Setting the Stud Welding Pistol

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”).
