which tig machine

[kamaroman68]

If one had the chance to own a miller synchrowave 200 dx or a miller 200 dynasty tig machine which one would you pick and why? I kind of like the portability of the dynasty but it doesnt seem to me very industrial like built. This is for a home shop. Thanks Chris

Tell us about the features of each:

Balance controls? Pulse? Post flow timer?

From what I know, the Synchrowave is hard to beat...

What are you welding?

For aluminum, the inverter welders win hands down. I've also heard of life span issues with circuit boards, etc. We use a water cooled Synchrowave 250 and an air cooled Synch 200. Considered trading the 250 for the Dynasty 200, but tough to justify the additional $$$ since the 250 is a great machine.

[kamaroman68]

I was actually hoping for an all around machine. SS, aluminum, mild steel.

JP I am having trouble setting up links to the 2 machines. Thanks

How do you like the synch 200????? Chris

I have a 351 Syncrowave. Although it has been a few years since I have used it (not enough power in the current shop yet) it is a great welder. The only downfall for me is it requires 200 amps.

Take a look at the current requirements of each. The inverter based Dynasty welders are a lot more efficient and only require roughly half the supply current of the transformer based syncrowave machines for a given weld current. This can be an important factor in a home shop. I also recall that the Dynasty has more capabilities and adjustability than the Syncrowave 200. That may or may not be a good thing for a novice welder in a home shop.

Miller is pushing the Diversion 185 for home shops. It is an inverter based machine which uses the default settings of the Dynasty 200 DX.

For a home shop I would consider the HTP Invertig 201, water cooled.

Very nice unit I have spent a lot of time on.

[MonzaRacer]

http://www.thermadyne.com/ also makes a few good units

For the cost of the complete packaged dynasty dx, you could buy a syncrowave 250 which is a better machine than the dynasty imo.

(snip) syncrowave 250 which is a better machine than the dynasty imo.

In all the years the dynasty's have been out, that's the first time I've ever heard that accept from old guys who were scared of all those buttons...

So, what is it that you like about the syncro over the dynasty? Is it the huge amount of input power that they suck up? Is it all that floor space they take up?

Maybe you like the lack of: a pulser, sequencer, frequency adjustment, soft start, the ability to plug it into ANY power source, non-constant high frequency in AC, broader AC freq range, etc.

Can you do a full pen, single V butt weld on 1/4" 6061 and keep your weld width to less than 3/16" in one pass with your syncro? I bet you can't.

I just got done welding some fuel tanks for Boeing, and I can tell you that doing what we do at work with a syncro would be downright laughable.

So now, let's hear why prefer the syncrowaves over the dynastys. I'm on pins and needles.

And Chris, dynastys are about as bulletproof as TIG machines come. I run them everyday and have only had one problem; We had a processor board go out one day. Big whoop...Miller had it fixed 9am the next day. That's why we spend money on the blue machines. If you take your welding seriously like you should, then get the dynasty. Then get yourself a 350P. :D

With the excection of the auto link,you can get a syncro with all those options.
I did try to do exactly what you said i couldn't do and your right.But i find it hard to believe the dynasty can.
Some questions for ya on that one.
Gas?
Tungston size?
Heat?
What kind of bevel?Any landing?
Got any pics?(of the weld)
Like i said,i never used a dynasty machine,So im ignorant on what there capable of doing.I like to learn new stuff everyday,just don't be an ******* when you teach.

Very true, but with all those options, how much would you save over the base price of a Dynasty?

- Gas was 95% Argon and 5% Helium, certified. Purge gas was certified 100% Argon.
- Tungsten was 3/32" Lanthanated ground to about a 60º included angle with a roughly .020" flat
- I'm not sure of the amperage... The machine was maxed at 300 or whatever but I never had the pedal floored.
- Double bevel at 50º included angle with a 1/16" land. All bevels were machined.
- Pulser was at something like 150pps, 85% background and 90% peak time. This was only to keep the arc more stable, otherwise it wanted to bounce side to side a little too much.
- Filler was 1/16" 4043

EDIT: I forgot the most important part. AC balance was at 88% (!) and frequency was at 250Hz. That's where the real magic happens.

It was for a big aerospace company so no pictures. Each weld was cleaned with alcohol, then scraped, then wiped down again with lint free rags. Run on and run off tabs were used and then machined off, then each part got x-ray'd.

just don't be an ******* when you teach.

