Electrical output for a generator powered forge

Question

I have a 7000 watt generator, and I am trying to use it to power a forge/foundry made of molybdenum wire and a casing that has a temperature resistance of 3000 degrees Fahrenheit. I was told I can't use more than 20amps from the 240 volt outlet or 40amps from the 120 volt outlet or it would damage the generator. Is there a way to use this setup for melting metals like steel? Or have I been trying in vain?

Answer 1

Molybdenum wire is great for high temperatures, but: Its resistance and power consumption must be precisely matched to your voltage and current supply.

If the wire gets too hot, or you try to draw too much current, it may burn out or the generator may overload. You may need to calculate the resistance of the molybdenum wire and ensure that the power = V² / R doesn't exceed generator capacity.
