In this paper, the designing approach of a spot welding machinewith a ADuC812 MCU and a improved Fuzzy-control algorithm is introduced. The measuring circuit for RMS of non-Sin welding current and the precise triggers of SCR using interrupt controllers and timers in AduC812 MCU are also described. According to the characteristics and technology demand of the welding process, the variable framework, Fuzzy-control algorithm, and a controlling strategy with forecasting initiative values are adopted. The experiments show the designing successful.
