The Ralli Wolf RT20A (TIG 200 AC/DC) is a light and compact TIG welding machine that combines AC/DC TIG and MMA welding functions in a single, easy-to-carry unit. With high frequency ignition, superior arc performance, and a post-flow function, it delivers clean, stable welds while economising tungsten use through its stable output and high duty cycle. The AC/DC capability makes it suitable for welding both aluminium and steel/stainless steel from the same machine. Running on a single-phase 220V supply, the RT20A is ideal for workshops and professionals who need reliable, versatile welding without the bulk of larger 3-phase machines. Backed by Ralli Wolf Industries Ltd. (formerly Ralli Engineering Ltd.) and its ISO 9001:2015 certified manufacturing, the RT20A comes complete with standard TIG and MMA accessories, ready to use out of the box.
