Is it possible to burn Hard metal with Copper electrodes?

02/03/2019 & 0183;& 32;You can get away with using plain Copper electrodes to machine Tungsten Carbide, but your electrode wear will be VERY high, so be prepared to re-machine or re-dress your electrodes several times. You should use the Copper Tungsten to Tungsten Carbide settings even though you would be using copper electrodes. -Brian. msrbl, roysol liked this post.
