An electrosurgical generator includes one or more radio frequency (RF) so urces (60) and an output stage including at least two output lines (6OC, 48, 49, 50) for connection to an electrosurgical instrument. The generator incl udes means for measuring a parameter associated with the electrosurgical pro cedure, such as the impedance measured across two of the output lines. A con troller (72) controls the generator such that it delivers a first RF wavefor m (such as a cutting signal) or a second RF waveform (such as a coagulating signal) to the output lines, and, in a combined mode, both first and second waveforms. The controller (72) automatically adjusts at least one aspect of one or both waveforms in the combined mode, in response to the measured para meter associated with the surgical procedure.
