Miller Dynasty 300 TIGRunner 907818002
The Miller Dynasty 300 TIGRunner is an advanced 300 amp TIG welder package that comes complete with Coolmate™ 1.3 water cooler and Small Runner® cart. Adjustable TIG pulse can be set from 0.1 to 500 pulses per second (pps). AC TIG frequency adjustment has a range from 20-400 Hz. Extremely low amperage TIG output allows you to go down to as low as 2 amps on AC and 1 amp on DC. Wave forms are adjustable in both AC and DC pulsed TIG welding modes for a truly customized welding arc.
The Miller Dynasty 300 welds material up to 3/8″ thick. It can go just about anywhere and run on just about any input power, single-phase or three-phase. Auto-Line™ senses input voltage and phase and instantly adjusts the welder to the optimal operational settings without manual linking. The simplified user interface with large 4.5 inch LCD display helps ensure proper weld parameters for your job. The Pro-Set™ mode eliminates the guesswork from set up by automatically choosing the most common weld settings for your application.
When using a water-cooled TIG torch, the 300 utilizes Cooler-On-Demand™ technology to save energy and prolong the life of your optional TIG torch and Miller Coolmate™ 1.3 cooler. It also comes standard with CPS (Coolant Power Supply), an integrated 120V dedicated outlet for running your Coolmate water circulator.

- Pro-Set™ feature (professional settings)
Eliminates the guesswork when setting weld parameters. Use Pro-Set when you want the speed, convenience and confidence of pre-set controls. Simply select the feature and adjust until Pro-Set appears on the display. The Pro-Set feature is available for Balance, Frequency, Pulse, and DIG parameters.
Provides state-of-the-art flexibility by automatically connecting to 208-575 VAC, single- or three- phase power without removing the covers to relink the power source. No longer is there a concern if you have the correct machine for the shop or the job site.
- Cooler Power Supply (CPS).
Integrated 120-volt dedicated-use receptacle to power the Coolmate™ 1.3. The power switch on the Dynasty also activates the receptacle to help prevent torch failure.
- Lift-Arc™ TIG
Arc starting provides x-ray clean welds without the use of high frequency.
- Blue Lightning™ TIG
High-frequency arc starter for non-contact arc initiation. Provides more consistent arc starts and greater reliability compared to traditional HF arc starters. Easy to set and increases productivity.
Operates the auxiliary cooling system only when needed, reducing noise, energy use, and airborne contaminants pulled through the cooler.
- Wireless remote compatible
Fully compatible with Miller wireless remote control solutions

This equipment is designed for outdoor use. It may be stored, but is not intended to be used outside during precipitation unless sheltered.AC TIG Features
- AC Pulsed TIG (0.1 to 500 pps)
Controls the amount of heat going into the weld to minimize warping or distortion, especially on thin material.
- AC Balance (30-99%)
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 WaveformsDC TIG Features
- DC Pulsed TIG (0.1 to 500 pps)
Controls the amount of heat going into the weld to minimize warping or distortion, especially on thin material
- Exceptionally smooth and precise arc
For welding exotic materials.
- Pulse Waveforms
Square provides a fast freezing puddle for ultimate arc control.
Sine produces a reduced audible sound and provides a more fluid puddle that is good for overlaying applications.
Triangular provides a quick-forming puddle while further reducing heat for thin 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.
Detects if the electrode is stuck to the part and turns the welding output off to safely and easily remove the electrode.
