Miller did it. They really really did it. Dynasty280

[Brand X]

Well, I like my 300GTSW but it's on its last legs and the Dynasty 280's looking pretty good right now. Half the current draw too, which is more important to me than the waveforms. It would also be a better color match for the Coolmate 3 that the Thermal Arc is sitting on now.

Also considering the HTP221 because it will run on 120V and has more amps (on 240) than any other such machine. Decisions, decisions...

John

Not sure about half.. Never seen a larger Thermal Sanrex run close to it's rated amp draw. Must rate them at a dead short in stick mode. Always could could run over 200 amps on a 30 amp/ 240 volt circuit (GTSW/TSW 300) My MST 400 will run on a 60 amp /240 volt single phase circuit at very close to 500 amp mig output..

Funny,

I watched an Arcmaster 300 sell for $1200 on eBay last month. Except for the max AC frequency and the waveforms, it will do everything that Dynasty 280 will.

Never popped a 50 amp breaker with my Arcmaster 300. I still believe that a used one is THE machine to look for. Cannot beat the price.

Dammit! My bank account is still recovering from my recent MM350P Alumipro acquisition. Now all my excuses I've used the last 6 years for not buying a Thermal Arc 185 or Dynasty 200 are gone. Like many others, the +300 amp inverters are too much but the >/=200 amp aren't enough. Forget about all the great deals on used stuff because I'm single phase 240v ~50-70 amp max supply range. This whole time my poor little Econotig has been filling in for AC tig aluminum, might as well take the knob off because its permanently set to kill setting, fortunately I can't hold onto the air cooled torch much longer than the thermal shutdown breaker holds out. I need 1/4" + with a reasonable duty cycle which has kept me back from pulling the trigger on the TA or Dynasty so far. Yes the 350 Dynasty is the easy answer but my pile of cash always seems to end up elsewhere

Syncrowave 210 brother!

You smurf!

My next tax return hopefully the wifey lets me get one so it can sit in the garage and collect dust like my TB

I admit, I went into the LWS today & priced the dumbed down one.

Lets say I was quite surprised at the number & started to scheme.....

Duane & I both laughed & said we should buy one so we could brag about beating Terry to the punch on it

Really, at what dude quoted me, it's not entirely insane to think about possibly getting one. Of course, I need a Dynasty like I need another hole in the head. LMAO

Deep down, I'll always be a blue fan boy.....

Syncrowave 210 brother!

Thanks for the reply weldermike,

The Synchrowaves are very fine units, have several 250's at work that I play with once and awhile running on 480v 3-ph with water coolers. I would love to have one at home but that's the crux of the issue. The transformers are about as bullet proof as you can get but they take a lot of juice and weigh a lot. I've put in several bids on used 250's over the years with no luck so far. The old 200 and new 210 look very nice but other than all the parameters being adjustable they don't really have much more to offer than my old Econotig has. Don't get me wrong as that old girl is still the most used welder I have. In the last few weeks I've DC tigged some stainless, AC tigged some 3" aluminum flanged tee's and burnt up a bunch of 7018 stick on plain old steel. Its always been there for me but I just feel bad running it flat out on heavier aluminum. By comparison my Betamig and MM350P-Alum MIG units have life pretty easy. There is a place for a good multi-process unit in everyone's home, its just hard finding the right home for the ones available.

Five grand+ for the DX model.

Just put a little more with it & buy the 350

IMHO of course

The 200 is EXTREMELY capable and very portable. The 350 does not give much more capability and is much less portable. How often do you do aluminum over 1/4 inch and 200 amps will do just about anything except wire feed and carbon arc on steel.

Look a little further into it bud. Minus a/c stick its basically a plain dynasty, not a dx a little bigger and alot cheaper.

I have the 350 (which I love) but I would agree. Buy the 200, take the extra money and buy a 250ish MIG with a quality spool gun - used is OK. A Miller 251 or 252 would match nicely in case you are blue skinned

The extra 80 amps will take care of a ton of AC or DC work exponentially. On AC you will no longer have to wait to weld it. The alum will just glaze and you can start adding filler. I do agree, as far as portability the 280 can't do 115volts.

[awill4x4]

You'd need to save more than pennys over here mate....probably twice the price for it here.....

2 to 3 years ago I would have agreed with you.
I think Miller finally realised they had lost so much market share to companies like Fronius and Kemppi that actually competed in the market.
I know when I was looking at Dynasty 350's a couple of years ago the price was over Aus $8000 for power source only and when I bought one (power source only) a month or so ago I paid Aus $6700 inc GST.
Dynasty 200 machines are now priced significantly below those of Kemppi and way below Fronius.
