MMA electrode welding / ARC welding - a universal welding process. An electric arc melts the electrode to form the weld seam. No shielding gas is required and can therefore be used flexibly at any location. IGBT technology - The latest and most modern transistor technology enables high performance welding. No transformer, no mosfet, state-of-the-art IGBT. Lightweight & compact design - only 10.3 kg weight and dimensions of 455 x 220 x 370 mm. Innovative IGBT transistors save space and weight compared to the old mosfet technology. No more heavy carrying. Highest efficiency & performance - three-phase alternating current (400 V) supplies the device and allows an output power of real 270 amps. Equipped with solid 13 mm professional connection sockets, the device guarantees maximum performance.
