Also, you said you'll try carbide drills as electrodes - i wonder where to
find information which electrode shows the least wear. Tungsten rods fo
TIG welding might be another option, if it is better than graphite (which
i don't think).
I think the industry uses graphite for sinkers and "soft" metals for other
machines like wirecutters, no?
