With the development of semicon-ductor devices, adaptation of microcontroller prevails in industrial area. But in arc welding industry, there has not been much progress in adoption of microcontroller technology. Therefore, this paper shows the application of digital control technology to welding machine.<br/> This paper presents the design of micro-controller that is appropriate for three phase CO₂gas metal arc welding machine By using microcontroller in CO₂ gas metal arc welding machine, the overall cost can be reduced compared to analog type one. Also TMS370C850 microprocessor is used as overall microcontroller for the arc welding machine.
