907101021  Miller Dynasty 700 AC/DC Tig Welder, 380-575 VAC 3 phase

The ultimate precision AC/DC welding machine with total AC arc shaping capabilities for the ultimate in control. Auto line power management technology 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. Blue Lightning™ high-frequency arc starter for more consistent non-contact starts and greater reliability compared to traditional HF arc starters. Program memory features nine independent program memories that maintain/save your parameters. Auto-postflow calculates the length of postflow time based on the amperage setting. This eliminates the need to independently set the postflow time for different amperages. This feature preserves your tungsten and prevents porosity.

Machine Features

Fan-On-Demand™ (Click for Demonstration) - power source cooling system operates only when needed, reducing noise, energy use and the amount of contaminants pulled through the machine.

Auto-Line™ (Click for Demonstration) - Allows for any input voltage hookup (380–575 V) with no manual linking, providing convenience in any job setting. Ideal solution for dirty or unreliable power.

120-volt auxiliary power receptacle for cooling system or small tools

AC TIG Features

Squarewave AC Waveforms (Click for Demonstration)

Independent amplitude/amperage control allows EP and EN amperages to be set independently to precisely control heat input to the work and electrode.

Extended AC balance (30–99%) controls the amount of oxide cleaning (amperage time in EP) 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.

DC Tig Features

Exceptionally smooth and precise arc for welding exotic materials.

High-speed DC TIG pulse controls. Pulse frequency capable of pulsing 5000 pulses per second. Pulsing adds arc stability, reduces heat input and warpage and can increase travel speeds. Other parameters include peak amperage, peak time and background amperage.

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 additional stability when Stick welding in AC for smoother welds.
