WARNING: These Safety Precautions are foryour protection. They summarize precautionaryinformation from the references listed in Addi-tional Safety Information section. Before per-

forming any installation or operating procedures, be sure toread and follow the safety precautions listed below as well asall other manuals, material safety data sheets, labels, etc.Failure to observe Safety Precautions can result in injury ordeath.

PROTECT YOURSELF AND OTHERS --Some welding, cutting, and gouging pro-cesses are noisy and require ear protec-tion. The arc, like the sun, emits ultravio-let (UV) and other radiation and can

injure skin and eyes. Hot metal can cause burns. Train-ing in the proper use of the processes and equipment isessential to prevent accidents. Therefore:

1. Always wear safety glasses with side shields in any workarea, even if welding helmets, face shields, and gogglesare also required.

2. Use a face shield fitted with the correct filter and coverplates to protect your eyes, face, neck, and ears fromsparks and rays of the arc when operating or observingoperations. Warn bystanders not to watch the arc and notto expose themselves to the rays of the electric-arc or hotmetal.

3. Wear flameproof gauntlet type gloves, heavy long-sleeveshirt, cuffless trousers, high-topped shoes, and a weldinghelmet or cap for hair protection, to protect against arcrays and hot sparks or hot metal. A flameproof apron mayalso be desirable as protection against radiated heat andsparks.

4. Hot sparks or metal can lodge in rolled up sleeves, trousercuffs, or pockets. Sleeves and collars should be keptbuttoned, and open pockets eliminated from the front ofclothing

5. Protect other personnel from arc rays and hot sparks witha suitable non-flammable partition or curtains.

6. Use goggles over safety glasses when chipping slag orgrinding. Chipped slag may be hot and can fly far. By-standers should also wear goggles over safety glasses.

FIRES AND EXPLOSIONS -- Heat fromflames and arcs can start fires. Hot slagor sparks can also cause fires and explo-sions. Therefore:

1. Remove all combustible materials well away from thework area or cover the materials with a protective non-flammable covering. Combustible materials include wood,cloth, sawdust, liquid and gas fuels, solvents, paints andcoatings, paper, etc.

2. Hot sparks or hot metal can fall through cracks or crevicesin floors or wall openings and cause a hidden smolderingfire or fires on the floor below. Make certain that suchopenings are protected from hot sparks and metal.“

3. Do not weld, cut or perform other hot work until theworkpiece has been completely cleaned so that there areno substances on the workpiece which might produceflammable or toxic vapors. Do not do hot work on closedcontainers. They may explode.

4. Have fire extinguishing equipment handy for instant use,such as a garden hose, water pail, sand bucket, orportable fire extinguisher. Be sure you are trained in itsuse.

SAFETY PRECAUTIONS

11/95

5. Do not use equipment beyond its ratings. For example,overloaded welding cable can overheat and create a firehazard.

6. After completing operations, inspect the work area tomake certain there are no hot sparks or hot metal whichcould cause a later fire. Use fire watchers when neces-sary.

7. For additional information, refer to NFPA Standard 51B,"Fire Prevention in Use of Cutting and Welding Pro-cesses", available from the National Fire Protection Asso-ciation, Batterymarch Park, Quincy, MA 02269.

ELECTRICAL SHOCK -- Contact withlive electrical parts and ground cancause severe injury or death. DO NOTuse AC welding current in damp areas,if movement is confined, or if there isdanger of falling.

1. Be sure the power source frame (chassis) is connectedto the ground system of the input power.

2. Connect the workpiece to a good electrical ground.3. Connect the work cable to the workpiece. A poor or

missing connection can expose you or others to a fatalshock.

4. Use well-maintained equipment. Replace worn or dam-aged cables.

5. Keep everything dry, including clothing, work area, cables,torch/electrode holder, and power source.

6. Make sure that all parts of your body are insulated fromwork and from ground.

7. Do not stand directly on metal or the earth while workingin tight quarters or a damp area; stand on dry boards oran insulating platform and wear rubber-soled shoes.

