The 400A Multi-Process Welding Machine is built for serious welders demanding power, flexibility, and reliability. Designed with advanced PWM IGBT inverter technology, this welder delivers smooth arc performance across multiple processes—including MIG (manual and synergic), gas/gasless MIG, DC TIG (Lift Arc), and Stick (MMA) welding. Equipped with a 5″ color LCD screen, users get intuitive control and visibility over weld parameters. Its 2T/4T/Spot weld settings give you freedom over welding duration and control, while the 4-roll wire drive system ensures stable and precise wire feeding every time.
