  • Miller Dynasty 300DX

    Hi,

    I am looking for a Miller Dynasty 300DX (the last model produced)?
    Needs to be in very good condition.
    Anyone have one for sale?

    Thanks,
    Erik

    unless you find one in extremely good condition, like new. I'd be picking a different model

      Dynasty 300DX

      Hi,
      I was looking for a Dynasty 300DX because they are more portable than the 350's.
      I thought they were very reliable and good. I am not sure if there is a 350DX that is as portable as the 300? I have a 200DX and a 300Dx (older model with dials).
      Both are good but the 300DX does not have a pulse or some other settings.
      This is why I am looking to upgrade.
      You mentioned to only purchase one that is in very good shape; is that because they are expensive to fix or not reliable once they have been pushed hard?
      Thanks,
      Erik

        The welders themselves are pretty portable... it is when you add the water cooler, cart and argon tank... they get awkward...


        You may want to take a closer look at the weights of just the bare power supply..... it may give you a different perspective on portability..

        here they are:

        Dynasty 350DX 135lbs

        Dynasty 300DX 110lbs

        Dynasty 280DX 55lbs

        Dynasty 200DX 48.5lbs


        The current model in the top slot for portability is the Dynasty 280DX...

        if that is more than you want to pay...

        why not the Dynasty 200DX??... they are much more capable than the 200 amp rating suggests.. especially if you go to a Helium mix to gain more effective heat..


        Somewhere here there is a thread where Shovelon welds 1/2 inch Aluminum plate with a Dynasty 200 from a few years back..

        BTW... there is a Syncrowave 350... not very portable @ 695 lbs

          Well the 300DX is an OLD machine, parts if you can actually get them are Huge$$. I don't know how many I've sent to the bone yard, but is is MANY. That is why I said find a different machine. I would NEVER consider buying one. They are pure headache to work on.

                You mention a Syncrowave 350 I can live with weight, and bulk. A very nice Syncrowave with bells and whistles can be had for $2500. A Dynasty 280 is $6000. Would I be happy with the performance, or still lust after the Dynasty? The power hungry nature of the Syncrowave is a deterent, but in my case not a deal breaker.

                  Once you have tried one....

                  The Dynasty Lust tends to grow and fester until you break down and get your own....

                  They have different weld characteristics....

                  The Sync is head and shoulders above a sinwave machine like a Dialarc or 330...

                  and the Dynasty is Hans Solo's "Milenium Falcon" compared to the Syncrowave as "55 Chevy"...

                  The Sync is a great machine... but bet you will start to save for a Dyn in short order...

                    Would you buy an unused Dynasty 300 (newest model) for $5000 cooler and cart included or pay the difference and get the new Dynasty 350?

                      I Did Buy The DYNASTY 350DX Tigrunner....

                      NO Regrets...

                      Dyn 300 is an old machine, old design with known service issues and NO Warrantee...

                      The Dyn 350 is more highlty developed with more features.. Excellent reliability history..

                      AND 3 year Warrantee...

                      Miller inverters have evolved a lot as a continual process of improvement.. with the jump from Dyn 300 to Dyn 350 being a huge leap...

                      BTW... have seen several Dyn 350DX Tigrunners come up used in the $4600 range..

                        H80N,

                        Got any leads or links to where one of those used Dynasty 350DX's can be had in the $4600 range? All I've got to work with right now for a TIG machine is a Syncrowave 250 and I've been wanting a upgrade to a Dynasty for some time now.

                              Sorry H80N, I didn't watch any of the videos but I cant believe there's any thing better than my Dynasty 300, You guys are acting like its an antique when its leaps and bounds better than a Synchrowave.


                              I'm also surprised that Cruizer acts like its a 25 year old machine when I just bought it new a couple years ago.
                              ( Okay maybe 7 or so years but I have never had a problem with mine)

                              I hope Cruiser is slightly exaggerating on not being able to get parts because 7 years old is still a new machine when I hear Pipe line guys talking about the Lincolns from the 70's still being a valuable machine.

                              I had to go into a Ford plant this morning to weld on a Stainless steel leak test chamber, Where they use Helium to check plastic gas tanks for leaks.
                              Guess what they had ( A Synchrowave 350 )

                              I However used my Miller STL150 to weld it up.
