Electric Arc Furnace?
I've done a lot of thinking on it, and I decided that I'm going to make an Electric arc furnace for a multitude of reasons.
I plan to use an arc welder as the power supply, with two carbon rods as the electrodes, creating an arc just above the crucible to melt the metal. I was wondering if anyone has done anything like this before?
I plan to have the furnace body made out of firebrick and refractory cement. Would this pose any problems?
Also, how much strain does this put on a welder? Will it need to be shut off after a while due to overheating, or can it sustain it's own?
Finally, How much power does a typical arc welder use? (in terms of watts)
