When it does become necessary to adjust the lift,
you do so by removing the rear cap from the gun.
This will expose the rear coil choke assembly, the
set screw, and the lift adjusting screw (Refer to Fig-
ure 6-2).
Loosen the set screw.
To increase lift: turn the adjusting screw out
(counter clockwise).
To decrease lift: turn the lift adjusting screw in
(clockwise).
Once the lift has been set, tighten the set screw and
replace the rear cap.

5. Make sure that the cables are connected to the
power source (standard set-up is straight polarity –
Negative to controller, or gun, and Positive, ground ca-
ble, to work surface).
6. Turn on the power supply and adjust the current and
time for the weld base diameter of the fastener to be
welded.
7. Place the gun, loaded with the stud and ferrule,
squarely against the ground work surface. The main
spring in the gun will take up the “plunge length” and
the ferrule will seat against the base plate.
8. Pull the trigger holding the gun completely still as
above. The gun will lift the stud from the base plate
and draw an arc. The end of the stud and the adjacent
metal of the base plate will be melted by the weld arc.
The gun will then plunge the stud into the molten pool,
extinguishing the arc, to end the controlled portion of
the weld cycle
.DO NOT MOVE THE GUN DURING THE WELD
CYCLE.
9. After the controlled weld cycle, allow the molten
metal to solidify briefly with the work surface to assure
completion of the cycle (about an extra second holding
“still” after the weld is usually sufficient).
10. Remove the gun from the work by lifting straight
away from the welded stud (this will assure better life
to the gun’s expendable accessories). The ferrule may
now be removed by breaking it away from the welded
stud to allow inspection of the weld results. After in-
spection of sample welds the gun can be adjusted, as
per the steps in this procedure, for optimum results
