ADVANCED PROCESS INVERTER – MASTER M

MASTER M

Master M 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, Master M 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 Master M cooling system for an integrated liquid-cooled package that maximizes the 350A 40% ED welding power and enables more extended welding periods.
