摘要：An electric arc welding system for creating an AC welding arc between anelectrode and a workpiece wherein the system comprises a first controller for a firstpower supply to cause the first power supply to create an AC current between theelectrode and workpiece by generating a switch signal or command with polarity
reversing switching points in the first controller, with the first controller operated at firstwelding parameters in response to first power supply specific parameter signals to thefirst controller. The system has at least one slave controller for operating a slave powersupply to create an AC current between the electrode and workpiece by reversingpolarity of the AC current at switching points where the slave controller is operated atsecond welding parameters in response to second power supply specific parametersignals to the slave controller. An information network connected to the first controllerand the slave controller and containing digital first and second power supply specificparameter signals for the first controller and the slave controller and a digital interfaceconnects the first controller with the slave controller to control the switching points ofsaid second power supply by the switch signal or command from the first controller.
