In some cases, we redress the roughing electrode to use as an additional finishing electrode. The savings in graphite costs alone make this a plus, he says. For larger electrodes, this may represent several thousands of dollars. It works because the used electrode can be measured for wear and a new program to compensate for those values can

Zinccarbon battery Wikipedia

A zinccarbon battery is a dry cell primary battery that delivers about 1.5 volts of direct current from the electrochemical reaction between zinc and manganese dioxide.A carbon rod collects the current from the manganese dioxide electrode, giving the name to the cell. A dry cell is usually made from zinc which serves as the anode with a negative electrical polarity, while the inert carbon

Graphene Wikipedia

Graphene is an allotrope (form) of carbon consisting of a single layer of carbon atoms arranged in a hexagonal lattice. It is a semimetal with small overlap between the valence and the conduction bands (zero bandgap material). It is the basic structural element of many other allotropes of carbon, such as graphite, charcoal, carbon nanotubes and fullerenes.

Mine use graphite. It's got great heat resistance, and decent electrical conductivity. I think my system actually works better because the sharp tips of the graphite electrodes (remember kids, conductivity is proportional to area of the cross-section) have higher resistance, so they heat up and help melt the copper.
