The TIG 400 AC/DC machine is an advanced welding device designed for both AC (Alternating Current) and DC (Direct Current) welding processes. It is particularly suitable for precision welding tasks, including aluminum (AC mode) and stainless steel or carbon steel (DC mode). The machine provides excellent control over welding parameters, allowing for high-quality welds with minimal spatter. Features often include adjustable pulse settings, a user-friendly interface, and robust build quality, making it ideal for professional welders who require versatility and reliability in their work.
