Miller Dynasty 400 TIG Welder 907717

Miller Dynasty® 400 TIG Welder 907717

The Miller Dynasty® 400 is a 400 amp AC/DC TIG welder that features advanced AC waveforms and pulsed TIG welding. The Dynasty 400 operates on either single phase or three phase input power. Miller's Auto-Line™ technology allows connection to any input voltage in the world while using half the power of a non-inverter welding machine.

The Dynasty 400 offers design improvements over previous Dynasty 350 models. New design benefits include: increased resistance to adverse environmental conditions, memory card port for easy software updates or expansion and improved arc stability for AC welding. 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 Dynasty 400 can also be run in manual mode, allowing you to customize your own welding parameters.

Direct replacement for the Miller Dynasty® 350.

Features

Auto-Line™ allows for any input voltage hookup (208 575 V) with no manual linking, providing convenience in any job setting. Ideal solution for dirty or 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-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

AC TIG Features

AC Pulsed TIG standard 0.1 to 500 PPS

AC Balance (50-99%) controls the amount of oxide cleaning (amperage time in EN) which is essential for high quality welds on aluminum.

AC frequency (20-400 hz)controls the width of the arc cone and the force of the arc.

Advanced AC Waveforms



DC TIG Features

DC Pulsed TIG standard 0.1 to 5,000 PPS

Exceptionally smooth and precise arc for welding exotic materials.

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.

AC frequency control adds stability for smoother welds when AC Stick welding.
