value of used dynasty 350

Postby sru_tx » Thu Aug 10, 2017 5:55 pm

Yes, I'm still perusing Craigslist and hoping to find a used Dynasty. I can't help myself :lol:

In general, I'm looking for an inverter Dynasty over the bullet-proof Syncro due to its variety of pulser settings that would be useful for welding thin metals. I also weld aluminum on occasion so a water-cooled torch would be nice. Considering I have max'd my 200AHP a few times, I would prefer a 280DX sized unit (don't want to mess w/ having helium)

I came across a 10 year old Dynasty 350 w cooler. Don't know the hours yet. I realize pricing is definitely regional but any opinions on what would be a reasonable price? ($4K? $5K?) I see Syncros go for $3k around here. The 350 is a bigger machine than I need but if the price is better than a new 280dx setup why not?

{perhaps this is just a plea to get talked off of the ledge and go back to working on skills :roll: }

thx.

Hey Steve
Fill me in, are you doing work on the side or do you have your own shop??

10 years old, I'd want something newer I think unless the price is really good, especially if you have customers depending on you.

In your area (Houston) there should be welding suppliers that could help with a estimate on a used machine, or tell them to contact you if they hear of a machine for sale.

If you buy a used Dynasty, ideally you want to get a unit newer than a 2010 model. It is my understanding from Miller that was when they introduced their different waveform software. A 10 year old unit won't have that feature. It will still be a great machine will ample frequency controls, but I would opt for the wave packages if I were buying a used unit.

Good luck finding a used 280DX for anything less than near regular price. They're pretty new and unless someone is hurting for cash, they're like hens teeth. I have a 12 year old 200DX that still runs great so I have nothing but strong recommendations for them.

hmm, seems like my previous response attempt didn't post....

Richard,
Some might call it an expensive hobby but I see it as a business.... just not a very profitable one :lol:
Truth be told, this is my second or third career. Don't really see it as an early retirement. I was the breadwinner for a long time, my wife is now making the bread and she said to go find something I enjoy.

I'm making unique furniture out of metal and wood. Curvy swoopy pieces. shaped sheet metal. Tubular steel bent on a ring roller. I do some aluminum. I've made a few gates and awnings for myself and wouldn't mind finding a client for some of that either. I do a few commissions here and there. I've only been selling my stuff for about a year. Learning skills as I go.

cj737 I realize a used 280DX is a unicorn. A more accurate statement is I want something with a little more juice than 200A machine without having to deal with helium. I'd like waveforms which eliminates the HTP.

Honestly, I've got upgrade-itis thinking a machine with waveforms and high frequency pulsing capability would help me with some of my pieces that I make out of 18 gauge CR steel.

My suspicion is the asking price is too much for 10 y.o. machine and a better choice for the money is a new 280dx and add the cooler later OR an Everlast w cooler.

thanks.

Aren't inverters commonly getting end-of-lifed at around 10 years old? It's like asking $3k for a Windows 386 with a 160MB hard drive.

Honestly, just grab a new 210DX and use a single bottle of 75%Ar/25%He premixed from your local gas supplier. Solves the need for thick aluminum, won't hurt any of your welding of steel, and is not that much more expensive than 100% Ar. If you get into thick aluminum, you can preheat it with a torch anyway to reduce the requirements of amperage. And if you're "hobby welding" anyway, you don't need the ability to run 250+ amps on aluminum.

My recommendation. :)

Thanks for the input and talking me off of the ledge :lol:

I need to put the Internet down and walk away... for my own good.

A 10y.o. Dynasty's functionality is not quite in line with the newer units but still pretty good. The main rub is that it may work fine at the moment but the expense of a repair is a big gamble. The common sense thing to do is to get a smaller model (210dx) with a warranty and just add helium for the rare occasion it's needed. If I find I'm doing more work on thicker aluminum I should be making enough money to justify a bigger machine, but until that happens.... helium.

thanks.

Well it could be that someone wants to weld a few thick parts, just wont need to weld them back to back. So they won't need a super massive duty cycle, but they would still need the amperage. One doesnt need to weld structural parts to want to want perhaps some heavy duty shelves or brackets or something similar. Telling a hobby welder exactly what it means to be a hobby welder doesn't make too much sense to me, as it has nothing to do with the size of the part. Just means he/she isn't doing production welding and/or doesn't need to do it for a living.

Oscar, I think you raise an interesting point. What exactly does "hobby" mean?

In my original post, I jokingly called it a hobby in the sense that I'm not turning a profit yet. I've bought equipment, filed LLC, business cards, rented spaces at markets over the course of the last 12 months. I've sold furniture of my own design, been commissioned to make other peoples' visions, made gates, kayak racks, etc.

While I am enjoying myself learning skills, being creative, and meeting people, I don't consider it a hobby. A hobby is something done in spare time (golf, fishing, hunting, art, music, cars, making things, whatever) with no realistic expectation of monetary sustenance. A hobby is not necessarily defined by the size of the project.

Turning an avocation (hobby) into a vocation is a dream for many but not mine. For me, they are two separate entities.

I meant no disrespect regarding "hobby". As for amperage required to weld thick parts, it's only required for "single pass" welds. Seriously thick steel you could easily stick weld with your Dynasty (they stick great by the way) and for aluminum, preheat, multi-pass, or pure Helium on DC works too. Plenty of routes around the rabbit hole to limit the need for 250+ amp machines for the occasional welding job.

Sure enough, if your business takes off and you need the range and duty cycle, step right up and grab a new Dynasty 400! I'd come visit regularly to ogle it ;)
