With the rapid development of power electronic technology and intelligent control technology applied in the field of welding, the welding machine control system has been transformed from analog to digital or intelligent direction. The core of the digital welding machine and power source are introduced in this paper. A number of researches status of domestic and foreign arc welding was elabora-ted,the advantages and disadvantages of digital arc welding power source and analog power source were compared. Principle and con-trol method of all kinds of arc welding power source was analyzed. The problems existing in current digital arc welding power supply technology were summed up,and its development foreground was prospected.
