The Ralli Wolf RA50 ARC 500IJ is a heavy-duty IGBT inverter welding machine designed for industrial welding, steel fabrication, and demanding metalworking applications. With a maximum welding current of 500A and a 415V three-phase power supply, it delivers stable DC arc performance for high-current welding operations.
Designed for professional use, this machine features digital parameter displays, overvoltage and undervoltage protection, thermal protection, and Voltage Reduction Device (VRD) functionality. Its high-efficiency inverter technology helps provide smooth arc performance with reduced spatter. It is suitable for general-purpose, low-hydrogen, and stainless-steel electrodes, with scratch-start TIG welding available using optional compatible accessories.
