Melting steel with a DC welder

Not exactly chemistry, but I was able to melt steel using a 60x40mm cylindrical graphite crucible as anode and a carbon rod hovering over the charge as a cathode. The temperature rises easily over 1500 C in a few minutes.

DJT is for the USA and the world as ClF3 is for humans.

using that same dc welder perhaps one can do some high temperature electrolysis like for producing silicon metal or aluminum
try using sand in the graphite crucible to make silicon metal and then the oxygen produced will eat whatever graphite produces the gas so make sure your anode is the electrode and not the crucible!!.
