| Abstract: | The energy-storage type CO2 semiautomatic welding system is set up by adopting lead-acid battery as welding power supply.The self-regulation process of welding arc is analyzed when lead-acid battery is used as level characteristics power supply in cooperation with uniform wire-feed.Constant-speed wire-feeding process and welding specification are regulated by speed regulation system composed of PWM controller.The direct current reactor is used in order to obtain favorable dynamic property and attain the request of short-circuiting transfer to welding power supply,which makes the welding machine obtain excellent welding performance. |
