Availability:Out of stock

The Ralli Wolf RT20P TIG 200P Pulse DC Inverter Welding Machine is designed for precision welding, light and medium fabrication, decorative metalwork and industrial maintenance. It combines high-frequency DC TIG welding with MMA (stick) welding, providing versatility for a variety of workshop applications.

Its pulse TIG function offers adjustment of pulse frequency, base current and peak current, helping welders control heat input and achieve consistent weld results. The adjustable down-slope function supports controlled weld finishing, while the digital meter allows users to preset and monitor welding current.

Operating on a 220V single-phase power supply, the RT20P is a practical option for professional welders and fabrication workshops requiring pulse welding capability in a compact inverter machine.
