strong as or stronger than the original metal.

Fillet Welds

When welding fillet welds, it is very important to hold the wire electrode at a 45° angle between the two sides or the metal will not distribute itself evenly. The gun nozzle is generally formed at an angle to facilitate this. See Figure B.23.

WELD-PAK 100

LEARNING TO WELD

B-15

FIGURE B.23

45°

Welding In The Vertical Position

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

WARNING

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

Vertical-up And Overhead Welding

The problem, when welding vertical-up, is to put the molten metal where it is wanted and make it stay there. If too much molten metal is deposited, gravity will pull it downwards and make it “drip”. Therefore, a certain technique has to be followed.

FIGURE B.24

PROPER GUN ANGLE FOR GMAW PROCESS WELDING IN THE VERTICAL UP POSITION

PROPER GUN ANGLE FOR FCAW PROCESS WELDING IN THE VERTICAL UP POSITION

Vertical-down Welding

Refer to Figure B.25 Vertical-down welds are applied at a fast pace. These welds are therefore shallow and narrow 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 of travel so the arc force helps hold the molten metal in the joint. Move as fast as possible consistent with desired bead shape.

The important thing is to continue lowering the entire arm as the weld is made so the angle of the gun does not change. Move the electrode wire fast enough that the slag does not catch up with the arc. Vertical-down welding gives thin, shallow welds. It should not be used on heavy material where large welds are required.

FIGURE B.25

When welding out-of-position, run stringer beads. Donʼt whip, break the arc, move out of the puddle, or move too fast in any direction. Use Wire Feed Speed (WFS) in the low portion of the range. The general technique and proper gun angle is illustrated in Figure B.24.

Generally, keep the electrode nearly perpendicular to the joint as illustrated. The maximum angle above perpendicular may be required if porosity becomes a problem.

Most feeding problems are caused by improper handling 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 when welding.

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

4. Keep the cable clean.

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

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

GUN AND CABLE MAINTENANCE

FOR MAGNUM™ 100L GUN

Gun Cable Cleaning

Clean cable liner after using approximately 300 lbs (136 kg) of solid wire or 50 lbs (23 kg) of flux-cored wire. Remove the cable from the wire feeder and lay it out straight on the floor. Remove the contact tip from the gun. Using low pressure air, gently blow out the cable liner from the gas diffuser end.

CAUTION

Excessive pressure at the start may cause the dirt to form a plug.

Flex the cable over its entire length and again blow out the cable. Repeat this procedure until no further dirt comes out.

5. To remove gun tube from gun, remove gas nozzle or gasless nozzle and remove diffuser from gun tube. Remove both collars from each end of the gun handle and separate the handle halves. Loosen the locking nut holding the gun tube in place against the gun end cable connector. Unscrew gun tube from cable connector. To install gun tube, screw the locking nut on the gun tube as far as possible. Then screw the gun tube into the cable connector until it bottoms. Then unscrew (no more than one turn) the gun tube until its axis is perpendicular to the flat sides of the cable connector and pointed in the direction of the trigger. Tighten the locking nut so as to maintain the proper relationship between the gun tube and the cable connector. Replace the gun handle, trigger and diffuser. Replace the gas nozzle or gasless nozzle.

Contact Tips, Nozzles, and Gun Tubes

1. Dirt can accumulate in the contact tip hole and restrict wire feeding. After each spool of wire is used, remove the contact tip and clean it by pushing a short piece of wire through the tip repeatedly. Use the wire as a reamer to remove dirt that may be adhering to the wall of the hole through the tip.

2. Replace worn contact tips as required. A variable or “hunting” arc is a typical symptom of a worn contact tip. To install a new tip, choose the correct size contact tip for the electrode being used (wire size is stenciled on the side of the contact tip) and screw it snugly into the gas diffuser.

3. Remove spatter from inside of gas nozzle and from tip after each 10 minutes of arc time or as required.

4. Be sure the gas nozzle is fully screwed onto the diffuser for gas shielded processes. For the Innershield the gasless nozzle should be screws onto the diffuser.

The Procedure Handbook of Arc Welding

With over 500,000 copies of previous editions published since 1933, the Procedure Handbook is considered by many to be the “Bible” of the arc welding industry.

This printing will go fast so donʼt delay. Place your order now using the coupon below.

The hardbound book contains over 750 pages of welding information, techniques and procedures. Much of this material has never been included in any other book.

A must for all welders, supervisors, engineers and designers. Many welding instructors will want to use the book as a reference for all students by taking advantage of the low quantity discount prices which include shipping by 4th class parcel post.

$15.00 postage paid U.S.A. Mainland

How To Read Shop Drawings

The book contains the latest information and application data on the American Welding Society Standard Welding Symbols. Detailed discussion tells how engineers and draftsmen use the “short-cut” language of symbols to pass on assembly and welding information to shop personnel.

New Lessons in Arc Welding

Lessons, simply written, cover manipulatory techniques; machine and electrode characteristics; related subjects, such as distortion; and supplemental information on arc welding applications, speeds and costs. Practice materials, exercises, questions and answers are suggested for each lesson.

528 pages, well illustrated, 6” x 9” size, bound in simulated, gold embossed leather.
