Disclosed is an ignition system for initiating a plasma arc in an electrosurgical system. The system includes a source of high frequency electrical energy having a terminal of active potential and a terminal of return potential a base having a distal end from which a plasma arc emanates, an active electrode operatively coupled with the base and electrically in circuit with the terminal of active potential. The ignition system may have a piezoelectric device electrically coupled to the active electrode to create at least one high voltage spark when the system is initially activated. Alternately, the ignition system may include a heater or heating device of heating the active electrode and producing free electrons to assist in the initiation of the plasma arc.
