Possible Causes and Solutions
1.Excessive material at weld: Reduce wire feed speed.
2.Overheating:
Increase welding speed and ensure that welding speed is kept steady.
Weld Not Adhering Properly
Gaps present between weld and previous bead or between weld and workpiece. See areas below.

Possible Causes and Solutions
1.Dirty workpiece:
Make certain that workpiece is clean and free from oil, coatings, and other resi- dues.
2.Insufficient weld material: Increase wire feed speed.
3.Incorrect welding technique:
Place stringer bead at correct place in joint.
Adjust workpiece position or weld angle to permit proper welding to bottom of piece. Pause briefly at sides when using a weave bead.
Keep arc on leading edge of weld puddle.
Hold gun at proper angles as stated under Holding The Torch on page 17.
Possible Causes and Solutions
1.Workpieces too thick/close:
Joint design must allow weld to reach bot- tom of groove and allow proper welding procedures.
2.Incorrect welding technique: Maintain 1/2” or less stickout.
Keep arc on leading edge of weld pud- dle.
Hold gun at proper angles as stated under Holding The Torch on page 17.
3.Insufficient weld material: Increase wire feed speed.
4.Insufficient weld heat: Reduce Welding Speed.
Bend at joint

Possible Causes and Solutions
1.Improper clamping:
Make sure that pieces are clamped se- curely in place.
Make tack welds to help hold pieces.
2.Excessive heat:
Weld a small portion and allow to cool before proceeding.
Reduce wire feed speed. Increase weld speed.
