Push in until the wire comes out the Welding Torch head. If it cannot be fed manually all the way out, it can be fed automatically when the welding unit is powered up. 6. Close the Feed Mechanism (10) over the wire, and adjust the feed tension (D) if necessary. 7. Check that +/– cables to connection Knobs (29) are correct. See photo (top-left). When using non-flux wire and protective gas, connect wire cables as shown in photo. For 0.9 flux cored wire, no gas is required. Reverse cable connections. 8. Close the Side Panel B (1).

If using non-flux core wire, connect and secure the Argon / CO2 gas hose to the rear of the MIG Welder. (If using flux core wire, protective gas is not required.) 2. Attach the Ground Cable with Clamp (14) as close as possible to the metal object to be welded, or to the metal work bench where the object is mounted and electrically connected. 3. Set the desired welding current (30~120 amps) for the type of metal being welded using the Min/Max Switch and 1/2 Power Level Switch. Refer to the power setting table on the next page. Thinner metals use lower current. Heavier metals use higher current. 4. Verify that the On/Off Switch is in the OFF position, then plug the MIG Welder Line Cord into a dedicated, 120 VAC, 20 amp line with delayed action type circuit breaker or fuses. If an extension cord is used, it must have the following wire size: up to 30 feet, use 10 AWG size wire; 30 to 50 feet, 8 AWG wire; Over 50 feet, 6 AWG wire.

While holding the Welding Torch handle, with the electrode wire clearly out of the way of any grounded objects, turn the On/Off Switch to the ON position. 6. Momentarily press the Welding Torch trigger switch to test the wire feed speed. Adjust the speed by turning the Wire Feed Speed Control knob. 7. Orient yourself on the area to be welded, then hold the Arc Shaded Face Shield over your eyes. Warning: 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. Never breath arc fumes. 8. Press (and hold) the Torch Trigger Switch and stroke the area to be welded with the electrode wire to ignite the arc. Never tap the electrode wire 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. 9. Once the arc is ignited, tilt the electrode wire forward at an angle of about 35°. Refer to the illustration at right. The wire feeds automatically at a speed dependent on the Min. or Max. current setting. The wire speed can also be adjusted using the Wire Feed Speed Control. Note: If too much current is drawn from the MIG Welder, the Thermal Overload protector will activate, the red Overload indicator will light, and the Arc Welder will turn off until it cools down. If this happens, turn the On/Off Switch to the OFF position and wait about 3 ~ 5 minutes. 10. When the weld is complete, lift the Welding Torch handle electrode wire clearly away from any grounded object, remove your Face Shield, and turn the On/Off Switch to the OFF position. 11. Unplug the power Line Cord from the electrical outlet. SKU 06098 Page 8 Troubleshooting Symptom MIG Welder does not work when turned on. Possible Cause No power to MIG Welder. Checks and Remedies Check Line Cord and plug. Check facility circuit breaker. Overheated during use. In overload mode; Allow to cool down. Wire does not feed properly. Insufficient wire feed spring tension. Tighten spring tension knob. See photo on page 6. Wire guide sheath blocked. Clean or replace wire sheath. Wire spool axle nut too tight. Loosen nut so reel moves freely. Braking on wire reel excessive. Loosen brake using adjusting screw. Reduced welding power. Wire reel has oxidized, poorly wound or quality wire. Ground Cable not connected or poor connection. Replace wire reel. Check that the Ground Cable Clamp is securely attached to the metal being welded. This area should be cleaned down to the metal and free of paint, dirt and grease. Internal connection loose on switches. Faulty contactor. One or more rectifiers failed. A qualified technician should open the unit and check and tighten any loose connectors. Check the state of the contacts and the mechanical operation of the contactors. A qualified technician should open the unit...
