907719001 - Miller Dynasty 800 TIGRunner AC/DC TIG Welder Package

Unmatched Industrial Power and Precision

The Miller Dynasty 800 TIGRunner represents the pinnacle of industrial TIG welding technology, designed for fabricators who demand uncompromising power and precision. Capable of delivering up to 800 amps of welding output, this machine is engineered to handle the thickest materials, including aluminum up to 1 inch thick, with ease. The TIGRunner package integrates the power source with the high-capacity Coolmate™ 3.5 cooling system and a rugged runner cart, creating a mobile, self-contained welding station perfect for heavy manufacturing, aerospace, and shipbuilding environments.

Advanced Waveform and Arc Control

Miller’s advanced AC TIG features give operators total control over the arc. Independent amplitude and amperage control allow for the precise setting of EP and EN amperages, optimizing heat input to both the workpiece and the electrode. The extended AC balance (30–99%) is critical for oxide cleaning on aluminum, ensuring high-quality, defect-free welds. Furthermore, the machine offers four distinct AC waveforms—Advance Squarewave, Soft Squarewave, Sine wave, and Triangular wave—allowing welders to tailor the arc characteristics to the specific joint configuration and material type.

Reliability and Efficiency

Equipped with Auto-Line™ Power Management Technology, the Dynasty 800 connects to any input voltage from 208 to 575 V, single- or three-phase, without manual linking. This flexibility ensures consistent performance even on dirty or unreliable power grids. The Cooler-On-Demand™ feature operates the auxiliary cooling system only when necessary, significantly reducing airborne contaminants, noise, and energy consumption. With the Blue Lightning™ high-frequency arc starter, you get consistent, non-contact starts every time, eliminating tungsten contamination and ensuring weld integrity from the very first pass.

Built for the Future

The front panel memory card data port allows for easy software upgrades, ensuring your machine stays up-to-date with the latest Miller features. With program memory for nine independent settings, operators can quickly switch between jobs without reprogramming, boosting productivity and consistency across shifts.
