    Default Aerowave vs Dynasty 350

    I haven't bought a TIG welder since the 330 Airco/Miller I got used in 1972. It seemed to always do what we needed to do, and the selenium rectifiers in it are still doing fine. (self healing, you know) If we had anything difficult, we sent it out to somebody with a good synchrowave and a steady hand and were always pleased with the results.
    Lately, we've been asked to do a lot of difficult stuff, primarily 1/4 aluminum. It's welding we had no hope of doing in house, and we haven't been very pleased with what we've gotten back. Much of the problems are design related, which we don't have too much control over. Prints show things like a 10 inch long strip of .060 alum welded at right angles to the center of a 1/4 alum plate, with a 3/16 fillet welded specified. I don't like having to tell a customer "we can't do that."
    So we've been considering investing in equipment and taking some of that work back in house, to get better control over the results. None of our outside welders seem to think that there is any sense going beyond the
    synchrowave, given their mix of work.

    Anyhow I've been searching around for somebody with a Dynasty 350 who would let me play around with it, and the best I could do was that a friend had purchased an Aerowave in 2000. I spent about a half an hour with it on Saturday, and I was completely blown away. What an incredible difference.

    I've probably only welded myself for 10 or 12 hours in the last year, since most of the time nowdays I sit in front of a computer, but within 2 minutes I was running 3/16 - 1/4 beads on 90 degree intersections between 1/8 and 1/4 aluminum. (3/32 2% cerium, 220 amps fwd 120 amps reverse 300 hz) (at max pedal, which I didn't need) These weren't outside corner welds, but T intesections. (easier to manipulate, but harder to get the heat) I found the difference nearly unbelievable. Since I'm out of practice, to say the least, I found especially nice that when I dipped the tungsten a bit, instead of a huge black cloud, the mistake was barely noticable. I wish I had brought along some .060 alum to try to weld to the 1/4, but I didn't bother, since I assumed it would be not possible.

    So my question is: Since the Aerowave isn't available any more, how good of a job did Miller do with the Dynasty 350 to replace it? Is there anybody out there who has had experience with both?

    I don't remember the specifications exactly, but I believe the Aerowave has more adjustability than the Dynasty, near as I can figure from the on line manuals. I think the Dynasty hides some things a few menu levels down, that can be done with a button push and a knob twist on the Aerowave. In my experience, anything too hidden won't get adjusted, and the advantage of the control is completely lost.

    The other end of the extreme we have been avoiding is the very low end on thin stainless. How does the Dynasty 350 do on welds like 5 to 10 amps DC on 22 ga polished stainless corners? I know friends are routinely using less than 5 amps on some of that work (no rod), and that's below what the Dynasty 350 is rated for, though the Dynasty 200 says it goes to 1 amp.

    Anybody out there with experience with both? Comments appreciated.

    I too am sorry I cant help you, I have a Dynasty 300 and I think its the cats meow compared to the 250 synchrowave.

    What I can tell you is that I dont mess with the controls on my dynasty too much, theres more control than I could ever possibly use.

    I found what I will call the sweet spot for the majority of my work and I dont go one way or the other to far outside of the sweet spot zone.

    If I were to take a guess I would say the aero wave has a little more adjustability.

    But thats only a guess.

    We have both Dynasty 300's and 350's at work. I haven't had a whole lot of time on the 350 yet but it seems to work just a little nicer than the 300 and the 300 is a great machine!
    Unfortuneatly I have no experience with the Aerowave so I can't be of any help comparing the two.

    The controls on the Dynasty were derived from the Aerowave. I just looked back thru the manual for the Aerowave, and the only things that I could see that the Aerowave did that the Dynasty 350 will not is that the Aerowave could control the time in your initial amperage value while using the sequencer (used for automation). You actually gain this ability back while hooking up the automation interface kit for the Dynasty 350, but like I say it is typically used in automation applications. The only other thing that differs is that the Aerowave went down to 1 amp and low end, and on the Dynasty 350 low end is 5. These are the only differences, other than the Dynasty having the ability to adjust some of it's features far beyond what the Aerowave was able to.

    Some of the New things that the Dynasty has that the Aerowave did not.
    - 36 savable programs- 9 for each polarity and process
    - 4 different waveforms- Triangular, Adv Square, Soft Square, and Sine Wave
    - Ability of using the sloper while using the spot feature on the machine
    - Dynasty 350 will spot time for 999 seconds vs the Aerowave's 30 seconds.
    - Adjustable OCV for stick welding
    - Dynasty is smaller and about 200 lbs lighter and is capable of nearly the same output (Aero-375A, Dyn-350A)
    - Dynasty 350 is Auto-Line equipped. Easy to hook up to your power, power savings, and smaller circuit breaker size
    - Dinse adapters make it easier to hook up leads

    These are just some of the benefits that I thought of. There are probably more. In short,,,, The Dynasty will do everything that pretty much any user would ever need it to.

    The Dynasty 350 is quite a bit better not only in features but also design. Back in the Aerowave days, the complexity of the machine due to the lack of custom or high power fast switch devices, demanded that we create the "hybrid" welder. Now that technology has stepped up to our design requirements, the Dynasty 350 is much more versitile and easier to build and repair.
    The Dynasty has more wave shape selections than the Aerowave's pure squarewave and is easier to set and run than the Aerowave when you need to make amperage adjustments. There is a bunch of memory locations you can program different jobs to and it's way more portable.

    When I get enough saved, I'm getting one also.

    Hope this helps.

    A couple years ago b-4 we got a new dynasty 300 at work we were checking pricing on various welders. Our lws pricing on the 300 was about 5600.00 w/cooler & cart. They said that they might be able to get an aerowave yet(back then) but the price for one of them was pushing 10 grand.

    A sure sign we've accumulated too much junque when I can't remember who made what we've got.

    Our orbital tig is French "Polysoude", not the Swiss "Soudronics."

    Sorry for the mistake.
