Microcomputer Controlled System of Scr Arc Welding Power Source

Li Heqi ( Research Institute of Welding ) Zeng Lingchun ( Department of Automatic Control ) Ma Yuezhou Sun Zhongcheng Xiao Guoming (Research Institute of Welding)  
A stable, reliable, and simple both in hardware andsoftware applied system for scr arc welding power source with microcomputer control is described in this paper. It is pointed out that the PID algorithm is such one for this aplljed system, by which both static and dynamic characteristics canbe taken into consideration. The influence of different coefficients in PID algorithm on the current wave of short-circuiting transient also discussed. The results of welding tests show that this opllied system fully meets the technological needs for MMA, TIG, ect. and it has the adran-tages of less splash, stable arc, wide adjusing range, and controlled dynamics behavior.
