Arc furnace

Here is a neat little arc furnace that seems to work very well.

I have seen his videos before, could watch him for hours( and have)!
This cool arc furnace vid led me to the others where he makes a stick welder out of old microwaves!!!
too cool. Maybe I don't need to save up for the welder Ive been wanting so bad after all.

If you haven't seen the heat he produces with a fresnel lens, you should check that out, but I'm guessing you already have !
