A welding power source controlled by Z-80 single-board microcomputer has been developed.A computer was introduced into the QH-ARC welding arc control system.Various types of desirable characteristics may be obtained by only changing the sof-tware.In this paper the hardware diagram and the features of extended interfaceswere carefully briefed,such as A/D and D/A convertors,PIO,electronic switchand some logic circuits.The design method of the gain in some blocks is given,and the effect of“converse equivalence”on system accuracy is discussed.In thenonlinear discrete control,a sampling period T=100μs is adopted.The P and PIregulation with threshold and the experimental results of constant voltage,constantcurrent and dual-step static characteristics are described.The results show that ±1bit static accuracy and satisfactory dynamic response can be obtained with the cons-tant value regulation system.This enables the power source control to be moreaccurate and versatile.Doubtlessly,this system should be n effective means of realizing the fully automatic welding process.
