A system and method is provided which uses a power supply which receives an input signal and provides an output signal to an electrode, where the output signal generates an arc between the electrode and at least one workpiece, and the output signal has a desired output power profile. The power supply has at least an output power circuit which determines an output power of the output signal, a power differential calculator which determines a difference between the determined output power and the desired output power profile, and a waveform generator which changes a power output of the output signal based on the determined difference between the desired output power profile and the determined output power. |
