An electrosurgical system, having a solid state generator for providing a cut mode electrosurgical current waveform of RF electric energy having a first voltage amplitude to an active electrode terminal, is adapted by the addition of an apparatus for alternatively providing a fulguration mode current waveform having a second higher voltage amplitude from the generator to the active electrode terminal. A fulguration adaptor including a transformer for enabling the generator to provide a fulguration mode waveform having said second higher voltage amplitude; switching apparatus connected to the transformer for selectively connecting the transformer to the generator for providing said fulguration mode waveform, for disconnecting the transformer from the generator, and for switching off the current from the generator when operated to disconnect the transformer; and a delay circuit connected to the switching apparatus for delaying said disconnection of the transformer until after the current from the generator has been switched off.
