Verify the voltage at the outlet and the connection to the outlet.

determine and remedy cause before resetting. Verify that the circuit is designed to supply

POSSIBLE cAUSES And SOLUtIOnS
Improper ground connection: 1.
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.
Improperly sized or excessively worn contact tip (2b): 2.
Verify that Contact Tip (2b) is the proper size for the wire. 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 (2b) with proper size and type.
