| Abstract: | A simple, relible micro-computer controlled SCR welding rectifier hardware and it's software for gaining a multifunctionat static charicteristic and good dynamic charicter are described in this paper. Potential-Integrate-degrade(PID)control caculating method is a rather satisfactory one. Results from a series fo welding process like MMA, C02 and SMAW by this new developped rectifier indicates that it delivers the SCR rectifier advantages in reliablity, fiexbility as well as in welding productivity. |
