The inverter versatile arc welding machine is introduced.The structure of the main circuit is made up of MOSFET and ferrite magnetic core. The core of the control circuit which is PWM and the external characteristic of constant current with inward decent have been designed. As a result, the welding power source has good static and dynamic characteristics. The analytical and experimental results show that this inverter welding machine has high reliability and the welding effect is good.
