GB TIG 400IJ IGBT MOSFET Welding Machine – Heavy-Duty Industrial TIG & MMA Welding Solution

The GB TIG 400IJ IGBT MOSFET Welding Machine is a high-performance industrial inverter welder designed for DC TIG (GTAW) and MMA (Stick) welding applications. Built with advanced IGBT inverter technology, it delivers excellent arc stability, high energy efficiency, and reliable performance for continuous heavy-duty fabrication and maintenance work. It supports HF (High Frequency) arc starting, making TIG arc ignition smooth and precise while producing high-quality welds with minimal spatter.

Operating on a 3 Phase AC 415V power supply, the TIG 400IJ offers an output current range of 10–400A, making it suitable for welding stainless steel, carbon steel, copper, and other ferrous and non-ferrous metals. With adjustable pulse frequency, upslope/downslope, start and stop current control, and post-gas flow adjustment, it provides excellent flexibility for professional welding applications.
