It can prestore 50 groups of welding specifications, and allows arbitrary modification and calling. Large LCD display with Chinese and English interface display, welding parameters can be easily adjusted through simple buttons.The device adopts constant voltage control, constant current control, and a mixed control mode of constant voltage and constant current, with real-time monitoring of welding current to ensure stable welding quality. The device is equipped with a current ramp-up/ramp-down function to prevent spatter during welding and meet the requirements of special material welding. It has a counting function, which can count the number of welding times to help understand work efficiency. The welding time is adjustable.
