Rendering Line-frequency furnaces draw very high secondary currents and short-circuit the transformer every melt. Interleaved winding construction keeps impedance low and current shared evenly, while the clamping system and cooling are sized for the mechanical forces and thermal cycling that come with repeated melt cycles.
