while working with CADWELD ® exothermic welding
products.

Gather the proper materials and equipment for
the type of connection you are making. The typical
CADWELD system requires a graphite mold, handle
clamp, welding material, natural bristle brush for
mold cleaning, wire brush for cleaning/preparing
conductors, flint igniter, and propane torch.
NOTE: Additional materials may be required
for your specific application. Refer to your
mold instructions. Advise nearby personnel of
welding operations in the area prior to ignition.

Check to ensure the graphite mold is not worn or
broken, which could cause leakage of molten weld
metal during the reaction.
