Designed and manufactured in Finland, MasterMig is a premium and compact MIG/MAG welding machine with synergic and pulse MIG welding model options. It elevates industrial welding performance, ensuring outstanding welding quality. Designed with professional welders, MasterMig makes everyday welding tasks effortless and fast.

Digital arc control, fast set-up techniques, and excellent power-to-weight set new standards for weld quality and work-based efficiency, boosting welding production. Choose from three class-leading models in the compact MIG welding machine category (353, 355, or 358), featuring alternative manual, synergic (Auto), and pulse (Auto Pulse) welding options. Weld with gas-cooled guns or select the optional MasterMig cooling system for an integrated liquid-cooled package that maximizes the 350A 40% ED welding power and enables more extended welding periods.

Experience new levels of welding productivity and control by switching on to MAX arc performance welding processes. They boost welding performance in challenging steel, stainless steel, and aluminum welding applications, making the seemingly impossible possible.

The integrated and self-charging LED work lights improve worksite safety, efficiency, and convenience. The LED light source operates with or without mains power, enhancing productivity in low light conditions. The LED work light system is standard for all MasterMig compact MIG welder models.
