Abstract:
Welding systems are presented, in which a single power source provides a first DC output to a plurality of digital waveform controlled chopper modules. Welding modules are also disclosed for converting an input DC signal to a welding signal, which are comprised of a down-chopper for providing a welding signal waveform according to a pulse width modulated switching signal, along with a digital waveform controller providing the switching signal according to a desired waveform.
