The Ralli Wolf RT50 TIG 500IJ is a heavy-duty DC inverter welding machine designed for high-current industrial welding and demanding fabrication applications. Powered by IGBT inverter technology, it provides an adjustable output current range of 10–500A for TIG and MMA welding operations.

The machine features high-frequency ignition for reliable arc starting, adjustable up-slope and down-slope controls, and gas pre-flow and post-flow functions to support controlled welding and protect the tungsten electrode. Its MMA facility provides additional flexibility for stick welding applications.

Operating on a 415V three-phase power supply, the RT50 is suitable for heavy fabrication workshops, pipe welding, pressure vessel manufacturing, structural steelwork and industrial production environments.
