SHORT CIRCUIT‐
CHECK GUN LIFT SET‐

detected for at least 100ms,

Check the gun lift setting. Under normal
welding conditions, this should not hap‐
pen.

WELD FAILED –OUT
OF TOLERANCE
The last weld was out of to‐
lerance from the target weld
by weld energy or drop ti‐
me.
Compare actual time, current, voltage, and
drop time to find cause. A new target can
also be set.
‐See troubleshooting‐
The stud is expected to hit
the workpiece after the gun
coil is de‐energized, but be‐
fore the main current is tur‐
ned off. If it is not detected,
this error will occur.
Incorrect weld parameter setup. Check
drop time, weld time, and plunge time.
Press LOCK button to clear error.
