The Ralli Wolf RT20 TIG 200A DC Inverter Welding Machine is a compact and portable welding solution designed for professional welders, fabrication workshops and maintenance applications. It combines DC TIG welding and MMA (manual metal arc) welding in one machine, offering flexibility for a variety of metalworking tasks.

Featuring MOSFET inverter technology and high-frequency arc starting, the RT20 is designed to provide stable arc performance and controlled welding output. Its post-flow function helps protect the tungsten electrode and weld area after welding, while the compact design makes the machine convenient to transport between workshops and job sites.

Operating on a 220V single-phase power supply, the RT20 is suitable for welding mild steel, carbon steel, stainless steel, copper and compatible alloys.
