Industrial Applications Quick Specs Precision Fabrication Petro Chemical Aerospace Food/Beverage Industry Dairy Shipboard DC TIG (GTAW) Pulsed TIG (GTAW-P) Stick (SMAW) Air Carbon Arc (CAC-A) TIG/Stick Welding Power Source Input Power 208 – 575 V, 3- or 1-Phase Power Amperage Range 1 – 280 A (DC) Rated Output 200 A at 28 V, 60% Duty Cycle Net Weight 47 lb. (21.3 kg) Upgradeable and expandable. Front panel memory card data port provides the ability to easily upgrade software and expand product features. DC TIG Features Pulse. Pulsing can increase puddle agitation, arc stability and travel speeds while reducing heat input and distortion. DX models provide extended ranges. Visit MillerWelds.com/TIGSoftware for the latest software upgrades and expansions. Exceptionally smooth and precise arc for welding exotic materials. Pro-Set™ eliminates the guesswork when setting weld parameters. Use Pro-Set when you want the speed, convenience and confidence of preset controls. Simply select the feature and adjust until Pro-Set appears on the display. DC Stick Features Dual schedule allows operators to switch welding parameters for specific electrodes without readjusting the machine, minimizing downtime and enhancing quality. Base model only (not DX). Sleep timer conserves electricity. This programmable feature will power down the machine if it sits idle for a specific time. Maxstar 280 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™ 1.3. The power switch on the Maxstar also activates the receptacle to help prevent torch failure. Available on select models, see page 6. Wind Tunnel Technology™ protects internal electrical components from airborne contaminates, extending the product life. DIG control allows the arc characteristics to be changed for specific applications and electrodes. Lower the DIG setting for smooth running electrodes like E7018 and increase the DIG setting for stiffer, more penetrating electrodes like E6010. Fan-On-Demand™ power source cooling system operates only when needed, reducing noise, energy use and the amount of contaminants pulled though the machine. Hot Start™ adaptive control provides positive arc starts without sticking. Meter calibration allows digital meters to be calibrated for certification. 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. 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. Power source is warranted for 3 years, parts and labor. Equipment Sales US and Canada An ITW Company 1635 West Spencer Street P.O.
