If you are using a flint igniter, keep it away from your face. I have seen a hot steel disk fly out of a mold that was not closed properly. Always double-check the clamp.
Compatibility with Other Grounding Materials
Copper clad steel welds beautifully to pure copper, galvanized karfe, and stainless steel—provided you use the correct filler material. For copper-to-steel joints, use a copper-based filler. For stainless steel, a nickel-based filler is required. Never mix fillers. The exothermic welding process creates a bond that is electrically continuous and free of galvanic cells. This is a huge advantage over clamps, which create a bimetallic corrosion site.
Standards You Must Follow
Your grounding system must comply with IEEE 80 (substation grounding), ASTM B227 (CCS rod specifications), and UL 467 (grounding da bonding kayan aiki).
