11. Description of the stud chuck
In principle, every welding gun is provided with a stud chuck that matches the
welding stud. There are two types of stud chucks:
• Adjustable stud chucks
• Non-adjustable stud chucks
Corresponding to the stud diameter, stud chucks must be installed/changed in the
gun.
In addition, adjustable stud chucks must be set to the stud length.
Only guns with adjustable stud chucks are described in these instructions.
11.1 Adjusting adjustable stud chucks
Adjustable stud chucks must be adjusted to the length of the welding stud and, if
necessary, to the gun size.
The standard stud chuck can hold studs with a length of up to 35 mm.

For welding guns with a short housing
(e.g. PS-1K or PS-0K), it may be necessary
to shorten the stop screw of longer welding
studs.
When the adjusting screw is too long, the stud
chuck cannot be fully plugged into the gun or
the stud lift cannot be properly executed dur-
ing welding.
Adjusting an adjustable stud chuck
Step 1:
Select the stud chuck according to the required stud diameter.
Step 2:
Insert the stud into the stud chuck.
