Important!

Be CERTAIN to shut off the Welder, disconnect it from power, and discharge the torch to ground before adjusting, cleaning, or repairing the unit.

Wire Feeds, but arc does not ignite

Possible Causes and Solutions

1.Improper ground connection:

Make certain that the workpiece is contacted properly by the Ground Clamp and that the workpiece is properly cleaned near the ground clamp and the welding location.

2.Improperly sized or excessively worn Contact Tip (2b):

Verify that Contact Tip (2b) is the proper size for .030” wire (0.9 mm). Check that the hole in the tip is not deformed or enlarged. Also, check that the tip is not dirty; this would pre- vent a good connection. If needed, replace Contact Tip (2b) with proper size and type.

Weak Arc strength

Possible Causes and Solutions

1.Incorrect line voltage:

Check the line voltage and, if insufficient, have a licensed electrician remedy the situa- tion.

2.Improper gauge or length of extension cord:

Extension cords are not recommended. If possible, eliminate the use of an extension cord. If an extension cord is needed, refer to the gauge and length chart on page 10 and in relation to the required input amperage stated on the Specifications table.

If the steps above do not solve the problem or if the repairs involved are too

complex, contact a qualified technician.
