GB TIG 250P AC/DC Welding Machine – Advanced Pulse TIG Welding for Aluminium & Stainless Steel
The GB TIG 250P AC/DC Welding Machine is a high-performance 250A IGBT inverter welder designed for AC/DC Pulse TIG (GTAW) and MMA (Stick) welding applications. Built with advanced IGBT inverter technology, it delivers exceptional arc stability, precise pulse control, and efficient power consumption for professional fabrication and industrial use.
The AC welding mode is ideal for aluminium and magnesium alloys, while the DC mode provides excellent results on stainless steel, mild steel, copper, titanium, and other ferrous and non-ferrous metals. With adjustable pulse frequency, AC balance, upslope/downslope, and high-frequency arc starting, the TIG 250P AC/DC offers superior control for thin-sheet fabrication, precision welding, and high-quality finish work.
