【Abstract】 Taking IGBT as a power converting device for main controlling switch in main circuit and high performance 16 bit monolithic computer 80C196KC as a controller, a microcomputer controlled inverter for pulsed MIG/MAG arc weldng is developed in order to achieve accurate real time control, and the reliability and anti interference design is also conducted. The investigation result shows that the pulse frequency band of this welding equipment is wide(0.5 up to 250 Hz), the response is fast, and the ability of anti interference is strong, so that the requirement of all orientation welding can be met更多还原
