摘要：An electric arc welding system including a power lead for providing weldingcurrent between an advancing welding wire and a workpiece, a short circuit sensor havinga short circuit output signal when the electrode is shorted with the workpiece and apremonition sensor having a fuse output signal when a short circuit is about to break. This
welding system has at least two power source modules, each with a common isolated DCinput and an output connected to the power lead with each of the modules controlled toperform a short circuit arc welding process. The individual module comprises a regulatedDC to DC converter having a DC output signal with a waveform controlled by a waveformsignal from a controller and an output switch receiving the DC output signal and in serieswith the power lead where the output switch is opened by a gate signal to reduce thewelding current in the power lead.
