BRINGING WELDING WIRE THROUGH THE TORCH HEAD

10.Turn the torch handle nozzle (7) counterclockwise and pull to remove.

11.Turn contact tip (8) counterclockwise and remove.

12.Lay torch sheath out in a straight line so the flux-core wire moves through easily.

13.Plug the welder’s power cord into an approved AC outlet.

14.Press the current switch to “MAX” and turn the welder “ON.”

15.Lift torch handle and press trigger (9) until 2" of wire feeds through the tip.

16.If the wire does not feed, view wire feed unit to ensure wire is being fed. If not, turn the welder “OFF” and add more tension to the wire feed adjustment spring.

17.Turn welder “ON” and press trigger. One flux-core wire is exposed, turn welder “OFF. ”

18.Slide contact tip (8) over the flux-core wire (10) and screw it into the torch end (11).

19.Replace nozzle and cut off any flux-core wire in excess of a 1/4 inch.

20.Close the cover on top of the welder.

OPERATING THE ARC WELDER

Ensure the Arc Welder is turned “OFF. ”

Ensure the work piece is free of chemicals or oily substances that may catch fire or impair the welding process.

Ground the object to be worked by attaching the grounding clamp. If the work piece is secured to a metal work bench, grounding the work bench is an accept- able alternate.

Set the Current Switch. The thicker the work piece, the higher the current.

Set the Wire Speed Control to 5. Adjust as needed.

Plug in the power cord to an approved AC outlet. If an extension cord is used, refer to the manufacturer’s instructions to ensure it is heavy enough to handle the load. If the extension cord is too light, it may become overheated and ignite.

Hold the Torch away from any grounded object. Contact with a grounded object may cause the torch to inadvertently ignite.

Turn the Arc Welder “ON.”

Test the speed of the wire feed. Adjust as necessary. Cut off excess wire so only 1/4 inch is protruding from the torch tip.

Put on welding goggles or lower welding helmet.

Ignite the arc by passing the electrode wire back and forth over the work piece.

When finished welding, lift the torch away from the work piece or any other grounded objects.

Turn the Arc Welder “OFF. ”

Unplug the AC power cord from the receptacle.

DUTY CYCLE AND THERMAL OVERLOAD OPERATION

This Arc Welder is designed to operate at the maximum duty cycle, which is a per- centage of actual weld time. For example, for a ten minute interval at 10% maximum duty cycle, the actual welding time would be one minute. The Arc Welder should then cool for nine minutes. The Arc Welder has an automatic thermal switch, which protects the internal components and accessories from overheating. If the duty cycle is exceeded the red lamp on the front of the Arc Welder will turn “ON.” Resume welding when the red lamp turns “OFF. ”
