Miller® Dynasty® 280 DX Multiprocess TIGRunner® 907514007
The Miller Dynasty® 280 DX AC/DC Multiprocess TIGRunner® is a 280 amp, multi-process welding package that comes complete with Coolmate™ 1.3 water cooler and Small Runner™ cart. is capable of stick and advanced TIG welding and has CV circuitry for MIG welding. When paired with a Miller voltage sensing wire feeder, the 280 DX multiprocess is the only welder you'll need on the jobsite to perform MIG, Stick, AC/DC TIG welding and air carbon arc gouging.
The Dynasty 280 DX multiprocess has built in TIG pulse and advanced AC wave forms and provides up to 280 amps of welding output. At just 55 pounds, the Dynasty 280 DX multiprocess can weld materials up to 3/8 inch thick, yet weighs hundreds of pounds less than comparable welders in the same welding output class. When using a water-cooled TIG torch, the 280 DX multiprocess utilizes Cooler-On-Demand™ technology to save energy and prolong the life of your Miller Coolmate™ 1.3 cooler and OPTIONAL TIG torch.

FREE Optrel® Panoramaxx CLT Silver auto-darkening welding helmet ($744.00 MSRP Value)
Get a FREE Optrel® Panormaxx CLT Silver auto-darkening welding helmet ($744.00 MSRP Value) with purchase of a Miller® Dynasty® 280 DX multi-process welder. Expires 9/30/22. (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
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.
Out-Of Position Welding is possible with Optrel®'s unique shell design, which has no seams or edges where weld spatter can collect.
