We have been welding with the new TIG Runner for a week now.
In my 40 years of welding, I have always used Miller welding machine, from Trailblazers to TIG Runners and everything in between. The bottom line is they're the best. I would also like to thank everyone at Miller Welding for all the help. I would also like to mention the Tech-Support Staff at Miller Welding. Extremely Helpful, Informative, First Class. Best Regards. Mike
Buy once cry once!
This machine is so smooth. The interface is easy to use even with the vast amount of adjustments available. Wireless foot pedal is a game changer, saves time and frustration.
Top tier welds. Top tier machine.
Best machine on the market. Nothing in my opinion comes close to welding with a dynasty. Expensive yes, worth it. Also yes
I just had to have one for myself
I bought a Miller Dial-A-Arc in tig welder 1980 and after 44 years it was time to get a new one. In the process of getting welding certification at school I ran a Aerowave and after running the Aerowave at school I had to have one at work. I then demoed one of the first ten Dynasty at work and bought Dynasty 350, 700, 280 and another 280 Dynasty. The Dynasty welds challenges your background of welding knowledge and giving you the edge on controlling the weld. For example I welding for work 3/8 dia. aluminum tubing with a .028 wall to seal and maintain minimum drop through. Now retired working on old cars it was hard to justify this Dynasty 300 but I just could not see getting a welder that was just good a nuff.
Without a doubt one of the best!
Nice solid welder for Aluminum TIG welding! Been running Miller Dynasty for 15 years and counting. Top notch!
Awesome machine
The machine is awesome lots of adjustments if you need it only thing I didn't like was after spending that much I still had to order a flex head torch afterwards as it only comes with a solid.
10 out of 10. Great machine
Nothing bad to say about this machine. It's a perfect fit for my shop environment. Crisp clean starts with the high frequency. The lift arc starts almost feel intuitive, and the stick welding runs 7018s like it should. I have plenty of control over how the arc behaves and I can make presets for less experienced people in my shop. No regrets
Absolute Poower house with incredible support to boot!
We haven't had our Dynasty long but man! Its an absolute powerhouse! The Bluetooth foot pedal is incredible, with no lag and it's super responsive. The operations this thing had is amazing. Being able to wire it 1 or 3 phase is great and gave us options. Now having the ability to tig aluminum with the ability to change HZ (20-400HZ). And to top it ALL of Miller's customers/ technical support is fantastic!
Replaced an older Lincoln welder with this one. Great move!
We use this welder in our daily production. I don't do any welding myself, but my employees do and they love it. We replaced an older Lincoln welder with this one. My guys are sold!
I have 4 of this machines now
This is a good machine i really like it
