Problem
Possible Cause
Solution
Weld appears “cold”
Time setting or current
setting is too low.
Check the stud burn-off. If the burn-off is much less than what is typical for that
diameter stud, the time and current settings may not be correct. Consult Section 2.6
to ensure proper current and time settings are being used.
Incorrect ferrule.
Ensure that the ferrule being used in the welding process is the proper ferrule for
the stud size and application.
Inconsistent gun lift.
Perform a Lift Check, as specified in Section 4.5.14. Consult Section 2.6 to ensure
proper lift settings are being used. Correct the lift to the proper setting if the lift is
improperly set.

Inconsistent gun lift.
Perform a Lift Check, as specified in Section 4.5.14, several times. Consult Section
2.6 to en- sure proper lift settings are being used. If lift results are inconsistent,
disassemble and clean the gun.
Too much plunge.
Plunge is measured by the amount of stud protruding beyond the bottom edge of the
ferrule. Consult Section 2.6 to ensure proper plunge settings are being used, and
correct, if necessary.
