10 Preparing the Stud Welding Gun
10.2 Setting the Welding Parameters
The spring force is, among others, dependent on the workpiece and welding ele-
ments used and their diameters.
The specifications in the following table are guidelines.
Select the applicable parameters for spring force for your workpiece.

*) The spring force to be set complies with the thickness of the insulating mat as well as its density (hardness).
With thick and dense insulating mats, the spring force should be raised due to the increasing friction between
the cupped head pin and the insulating material.
