I did my first Cadweld one shots a year ago. The hardest parts were mechanical
- had to touch up the ends of each ground rod with a file in spots where it was
mushroomed out from driving it, and getting the mold over the end of the rod (I
might have had a slightly-too small size) - the rubber gasket is pretty snug.
The rest was easy. Poured in the powder, grazed each with a propane torch at
arm's length (wrong tool, might blow away some of the powder but... hot enough,
running fairly low flame). It really only burns for a moment, though the
molten copper takes a few minutes to cool.
A brazing rod is certainly cheaper than a one shot, but also requires the right
(expensive) tools and a lot of skill
