Chicago Electric Troubleshooting MIG Welders: Solutions for Arc Issues and Wire Feed Problems

Troubleshooting (continued)

IMPORTANT!

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

Power switch lights,

but welder does not function when switched on

POSSIBLE CAUSES AND SOLUTIONS

1.Tripped thermal protection device:

Stop welding and allow welder to cool for at least 20 minutes.

Reduce duration or frequency of welding periods to help reduce wear on the welder. Refer to Duty Cycle section on page 20.

2.Faulty or improperly connected Trigger:

Qualified technician must check and secure/replace Trigger.

Power switch 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 voltage and amperage as detailed on the

Specifications table.

Make sure installed plug is correct rating (250 V~, 50 A recommended) - see page 7.

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: 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.
