Claim 0:
1. A method of operating an electrosurgical generator, wherein the method comprising:
generating an AC output voltage and supplying the AC output voltage to outputs of the electrosurgical generator, wherein a maximum AC output voltage value is predefined for the AC output voltage;
determining a load present at the outputs and comparing the load with a threshold value, which is defined such that a load falling below this threshold value indicates an occurrence of a vaporization phase;
wherein, as long as the load remains below the threshold value, a maximum AC output voltage value is preset such that the maximum AC output voltage value is lower than a preset maximum output voltage value that is set when the threshold value is exceeded;
controlling the AC output voltage based on the preset maximum AC output voltage value;
establishing a vapor bubble as part of a vaporization phase during an initial phase;
creating arcing as part of an ignition phase during the initial phase; and
during the initial phase, applying the maximum AC output voltage value; and
if the threshold value is exceeded, applying the preset maximum output voltage value that is higher than the maximum AC output voltage value.
