Patent number: 7965925Abstract: The invention describes a method for transforming a liquid (8) into a gaseous state for a cutting process with a water-steam cutting device (1), consisting of a torch (6), an evaporator (25), an energy supply and a supply line (31) for a liquid (8), an appropriate temperature (27) being generated for evaporation of the liquid (8). To create a method of this type it is now provided that the temperature (27) is regulated during operation such that a sensor (28) senses the temperature (27) of the evaporator (25) and transmits it to a regulation unit which correspondingly supplies a heating element (24) with the energy necessary and by which a required pressure (34) of the liquid (8) supplied to the torch (6) is regulated so that an approximately constant temperature (27) of the evaporated liquid (8) is provided for a cutting process.Type: GrantFiled: August 30, 2006Date of Patent: June 21, 2011Assignee: FRONIUS International GmbHInventors: Alexander Eder, Heribert Pauser, Florian Silbermayr, Alexander Speigner

Publication number: 20090266799Abstract: 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).Type: ApplicationFiled: September 6, 2006Publication date: October 29, 2009Inventors: Heribert Pauser, Alexander Speigner, Andreas Starzengruber, Max Stöger