8. Put on dry, hole-free gloves before turning on the power.9. Turn off the power before removing your gloves.

10. Refer to ANSI/ASC Standard Z49.1 (listed on next page)for specific grounding recommendations. Do not mistakethe work lead for a ground cable.

ELECTRIC AND MAGNETIC FIELDS— May be dangerous. Electric currentflowing through any conductor causeslocalized Electric and Magnetic Fields(EMF). Welding and cutting currentcreates EMF around welding cablesand welding machines. Therefore:

1. Welders having pacemakers should consult their physi-cian before welding. EMF may interfere with some pace-makers.

2. Exposure to EMF may have other health effects which areunknown.

3. Welders should use the following procedures to minimizeexposure to EMF:A. Route the electrode and work cables together. Secure

them with tape when possible.B. Never coil the torch or work cable around your body.C. Do not place your body between the torch and work

cables. Route cables on the same side of your body.D. Connect the work cable to the workpiece as close as

possible to the area being welded.E. Keep welding power source and cables as far away

from your body as possible.

FUMES AND GASES -- Fumes andgases, can cause discomfort or harm,particularly in confined spaces. Donot breathe fumes and gases. Shield-ing gases can cause asphyxiation.Therefore:

1. Always provide adequate ventilation in the work area bynatural or mechanical means. Do not weld, cut, or gougeon materials such as galvanized steel, stainless steel,copper, zinc, lead, beryllium, or cadmium unless positivemechanical ventilation is provided. Do not breathe fumesfrom these materials.

2. Do not operate near degreasing and spraying operations.The heat or arc rays can react with chlorinated hydrocar-bon vapors to form phosgene, a highly toxic gas, andother irritant gases.

3. If you develop momentary eye, nose, or throat irritationwhile operating, this is an indication that ventilation is notadequate. Stop work and take necessary steps to improveventilation in the work area. Do not continue to operate ifphysical discomfort persists.

4. Refer to ANSI/ASC Standard Z49.1 (see listing below) forspecific ventilation recommendations.

CYLINDER HANDLING -- Cylinders, ifmishandled, can rupture and violentlyrelease gas. Sudden rupture of cylin-der, valve, or relief device can injure orkill. Therefore:

1. Use the proper gas for the process and use the properpressure reducing regulator designed to operate from thecompressed gas cylinder. Do not use adaptors. Maintainhoses and fittings in good condition. Follow manufacturer'soperating instructions for mounting regulator to a com-pressed gas cylinder.

2. Always secure cylinders in an upright position by chain orstrap to suitable hand trucks, undercarriages, benches,walls, post, or racks. Never secure cylinders to worktables or fixtures where they may become part of anelectrical circuit.

3. When not in use, keep cylinder valves closed. Have valveprotection cap in place if regulator is not connected.Secure and move cylinders by using suitable hand trucks.Avoid rough handling of cylinders.

4. Locate cylinders away from heat, sparks, and flames.Never strike an arc on a cylinder.

5. For additional information, refer to CGA Standard P-1,"Precautions for Safe Handling of Compressed Gases inCylinders", which is available from Compressed GasAssociation, 1235 Jefferson Davis Highway, Arlington,VA 22202.

EQUIPMENT MAINTENANCE -- Faulty or im-properly maintained equipment can causeinjury or death. Therefore:

1. Always have qualified personnel perform the installation,troubleshooting, and maintenance work. Do not perform

any electrical work unless you are qualified to performsuch work.

2. Before performing any maintenance work inside a powersource, disconnect the power source from the incomingelectrical power.

3. Maintain cables, grounding wire, connections, power cord,and power supply in safe working order. Do not operateany equipment in faulty condition.

4. Do not abuse any equipment or accessories. Keep equip-ment away from heat sources such as furnaces, wetconditions such as water puddles, oil or grease, corrosiveatmospheres and inclement weather.

