Abstract
Systems and methods for selecting a welding output waveform based on characterizing a welding circuit output path with respect to its electrical characteristics. At least one electrical characteristic (e.g., inductance, resistance) of a welding output circuit path connected to a welding power source is determined. A welding output waveform is selected from a plurality of welding output waveforms based on the determined electrical characteristics. As a result, the selected welding output waveform is matched to the welding output circuit path electrical characteristics to provide superior welding performance.
