Switching power and control transistors everywhere makes an old Iron TIG
look like a stick welder - which most do. This tig - didn't look it up -
might not be a stick welder as well.

Plasma - portable machines are like this - light weight and run off a
gas bottle of N2 not air. Nice for off site. Nice to keep dry and
pure. Better torch beam and longer lasting.

About half way down the following page one of the guys took pictures
with the covers off. Kind of interesting. Looks a lot more like the
inside of a high power stereo rather than a welder...

I'd still like to see inside the Lincoln for myself...

I need some of you that aren't using eternal.september to quote this.
Otherwise I don't think Eric will see it...

I've got an older Lincoln Square Wave 175 and it's insides appear more neatly made than that AHP to me also. I recently had to send the circuit board out for repair. Had more than enough test equip. and background to fix the thing, but good luck finding a schematic for one anywhere. If anyone knows of a source of Lincoln circuit board schematics, I'd sure appreciate them posting it here.
