Contamination of the base plate or stud may cause the arc to become erratic. Ensure that
the-
re is no rust, scale, oil, water, residue, paint, galvanization, etc. present between the
stud and
the work piece. Welding to a clean plate can help diagnose if there is any
foreign substance
on the base material or studs.
