Miller Maxstar 400 DC Only TIG Welder

The Maxstar 400 provides outstanding arc performance and product reliability. Includes earth leads, gas hose, and 3-year Miller True Blue Warranty.

Key Features:

• 400A
• Auto-Line™ power management technology – Allows for any input voltage hook-up (380–575 V) with no manual linking, providing convenience in any job setting. Ideal solution for unreliable power.
• Meter calibration – Allows digital meters to be calibrated for certification.
• Cooler Power Supply (CPS) – Is an integrated 120-volt dedicated-use receptacle for the Coolmate™ 3.5.
• Cooler-On-Demand™ – Feature operates the auxiliary cooling system only when needed, reducing noise, energy use, and airborne contaminants pulled through the cooler.
• 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.
• Program memory – Features nine independent program memories that maintain/save your parameters.
• Auto-post flow – Adjusts the length of post flow time based on the amperage setting, shielding your tungsten and eliminating the need to set the post flow time.
• Lift-Arc™ – Provides 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.
• DC TIG Features
• Exceptionally smooth and precise arc for welding exotic materials.
• Pulse feature can increase puddle agitation, arc stability and travel speeds while reducing heat input and distortion. These models provide extended ranges.
• DC Stick Features
• 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.
• Hot Start™ adaptive control provides positive arc starts without sticking.
