Here you go - http://www.ifi-inc.com/Products/Ribbon_Elements.php They usually fit in grooves in the fire brick furnace lining. The ribbons have pretty much replaced the old coiled wire elements.
So, all your coils have continuity, no shorts, same resistance reading, and same amp draw (which is also the correct rated amp draw). This seems to indicate that they're all "good" despite having babbit dripped on them, and it seems to indicate that they're getting the proper power. If it only goes up to 750 degrees, then maybe that's all it's capable of. I don't really see a way around that; if they're all drawing the proper amps then they're all dissipating the proper heat, according to ohms law - no need to look any further than that. I can't conceive a scenario where improper transformer connections or anything would trump it.I have 57.5 volts phase to phase, drawing 90 amp from room temperature, up to around 750 degrees in 15 minutes and that's as high as it goes.
