Industrial Applications Quick Specs Precision Fabrication Heavy Fabrication Pipe and Tube Fabrication Aerospace Aluminum Ship Repair Anodized Aluminum Fabrication AC/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) 2 – 280 A (AC) Rated Output 200 A at 28 V, 60% Duty Cycle Weight 52 lb. (23.6 kg) Upgradeable and expandable. Front panel memory card data port provides the ability to easily upgrade software and expand product features. AC TIG Features Extended AC balance (50–99%) controls the amount of oxide cleaning (amperage time in EN) which is essential for high quality welds on aluminum. AC frequency (20–400 Hz) controls the width of the arc cone and the force of the arc. Visit MillerWelds.com/TIGSoftware for the latest software upgrades and expansions. Pro-Set™ feature (professional settings) eliminates the guesswork when setting weld parameters. Use Pro-Set when you want the speed, convenience and confidence of pre-set controls. Simply select the feature and adjust until Pro-Set appears on the display. The Pro-Set feature is available for Balance, Frequency, Pulse, and DIG parameters. Sleep timer conserves electricity. This programmable feature will power down the machine if it sits idle for a specific time. Miller recommends aluminum filler. Meter calibration. Digital meters can be calibrated to a standard device for certification. Allows 208 – 575 V input voltage hookups. Cooler Power Supply (CPS). An integrated 120-volt dedicated-use receptacle to power the Coolmate™ 1.3. The power switch on the Dynasty also activates the receptacle to help prevent torch failure. Available on select models, see page 6. Advance Squarewave, fast freezing puddle, deep penetration and fast travel speeds. Soft Squarewave for a soft buttery arc with maximum puddle control and good wetting action. Sine wave for customers that like a traditional arc. Quiet with good wetting. Triangular wave reduces the heat input and is good on thin aluminum. Fast travel speeds. Wind Tunnel Technology™ protects internal electrical components from airborne contaminates, extending the product life. Fan-On-Demand™ power source cooling system operates only when needed, reducing noise, energy use and the amount of contaminates pulled though the machine. Blue Lightning™ high-frequency arc starter for non-contact arc initiation. Provides more consistent arc starts and greater reliability compared to traditional HF arc starters. Easy to set and increases productivity. Exceptionally smooth and precise arc for welding exotic materials. Stick Features (AC/DC) Tailored arc control (DIG) allows the arc characteristic 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. AC frequency control adds stability for smoother welds when AC Stick welding. 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. Power source is warranted for 3 years, parts and labor. Original main power rectifier parts are warranted for 5 years. Equipment Sales US and Canada An ITW Company 1635 West Spencer Street P.O.
