5WG3000 and WG3060switch until the wire feeds out pastthe torch end. Turn welder off.9. Carefully slip the contact tip over thewire and screw it into the torch neck.Install the nozzle by turning clock-wise (See Figure 6). Cut the wire offapproximately 1/4” from the end ofthe nozzle.POLARITYFor gas shielded welding, connect thecable coming out of the torch to the (+)socket and the work clamp cable to the(-) socket on the front panel. For flux-core (no-gas) welding, connect torch to(-) and work clamp to (+).DUTY CYCLE / THERMOSTATICPROTECTIONWelder duty cycle is the percentage ofactual weld time that can occur in a tenminute interval. For example, at a 10%duty cycle, actual welding can occur forone minute, then the welder must coolfor nine minutes.Internal components of this welder areprotected from overheating with anautomatic thermal switch. A yellowlamp is illuminated on the front panelif the duty cycle is exceeded. Weldingoperations may continue when theyellow lamp is no longer illuminated.MODEL WT10001. Remove the lens retainer from theface shield with a regular screwdriverby prying against the shield and postof the lens retainer.2. Remove the protective film coveringfrom both sides of each lens cover.Put one clear lens cover on each sideof the shaded lens. Place these threelenses together into the face shieldand secure with the lens retainer. Thelens retainer should snap into thesecond notch in the face shield.3. Position one of the holes in theadjustment arm over the pins whichare located in the ear area of the faceshield. These adjustment arms controlthe closeness of fit and can be easilyrepositioned if necessary.4. Position the headgear inside the faceshield. Assemble the helmet byinserting the stud screw through theheadgear and shield into the tensionnut as shown. Do not tighten tensionnut completely.5. Trial fit the welding helmet. Adjustheadgear ratchet band to acomfortable position and lower theface shield. If the shield is too far ortoo close to the face, use a differenthole in the adjustment arm. Adjustthe tension nuts so that helmet can beeasily lowered over the face bynodding the head.Improper handlingand maintenanceof compressed gas cylinders andregulators can result in serious injuryor death! Always secure gas cylindersto the tank bracket kit, a wall or otherfixed support to prevent the cylinderfrom falling over. Read, understand,and follow all the compressed gasesand equipment hazards in the safetyinstructions.NOTE: Shielding gas is not required ifflux-cored welding wire is used.GAS TYPESThere are 3 types of gas generally usedfor gas metal arc welding; 100% argon,a mixture of 75% argon and 25%carbon dioxide (C25) or 100% carbondioxide. However, 100% carbondioxide is not recommended due tounsatisfactory weld beads. This welderdoes not perform well with 100%carbon dioxide. The 75/25 mixture isrecommended for general steelwelding. For aluminum welding, use100% argon. Cylinders of either typegas may be obtained at your localwelding supply outlet. Secure cylinderin place on your welding machine orother support to prevent the cylinderfrom falling over.NOTE: Use of incorrect gas may lead tolittle or no penetration of weldingelectrode (wire).REGULATORThe regulator provides a constantshielding gas pressure and flow rateduring the welding process. Eachregulator is designed to be used with aspecific gas or mixture of gases. Theargon and argon mixture use the samethread type. The 100% carbon dioxideuses a different thread type. An adapteris available at your local welding gassupplier to change between the two.HOOKUP PROCEDURECylinder gas isunder highpressure. Point cylinder outlet awayfrom yourself and any bystandersbefore opening.1. These units fit a 20 cubic ft bottle.2. With the cylinder securely installed,remove the cylinder cap, stand to theside of the cylinder opposite theoutlet, and open the valve slightly,turning counterclockwise. When gasis emitted from the cylinder, close thevalve by turning clockwise. This willblow out dust or dirt that may haveaccumulated around the valve seat.3. Install the regulator onto thecylinder valve, keeping the face ofthe gauges in the vertical positionand tighten the stem nut securely tothe gas valve.4. Install one end of the gas hose tothe fitting on the rear of the welderand the other end to the fitting onthe regulator using hose clamps oneach connection. Make sure the gashose is not kinked or twisted.5. Once again, stand opposite thecylinder outlet and slowly open thecylinder valve. Inspect for leaks inthe connections.6. Pull the trigger on the gun to allowthe gas to flow. While the trigger ispulled and gas is flowing, adjust thegas regulator to 30-35 cfh (cubicfeet per hour)*. Release the trigger.Contact Tip MarkingsWire Size mm.024” or .6.030” or .8.035” or .9.040” or 1.0Assembly (Continued)Figure 7HeadgearFace ShieldShaded LensClear Lens Cover (2)PostLens RetainerAdjustmentArm (2)Tension Nut (2)Stud Screw (2)Welding HelmetAssemblyShielding GasInstallationwww.campbellhausfeld.com
