An electrosurgical instrument for use with an electrosurgical generator. The electrosurgical instrument incorporates a signal modificator having an input end electrically connected to the electrosurgical generator and an output end electrically connected to one or more electrodes of the electrosurgical instrument, where the signal modificator modifies a continuous signal from the electrosurgical generator into a pulsing signal to the one or more electrodes of the electrosurgical instrument. The signal modificator comprises a circuit for providing the pulsing signal.
