1. An electrosurgical generator for use with a patient comprisingfirst and second electrical power generating means;

  • a common output circuit connected to said first and second electrical power generating means, said common output circuit including (a) an active lead and an active electrode connected thereto and (b) a patient lead and a patient electrode connected thereto;

    said first electrical power generating means (a) producing a voltage on said active electrode, the magnitude of which is sufficiently high to permit arcing from the active electrode to said patient and (b) including current limiting means for limiting the current through said patient to an arcing only value at which desiccation of the patient'"'"'s tissue is not likely when said active electrode contacts the patient'"'"'s tissue; and

    said second electrical power generating means (a) producing a current through said patient, the magnitude of which is sufficiently high to permit desiccation of the patient'"'"'s tissue when said active electrode contacts the patient'"'"'s tissue and (b) including voltage limiting means for limiting the voltage on said active electrode to a desiccate only value at which arcing from the active electrode to said patient is not likely.
