Stud „hangs-up“
during the weld
Plunge dampening is
too little.
If the gun is a Heavy Duty gun, it is equipped with Tranquil Arc
®
. Screw in the clear plastic
plunge dampener housing to decrease the free travel.
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.
Mechanical bind in
accessories or ferrule.
Position the foot or ferrule grip of the gun so that the stud is centered in the ferrule
opening.
If the stud is off-center, it can restrict the plunging motion of the stud during
welding.
Time setting or current
setting is too high.
Check the stud burn-off. If the burn-off is much greater 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. Correct the settings and perform
weld inspections
as described in Sections 2.7.4 and 2.7.5.
Plunge dampening is
too great.
If the gun is a Heavy Duty gun, it is equipped with Tranquil Arc
®
. Back out the clear
plastic
plunge dampener housing to increase the free travel.
Manually depress chuck adaptor and release. Chuck adaptor must return to the full out
po-
sition rapidly without binding. If necessary, disassemble and clean the gun.
On Heavy Duty guns, ensure that the weld cable is centered between the legs and does
not
rub on them.
