The machine is a rugged, portable, and versatile dual-function (TIG and Stick) all-in-one welding machine. The unit can switch between AC or DC TIG welding, making it suitable for use with most ferrous and ferrous materials such as stainless steel, mild steel, brass, titanium, and aluminum. The pulse function of this aluminum welding machine combined with the HF start makes it the ideal choice for welders who want to perform high-quality TIG welding on very thin materials without distortion. The IGBT technology improves welding performance and reliability. You can get precise arc control with high-frequency starting, and the menu design is user-friendly. The welding machine is versatile and can weld stainless steel, mild steel, aluminum, brass, and other materials, including very thin ones. The iTIG250ACDC square wave inverter enables precise welding of fine aluminum materials. With excellent stick welding properties, you can use the most common sticks (6010, 6013, 7018) available on the market. The self-adjustable arc force ensures stable operation while welding over long distances. You can easily set the pre-flow, post-flow, start current, up and down slope time, and end current level, making it a user-friendly welding machine.
