ExCESS OR BURN-THROUGH
Weld droops on top and
underneath, or falls through
entirely, making a hole.
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.
Cross
seCtIon
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. 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.
