The capacitor discharge stud welding process with tip ignition serves for welding mainly pencil-shaped metal parts from about 1 to 10 mm in diameter to thin sheets from 0.5 to about 3 mm.

Distinction is made between two processes: contact welding and gap welding.

The drawn arc welding process with tip ignition serves for welding mainly pencil-shaped metal parts from 3 to 30 mm in diameter to metal workpieces from a thickness of 0.8 mm upwards. Distinction is made between two processes: short cycle drawn arc welding and drawn arc welding with ceramic ferrule or shielding gas.
