PARTIALLY CHIPPED AWAY TO SHOW WELD
Burn-Through
Base material melts away,
leaving a hole in the weld.
POSSIBLE CAUSES AND SOLUTIONS
1. Workpiece overheating:
Reduce current and/or wire feed speed.
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.

Porosity
Small cavities or holes in the bead.
POSSIBLE CAUSES AND SOLUTIONS
1. Dirty workpiece or welding wire:
Clean workpiece down to bare metal.
Make certain that wire is clean and free
from oil, coatings, and other residues.
2. Inconsistent welding speed:
Maintain steady weld speed.
3. Stickout too long:
Reduce stickout.

Excessive Spatter
Fine spatter is normal.
Spatter that is grainy and large is a problem.
POSSIBLE CAUSES AND SOLUTIONS
1. Dirty workpiece or welding wire:
Clean workpiece down to bare metal.
Make certain that wire is clean and free
from oil, coatings, and other residues.
2. Wire feeding too fast:
Reduce wire feed speed.
3. Stickout too long:
Reduce stickout.
