SA-200 all copper windings

I've heard the reface were all copper and the blackfaces had some aluminum but someone told me just recently he had welded I think with a 73 or 75 sa 200 and he thought it was the best he had welded with and he had a redface. People have told me that the all round ones I am assuming the cone on the generator that they were all copper but I have seen some welders that weren't perfectly round cones and they were redfaces so I am kinda lost as well on this subject. I have welded with a blackface onces and wheather redface or blackface it was a dam good welder. I really like how it had I guess you call it a soft arc to it not a gougeing arc like some of the millers I've welded with. I think the last year from what people have told me either 69 or like 73 maybe but don't hold me to it

I run a 65 redface and a 76 sa200 i think the 76 will root pass ,and fill and cap as good as my 65 i think it has alot to do with knowing the machine, i do know some old guys like the redface machines better and refuse to run the new machines, i am a die hard old grey horse fan!

Lincoln told me the last code number that was all copper was 7044. It was a black face. I have a 1970 model, black face that is all copper. Had a 1971 model that had the al/cu generator. They could not give a year. The generators that are completly round are all copper. They all seem to weld good, but there is a little difference.

I had a 63 red face, rolled the rack some, & added 300 amp brushes. It could go all day long. Real sorry I ever sold it. It goes back to the saying "they don't make'em like that anymore".

My 71' welds soooo smooth I could careless if the windings were old tomato cans. Knowing the machine is also a good point, I can guide the rod holder and it will weld by itself(not so for my Trailblazer301).
