The Hugong – MIG/STICK 251DIII Multi-Process Inverter Welder (230 V Single-Phase, 50–250 A MIG / 30–200 A MMA) delivers industrial-grade performance in a portable design. Built with advanced IGBT inverter technology, it ensures high duty cycles and excellent welding capacity.
Equipped with a built-in 4-roll wire feeder unit, the machine provides stable wire feeding for steel, stainless steel, aluminum, and flux-cored wires. Operators benefit from digital current and voltage displays, stepless wire feed speed, voltage, and inductance adjustment for MIG welding, as well as anti-sticking, hot start, and stepless current adjustment for MMA welding.
Additional features include 2T/4T selection, European quick connectors, fan cooling, and IP21S protection class. Its compact, patented design with wheels makes it easy to move in workshops or industrial sites.
The machine is supplied with standard included accessories: a 3 m HG MIG-36 (or MB36) welding torch, a 3 m earth cable with clamp, V-groove drive rollers (0.8/1.2 mm) for solid wire, and a 2.5 m input power cable, ensuring operators have everything needed to start welding immediately.
