Description
The Dynasty 300 Series now goes beyond top - notch TIG and Stick performance. Its additional CV output enables MIG welding, making it a great fit for shipbuilding, construction, mechanical contractors, and educational institutions.
Intuitive Interface LCD Display
Get clear on - screen explanations and dynamic images to set up the machine and select parameters easily.
Program Memory
Save, name, and recall your favorite weld settings effortlessly.
Pro - Set Feature (professional settings)
Take the guesswork out of setting weld parameters. Select this feature and adjust until Pro - Set shows on the display. It works for Balance, Frequency, Pulse, and DIG parameters.
Locks and Limits
Control weld parameter ranges to stick to welding procedure specifications.
USB Port
Update software, back up settings, and transfer saved weld programs between units with ease.
Auto - Line™ Technology
This inverter power supply supports any single - phase input voltage (208–600 V) without manual linking. It's great for jobs with dirty or unreliable power.
Stick Features
Adjust arc characteristics with tailored arc control (DIG) for different applications and electrodes. The Hot Start™ adaptive control ensures positive arc starts.
MIG
The CV output of the power source gives MIG capabilities when paired with an ArcReach® 8 or 12.
Blue Lightning™
A high - frequency (HF) arc starter for non - contact arc initiation. It offers more consistent arc starts than traditional ones.
Cooler - On - Demand™
Run the auxiliary cooling system only when needed to cut noise, energy use, and airborne contaminants.
Fan - On - Demand™
Operate the cooling system as required to reduce noise, energy use, and contaminants.

Accessories


Using the Miller Dynasty 300 AC/DC Multiprocess Wireless Air - Cooled Welding Machine is straightforward. First, use the intuitive LCD display to set up the machine and select the right parameters. You can save your favorite settings in the program memory for quick access later. When it comes to welding processes, this machine supports AC/DC TIG, pulsed TIG, stick, air carbon arc, MIG, and flux - cored welding. For stick welding, use the tailored arc control (DIG) to adjust the arc for different electrodes. The Hot Start™ will help you start the arc without sticking. For MIG welding, pair the machine with an ArcReach® 8 or 12. Remember, when using the Pro - Set feature, select it and adjust until it shows on the display. This will save you time and give you more confidence in your settings. Also, take advantage of the Auto - Line™ Technology, which allows you to connect to any single - phase input voltage from 208 to 600 V without manual linking. As for maintenance, keep the machine clean. The Cooler - On - Demand™ and Fan - On - Demand™ features are designed to reduce noise, energy use, and the amount of contaminants pulled through the machine. Use the USB port to update the software regularly and back up your settings. Make sure to follow all safety instructions and check the spec sheet for detailed technical information.
