Miller Dynasty® 280 TIG Welder 907550
Miller Dynasty® 280 TIG Welder provides up to 280 amps of TIG arc and Stick arc welding output. At just 52 pounds, the Dynasty 280 can weld materials up to 3/8 inch thick, yet weight hundreds of pounds less than comparable welders in the same welding output class. The Dynasty® 280 TIG welder provides the basic features that are required for most AC/DC TIG or STICK welding applications using a simple, menu-driven interface.
AC/DC TIG (GTAW)
Pipe and Tube Fabrication

upgrade software and expand
Pro-Set™ feature (professional
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.
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.
Lift-Arc™ starting provides x-ray clean
welds in AC or DC arc starting without
the use of high frequency.
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
Digital meters can be calibrated to a
standard device for certification.
Wind Tunnel Technology™ protects internal electrical
components from airborne contaminates, extending the
Fan-On-Demand™ power source cooling system operates
only when needed, reducing noise, energy use and the
amount of contaminates pulled though the machine
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
AC TIG Features
AC Balance (60-80%) controls the amount of oxide cleaning (amperage time in EN) which is essential for high quality welds on aluminum.
AC frequency (70-150 hz)controls the width of the arc cone and the force of the arc.
DC TIG Features
DC Pulsed TIG standard
0.1 to 250 PPS
Exceptionally smooth and precise arc for welding exotic materials.
Stick Features (AC/DC)
Tailored arc control (DIG)
arc characteristic to be changed for
specific applications and electrodes.
Smooth running 7018 or stiffer, more
Hot Start™ adaptive control provides
positive arc starts without sticking.
AC frequency control
adds stability for
smoother welds when AC Stick welding.
Stick-Stuck detects if the electrode is
stuck to the part and turns the welding
output off to safely and easily remove
the electrode. Menu selectable.

Even though it doesn't have the CPS can you still connect a coolmate later on to this welded?
Yes, you can use a Coolmate 1.3 with the Dynasty 280.

Can this machine use an air cooled torch?
You can install an air cooled tig torch on a Miller Dynasty 280 TIG Welder 907550. However the Dynasty 280 will produce 280 amps output. The WP 26 tig torch which is the which is the heavy duty air cooled tig torch is only rated at 200 amps. If you run this torch at 280 amps it will over heat and eventually fail. If you run this torch at 200 amps or below it will work fine
