What is it? Exothermic welding is a welding process for joining two electrical
conductors. it uses a superheated copper alloy to permanently join to
conductors ...
. . .includes various one-shots. Study carefully to find the exact right
one, including the diameter of your ground rod. That, you can get a lot of
places. The real value is the little "igniter gun" farther down the page.
Scroll down until you find their igniter product that looks like a little
gun. We had a lot of cadwelding to do and accidentally experimented. I
tried a couple of other methods and frankly, as we discovered, they were
dangerous. Some use ordinary sparklers to ignite these things and we had
some singed knuckles when we tried that. Likewise, ordinary
flint-and-steel of various sorts. Never again. Could have easily had 3rd
degree burns. This little "gun" version of it gets your hands just far
enough away to be reasonably safe. Try and ignite it at an angle for
further safety -- the stuff mostly goes straight up. But, you need a gap
between you and the actual ignition.

I will be connecting no. 6 copper wire to 8 foot ground rods and plan to

that I will cad weld the connections. I am a newbie at Cad Welding any
advice, and where is the best place to get cad welding supplies ?
