The large machines should have a selenium rectifier inside, if not very large diodes, and those rheostats, volt and amp meters and large those wire wound resistors should ebay.

Single phase welder has 4 diodes while your three phase will have 6 half of those will be positive case the nut side while the rest will be negative on the securing nut, bear that in mind when your offering them for sale.

Any large capacitor or toroid coils the Tesla and high voltage geeks go nuts over this stuff. http://en.wikipedia.org/wiki/Tesla_coil

I noticed a couple of those wire wound resistors while doing the disassembly of one of the Linde's today. I'm not an ebay'er right now, have to get working on that. Here is a pic of most of the insides of the unit.

Pile 1 includes the fan and power cable, it weighs 45 pounds.
Transformer 2 weighs 60 lbs.
3 weighs 10.
variable auto transformer 4 weighs 25.
5 weighs 75.
6 weighs 40.

So, 210 pounds in Transformers plus the other pile of goodies and the steel case. 210 x $.30 = $63.00 and all I can find from the local scrap yards posted online is $.27 a pound for transformers or electric motors. It will be interesting to see how these things weigh out when disassembled. There is a lot of steel in them and I'm not sure if it'll even be profitable to strip the copper off of them.
