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. You can pair with a feeder and it is the only welder you will ever need to perform MIG/Stick, AC/DC TIG 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.
AC/DC TIG (GTAW)
Pulsed TIG (GTAW-P)
Air carbon arc (CAC-A)
MIG (GMAW) - when paired with voltage sensing feeder.
Built-in CV circuitryfor MIG welding when paired with a Miller voltage sensing feeder.
The DX modeloffers full AC features, including advanced waveforms and wide ranges of balance and frequency.
Upgradeable and expandable.Front panel memory card data port provides the ability to easily upgrade software and expand product features.
Pro-Set™ feature (professional settings)eliminates the guesswork when setting weld parameters. Use Pro-Set when you want the speed, convenience and confidence of pre-set controls. Simply select the feature and adjust until Pro-Set appears on the display. The Pro-Set feature is available for Balance, Frequency, Pulse, and DIG parameters.
Sleep timerconserves electricity. This programmable feature will power down the machine if it sits idle for a specific time.
Auto-Line™provides state-of-the-art flexibility by automatically connecting to 208-575 VAC, single- or three- phase power without removing the covers to relink the power source. No longer is there a concern if you have the correct machine for the shop or the job site.
Cooler Power Supply (CPS).An integrated 120-volt dedicated-use receptacle to power the Coolmate™ 1.3. The power switch on the Dynasty also activates the receptacle to help prevent torch failure.
Lift-Arc™starting provides x-ray clean welds in AC or DC arc starting without the use of high frequency.
Blue Lightning™high-frequency arc starter for non-contact arc initiation. Provides more consistent arc starts and greater reliability compared to traditional HF arc starters. Easy to set and increases productivity
Meter calibration.Digital meters can be calibrated to a standard device for certification.
Wind Tunnel Technology™protects internal electrical components from airborne contaminates, extending the product life.
Fan-On-Demand™power source cooling system operates only when needed, reducing noise, energy use and the amount of contaminates pulled though the machine.
Cooler-On-Demand™feature operates the auxiliary cooling system only when needed, reducing noise, energy use, and airborne contaminants pulled through the cooler.
Thermal Overload Protection -Internal components are protected from damage by thermal overload protection which automatically shuts down the unit if duty cycle is exceeded or air flow and cooling are restricted.
Wireless remote compatible -fully compatible with Miller wireless remote control solutions — so you can work the way you want
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.
AC TIG Features
AC Pulsed TIG standard0.1 to 500 PPS
AC Balance (50-99%)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 standard 0.1 to 500 PPS
Exceptionally smooth and precise arc for welding exotic materials.
CV outputof the power source gives this unit MIG process capabilities when paired with a SuitCase® X-TREME™ 8VS (or other voltage sensing feeder). The feeder is powered off the arc voltage of the power source and can run both solid and flux-cored wires
Stick Features (AC/DC)
Tailored arc control (DIG)allows the arc characteristic to be changed for specific applications and electrodes. Smooth running 7018 or stiffer, more penetrating 6010.
Hot Start™adaptive control provides positive arc starts without sticking.
AC frequency controladds stability for smoother welds when AC Stick welding.
Stick-Stuckdetects if the electrode is stuck to the part and turns the welding output off to safely and easily remove the electrode. Menu selectable.
