Abstract
A method and apparatus for short circuit welding is disclosed. They reduce the current prior to the short clearing by adjusting waveform parameters in response to past cycles. One or more parameter of the output is monitored and compared to one or more targets, and future waveform parameters are adjusted so that the monitored parameters are more likely to reach the one or more targets.
