Possible Causes and Solutions

1.Workpiece overheating: Reduce wire feed speed. Use MIN setting.

2.Welding speed too slow:

Increase welding speed and ensure that welding speed is kept steady.

3.Excessive material at weld: Reduce wire feed speed.

Weld Not Adhering Properly

Gaps present between weld and previous bead or between weld and workpiece. See areas below.

Possible Causes and Solutions

1.Incorrect welding technique: Maintain 1/2” or less stickout.

Keep arc on leading edge of weld puddle. Hold gun at proper angles.

2.Insufficient weld heat:

Reduce welding speed. Use MAX setting.

3.Workpieces too thick/close:

Bevel thick workpieces, allow slight gap, and weld in several passes.

4.Insufficient weld material:

Increase wire feed speed.
