Hi there i just bought a plasma cutter that operates at various different input voltages. These are all selectable by using different jumper placements. Input Input Current Recommended Voltage Phase @ 6 kw Output Slow-Blow Fuse Size 208 VAC 1 50 amps 70 amp 240 VAC 1 43 amps 60 amp 480 VAC 1 25 amps 35 amp There is another model that operates at 200, 230, and 400VAC. My question is can i hook my plasma cutter up to the 230vac on one of these settings? Or do I need something like a Buck transformer. Thanks for any help in advance!
