1. A system for delivering electrosurgical energy, comprising:

  • an electrosurgical instrument comprising at least one electrode; and

    an electrosurgical generator coupled to the electrosurgical instrument, the electrosurgical generator comprising;

    an output stage configured to generate electrosurgical energy; and

    a controller coupled to the output stage, the controller configured to control the output stage to output electrosurgical energy at a predetermined power control mode having a first current level to generate an arc between the at least one electrode and tissue and to output electrosurgical energy at a predetermined current level control mode having a second current level different from the first current level once the arc is generated to sustain the arc.
