Abstract: The invention relates to a coupling device (24) used for producing a flow path between the tank (6) of a water vapor cutting device (1) and a liquid-filled cartridge (25), wherein said coupling device (24) comprises a housing (29) provided with a receiving area (30) which is formed therein, used for mounting the cartridge (25) on said housing (29) and which comprises a channel (39) provided with an input orifice (40) fluidically connectable to the cartridge (25) and to an output opening (41) which is also fluidically connectable to an external surrounding area, for example to the tank (6).

Abstract: The invention relates to a vapor plasma burner (6) comprising a burner handle (6a) and a burner base (6b). Inside the burner base (6b), a liquid feed pipe (32), a heating device (26), a burner chamber (27), a cathode (22), connected to a cathode support (28), and an anode (24) which is configured as a nozzle (23) and has an exit opening (25) are arranged. The invention also relates to a cathode (22) and to a nozzle (23) for such a vapor plasma burner (6). The aim of the invention is to provide a vapor plasma burner (6) that can be optimally ignited and the wearing parts of which can be easily removed.

Abstract: The invention relates to a method for operation of a steam plasma burner (6), comprising a cathode (22) and an anode (24) in the form of a nozzle (23) for machining a workpiece (20), wherein during the operation a current is applied between the cathode (22) and the anode (24) and/or the workpiece (20) by means of a power supply (2). After starting a pilot arc between the cathode (22) and the anode (24) by approaching the steam plasma burner (6) to the workpiece (20), a working arc is formed between the cathode (22) and the workpiece (20) and the pilot arc is extinguished by switching off the power supply (2) to the anode (24) and the current increased to a given working current. In order to achieve an optimal operation of a steam plasma burner, the voltage (UUE) between the cathode (22) and the workpiece (20) is monitored during working operation and the power supply (2) reconnected to the anode (24) to reform the pilot arc when the voltage (UUE) exceeds a threshold (IUEs).
