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.

Welder does not function when switched on

Possible Causes and Solutions

1.Tripped thermal protection device:

Shut the welder’s switch to off and allow it 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 17.

2.Faulty or improperly connected Switch Body (15e):

Have a technician check and secure/replace Switch Body (15e).

3.Internal fuse blown:

Have a qualified technician check/replace.

Weak Arc strength

Possible Cause and Solution

Incorrect line voltage:

Check the line voltage and, if insufficient, have a licensed electrician remedy the situ- ation.

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 (15g):

Verify that Contact Tip (15g) 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 (15g) with proper size and type.

If the steps above do not solve the problem or if the repairs involved are too

complex, contact a qualified technician.
