Fault Possible Cause Remedies
Single sided weld has a nice
appearance but is not consistent.
Excessive sparks when welding
with pincer gun.
Incorrect settings.
Poor location of ground shoe.
Heavy zinc coating of sheets.
Poor quality welding primer.
Insufficient effort of electrodes.
Reduce welding time and increase welding power.
Make sure ground shoe is close to spot of weld and that it
is on bottom sheet and not on sheet where weld is to be
applied. Check temperature of sheet between spot of weld
and ground shoe. An elevation of temperature of approxi-
mately 40° F after 4 spots indicates a bad return of cur-
rent.
Use setting for welding of zinc coated sheet. If necessary,
remove some of zinc.
Use Saitek Z-Coat primer.
Increase air pressure (70PSI minimum with short arms).
