A CO 2 welding power source of IGBT inverter type controlled by the single chip microcomputer 80C196KB is introduced. The structure of main circuit of this power source, the basic working principle of the microcomputer hardware system, the design of the software and the welding process experiment are described. The result of welding process experiment shows that this power source is successful in controlling accurately the output of constant voltage and constant wire feed speed. More over, the controlling system is satisfactory in stabilizing the arc, decreasing spatter, with simple and reliable circuit, and is of high practical value.
