1.Excess wire feed pressure:

2.Incorrect contact tip size:

Replace with the proper tip for the wire size used.

3.Gun end not inserted into drive housing properly:

Loosen gun securing bolt and push gun end into housing just enough so that it does not touch wire feed mechanism.

Wire feeds, but arc does not ignite (MIG welding only)

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 (2E):

Verify that Contact Tip (2E) 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 (2E) 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.
