Anleitung Zusammenfassung
The RED Overload Indicator Light will illuminate and the Welder will automatically turn off until it cools down. If this happens, turn the Power Switch to its “OFF” position and wait approximately 20 minutes. (See Figure L.) Wire Speed Control Knob (17): 2. The Scale surrounding the Knob is relative value, not wire feed speed. (See Figure L.) Voltage Controls (18, 19): 3. Adjust the Voltage Controls based on thickness of metal being welded. (See Figure L.) If using solid-core wire, connect and secure an Argon/ CO4. 2 gas hose to the rear of the Welder. (If using flux core wire, protective gas is not required.)

Securely clamp the Ground Clamp (14) as close as possible to the metal object to be welded, or to the metal workbench where the object is mounted and electrically connected. (See Figure L.) NOTE: 6. The workpieces should be firmly held together and in position while welding. Use clamps (not included) to hold the workpieces so you can concentrate on the job at hand. The distance (if any) between the two workpieces must be controlled properly to allow the weld to hold both sides securely while allowing the weld to penetrate fully into the joint. Set the desired welding current (30 to 140 amps) for the type of metal being welded, 7. using the Wire Speed Control Knob (17) and Voltage Controls (18, 19). (See Figure L.) Make sure the Power Switch is in its 8. “OFF” position. Then plug Power Cord of the Welder into a dedicated, 220 VAC, 25 amp line with delayed action type circuit breaker or fuse. While holding the Welding Torch (15), with the Welding Wire clearly out of the way 9. of any grounded objects, turn the Power Switch to its “ON” position. Momentarily squeeze the Trigger (15d) of the Welding Torch (15) to test the wire 10. feed speed. If necessary, adjust the speed by turning the Wire Speed Control Knob (17). (See Figure L.) Orient yourself on the area to be welded, then place a Face Shield over your 11. eyes. 12. 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 breathe arc fumes. (See page 8.) Holding The Welding Torch Hold the Welding Torch (15) in one hand and the face shield in the other. If a hands-13. free welding shield is used, then both hands can be used to control the Welding Torch. The Welding Wire should be directed straight into the joint. 14. This gives an angle of 90 degrees (straight up and down) for groove (end to end) welds, and an angle of 45 degrees for fillet (T-shaped) welds. The end of the Welding Torch should be tilted so that the 15. Welding Wire is angled anywhere in between straight on and 15 degrees in the direction of the weld. The amount of tilt is called the “drag angle”. (See Figure M.) The Welding Wire should extend no more than 1/2” past the 16. Nozzle (15h) of the Welding Torch (15). This distance is called “stickout”. (See Figure M.) Set the Wire Speed and Voltage Controls (17, 18, 19) to the recommended start 17. settings as shown in the Weld Settings Chart on the next page. (See Figure N.) FIGURE M Weld Settings Chart FIGURE N Top figures are Voltage Settings. Bottom number is Wire Speed Setting.

The settings should only be used at the beginning of a weld and must be adjusted after stopping and carefully inspecting the weld. Proper welding takes good technique and practice. Welding Instructions continued on next page. Squeeze (and hold) the Trigger Switch (15d) of the Welding Torch (15) and stroke 18. the area to be welded with the Welding Wire to ignite the arc. Never tap the Welding Wire into the welding surface to ignite the arc. This will a. cause the Welding Wire to stick to the workpiece. For a narrow weld, you can usually draw the Welding Wire in a steady straight b. line. This is called a “stringer bead”. For a wider weld, draw the Welding Wire back and forth across the joint in a c. curve. This is called a “weave bead”. Note: If too much current is drawn from the Welder, the internal Thermal Overload Protector will activate. The Overload Indicator Light (28) will illuminate and the Welder will automatically turn off. If this happens, turn the Power Switch to its “OFF” position a...
