The Ralli Wolf RT20A TIG 200 AC/DC Inverter Welding Machine is a versatile welding solution designed for professionals, fabrication workshops and industrial maintenance applications. It supports both AC and DC TIG welding, along with MMA (stick) welding, making it suitable for working with aluminium, mild steel, stainless steel, copper and other compatible alloys.

The AC welding mode is particularly useful for aluminium and aluminium-alloy applications, while DC TIG mode supports precision welding of steel and stainless steel. MOSFET inverter technology, high-frequency arc starting and pre-flow/post-flow functions help deliver controlled welding performance.

Operating on a 220V single-phase power supply, the RT20A is suitable for workshops that require multi-process welding capability without a three-phase connection.
