Miller Maxstar® 400 TIGRunner® 907873001
The Miller® Maxstar® 400 TIGRunner® is a highly sophisticated industrial 400 amp DC TIG welder that comes complete with a Coolmate™ 3.5 water cooler and cart. The Maxstar 400 features advanced pulsed DC TIG waveforms and operates on either single phase or three phase, 208 to 600 volt input power. Miller’s Auto-Line™ technology allows automatic connection to any input voltage in the world, without manually linking.
The Maxstar 400 offers a 7-inch LCD display with simplified user interface. QuitePulse™ significantly reduces pulse “chatter” when using sine or triangular waveforms in DC pulsed-TIG welding modes. The Cooler-On-Demand™ feature operates the auxiliary TIG torch cooling system only when needed, saving power and unnecessary wear and tear on the optional water cooler. The Pro-Set™ feature automatically sets welding parameters for you, eliminating guesswork. The Maxstar 400 can also be run in manual mode, allowing you to customize your own welding parameters.

Features
- Auto-Line™
Allows for any input voltage hookup (208 600 V) with no manual linking, providing convenience in any job setting. Ideal solution for dirty or unreliable power. - Cooler Power Supply (CPS)
Is an integrated 120-volt dedicated-use receptacle for the Coolmate 3.5. - Wind Tunnel Technology™
Protects internal electrical components from airborne contaminants, extending the product life. - Fan-On-Demand™
Power source cooling system operates only when needed, reducing noise, energy use and the amount of contaminants pulled though the machine. - Lift-Arc™
Provides AC or DC arc initiation without the use of high frequency. - 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. - Program memory
Allows easy naming, saving and recalling of favorite weld settings.
Deliver more productivity by eliminating the need to manually set the parameters.
Deliver consistent quality by welders of all skills. - Auto-postflow
Adjusts the length of postflow time based on the amperage setting, shielding your tungsten and eliminating the need to set the postflow time. - Wireless remote compatible
Fully compatible with Miller wireless remote control solutions so you can work the way you want
