Descriptions

The Miller Dynasty 400 AC/DC is a high-capacity, professional TIG (GTAW) and Stick (SMAW) welding power source engineered for demanding industrial, fabrication, and repair applications. It combines robust welding output, full AC/DC capability, and advanced digital control features to handle thick aluminium, exotic alloys, and heavy steel work with precision and reliability.

Key Features & Benefits

  • Powerful Output — Delivers up to 400 A with strong arc performance, capable of welding aluminium and steel in demanding settings.

  • Auto-Line™ Wide Input Voltage — Accepts 208–600 V single- or three-phase without manual linking, making it ideal for variable or unpredictable power environments.

  • Advanced AC Arc Control & Waveform Options
    • Multiple AC waveforms (square, soft square, sine, triangular) for precise oxide cleaning, puddle control, and directional control.
    • AC balance and frequency adjustments give control over cleaning action and arc cone focus.

  • QuietPulse™ Technology — Helps reduce audible noise when using DC pulse modes by smoothing transitions between background and peak currents.

  • Smart Interface & Memory — LCD display with guided menus, parameter locking (“Locks & Limits”), and program memory to save and recall multiple weld profiles.

  • Pro-Set™, Blue Lightning™, Lift-Arc™ — Features to simplify setup and enhance arc starts:
      • Pro-Set™ offers preset control guidance for balance, pulse, etc.
      • Blue Lightning™ provides reliable HF arc initiation.
      • Lift-Arc™ allows AC or DC arc start without HF, useful in sensitive environments.

    Stick Welding Capability     — Full support for SMAW including DIG control, Hot Start, and Stick-Stuck™ protection.

  • Cooling & Integration — Includes Cooler Power Supply (CPS) receptacle for Miller’s Coolmate™ 3.5, and “Cooling-On-Demand” operation to save energy and reduce noise.

  • Rugged Design, Connectivity & Updates — USB interface for firmware updates, meter calibration, and backing up parameters.

  • Typical Application Range — Ideal for heavy fabrication, aerospace, ship repair, and welding thicker sections of aluminium and steel.
