The biggest downsides of Caddweld are:
  • damp molds where they have been left in a tool box or storage shed over the weekend
  • the process can not be used in rain or drizzle
  • the molds "wear out" after about 50 shots, then you have to be creative by using putty to seal against leakage or old pennies to add more copper to the mix (not listed since it changes the mix and has not been tested)
  • once in a while, if you are not careful, you will burn through instead making a good weld (operator error)

We used to use the Caddweld system for all of our grounding grids in our substations but have gone to the mechanical type because of the above downsides. [Linked Image]
