Description Of The Stud Chuck; Non-Adjustable Stud Chucks - Soyer BMS-9 Operating Instructions Manual

9 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.
Please consult the technical data for the gun to ascertain the gun type that may be
operated with a non-adjustable and/or an adjustable stud chuck.
9.1 Non-adjustable stud chucks
Non-adjustable stud chucks, as opposed to adjustable stud chucks, do not have to be
set to the length of the weld stud.
Some SOYER® welding guns can be operated with non-adjustable stud chucks.
Correct application and triggering of the stud welding gun with weld stud is monitored
by a safety switch in the stud welding gun. The welding process cannot be triggered
when there is no stud in the stud chuck.
The installation of the stud chuck is shown using the example of the PS-9 gun. The
installation of the stud chuck into other gun types is carried out in the same way.
