907719 - Miller Dynasty 800 AC/DC TIG Welder 208-575V

Ultimate Arc Control for Critical Welds

For professional welders who demand total control over their arc, the Miller Dynasty 800 sets the standard. This machine is not just about raw power; it is about refining that power to produce X-ray quality welds on exotic metals and thick aluminum sections. The Dynasty 800 features independent amplitude and amperage control, allowing you to set EP and EN amperages independently. This precise control over heat input to the work and the electrode is essential for managing bead profile and cleaning action on aluminum.

The machine offers a suite of advanced AC waveforms to tailor the arc to your specific application. Advance Squarewave provides a fast-freezing puddle for deep penetration and high travel speeds. Soft Squarewave delivers a buttery smooth arc with excellent puddle control. Sine Wave mimics traditional transformer machines for a familiar feel, while Triangular Wave reduces heat input, perfect for thin gauge aluminum. Additionally, the high-speed DC TIG pulse capability (up to 5000 pulses per second) increases arc stability and reduces heat input, minimizing distortion and warpage.

Equipped with Blue Lightning™ high-frequency arc starter, the Dynasty 800 ensures consistent, non-contact starts every time. The integrated Cooler Power Supply (CPS) simplifies your setup by powering the Coolmate™ 3.5 directly from the machine, ensuring your torch is protected and cooling is active only when the arc is struck. With program memory to save your favorite settings and a front panel data port for software upgrades, the Dynasty 800 is built to adapt to the future of welding technology.
