If you do find carbon arc electrodes, they will be copper clad. An easy
source for carbon rods is flashlight batteries (cells, actually.)

Not in the alkaline style. It's positive electrode is a ribbon.

You can still get carbon zinc cells (with the carbon rod):

Or at about any cheapo discount place. Cells marked "heavy duty" are
carbon-zinc rather than alkaline.
