do these welders have the same capabilities as the one i showed?
The Diversion 165 has the capability to weld Aluminum.
That is the major advantage, and it is more user friendly for a hobbyist welder.
The disadvantages are...
It's a dedicated tig machine, no smaw.
It requires 230v for power.
The torch looks to be integral to the machine. If that's the case I don't like that. Eventually your torch or torch power cable may kick the bucket.
I like to be able to run down to the welding supply and pick up replacement parts on the spot. I'm not sure if that's the case with the Diversion.
The last thing is, even though the Diversion can weld Aluminum it doesn't provide the operator with Squarewave which allows you to tailor the arc characteristics when welding Aluminum.
This may not be a big deal for a hobbyist, but for me it's almost a necessity.
I'm gonna make this short and sweet on the Dynasty 200 DX.
It rocks!
It's got more options than you would know what to do with. At least for a good while.
So, if you want the ability to weld Aluminum the Diversion is your choice.
If you don't care about Aluminum the Maxtar is the better choice.
If you want the benefits of both the Diversion and the Maxtar plus more!, than the Dynasty 200 DX is where it's at.
Again I will check with my co-worker on whether he wants to sell one of his Dynasty's
Another manufacturer no one mentions on this forum is Lincoln.

They are Miller's biggest competitor. Lincoln makes very good welders also.
So don't limit yourself to just one brand.
