The Weldnex Cold TIG Welding Machine 300 Amps is a powerful and advanced welding solution engineered for high-precision applications across a wide range of industries. This professional-grade machine offers 4-in-1 functionality, combining DC TIG, DC TIG Pulse, Cold TIG, and MMA/ARC Welding in one compact, inverter-based unit. With a strong focus on quality, control, and efficiency, it is designed to deliver exceptional results in both industrial and workshop environments.

The Cold TIG function is a standout feature, specifically developed for welding ultra-thin sheets, stainless steel, and heat-sensitive metals. It operates with minimal heat input, reducing the risk of burn-through, distortion, or discoloration, making it perfect for delicate welding tasks in electronics, decorative metalwork, HVAC, and precision fabrication. The TIG Pulse mode allows better control of arc energy and penetration, especially beneficial for varying thicknesses or high-quality bead appearance.

With a high output of 300 Amps, this welding machine provides stable arcs, deep penetration, and smooth finishes on a wide variety of ferrous and non-ferrous materials. The MMA/ARC welding mode adds versatility, enabling users to weld with conventional electrodes, even in outdoor or high-current-demand applications. Built using IGBT inverter technology, the machine ensures energy efficiency, lightweight portability, and consistent performance even in fluctuating power conditions.

Its digital control panel makes it easy to adjust parameters such as current, pulse frequency, and arc force, giving welders precise control over every aspect of the welding process. Safety features like overheat protection, voltage fluctuation compensation, and anti-stick function ensure reliable and safe operation throughout extended use.
