Miller Dynasty® 800 TIG Welder 907719
The Miller® Dynasty® 800 is an 800 amp AC/DC TIG welder that features advanced AC waveforms and pulsed TIG welding. The Dynasty 800 operates on either single phase or three phase input power and is capable of welding up to 1 inch thick aluminum. Miller's Auto-Line™ technology allows connection to any input voltage in the world while using half the power of a non-inverter welding machine.
The Dynasty 800 offers design improvements over previous Dynasty 700 welders. New design benefits include: increased resistance to adverse environmental conditions, memory card port for easy software updates or expansion and improved arc stability for AC welding. The Cooler-On-Demand™ feature operates the auxiliary TIG torch cooling system only when needed, saving power and unnecessary wear and tear on the optional water cooler. The Pro-Set™ feature automatically sets welding parameters for you, eliminating guesswork. The Dynasty 800 can also be run in manual mode, allowing you to customize your own welding parameters.

Auto-Line™ allows for any input voltage hookup
(208–575 V) with no manual linking,
providing convenience in any job setting.
Ideal solution for dirty or unreliable power.
Meter calibration allows digital meters to
be calibrated for certification.
Cooler Power Supply (CPS)
is an integrated 120-volt
dedicated-use receptacle for
the Coolmate™ 3.5.
Wind Tunnel Technology™
protects internal electrical
components from airborne
contaminants, extending the
Fan-On-Demand™ power source
cooling system operates only when
needed, reducing noise, energy use
and the amount of contaminants
pulled though the machine.
Lift-Arc™ provides AC or DC
arc initiation without the use of
Blue Lightning™ high-frequency (HF)
arc starter for non-contact arc initiation.
Provides more consistent arc starts
and greater reliability compared to
traditional HF arc starters.
Program memory features nine
independent program memories
that maintain/save your parameters.
Auto-postflow adjusts the length of
postflow time based on the amperage
setting, shielding your tungsten
and eliminating the need to set the
