METHOD OF AND DEVICE FOR CONTACTLESS IGNITION OF AN ARC

A method and a welding device for contactlessly striking an arc between an electrode of a welding head and a material surface of a workpiece. A first ignition voltage pulse with a first or second polarity is generated between the electrode and the material surface. After being struck and, where appl...

description A method and a welding device for contactlessly striking an arc between an electrode of a welding head and a material surface of a workpiece. A first ignition voltage pulse with a first or second polarity is generated between the electrode and the material surface. After being struck and, where applicable, after a polarity reversal, the arc is maintained with the second polarity or with an alternating polarity. In the event of an ignition failure, after the first ignition voltage pulse, a sequence of ignition voltage pulses is generated according to a sequence pattern until successful striking of the arc. The sequence pattern includes ignition voltage pulses with the first polarity and ignition voltage pulses with the second polarity, and an ignition pause is provided between ignition voltage pulses with the first polarity and ignition voltage pulses with the second polarity.
