Item Details

  • Miller™ Welder Machine system measuring 8. 6" X 22. 5" X 13. 6" comes with a remote foot control, Dynasty™ 280 DX power source with CPS, 8' primary cord, 2 dinse 50 mm connector, coolmate 1. 3, small runner cart and remote foot control weldcraft W-280 torch kit. 1 or 3 Phase welder uses AC/DC TIG, pulsed TIG and stick process. The Welder has a welding current rating of 1 - 280 A. Welding system delivers output rating of 235 A at 19. 3 V and offers 60% duty cycle during TIG process. Welder also delivers output rating of 180 A at 27. 2 V and 60% duty cycle during stick process. Welding system is designed for precision fabrication, heavy fabrication, aerospace, aluminum ship repair, anodized aluminum fabrication and industrial applications. It has in-built pulser that reduces heat input and adds arc stability. Welding system features sleep timer that conserves electricity. It features Pro-Set™ to eliminate the guesswork when setting weld parameters. It features Auto-Line™ that offers flexibility by automatically connecting to 208 - 575 VAC. Welding system has Blue Lightning™ high-frequency arc starter to offer non-contact arc initiation. It employs Wind Tunnel Technology™ to offer protection for internal electrical components from airborne contaminates. Welding system features Fan-On-Demand™ power source cooling system for low noise and offers thermal overload protection.


  • Upgradeable and Expandable: Front panel memory card data port provides the ability to easily upgrade software and expand product features
  • Auto-Line Power Management Technology: Allows hookup to either single-phase or three-phase electrical input from 208-575 V with no manual linking, providing convenience in any job setting. An ideal solution for dirty or unreliable input power
  • 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
  • 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
  • Portable with adjustable shoulder strap: Weighing in at just 52 pounds, the Dynasty 280 is extremely portable and easy to transport featuring dual carry handles and a carrying strap
  • 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
  • Pro-Set Feature (professional settings): This feature 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
  • Weldcraft™ W-280 (WP-280) TIG Torch: Two-piece torch head and exclusive Super Cool™ Technology provides additional surface area to increase cooling efficiency and capacity
  • Torch body includes an anti-rotation feature and multi-position locking to prevent handle movement during welding and improve operator control
  • Mechanical fittings provide a secure gas and water connection to prevent leakage and allow easy hose replacement
