Miller Electric Maxstar 280 DX 208-575 V, TIGRunner - 907539001

The Maxstar 280 Series is a powerful combination of capability and portability. It can weld up to 3/8 in. thick material. The DC TIG/Stick power sources feature an energy-efficient inverter design and Auto-Line™ technology.

Features

• Auto-Line™ Technology: Allows hookup to either single-phase or three-phase primary input voltage, 208-600 volts dependent on the machine, with no manual linking, providing convenience in any job setting. An ideal solution for dirty or unreliable input power.
• Pro-Set™ Feature: 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.
• Stick Features: Tailored arc control (DIG) allows the arc characteristics 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.
• Portable with adjustable shoulder strap: Weighing in at just 47 pounds, the Maxstar 280 is extremely portable and easy to transport featuring dual carry handles and a carrying strap.
• Base and Deluxe Models Available: Base model provides essential TIG and Stick functions and provides operator-friendly, menu-driven features. The DX model adds extended ranges to sequencer and full trigger options, preflow and pulser functions.
• QuietPulse™: QuietPulse is activated by changing the waveshape for DC pulse welding, creating a slower, more fluid transition between the background and peak amperage to create the least possible audible noise.
• Cooler Power Supply (CPS): An integrated 120-volt dedicated-use receptacle to power the Coolmate™ 1.3. The power switch on the machine activates the receptacle to help prevent torch failure. Available on select models.
• Upgradeable and Expandable: Front panel memory card data port provides the ability to easily upgrade software and expand product features. Visit MillerWelds.com/tigsoftware for the latest software upgrades and expansions.
• 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 featureand multi-position locking to prevent handlemovement during welding and improve operator control Mechanical fittings provide a secure gas andwater connection to prevent leakage and alloweasy hose replacement
