When I started shopping I was looking for the most features for my money, and in all honesty, if I could have got all the features the 256 has in a 200 amp machine I would have bought it.
Enough rambling. A old employer is looking for a tig machine to weld aluminum for his kit plane project. He is dead set on a diversion 165. He is a lil upset that he has to pay extra for a pedal. So I invited him over to try my 256 out, and I'm thinking the PT200 is what he should look at? or the PT225?
So maybe a comparison chart would be in order?
