During the actual welding process, you must expect red-hot welding
spatters, possibly liquid spatters, a flash, and a loud bang may occur
> 90dB (A). Inform any collegues who are occupied in the vicinity of
the welder about the bang.
Wear always your personal protective equipment according to actual
standards (see appendix).
Insert the welding element into the chuck.
As soon as the power unit is ready for the welding process,
place the welding gun vertically against the workpiece,
push the welding gun firmly with both hands onto the workpiece until the welding
gun support (distance device) is evenly seated on the workpiece,
hold the welding gun firmly, still, and straight,
take care that you do not touch any metallic part of the welding gun,
press the trigger button of the welding gun.
This initiates the welding process.
The welding process can only be initiated, if the current circuit
is closed, i.e. the welding element is in electrical contact with
the base material.
After the welding process has been completed, withdraw the
welding gun straight back from the welding element. If you
remove the welding gun at an angle, the chuck will be stret-
ched, this reduces its life expectancy.
You can now insert a new welding element in the chuck and repeat the welding process
as described above.
5.8 Checking the Quality of the Weld
You can check the quality of the weld by means of a visual inspection and a bending
test.
See also actual standards in the appendix “Arc stud welding of
metallic materials“, in section irregularities and corrective
actions.
