OPERATION - STUD GUN
Y
Disconnect gun from power source
before installing or removing compo-
nents.
The stud gun automates the stud welding
process.
Several key functions are:
•
Holds the ferrule, spark shield or gas de-
livery system
•
Holds the stud
•
Strikes the arc
•
Establishes the arc length (lift distance)
•
Thru the power source, the gun controls
the arc time
•
Controls rate of plunge of the stud into
the base metal

.
Before welding it is important to review
the set up. Correct set up will produce
the best welding results. Approximately
95% of all stud welding problems are
due to improper gun set up or power set-
tings.
Welding Procedures:
•
Place stud to be welded into weld chuck.
•
Insert a ferrule into the ferrule grip (this
step is not necessary if using a spark shield)
•
Position end of stud in location to be
welded.
•
Press gun downward so the ferrule is sit-
ting on the base metal.
•
Pull trigger to begin weld sequence.
•
Hold gun still during the arcing process.
•
After weld is complete, continue to hold
the gun still for 1 second to allow the molten
metal to solidify.
•
Remove the gun from the welded stud.
Be sure and pull the gun straight off of the
welded stud to prevent damage to the weld
chuck.
•
Break away the ferrule and inspect the
weld. (Only applies if ferrule was used)
