A high frequency surgical device for generating a high frequency voltage for cutting and/or vaporizing biological tissue within a flushing liquid, in particular a conductive flushing liquid, including two output contacts at which an electrosurgical instrument is connectable and between which the HF voltage is provided during operations; a parallel resonant circuit which is electrically connected with the output contacts and in which the HF voltage is generated during operations, and wherein the HF voltage is configured for igniting an electric arc within the flushing liquid at the electrosurgical instrument. In order to provide an electrosurgical device for applications under a flushing liquid, wherein the flushing liquid is heated less and wherein the electrosurgical device provides better initial cutting properties, it is provided according to the invention that a voltage limiter is arranged between the parallel resonant circuit and the output contacts.
