951000007 - Miller Maxstar 400 DC TIG Complete Water-Cooled Package

Ultimate Precision for Professional Welders

Take your TIG welding to the next level with the Miller Maxstar 400 Complete Package. This isn't just a welder; it's a fully integrated welding station designed for the professional who demands perfection in every bead. Whether you are working on aerospace components, food and beverage piping, or custom fabrication, the Maxstar 400 provides the smooth, stable DC arc that Miller is famous for. This package arrives ready to work, complete with a water-cooled torch system that keeps your hands cool and your consumables lasting longer during marathon welding sessions.

User-Friendly Interface with Pro-Set

While the Maxstar 400 is a heavy-industrial machine, it is incredibly approachable thanks to Miller's Pro-Set feature. Pro-Set eliminates the guesswork when setting weld parameters by providing pre-set controls for speed, balance, and background amps that are optimized by Miller's engineers. If you need to fine-tune, the interface allows for deep customization, but Pro-Set gets you into the welding zone faster. Additionally, the machine features 9 independent program memories, allowing you to save your favorite settings for repeat jobs, saving setup time and ensuring consistency across shifts.

Superior Stick Welding Performance

Don't let the "TIG" label fool you; the Maxstar 400 is a beast of a Stick welder as well. It is designed to run all types of electrodes, including difficult-to-run E6010 cellulosic rods used in pipe welding and E7018 low-hydrogen rods for structural work. The Tailored Arc Control (DIG) feature allows you to change the arc characteristics for specific electrode types, ensuring you don't stick the rod or undercut the plate. The Hot Start adaptive control provides positive arc starts without sticking, making your life easier on every strike.

Ready to Roll

The Complete Package is built around mobility and convenience. The Runner Cart features heavy-duty casters and a low center of gravity, making it easy to move the entire 400-amp station around your shop. The single-cylinder rack holds your argon bottle securely, and the included foot control gives you precise amperage adjustment while you weld. With the Coolmate 3.5 integrated into the cart setup, you have a self-contained, high-performance welding cell that is ready to tackle the thickest plate or the thinnest sheet with equal finesse.
