Abstract
A system and method generates a short circuit arc welding waveform output, having a pinch phase with a break point and a necking threshold, between a welding electrode and a work piece during a short circuit arc welding process. A necking threshold energy and a break point energy of the short circuit arc welding waveform output are monitored during the short circuit arc welding process, and a running average of the necking threshold energy is generated. An actual pinch energy relationship value is calculated based on the running average of the necking threshold energy and the break point energy, and is compared to a previously specified pinch energy relationship value. The break point energy of the short circuit arc welding waveform output is adjusted in response to the comparison to maintain the actual pinch energy relationship value to be at the specified pinch energy relationship value.
