Diode based power sources are the basic type arc welding power source used for MMA/TIG applications. Current control is achieved through saturable core reactor. Very reliable power source but not recommended for radiographic welding application as there is no dependable feedback for maintaining the output current constant due to fluctuation of input supply or change in load. Power factor is poor for these power sources.
