Systems and methods for controlling an output power of a welding power supply

Abstract:

A method for controlling an output current of a welding power supply includes detecting, using control circuitry of the welding power supply, a root mean square (RMS) current setting. The method also includes calculating, using the control circuitry, an average current command based on the RMS current setting. The method also includes controlling, using the control circuitry, the output current using the average current command to produce an output substantially the same as the RMS current setting.
