SELECTING THE PROPER STUD COLLET (STUD HOLDER)
The collet is selected to the proper diameter that you are welding.
There are three styles of collets;
• The “B” collet which is a two‐piece assembly (collet and insert). The insert deter‐
mines how much of the stud is engaged in the collet.
• The CI (Collet Insert) which is a single part and the amount of the stud that is en‐
gaged is predetermined.
• Standard Adjustable Chucks have an adjustable internal screw to manually adjust
for the engagement of the stud.
The choice between these systems is usually a matter of personal preference.
Inserting the selected collet into the stud gun is a simple task. Place the collet into
the front holder of the stud gun and set the locking screws to hold it in place.
After inserting the collet, mount the two legs and foot piece onto the stud gun. The
collet should be centered through the opening of the foot piece.
When the legs and foot piece are in place, insert the stud to be welded into the col‐
let. Adjust the leg and foot piece by sliding it into position until approximately 1/8”
of the stud protrudes from beyond the foot piece. Lock legs in place with the set
screws.
