摘要： A device for plasma welding and cutting by means of a plasma torch or burner. A first current source is provided for feeding a pilot arc discharge. The negative pole of the current source is connected to the electrode of the burner while the positive pole is connected to the nozzle of the burner. A second current source feeds the main plasma arc discharge and its negative pole is connected to the burner electrode and the positive pole to the work piece. Specifically, the current branch of the second current source which connects to the work piece is bypassed by a bypass branch in such a manner that when the plasma main arc discharge current is closed the resulting peak current is diverted through this bypass branch.
