4.3 Setting the spring pressure
The pressure with which the stud is pressed onto the workpiece during the
welding process is referred to as spring pressure.
The following diagram displays the spring pressure setting for the Stud Welding
Pistol PS-1 with spring pressure display. The Stud Welding Pistol PS-3K is
equipped with a similar spring pressure display. The Stud Welding Pistols PS-
0K and PS-1K do not display the spring pressure.
1 Setting screw
2 Spring pressure display
The spring pressure can be set on all Stud Welding Pistols described using the
same setting screw (1). The spring pressure setting is displayed on the spring
pressure scale (2). The spring pressure is set as follows:
• Turn setting screw (1) to the left until it stops
Display position 1 = low pressure
• Turn setting screw (1) by 3.5 rotations to the right
Display position 2 = medium pressure
• Turn setting screw (1) to the right until it stops
Display position 3 = high pressure
The spring pressure setting depends on the quality of the welding stud and of
the workpiece.
Carry out welding samples and tests before starting work to determine an
optimum setting.
Samples should be taken several times during production to ensure that
equally good welding results are achieved throughout the whole production
process (see DVS Directive 0905, part 2 “How to ensure the quality of stud
welding joints”).
