Abstract
A system and method for controlling a weld-current in an arc welding apparatus involves programming of a waveform generator to supply a control signal to a weld-current power supply, the control signal being derived from a reference waveform consisting of selected segments having fixed or predetermined amplitudes and variable durations. The reference waveform may be dynamically adjusted in response to changes in welding conditions by feeding the output of an arc current and/or voltage detector back to the waveform generator and varying the duration of selected predetermined amplitude segments.
