Today, I was able to install a couple of exothermic welds on a grounding grid for a new building.
We have one of those graphite molds that fits over the top of the ground rod, and allows a #2 wire to pass-thru. The end weld forms a "T" ....
I was having problems getting the starter powder to ignite (using a torch). I didn't have a flint striker handy. We finally got it going by "stirring" the starter powder with a scrap piece of wire while the torch flame was shooting into the side slot.
I figure that I could use some July 4 sparklers the next time for better results....
