Mount the metal to be welded to the 2. metal work table. It should be mounted so that the welding debris falls to the cement floor. Place the Welder no closer than six 3. feet from the workpiece to be welded and attach the Tig Torch, if desired. Securely attach the Ground Clamp 4. (9) to a part of the workpiece or metal table. (See Figure A.) Place the bare end of an Electrode 5. (not included) in the Electrode Holder (8). NOTE: Always keep the jaws of the Electrode Holder clean to ensure proper electrical contact with the Electrode. (See Figure A.) Set the desired current on the Poten6. tiometer Dial (4) from 10 to130 amps for the type of metal being welded. Thin metals use low current and heavy metals use high current. (See Figure B.) Make sure the Power Switch (16) is 7. OFF. Then plug the Welder’s Power Cord (17) into the nearest 240 volt, dedicated, grounded, electrical outlet with delayed action type circuit breaker or fuse. (See Figure C.) While gripping the Handle of the 8. Electrode Holder (8), with the Electrode clear of grounded objects, turn the Power Switch (16) ON. (See Figure C.) Hold the Electrode Holder (8) firmly. 9. CAUTION! The Electrode Holder is “live”. (See Figure A.) WARNING! 10. Never look at the ignited arc without ANSI-approved, arc shaded, eye protection in a full face shield. Permanent eye damage or blindness can occur. Skin burns can occur. REV 09h Wear a NIOSH-approved respirator to avoid breathing arc fumes. Stroke the area to be welded with the 11. Electrode to ignite the arc. Never tap the Electrode into the welding surface to ignite the arc. This damages its external coating on the Electrode which prevents oxygen in the air from coming into contact with the molten metal, causing it to oxidize. Once the arc is ignited, tilt the Elec12. trode forward at an angle of approximately 30° and hold it at a distance from the welding object equal to the diameter of the Electrode. NOTE:13. If too much current is drawn from the Welder, the internal Thermal Overload Protector will activate. The Yellow “Overheating” Light (5) will illuminate, and the Welder will automatically shut off until it cools down. Please wait until the welder automatically restarts after the yellow “overheating” light turns off. (See Figures B and C.) When the weld is complete, lift the 14. Electrode clearly away from any grounded object. Then turn the Power Switch (16) OFF. (See Figure C.) Unplug the Power Cord (17) from its 15. electrical outlet. Remove the Ground Clamp (9) from 16. the workpiece it is clamped onto. Then remove the Electrode from the Electrode Holder (8). (See Figure A.) Allow all components of the Welder 17. to completely cool. Then clean and store the Welder indoors out of reach of children and other unauthorized persons. IMPORTANT: Refer to the included 18. “Weld Diagnoses” pamphlet for tips and suggestions regarding proper welding. TIG Torch Operating Instructions Please Note: The following instructions are for Tig Welding using the Tig Torch. To prevent serious injury and death: Do not touch the tip of the Torch when the welder is connected to power. The Torch will immediately activate when it is plugged in. The operator must carefully direct the torch whenever the welder is connected to power. When the operator is not holding the Torch, it must be sitting on a nonconductive, nonflammable surface. Feed the filler metal being used into the arc with a properly insulated holder (not included). To use Tig Torch, first disconnect 1. Electrode Holder (8). Attach the welder’s Ground Clamp 2. to a clean uncoated metal part of the workpiece near the welding location. Close the Gas Flow Knob on the 3. torch completely, turning it clockwise until it stops. Turn the argon gas supply on. Hold the torch in a safe direction4. , plug the welder’s power cord into a Danger REV 09h grounded, 240 V~, GFCI-protected receptacle and turn the Welder on. Turn the Gas Flow Knob on the torch 5. counterclockwise to allow the shielding gas to flow. Tilt the torch forward, towards the 6. workpiece. Keep a constant distance between the torch and the workpiece but do not contact it. Feed the filler metal into the arc 7. with a properly insulated holder (not included). Turn Gas Flow Knob on TIG torch to 8. adjust the flow of shielding gas. After welding, hold Torch in a safe di9. rection, turn off the welder, close the Gas Flow Knob on the torch (clockwise), and unplug the welder. Then, place the torch on a nonconductive, nonflammable surface, and close the argon supply at the argon bottle. Maintenance And Servicing Procedures not specifically explained in this manual must be performed only by a qualified technician. To prevent serious injury from accidental operation: Turn the Power Switch (16) of the Welder to its “OFF” position and unplug the tool from its electrical outlet before performing any inspection, maintenance, or cleaning procedures. To prevent serious injury from tool failure: Do not use damaged equipment. I...
