A system for controlling the operation of a high frequency biological tissue cutting device for cutting biological tissue with high-frequency current having a HF generator component designed so that the amplitude of the voltage (UG) applied to the tissue can be changed. At least one adjustment device is provided to adjust one of the characteristic values (K) of the high frequency generator component to a 1st desired value (b), related to the output of an indicator device that indicates by an electrical signal (d) the size and intensity of the electric arc occurring between the surgical probe and the tissue during cutting. A desired-value transmitter provides a second desired value (c) representing the desired size and intensity of the electric arc. An evaluation unit receives the output signal (d) of the indicator device and the 2nd desired value representing the intensity of the electric arc (c) and provides therefrom a desired value (b) output for the adjustment device such that the maximum changing speed of the desired value (b) is at least one magnitude smaller than the speed with which the adjustment device adjusts the characteristic value (K) of the high-frequency generator component.