5. Keep all safety devices and cabinet covers in position andin good repair.

6. Use equipment only for its intended purpose. Do notmodify it in any manner.

1. Screw in collet body. (If using a gas lens,assemble insulator on collet body beforeinstalling.)

2. Apply a thin coat of silicone grease to thesurface of the cup that mates with the torchbody and then screw on cup.

3. Remove torch cap and slide collet into posi-tion (tapered end first).

4. Slip electrode down through hole in top ofcollet until end of electrode extends beyondrim of cup. (Exact extension is variable fromas little as 1/8 inch for butt welding withstandard collet bodies to 3/4 inch or more forcorner or fillet welds with gas lens colletbodies and cups.)

NOTE

When using high frequency with sleeved high-impact cups, arcing may sometimes occur be-tween the electrode and the steel sleeve. Toavoid this, it is advantageous to extend theelectrode as far as possible consistent with theparticular application.

5. Screw on the torch cap and tighten. The capwill press down on the collet to grip theelectrode securely. To readjust electrode,loosen torch cap.

3.1 Maintenance

If this equipment does not operate properly, stop workimmediately and investigate the cause of the malfunc-tion. Maintenance work must be performed by an expe-rienced person and electrical work by a trained electri-cian. Do not permit untrained persons to inspect, clean,or repair this equipment. use only recommended re-placement parts.

A. A poor shielding gas connection, or a leakyhose, will not only waste gas but permit the entryof minute amounts of air, sufficient to contami-nate both the electrode and the weld. Troublesigns: a bluish cast on the electrode after it hascooled; in welding aluminum, a dark gray de-posit on or beside the weld bead.

B. If the argon valve leaks or operates improperly,disassemble the valve as follows:

1. Unscrew the valve stem assembly (P/N598279) until it clears the torch body.

2. Lift out and inspect the valve stem assem-bly. If the stem or ball valve is damaged,replace the entire assembly with a new one.If the stem is in good condition, inspect thetwo "O" rings. If they are worn, replace withnew ones.

NOTE

Prior to installing the new "O" ring, apply athin coat of silicone grease.

3. Reinstall the valve stem assembly, makingsure that the assembly is fully screwed intothe torch body so that the ball valve will seatproperly when the valve is in the closedposition.

C. Do not try to repair concentric power cable,replace it. Two piece cable and hose assembliesmay be repaired using the repair kits noted inparts breakdown. The kits include replacementfittings and lug for the cable and hose.

D. If an electrode becomes contaminated, shut offpower, then remove electrode from torch. Breakoff the contaminated end (nicking with a grindingwheel first will help) and replace electrode.

E. Keep an eye on the sealing "O" ring on the torchcap. If it shows signs of wear or distortion, cut itoff. Then install new ring (P/N 98W18). Apply alittle silicone grease to the new ring beforeattempting to slide it over the cap threads.

3.2 Replacement of Gas Lens Screens In P/Ns45V63, 995795, and 45V64 (See Figure 3-1)

Large diameter gas lens collet bodies contain re-placeable screens. If plugged by spatter, replace asfollows:

A. With the collet body removed from the torch,remove the outer snapring (P/N 54N71). Thiscan be done by using a small screwdriver, or anelectrode with a diameter no greater than 3/32in. Insert the tip in the slot on the outer sleeve ofthe collet body, and pry out the snapring.

B. Using a pair of needle nose pliers, pry out theinner snapring (P/N 54N69).

C. Hold the collet body with the screens down, andgently tap the body on the work bench. The bodycontains three fine and one coarse screens,separated by spacers. If the screens are notbadly fouled, they should drop out of the body.Excessive fouling may necessitate prying outthe screens.

D. Inspect the screens and replace those whichshow plugging or other damage.

E. Replace the screens and spacers making surethat a spacer is installed between each screen,and that the coarsest screen is inserted last.Replace the snaprings.
