I am getting ready to install some ground rods for the tower.
The PolyPhaser literature and, I believe, the NFPA literature talks
about welding the ground wire to the rods with "exothermic welding."
It sounds a little like witchcraft starting with some aluminum oxide
powder and copper powder and an ignition powder with a form to put it
all in.
Anybody acquainted with exothermic welding?
