907686 - Miller Dynasty 210 DX AC/DC TIG/Stick Welder

Miller Dynasty 210 DX Technical Overview

The Miller Dynasty 210 DX (Stock No. 907686) is a compact, inverter-based AC/DC TIG and Stick power source designed for high-precision industrial applications. Engineered with Miller's proprietary Auto-Line™ Power Management Technology, this unit automatically adapts to any primary input voltage ranging from 120 V to 480 V, single-phase or three-phase, 50 or 60 Hz. This eliminates the need for manual linking mechanisms, ensuring safe and reliable operation across diverse electrical environments. The unit delivers a rated output of 210 Amps at 18.4 Volts with a 60% duty cycle, making it capable of welding materials up to 1/4 inch (6.4 mm) thick.

The "DX" designation indicates a full-featured interface providing extensive control over AC welding parameters. Operators can adjust AC frequency (20-400 Hz) to control arc cone width and direction, and AC balance (30-99% EN) to fine-tune oxide cleaning versus penetration. Additionally, the machine offers four selectable AC waveforms: Advanced Squarewave for fast freezing and deep penetration, Soft Squarewave for a buttery arc with maximum puddle control, Sine Wave for traditional soft arc characteristics, and Triangular Wave for reduced heat input on thin gauge aluminum. The integrated Blue Lightning™ high-frequency arc starter ensures consistent non-contact starts, programmable from 0.002 to 0.030 inches.

For Stick (SMAW) welding, the Dynasty 210 DX includes DIG control to adjust arc characteristics for specific electrodes (e.g., E6010 vs. E7018) and Hot Start™ adaptive control to prevent electrode sticking during ignition. The machine is housed in a robust case featuring Wind Tunnel Technology™, which routes internal airflow to cool power components while protecting sensitive electronics from dust and debris. A front-panel memory card data port facilitates software upgrades and feature expansions, ensuring the equipment remains current with the latest welding technologies.
