ABSTRACT:
In plasma/water cutting, in order to reduce the space required, it is suggested to construct the thermal cutting jet device so that water, required particularly to constrict the plasma jet, is removed by means of an annular suction nozzle or a ring of annular suction bores arranged around the thermal cutting jet device. In order to reduce the resulting noise, a spraying device can be arranged around the annular suction nozzle whose water is fed back to a tank either by a suction device for the cutting jet device, or by an additional suction device.
