TIG 400
The TIG 400 is a robust, industrial-grade TIG/MMA welding machine designed for high-duty operations in structural fabrication, pipeline welding, and pressure vessel applications. Equipped with advanced IGBT inverter technology, this machine delivers seamless arc starts using high-frequency ignition and provides complete control through adjustable arc force, up/down slope, and post-flow functions. Built for demanding environments, the TIG 400 combines performance with safety, passing the 3750V AC dielectric test and featuring intuitive controls for professional results.
Available in Pack: Single-unit pack with inverter power source, water-cooled TIG torch, and earth clamp with cable and Europlug.
