The MMA | are compactly built for welding without protective gas ARC welding machines are among the strongest and lightest in their class. Integrated overheating protection and high-performance cooling enable continuous access to maximum performance. The latest IGBT technology ensures first-class efficiency with reduced power consumption. Most models have an IGBT double board, which keeps the welding current thermally stable through an increased switching frequency and thus enables significantly longer working cycles. An automatic voltage increase when starting the welding process ensures the best ignition results. The standard anti-stick function automatically reduces the welding current if the electrode sticks to the workpiece and prevents it from burning out. Optionally, the inverters can be expanded into a DC TIG welding machine by using a compatible Lift-TIG torch. The MMA | ARC welding is possible under almost all conditions and the lack of protective gas and the low weight make the devices easier to use on the move without much effort. The compact inverters are delivered with extensive accessories and of course in the usual STAHLWERK quality with a 7-year guarantee!
