Miller Dynasty 400 AC/DC TIG Welder

The Miller Dynasty 400 has the latest technology and is powerful with a compact AC/DC inverter which delivers superior arc performance with total AC arc-shaping capabilities. Auto-Line™ allows connection to any voltage or frequency in the world while using half the power of a conventional machine. 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.
• 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 – 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.
• AC/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.
• AC frequency control adds additional stability when stick welding in AC for smoother welds.
• AC TIG Features
• Independent amplitude/amperage control allows EP and EN amperages to be set independently to precisely control heat input to the work and electrode.
• Balance control provides adjustable oxide removal which is essential for creating the highest quality aluminium welds. These models provide extended ranges.
• Frequency controls the width of the arc cone and can improve directional control of the arc.
• DC TIG Features
• Exceptionally smooth and precise arc
• Pulse function can increase puddle agitation, arc stability and travel speeds while reducing heat input and distortion.
