I still vote for the Dynasty 200 DX.
If you need to weld thicker stuff the power it has to produce a puddle at 200 amps and 250 hz is no less than amazing to me.
If you ever had a project that you needed to weld thicker material than it can handle then you can go to a helium mix and it will weld much hotter.
Same with the TA machine or any of those mentioned as well.
I buy Miller because that is what I can get service and parts for. Plus I think they are all around the worlds best welders And they are made in the good ole USA
