Miller® Dynasty® 300 TIGRunner® 907818002

The Miller® Dynasty® 300 TIGRunner® is an advanced 300 amp TIG welder package that comes complete with Coolmate™ 1.3 water cooler and Small Runner® cart. Adjustable TIG pulse can be set from 0.1 to 500 pulses per second (pps). AC TIG frequency adjustment has a range from 20-400 Hz. Extremely low amperage TIG output allows you to go down to as low as 2 amps on AC and 1 amp on DC. Wave forms are adjustable in both AC and DC pulsed TIG welding modes for a truly customized welding arc.

The Dynasty 300 welds material up to 3/8" thick. It can go just about anywhere and run on just about any input power, single-phase or three-phase. Auto-Line™ senses input voltage and phase and instantly adjusts the welder to the optimal operational settings without manual linking. The simplified user interface with large 4.5 inch LCD display helps ensure proper weld parameters for your job. The Pro-Set™ mode eliminates the guesswork from set up by automatically choosing the most common weld settings for your application.

When using a water-cooled TIG torch, the 300 utilizes Cooler-On-Demand™ technology to save energy and prolong the life of your optional TIG torch and Miller Coolmate™ 1.3 cooler. It also comes standard with CPS (Coolant Power Supply), an integrated 120V dedicated outlet for running your Coolmate water circulator.

IP23 rating This equipment is designed for outdoor use. It may be stored, but is not intended to be used outside during precipitation unless sheltered.

    This equipment is designed for outdoor use. It may be stored, but is not intended to be used outside during precipitation unless sheltered.

    AC TIG Features
  • AC Pulsed TIG (0.1 to 500 pps)
    Controls the amount of heat going into the weld to minimize warping or distortion, especially on thin material.
  • AC Balance (30-99%)
    Controls the amount of oxide cleaning (amperage time in EN) which is essential for high quality welds on aluminum.
  • AC frequency (20-400 hz)
    Controls the width of the arc cone and the force of the arc.
  • Advanced AC Waveforms

    DC TIG Features
  • DC Pulsed TIG (0.1 to 500 pps)
    Controls the amount of heat going into the weld to minimize warping or distortion, especially on thin material
  • Exceptionally smooth and precise arc
    For welding exotic materials.
  • Pulse Waveforms
    Square provides a fast freezing puddle for ultimate arc control.
    Sine produces a reduced audible sound and provides a more fluid puddle that is good for overlaying applications.
    Triangular provides a quick-forming puddle while further reducing heat for thin materials.

    Stick Features (AC/DC)
  • Tailored arc control (DIG)

  • FREE Optrel® Panoramaxx CLT Silver auto-darkening welding helmet

    Get a FREE Optrel® Panormaxx CLT Silver auto-darkening welding helmet with the purchase of this Miller® Dynasty® 300 TIG welder. While supplies last. (No substitutions allowed.)

    The Optrel® Panoramaxx CLT Silver auto-darkening welding hood features Crystal shade 2.0 light state that is unmatched in the world for color and clarity and provides up to 6X the viewing area of a standard 2" X 4" auto-dark welding lens. The key to this revolutionary technology is the size and shape of the ADF, coupled with the unique Panoramaxx shell design, which allows the welding lens to be positioned closer to your face. The Panoramaxx also has advanced features like SHADETRONIC®, which automatically adjusts the shade level based on the brightness of the arc and True Color, which allows for realistic color perception in light or dark states.

    All Panoramaxx welding helmets now come with the revolutionary IsoFit® headgear. It is the only welding headgear in the world that wraps the entire crown of the head with multiple touch points to provide a custom fit like never before. Independent "three dimensional" size, width and height adjustments ensure all day comfort with a secure hold.

    The Panoramaxx CLT has a built-in rechargeable battery that does not need replacing. The battery is charged through arc light or when manual charging is necessary, a micro USB charging port. It comes complete with micro USB cable, helmet bag and Oprel's 2+1 warranty.

  • PANORAMIC FIELD OF VISION - The Panoramaxx CLT offers a 6 times larger field of vision than standard welding helmets and is still a lightweight at only 21.5 ounces.
  • CRYSTAL LENS TECHNOLOGY 2.0 - Shade 2.0 light state provides the brightest view of your working environment available anywhere. The natural color and clear optics supplied by CLT increases both safety and efficiency in the workplace.
  • SHADETRONIC® - Detection of the arc brightness and fully automated shade level adjustment from 4 to 12. Adjusts automatically to the changing light conditions of the current welding method. A sophisticated SHADETRONIC® sensor continuously measures the light intensity of the welding arc and regulates the glare protection progressively and fully automatically.
  • FADETRONIC - Patented Optrel FadeTronic technology gradually lightens the auto darkening filter after the welding arc is extinguished. The unpleasant afterglow is faded out especially for high amperage applications. Eye fatigue is significantly reduced, enhancing worker safety. FADETRONIC can be adjusted for a custom user experience.
  • TRUE COLOR - A specially developed UV/IR filter allows the realistic color perception typical of Optrel®, bringing color to the welder's world. TRUE COLOR passes more colors of the spectrum through compared to standard "green" spectrum welding lenses.

  • Optrel Re-Charge - With its rechargeable power-pack, changing batteries is no longer necessary. Thanks to the latest solar technology, a rechargeable lithium-polymer battery is recharged either by the welding light or by the ambient light. In addition, the battery can also be charged directly with any USB charger via a micro-USB interface.
  • 5-Point Detection - intelligent sensor control with five sensors. Sophisticated software and clever positioning of four sensors at the corners and one sensor in the upper center ensures the lens is switched on and off perfectly, even in the most difficult lighting conditions or in awkward positions.
  • IsoFit® headgear sets a new standard of wearing comfort. It is the only product worldwide that can be adjusted in width, length and height i.e. three-dimensionally to any head shape, so that the helmet really fits "like a glove."

  • FadeTronic® - gradually lightens lens when switching from dark (welding) to light state to ease eye fatigue.
  • Sensitivity Adjustment - allows operator to change lens switching sensitivity for varying ambient light conditions or outdoor welding in sunlight.
  • Grinding Mode - external grind control allows user to switch between welding mode and shade 2 grinding mode quickly and easily.
  • Delay Function
  • Out-Of Position Welding is possible with Optrel®'s unique shell design, which has no seams or edges where weld spatter can collect.
