POSSIBLE CAUSES AND SOLUTIONS
Unit is not connected to outlet properly or outlet is unpowered:
Verify the voltage at the outlet and the connection to the outlet.
If voltage is not present at outlet, check circuit breaker/GFCI devices; if any are tripped, determine and remedy
cause before resetting.
Verify that the circuit is designed to supply the required input voltage and amperage as detailed on the
Specifications table.
Make sure installed plug is correct rating (250 V~, 50 A recommended) - see page 7.

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:
Verify that Contact Tip is the proper size for welding 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 with proper size and type.
