| Abstract: | 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. |
