A chamber (24a) is provided for enclosing the cutting beam from its outlet from the nozzle till to its striking on a workpiece (22), where the chamber thermodynamically and/or flow-mechanically influences the cutting beam. The chamber is made from elastic material, where an end of the chamber is provided with a sealing device.de620patent102011116228
