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 Master M 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 Master M compact MIG welder models.

Integrated digital connectivity opens a world of welding data through Master M, including three months free trial for WeldEye welding management software’s ArcVision module, plus a digital WPS (dWPS) feature. Together, these welding quality management tools deliver the benefits of digital transformation to the very heart of the welding workplace.
