Cooler Power Supply (CPS)is an integrated 120-voltdedicated-use receptacle for the Coolmate™3.5.Cooler-On-Demand™featureoperates the auxiliary coolingsystem only when needed,reducing noise, energy use,and airborne contaminantspulled through the cooler.Wind Tunnel Technology™protects internal electricalcomponents from airbornecontaminants, extending theproduct life.Fan-On-Demand™powersource cooling systemoperates only when needed,reducing noise, energy use and the amount ofcontaminants pulled thoughthe machine.DC TIG FeaturesExceptionally smooth andprecise arc for weldingexotic materials.Pulse. Pulsing canincrease puddle agitation,arc stability and travelspeeds while reducing heat input and distortion.These models provideextended ranges.DC Stick FeaturesDIG control allows the arc charac teristics to be changed for specificapplications and electrodes.Lower the DIG setting forsmooth running electrodeslike E7018 and increase the DIG setting for stiffer,more penetrating electrodeslike E6010. Hot Start™adaptive controlprovides positive arc startswithout sticking.Maxstar 800Maxstar 400Lift-Arc™provides DC arcinitiation without the use ofhigh frequency.Blue Lightning™high-frequency(HF) arc starter for non-contactarc initiation. Provides moreconsistent arc starts andgreater reliability compared to traditional HF arc starters.Program memory features nine independent programmemories that maintain/save your parameters.Auto-postflow adjusts the length of postflow time based onthe amperage setting, shielding your tungsten and eliminatingthe need to set the postflow time.International HeadquartersMiller Electric Mfg.
