Dynasty vs. Syncrowave

[rlitman]

Vertically, yes indeed. I'm probably the only one crazy enough to have done this.
It's strapped to a hand truck, with a steel hoop holding the argon bottle next to it, and the torch lead winds up around a pair of hooks on the back.
Because of the way it is strapped into a cradle welded to the back of the hand truck, the back of the machine (which is on the bottom), hangs almost a foot above the floor. It kind of looks like a side by side oxy/acetylene cart setup.
I save a LOT of floor space that way (vs a traditional cart design), and it's still easy to move around.
It is also nice having the display and knob facing up, but you do have to reach under the machine to get to the switch.

Seems to me if Miller had wanted the Dynasty 200 mounted vertically, they would have put feet on the back of the machine.

The front of the machine has louvers to prevent anything liquid or even solid from simply dropping into the machine. When you mount it vertically, you've basically defeated the louvers. Much more susceptable to dust also.

Also disagree about the pulser on the Syncrowave. One of the main reasons I upgraded from my previous Sync 250 to the current machine was because of the ability to field install the internal pulser. My Sync 250 did not come with the pulser (optional), but it was the first thing I added.

Slow speed pulsing is what pulsing was originally all about. With slow speed pulsing you have (and can see) the high amp (melting)cycle and the low amp (freezing) cycle. Works extremely well with thin wall SS tube. Actually, you can even determine the lower "average" heat put into the weldment vs what happens with high speed pulsing. High speed pulsing (>120 PPS) does "agitate" the puddle more, but has a different effect on the average heat input than does the slow speed pulsing.

Slow speed pulsing (Syncrowaves) definitely has it's place, especially on thin SS and mild steel. If it didn't have a place, I suspect you wouldn't have that same capability on the Dynasty series.

Well more power to ya if you can find a use for 10pps. I really don't want to see anything but productivity, and slow speed pulsing only slows me down. In fact I could only take a few minutes of it before I wanted to shoot myself because the frequency gave me eye fatigue on an industrial strength level.

Anything under 5pps I have a foot control for.

Shovelon,

Different scenario, different goals.

You're looking for "maximium production", I'm looking for "optimal results".

I (and I suspect many of our other tiggers) are looking for a way to get the best results in a given situation. We're not in a race to see who can get things done. Heck, if speed was foremost, I'd probably just weld it up with pulsed mig.

One thing about the Dynasty it does make quite a buzzing sound that the other old tig machines that i have run never did

Probably not pulse but the frequency it was being run at

Hello all, I have watched this thread with interest. There have been many offshoots associated with the original topic and I feel that all of them have pointed out various needs/reasons for whichever choice or selection that an individual might choose to make.

On the one hand you have the reasoning of power consumption issues, Dynasty likely comes out on top in that area, yet with the associated price that might have a lot to do with justification for that choice or not.

Price and general availability would likely favor a Syncrowave choice, yet, depending upon the sort of deal that an individual stumbles upon, not always, you might still come upon a once-in-a-lifetime deal that puts the Dynasty in your hands.

Then you have tradition, no matter what the benefits or other influences there may well be, there are those who are molded into the comfort/capabilities of a Syncrowave and there is no other choice.

You are going to have a myriad of different perceived needs and applications of GTAW/TIG welding that everyone is trying to address with their particular machine choice. Thus, there will be pro's and con's for each individual that will drive and support their choice.

A crystal ball would be really nice to have when we start planning on outfitting our shops with all of the machinery needs that we perceive to be on our horizon. Only then could we possibly go about doing so without making a mistake or two and be completely efficient at that task. Short of that, we all go through different rituals and lines of reasoning to accomplish the task.

I do wish to say thank you to everyone who posts on this forum, as the views and trains of thought, lines of reasoning and justification all make for some informative and interesting reading. Thanks folks and best regards, Allan

Yeah that disturbed me a little when I first ran the machine. I definitely does have more "bells and whistles" in both meanings.

From a Hobbyist NOOB tigger point of view...Neither of those are a good choice if you get them new, they are to expensive to just have fun with A Diversion or a used Synchowave are more budget wise... As far I'm concern any TIG capable of welding 1/4 Aluminum or steel can fill all my needs as long it's Blue

No such events with Dynasty.

Some of us with older Dynastys it still an issue. Mine has points under the cover.

We have a new Sy 250 DX with all the options. It's a great machine and I have been exploring the pulser. It does work nice at low pulse especially on thin SS. I even have used it on thin aluminum.....040 and .030. Makes a difference. the AC balance works nice too. It allows a smaller electrode for a given current if you have very clean and tight fitting joints. It a very stable machine and works right down to 5 amps and less. Equally at home on 250 amps on steel or aluminum.

The pulser works nice but after years of "fake pulsing" with the foot pedal it takes some getting used to. Being 70 yr old my timing and reactions as well as the steady hand have deteriated some. haha At higher rates it tends to lessen the total heat input but you have to move right along or there is no advantage. We have measured the heat transfer in moly tubing both with and without pulse so you can see the results. It's great for agitating the puddle too when necessary.

It take a huge amount of current out of the wall. We had to install a dedicated 100 amp service to get it to work at full power. I would not recommend one for a home hobbiest as getting 100 amp service might be tough to do considering the average home only has 200 amps total. Some are greater but not in the homes a few years old.
