Miller® Dynasty® 300 Multiprocess Welder 907819
The Miller® Dynasty® 300 Multiprocess is a 300 amp welder that is capable of stick, advanced AC/DC TIG welding and MIG welding. When paired with a Miller voltage sensing wire feeder, the 300 Multiprocess is the only welder you'll need on the jobsite to perform MIG, Stick, AC/DC TIG welding and air carbon arc gouging.
The Dynasty 300 Multiprocess has built in TIG pulse and advanced AC/DC wave forms and provides up to 300 amps of welding output. 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.
At just 55 pounds, the Dynasty 300 Multiprocess can weld materials up to 3/8 inch thick. When using a water-cooled TIG torch, the 300 Multiprocess 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.
IP23 rating This equipment is designed for outdoor use. It may be stored, but is not intended to be used outside during precipitation unless sheltered.

Features
Built-in CV circuitry
For MIG welding when paired with an OPTIONAL Miller voltage sensing feeder.
Easy-to-understand interface with 4.5-inch LCD display
Ensures proper machine setup and parameter selection
Informative on-screen explanations and dynamic images enhance the parameter selection process
Full AC features
Including advanced waveforms and wide ranges of balance and frequency.
Built-in pulser
Reduces heat input; adds arc stability.
USB Front panel port
Provides the ability to easily update software, back-up settings and transfer saved weld programs from one unit to the next.
Program memory
Allows easy naming, saving and recalling of favorite weld settings.
Deliver more productivity by eliminating the need to manually set the parameters
Deliver consistent quality by welders of all skills
Locks and limits
Provides control of weld parameter ranges minimizing deviation from the welding procedure specification (WPS).
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.
Auto-Line™
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.
Cooler-On-Demand™
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
IP23 rating -
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 Waveforms
DC 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.
MIG Features
CV output
Gives this unit MIG process capabilities when paired with a SuitCase® 8VS (or other voltage sensing feeder).
The feeder is powered off of the arc voltage of the power source and can run both solid and flux-cored wires
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.
Stick-Stuck
Detects if the electrode is stuck to the part and turns the welding output off to safely and easily remove the electrode.
