Dirty workpiece or electrode:
Clean workpiece down to bare metal.
Make certain that electrode is clean and free
from oil, coatings, and other residues.

1. Workpiece overheating:
Reduce current.
2. Welding speed too slow:
Increase welding speed and ensure
that welding speed is kept steady.
3. Excessive material at weld:
Reduce amount of fill material.
