Nice pics,
I just got time to have a good look at my machine and found out she is only single phase. The reason I thought it was three, at first glance, was that there was a 600V 3 phase power cord on the machine. My wiring is identical to yours Jack except one thing; the identity plate states that it is single phase 575 Volt 42 Amps. This is a little bumming because I would rather not use a transformer to step up the voltage but since my wiring is identical to yours I wonder if I could do the transformation to 230V even though it's not stated on the welder?
If comparing your photo with the manual diagram, what part do you move to get the higher (or lower) operating input voltage? The red square plate with 4 bolts on the left of L1 and L2 input? Is that the jumper plate? And where does it say the voltage?

Thanks Again
