i think this is the best diagram I've seen so far. Neither the halem nor the giberson books have a wiring diagram, which is surprising. this diagram is for a furnace not an annealer but the general principal i think is the same. a couple things about this diagram confuses me:
what is the plug for? i get that the 110v receptacle powers the temp controller and the 220v receptacle powers the elements but i don't get the whole plug thing on the bottom left. (or, the 220v plug powers the elemts and i don't get the whole 220 receptacle on the bottom right)
