AC/DC GTAW welding machine
AC/DC GTAW (TIG) Welding Machine
Overview
The AC/DC GTAW (Tungsten Inert Gas) Welding Machine is designed to demonstrate and perform high-precision welding on both ferrous and non-ferrous metals. This trainer provides a complete understanding of TIG welding using both AC and DC power modes — essential for welding materials like aluminum, stainless steel, and mild steel.
The system is ideal for training institutions, R&D centers, and fabrication workshops, where clean, strong, and visually appealing welds are required.
