I've used a mapp torch to light one shots. My tower has 27 cad welds.
I also have a K0XG base and have a stranded 2/0 welding cable to connect
from the tower to the grounding system, the rest of which is #2 solid. It
is cadwelded with one-shot and it worked like a champ.
I bought all of mine from tessco.
