Miller Dynasty 300 AC/DC Tig Welder. This package is supplied ready to weld with Tig power source, cart, Coolmate 3.1 chiller, CK 20 tig torch, earth lead and gas regulator, Miller RFCS 14 HD remote foot control, optional Miller wireless foot control 300429.

The New Miller Dynasty 300 AC/DC Tig welder  is a truly versatile machine that can work from a 230 volt single phase, 32 amp electrical supply as found at farms, workshops and many homes in the UK or from an Industrial 415 v 3 phase 16 amp supply.  

Welding range 1-300 amp  
Tig Duty cycle 250 amps @ 60 duty cycle

Latest technology - this powerful, compact AC/DC inverter delivers superior arc performance with total AC arc shaping capabilities. Auto-Line™ technology allows connection to any voltage or frequency in the world while using half the power of a conventional welding machine.

DC TIG Features Exceptionally smooth and precise arc High-Speed DC TIG Pulse Controls

AC TIG Features  Extended 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.. 4 AC waveforms, soft squarewave, advanced squarewave, sine wave, triangular wave. 

Auto-Line Power Management Technology

Cooler Power Supply (CPS)

Upgradeable and Expandable

Cooler-On-Demand™

Stick Features

Tailored arc control (DIG) allows the arc characteristics 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.

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. 

Programmable start parameters allow independent starting conditions based on process and memory selections (amperage, time and polarity). 

High-frequency arc starter for non-contact arc initiation. Lift-Arc™ start provides AC or DC arc starting without the use of high frequency 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. 

TIGRunner® packages feature a 3.5 gallon (13.2 L) cooling system. The cart is equipped with cylinder carrying capabilities, filler rod holder, foot pedal holder, torch and cable holders. A pullout Drawer provides additional storage for torch consumables and tools.

Package includes Miller Dynasty 300 power source, Miller Tigrunner, Miller coolmate 3.1 water cooler, Undergear/trolley, WP20  tig torch, earth lead, regulator,  flow metre and Miller RFCS 14 foot control unit .
