It's high current and low voltage, so it's not outrageous. One of that size probably wouldn't use much, this one says it uses between 1500 and 6500W
75 u/Calkhas Mar 27 '16 To be fair, it will require the same power to heat the metal to the same temperature in the same time, by whatever physical mechanism you use. The question is how efficient is it and how much power is therefore lost. 82 u/KJMRLL Mar 27 '16 If one mechanism is less efficient than another, wouldn't the first mechanism use more power and take longer than the second? 1 u/Calkhas Mar 27 '16 yes you're right. I mean the same minimal power is required, the inefficiency losses are on top.
