Troubleshooting (continued)

Important!

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

Power switch (7a) does not light when switched on

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 amperage as detailed on the Specifications table.

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 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.
