POSSIBLE CAUSE COURSE OF ACTION
Check and secure work connection
Adjust current.
Adjust current.
Reduce arc length.
Use dry electrode.
Remove all grease, oil, moisture, rust, paint, coatings, slag,
and dirt from work surface before welding.
Decrease amperage or select larger electrode.
Reduce arc length or voltage.
Increase amperage. Select larger electrode and increase
amperage.
Place stringer bead in proper location at joint during welding.

Momentarily hold arc on groove side walls when using
weaving technique.
Keep arc on leading edge of weld puddle.
Remove all grease, oil, moisture, rust, paint, coatings, slag,
and dirt from work surface before welding.
Material too thick. Joint preparation and design must pro-
vide access to bottom of groove.
Keep arc on leading edge of weld puddle.
Increase amperage. Select larger electrode and increase
amperage.
Reduce travel speed.
Select lower amperage. Use smaller electrode.
Increase or maintain steady travel speed.
