The lift controls the arc length and is a factor in controlling the heat of the welding process.
Lift should be set at 3/32 or .094 in (2.5 mm).

YFor safety from accidental activation, always disconnect the weld cable from the power source before making any stud gun adjustments or per- forming any service on the stud gun.

To adjust lift, remove the slotted screw hold- ing the rear cap in place. Remove rear cap. Loosen the nylon tipped set screw that holds the adjustable core in place. To increase lift, turn the adjustable core screw counter clockwise. To decrease lift, turn the adjust- able core screw clockwise. Each half turn equals .025 in (0.6 mm).
Once lift is set, retighten nylon tipped set screw to keep the adjustable core in place.
Install rear cap and tighten cap screw.
