Selecting the Proper Stud Collet (Stud Holder)
Listed below are the common collet styles, the choice between these setups is usually a matter of per-
sonal preference
1. The B collet which is a two
-
piece assembly (collet and insert). The insert determines how much of
the stud is engaged in the collet.
2. The CI (Collet Insert) which is a single part and the amount of the stud that is engaged is predeter-
mined.
3. Standard Adjustable Chucks have an adjustable internal screw to manually adjust for the engage-
ment of the stud.
The collet sizes are based on the diameter of the stud to be welded.
CD Stud Gun Setup
1. Place the collet into the collet
adapter of the stud gun and set the
locking screws to hold the collet in
place.
2. Mount the two legs and foot piece
onto the stud gun. The collet
should be centered through the
opening of the foot piece.
3. Insert the stud to be welded into
the collet.
4. Adjust the leg and foot piece by sliding it into position until approximately 1/8” of the stud pro-
trudes from beyond the foot piece. Lock legs in place with the set screws.
5. The tension setting is adjusted by turning the adjustment cap on the back of the stud gun. On the
side of the stud gun is the tension setting indicator, this displays the tension setting of the internal
spring.
6. The spring tension setting of the stud gun will vary depending on the application. Generally, mild
steel and stainless steel should be set in the 1 to 2 range. Aluminum and other nonferrous metals
will require settings in the 3 to 5 range.
