Adjustment of spring pressure
The pressure with which the stud is pressed against the workpiece during the
welding proce ss is called spring pressure.
The following illustration shows how to adjust the spring pressure of stud
welding gun which is equipped with a spring pressure indicator.
The spring pressure is adjusted by means of the adjusting screw (1).
The adjusted pressure is indicated at the spring pre ssure scale (2).
Adjust spring pressure as follows:
* Turn adjusting screw (1) to the left until stop
Indicator position 1 = low pressure
* Turn adjusting screw (1) 3.5 turns to the right
Indicator position 2 = medium p ressure
* Turn adjusting screw (1) to the right until stop
Indicator position 3 = high pressure
The spring p ressure to be adjusted depends on the material of both welding
stud and workpiece.
Before starting the work, carry out some experimental weldings and test them
to find out the optimum adjustment.
