Hi Mark, In these systems the elements are in series in multiples that add up to 60 volts. I have four elements that each take 15 volts to push 170 amps at temp. Your big considerations are the high amperage loading and very low resistance of moly. If you run moly at less than rated amperage it doesnt put out the wattage you want, just like any other heating element. The commonly available four to one stepdown transformers can give you the low voltage that you need along with bumping the current up where you want it. Or you can devote a whole 200 amp panel and use the current limit function on the scr to hold it all back. 240v x 200a gives 48000watts, I know several folks melting 300lb on half of that. Steve.
