The capacitor battery will be charged according to chosen charging voltage.
The
stud (with ignition tip) is placed onto the work piece and pressed by a
spring in the welding gun onto the work piece (contact). The current
circuit is closed.
After triggering the welding process, the rapidly increasing current evaporates the ignition tip and ignites the arc.
Stud and work piece are melted.
The stud is moved forward to the plate.
The arc is cut as soon as the stud touches the work piece.
The molten zones are joining and solidifying.
Welding time is ≤ 3 msec.
Recommended plate thickness should be 1/10 d, but not less than 0.5 mm.
