Claim Text:
1. An arc welding power supply configured to output a welding waveform to a welding torch, the welding power supply comprising: a waveform generator to generate an output welding waveform; and a controller to optimize the output welding waveform based on one of a desired RMS voltage set point and a desired RMS voltage range, where said one of said desired RMS voltage set point and said desired RMS voltage range is utilized to reach a desired heat input for a welding operation where said desired heat input is determined by said controller based on user input information, wherein the optimization of the output welding waveform optimizes the heat input and is performed by adjusting at least one of a power ratio and a duration ratio, wherein the power ratio is a ratio of a power of a negative portion of the welding waveform to a power of a positive portion of the welding waveform, and wherein the duration ratio is a duration of a negative portion of the welding waveform to a duration of a positive portion of the welding waveform.
