The Ralli Wolf RT25 TIG 250A is a compact, three-phase DC inverter welding machine designed for light and medium fabrication applications. It combines TIG and MMA welding functions in a single unit, providing flexibility for precision welding and general metalworking tasks.
Featuring MOSFET inverter technology and high-frequency ignition, the RT25 supports reliable arc starting and stable welding performance. Its gas post-flow function helps protect the tungsten electrode and weld area after welding, while the arc-force facility supports MMA welding performance.
Operating on a 415V three-phase power supply, this machine is suitable for fabrication workshops, pipe welding, pressure vessel work, construction and industrial maintenance.
