The Ralli Wolf RT31A TIG 315P AC/DC Pulse Inverter Welding Machine is a professional welding solution designed for precision fabrication, aluminium welding and industrial metalworking. With AC/DC TIG welding and MMA functionality, it offers flexibility for welding aluminium, mild steel, stainless steel and other compatible metals.

Its pulse welding capability allows operators to adjust pulse frequency and pulse width for greater control over heat input and weld appearance. High-frequency arc starting, adjustable up-slope and down-slope, and post-flow control help deliver smooth, controlled welding performance.

Operating on a 415V three-phase power supply, the RT31A is suitable for fabrication workshops, pipe welding, aluminium products, pressure vessels and construction-related metalworking applications.
