A power supply for use with resistively-heated surgical instruments is provided, wherein the desired operating conditions of the surgical instrument are determined by a set-point determination circuit in combination with a set-point indicator element. The power supply includes an impedance matching circuit and current step-up transformer for reducing power loss in the cable connecting the surgical instrument to the power supply. A method of regulating the output of a power supply used with resistively-heated surgical instruments is also provided.
