I have the dynasty 200 and yes its 20%@200amps but a lot of the big players probably Fronius included carry out this test in a 40 degrees C envoironment unlike most of the cheaper manufacturers that test @ 25 deg C,Miller dynasty Dx is 200@20%
So was my old magicwave. Tbh it's not a big drawback 2 mins solid at that current is enough.
Its funny how the fan on demand thing varies on different machines,The kemppi boasts similar stats but a lot of it is (I guess) fan on demand ain't the same as it once was. My old fronius would weld all day at 100 amps and you'd never hear a peep out of it where as the kemmpi fans kick in pretty much straight away, run on for ages. No wonder it's DC is good it's pretty much fan on constant.
They are nice to use once your head is round the panel. They weld very nicelyOld Kemppis arent like the new ones, they are style over substance these days in my opinion.
The 160 Triton i'm doing some work with now has a nice user friendly quiet fan like my Dynasty,My thoughts exactly. I could weld 3mm stainless forever on the magicwave and it would never cut the fan in never. It was also 20% like the dynasty and like the dynasty it was pushed and never missed a beat. Duty cycle isn't something I worry about after owning that machine.
The kemppi certainly has the bells and whistles and welds lovely but its not fan as needed like it states it's fan almost instantly. I think the kemppi is 40% at full whack which is great but not suprising as it spends most of its welding life making a row. I would assume the tetrix is similar? The old ewm triton220 acdc was also fan as needed but that like the fronius was rarely spinning and perhaps a lower duty cycle but I hammered it daily so it must of been good enough.
It will be that I would of thought. The heat sinks will be consistently cooled keeping the DC high. I'd sacrifice a bit of DC to avoid dust been bought in continuously on to the delicate boards.The 160 Triton i'm doing some work with now has a nice user friendly quiet fan like my Dynasty,
one thing thats rarely mentioned on here is how really damn noisy the fans are on R-tech tigs,
i think the reason behind that is that for most of the owners its their first and only tig ever so they assume its normal with nothing to compare it to,
saying that they do claim very high duty cycles for their machines mainly down to the powerful fan i'm guessing?
When does yours sort of kick in? I've had mine for a while now and I've never heard it yet. I'm beginning to wonder if it's because I don't do much or it's on the fritz!The 160 Triton i'm doing some work with now has a nice user friendly quiet fan
Crank it up to 140 amps and get some decent passes put down. It will cut in then. I'm sure it will work fine.When does yours sort of kick in? I've had mine for a while now and I've never heard it yet. I'm beginning to wonder if it's because I don't do much or it's on the fritz!
Another welder engineer told me that too.Old Kemppis arent like the new ones, they are style over substance these days in my opinion.
I doubt any inverter tig escapes far eastern parts on the circuit boards since most of the boards are made in Malaysia as we have no silicon Valley here. Siemens IGBTS etc are made in Germany so EWM might be German inside - Jim can answer that one.Thanks Jim. I did notice on their website that the Portamig and Oxford welders are British made but no such claim for the inverter tigs.
I used a newish Kemppi on Thursday for a few hours, it was nice to use.
Hopefully not annoying folk with all my questions. So what would be the best option if forking out a bit more cash? Say in the £1.5k range? I'd be hesitent to buy used unless I knew it came from a good home and hadn't been worked hard. I'm not a big tig user but want to use it again more (home workshop not a professional workshop) but I want one that welds nice and will last me years.

For 1500 you cam get a nicish machine as already discussed but you are along way from the Kemppi or Gys or EWM. I would go with the parweld personally or have you looked at one of jims SWP's?
I've always categorised them on arc stability particularly AC. I was looking for a new machine when I sold my magicwave (regrettably)* and my budget allowed me to try 2 units both used but both in warranty still. Miller dynasty Dx 200 and the Mls2300. My head was killing me trying to weigh them up because on AC arc stability they were so comparable I was looking at other features to win one over. The Miller IMO has the best panel layout baring none. It's just wonderful, self explanatory and all the scope under the sun. In the end it was made on one feature which I am glad about and that's current. The extra 30 amps on tap from a household supply clinched it for me and I went mls. But the panel on the mls is just not logical. All those lines colours, and dots make it appear like a map of the London Underground and the manual doesn't make it easier but through playing I made sense of it.
* I sold my fronius magicwave 2000 because of the one fact that the parts are becoming obsolete and I didn't want to have it go down and be worthless so I cashed in my cards. Had the parts still been available I'd of kept it without question. There was lots of advantages where the Mls and Dx were better but AC arc stability the mw2000 kicked ass over either on this. Oh well no point dwelling on it as its now gone and the mls is quality kit to use. I'm not one of these people "my welder is the best" I'm a realist and the mls has sooooo many points to it that could be waaaaaaay better. It's got some good ones too.
