First off i'm no electrition. I want to build a casting pot with a master pot to melt up to 100lbs of lead at one time. Next I want to have a slave pot which is fed by the master pot. I want to controll the setup with two PID temperature controllers and I want to mount them so that the slave pot top is flush with the top of my bench. The idea is that I can pre melt lead in sufficient quantity that I do not have to wait for my lead to get upo to temperature. I am making a business of casting large bullets with a ladel (from car movers) and am fairly fast with a usual rate of 500/hr 45 cal, 260 grn bullets and can pour 850 40 cal bullets an hour. I need to put a bottom pour type valve in the master pot so as to fill the slave pot. I could use two lee pots and let one recover while using the other. I buy my lead in 63lb pigs and could save time by being able to feed 30 lbs of the pig at a time.
I am thinking of a 230v/2500w band heater element for the master pot and a 500w/230v band heater on the 5"x3" slave pot. I have two PID conrtrollers. One auburn instruments, and one from a cast boolit poster in Alaska , which is awsum. If I use a 440 band and hook it to 230 it will only produce 1/2 the rated wattage, correct?
