PROBLEM POSSIBLE CAUSE POSSIBLE SOLUTION
Bead too thick in places Holding the electrode too long in
one place or moving it too slowly
across the base metal
Speed up; maintain a uniform rate
of speed along the bead
Ragged depressions at
edge of weld
Moving the electrode too rapidly or
holding too short an arc
Slow down; lengthen the arc
slightly
Overlapping beads Arc too long or rate of travel too
fast
Slow down
Electrode sticks to work Electrode is held in contact with
base metal while arc is struck
Move electrode away from the base
metal immediately after the arc is
struck
Poor electrode

sputter and stick
1. Damp electrodes
2. Wrong type of electrode
1. Store electrodes in a dry location
2. Use correct electrode
