Miller® Dynasty® 300 Multiprocess TIGRunner® 907819001
The Miller® Dynasty® 300 Multiprocess TIGRunner® is an advanced 300 amp welder package that comes complete with Coolmate™ 1.3 water cooler and Small Runner® cart. When paired with a Miller voltage sensing wire feeder, the 300 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 300 Multiprocess has built in TIG pulse and advanced AC/DC wave forms and provides up to 300 amps of welding output. 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 Multiprocess can weld materials up to 3/8 inch 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 Multiprocess 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.

FREE Optrel® Panoramaxx CLT Black/e3000x PAPR
Get a FREE Optrel® Panormaxx CLT Black/e3000x Powered Air Purifying Respirator with the purchase of this Miller® Dynasty® 300 welder. Expires 3/31/23. (No substitutions allowed.)
Optrel® e3000x PAPR With Panoramaxx CLT Black Welding Helmet 4550-580
The Optrel® e3000x PAPR (Powered Air Purifying Respirator) with Panoramaxx CLT Black welding helmet filters 99.8% of welding particulates, smoke, aerosols and dust to create a cleaner, healthier work environment under the hood. The e3000x HEPA filter carries a TH3 rating, which means you are getting the highest class of protection available in a PAPR system. The blower unit itself weighs less than 3.5 pounds and comes complete with lithium ion battery that provides up to 18 hours of operation between charges.
Certified to the highest level of respiratory protection in its class, TH3 (HEPA), the e3000X filters and removes 99.8% of harmful solid and liquid airborne particles to deliver clean, filtered breathing air. With the e3000X PAPR system, you complement your optrel PAPR welding helmet with a respiratory protection system, which makes no compromises in matters of safety, health and comfort.
Compared to the best in class filter mask (class FFP3), this increases the safety of the user by a factor of ten or even by a factor of 40 when using FFP2 masks.
Complete system comes with e3000x blower motor with hose, TH3 HEPA filter, pre-filter, spark arrestor, battery with charger, belt, Panoramaxx welding helmet with face seal and carry case.
The highest class of protection (TH3/HEPA) from respirable particles (smoke, aerosol, and dust), including Hexavalent Chromium, most commonly present during welding operations.
Up to 18 hours of operation with included lithium ion battery.
Breathing air becomes cleaner by a factor of up to 500.
Even air distribution in the fresh air helmet.
Automatic air flow control.
Additional cooling effect for keeping a cool head about you.
The Optrel® Panoramaxx CLT Black 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.
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 21.2 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.
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.
