    Yours sounds like it has given good service over many years....

    hopefully there are some tips to keep it going for a long time more...
    I've been studying everything I can find about the Dynasty machines. I know, I ridicule my best friend who buys many thousands of dollars of ski equipment convinced the next purchase will make him ski as well as me on my used equipment. I'm a hypocrite, I know it! I NEED a Dynasty. I'm worried a 200DX might not be enough, so I am leaning toward a 280DX. Then I check prices on a 350. Surprisingly, The 350 isn't much more cost than the 280! It seems to have more adjustments, more duty cycle, more power. Is it only more heavy than the 280?

    I will admit to being prejudiced...
    BUT... if I could keep only one welder it would be my Dynasty 350 Tigrunner...

    the Dyn 350 Tigrunner has been a shop only machine..(268lbs)

    the Dyn 200DX gets dragged around..

    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..

    We had a busy day in the shop today, one machine was air arcing, I was welding with the miller matic vintage and I needed a third welder for my other guy.

    I have 8 welding machines and still came up short, time to by another mig.

    Not a big poster, but must defend the 300!!

    I have friends who have the 300 who never had and issue and I love my 300 and have never had an issue.

    The weights tell the story, in my opinion. The 300 is closer to 330 in output - my SWAG, but when I weld thick, for me at .5 to .625 alum and have used my syncrowave 300 (40 yr old machine), the Dynasty 300DX and a syncrowave 350LX, they all weld the preheated material nicely Although the Syncrowave 300 has more pedal avail, far beyond its rated 300 amps.

    It would be a hard decision if I could only keep one. Although the wife is badgering me lately, something about installing a floor....err

    The 300 dynasty is a fine machine and with performance that appears beyond its rating, seems to be the deal.

    It's been a few years since I have been on this fine forum, I have also had a Dynasty 300 with all the bells and knock on wood I haven't had a lick of problem with it, It sure was a nice upgrade from my sync 250's. I don't disagree that the 350 version has some nice upgrades but for me it wasn't worth making the switch Yet!

    It's too soon to tell about life expectancy of the Dynasty 280 DX, about the performance I can say it's the best machine I'm aware of. I am curious about amplitude adjustment as in the 350 DX. What does that do?

    I think the 280 has a higher duty cycle than the 350. At least in the specs given by Miller ( I've checked them several times just to be sure because I couldn't believe it ). I am nervouse as to being made in the 200dx size, can it cool well enough to be dependable being that small? I believe in Miller's quality, but man, you've got to wonder. How about an Esab ( sorry Miller ) heliarc 281i. The duty cycle is 100% @ 250amps. I do not think it has the adjustments that are offered on the Dynasty's and only is 220V and heavier I think but GREAT PRICE as well.

    -Yep the ESAB is ok, Cheaper, and likely works just as well, However, things break, its enevatible. ESAB parts have to come from Europe, so thats a month right there. warranty centers trained in repairing ESABS are few and far between Tech support is pretty much zero, and even if you do get through, the techs generally don't have a clue about much, other than what they had for lunch or the weather.

    I'm a ESAB warranty tech, and hey while I spend lots of $$ in training, I rufuse to do an ESAB warranty. I hate the part waiting, I hate tech support ( I can remember last asking a technical question on a Subarc, they told me to read the owners manual) I had choice words for them shortly after they said that!

    Say you brand new machine scews up and crashes in the first 20 hrs, Miller and Lincoln will replace it. ESAB, nope, and your down for quite along time. Many times the Big 2 will replace it it still in warranty. ESAB not a chance in ****.

    Moral to the story, is to buy the Miller, as you will be much happier.

    How about a Dynasty 300 for $500 that looks to be in good shape. Would love to buy a 200 new, but don't have the money to do so. I do have an old dialarc 250 hf machine that is giving me a lot of trouble and need to upgrade.
