What's Included

Maxstar® 400
8 ft. (2.4 m) primary cord
(2) 50 mm Dinse style connectors

DC TIG Features

Exceptionally smooth and precise arc for welding exotic materials. High-speed DC TIG pulse controls - Pulse frequency capable of pulsing 5000 pulses per second. Pulsing adds arc stability, reduces heat input and warpage and can increase travel speeds. Other parameters include peak amperage, peak time and background amperage.

Stick Features (DC)

Tailored arc control (DIG) allows the arc characteristics 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.

Blue Lightning™ - High Frequency Arc Starter

For more consistent non-contact starts and greater reliability compared to traditional HF arc starters.

Program memory

Program memory features 9 independent program memories that maintain/save your parameters.

Cooler Power Supply (CPS)

An integrated 120-volt dedicated-use receptacle to power the Coolmate™ 3.5. The power switch on the Dynasty also activates the receptacle to help prevent torch failure.

Meter Calibration

Allows meters to be calibrated for certification.

Auto-Line Power Management Technology

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.

Upgradeable and Expandable

Front panel memory card data port provides the ability to easily upgrade software and expand product features. Visit MillerWelds.com/tigsoftware for the latest software upgrades and expansions.

Cooler-On-Demand™

Feature operates the auxiliary cooling system only when needed, reducing noise, energy use, and airborne contaminants pulled through the cooler.