Why do you insist on spoiling all my fun?

Off topic, but I noticed Matt took a break for a while (after a job transition?). Is RFR back?

First,i'm really not that old.Second,buttons don't scare me either.
Personlly i've never used any dynasty machine.But i have used other inverter based machines,and there ok.The syncro 200 is a very capable machine for the money.We use 250s at work and there great machines for what we do.
If you make laughable welds with any machine you use you shouldn't be welding.

[JRouche]

If I had the bucks I would buy the Dynasty in a second. They are great machines. But the synchro will do just fine, for basic welding, no bells and whistles. And lemme say, I would love to have some bells and whistles at this point. I have a Hobart tigwave 250 and it is a great machine, but no bells or whistles. Its basically just a large power supply. It does have a low current though and that comes in handy. But from what I understand the Dynasty has a really lower range. Compare it with the synchro, it may be better at controlling lower currents and many times folks forget to look at the small end. For example, look at a really cheap imports from harbor freight, its lowest current level my be 15 amps. Hard to weld beer cans with that The synchro may be 5 amps but I remember reading years back the dynasty was 3 amps. JR

So every inverter "based" TIG is exactly like a Dynasty? Wow, I was not aware of that.

The syncro 200 is a very capable machine for the money.We use 250s at work and there great machines for what we do.

I agree that the Syncro's are very capable at a lot of things, but saying that they are great "for what we do" means absolutely nothing. What do you do? What we do is aircraft parts production, and for what we do, the Dynasty's offer incredible accuracy and stability, plus speed and versatility. None of which are traits of the Syncro's. My very first TIG setup was a Syncro 180SD and I have fond memories of that little guy, but these days I absolutely hate running anything other than an inverter.

If you make laughable welds with any machine you use you shouldn't be welding.

Don't lash out just because you're outgunned. (Ok, now you can lash out because I'm an ass) Who said anything about ultimate weld quality? I can run X-ray quality welds with either machine any day of the week, but with a Dynasty I can do it a whole lot faster and with less fuss.

Also, please note that I never said that a Dynasty is the best choice for Chris. Only he can make that decision. I just took issue with your statements.

[parsonsj]

Uh, hi Matt.

Welcome back. Why the attitude? No need to be so harsh. It seems that the Dynasty is a better machine since it's an inverter-based technology. Good info.

No need to say anything else.

Funny, I was about to edit my post and say how much I enjoyed riling the mods up.

I'm not back. You know, the only reason I left this joint was out of respect for Larry. I love that dude and respect the fact that my personality doesn't jive with how he wants his message board to be run. You should know that I can't stand misinformation and people spreading the **** sandwhich that they call an opinion around like it's a fact. I've done nothing but get worse about this over the years. My disdain for the human condition is at an all time high, and yet, if you can handle a little sarcasm, you might just learn something.

What's funny is that I know there's atleast a few people that like to see me put somebody front and center. Usually I only come here when one of your members emails me about a thread that they think I could be usefull in.

So with that, I bid you all tootles once again. I'll check on you guys in a few months. Be good boys and girls and do what you're told.

Edit:

No need to say anything else.

I disagree whole heartedly. People shouldn't put a lot of faith in somebody simply saying that one thing is better than another. No sir, facts, specs, and whatever other information is required to make a solid decision on things like this. With presenting facts comes disproving some opinions. Would you disagree?

I just do it with a little flair. Do I atleast get showmanship points?

Hahaha.. Yup, yer a weldor. Ive been working around metal (sheet metal mechanic, fancy for grunt) for a few years now, and weldors (which I am not). But work with them. And my bro in law was a weldor at san onofre, my cousin is a union iron worker, and Ive enjoyed the personalities. Rubs some folks the wrong way, hell!! Not me. Guess a guy working in the office all day with a room full of women might be used to the civil water cooler talk (not saying anyone here, all men right??) might get offended. Not me. I dont get ruffled by much. OH!! Unless you talk crap about my crappy welding LOL.. No, I like some strong opinions. Milk toast anyone?? I dont drink milk or eat toast so thats where Im at. Welders?? What ever you can afford, buy the most you can afford. If its a buzz box and some soggy sticks, then thats gonna work, it has to. JR
