摘要
In order to be able to detect a possible cut during the thermal separation of a workpiece already during the separation, according to the invention a method is proposed for detecting an imminent or completed cut, in which an energy input occurs in a cutting area, and the following method steps comprise: a) applying b) detecting a second alternating signal produced by the first alternating signal in a measuring electrode spaced from the workpiece, c) determining the phase shift between the first and second alternating signals by outputting a phase shift signal, d) comparing the phase shift signal with a predetermined upper one Limit and a predetermined lower limit for the phase shift signal wherein when the phase shift signal exceeds the upper limit or the lower limit, the energy input is changed, at For example, by the thermal separation of the workpiece is stopped.
