A device with a plasma torch with a rod-shaped non-consumable electrode which is held in a receiver, is connected with an electric connection and penetrates a nozzle which is in connection with a gas connection. In order to also enable the rapid and secure welding of difficult alloys it is provided that a further rod-shaped non-consumable electrode is disposed in the receiver which is made from an electrically non-conducting material, which further electrode also penetrates a nozzle which is in connection with a gas connection, with the two electrodes enclosing an acute angle and each being in connection with a separate voltage source supplying direct voltage pulses, the level of which exceeds at least the arc voltage of an arc between one of the electrodes and a counterelectrode which is associated with the same and connected with the same voltage source.
