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 (51b):
Verify that Contact Tip (51b) is the proper size for the welding wire used. Check that the
hole in the tip is not deformed or enlarged. Also, check that the tip is not dirty; this would
prevent a good connection. If needed, replace Contact Tip (51b) with proper size and
type.
