Well,  It draws 30A at 240V.  So Do the math and you see that its drawing
7.2kW max (I'm not sure if this is constant).

Yes those two links are incorrect,  Thanks for pointing that out.

I believe those diodes aren't rectification,  as the manual states "The
output of this device is high voltage/high frequency...)  And the +
electrode goes right to the output transformer.
