AC Waveforms
Advance Squarewave provides a fast freezing puddle, deep penetration, and fast travel speeds.

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.
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.
Upgradeable and Expandable
Front panel memory card data port provides the ability to easily upgrade software and expand product features. Visit for the latest software upgrades and expansions.
Feature operates the auxiliary cooling system only when needed, reducing noise, energy use, and airborne contaminants pulled through the cooler.
