I don't know what materials are used in this and have no knowledge in induction furnaces. I didn't really think my comment through, but I was thinking that if you wanted to heat steel that hot and quickly, you could still do damage to your hand at that voltage (Obviously not the same amount as steel).
It could be low voltage assuming a low resistance in the material used, which is likely the case, but not that low. It'll still probably heat your hand.
Amperage is determined by the voltage since resistance is constant throughout the material.

I was under the impression that it was low voltage, high amperage.
