1. Improper clamping:
Clamp workpieces securely.
Make tack welds to hold workpieces.
2. Excessive heat:
Weld a small portion and allow to cool
before proceeding.
Increase weld speed.
Slag is a necessary part of a stick weld. It shields
the weld from impurities. Clean off the slag with the
Chipping Hammer and Wire Brush after welding.
1. Dirty workpiece or electrode:
Clean workpiece down to bare metal.
Make certain that fill material and electrode are clean
and free from oil, coatings, and other residues.
2. Inconsistent welding speed:
Maintain steady weld speed.
1. Inaccurate welding:
Use two hands or rest hand on steady surface.
2. Inconsistent welding speed:
Maintain steady weld speed.
Fine spatter is normal. Spatter that is
grainy and large is a problem.
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.
