Hi mark and group:
Here are some videos of doing a cadweld. Looks to me like you should
follow Steve's rule,
Do what the manufacturer says, and be safe. Anything else and you may be
pushing your luck.
if you have the right materials, the graphite molds and such, it looks
relatively straigntforward and safe...
The last video here shows a more complete ground system installaiton
tecnique by a company, SAE
They introduce a new material I had never heard of conducrete....
apparently conductive concrete, designed for the purpose...perhaps
interesting stuff...
