    • Abstract
  • To meet the demand of improving welding productivity through increasing welding current for high efficiency welding, the method based on parallel connecting of inverter power for pulsed MIG welding is presented. A DSP based digital control system for high-power pulsed MIG welding is introduced, which is based on digital signal processor TMS320LF2407A. By taking advantage of rich peripherals and excellent control performance of DSP, the goal that a single DSP control two inverters was realized, which ensured the high-power output of welding power. The results show that the developed parallel high-power inverter power for pulsed MIG welding has the ability to accomplish the high efficiency welding process with high current output, and the welding performance is stable, the appearance of weld is good.
