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.
TROUBLESHOOTING (continued)
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.
