Gather the proper materials and equipment for the type
of connection you are making. The CADWELD ® ONE
SHOT system requires a CADWELD ONE SHOT ceramic
mold, welding material, 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 ceramic mold is not broken,
which could cause leakage of molten weld metal
during the reaction.
Inspect the CADWELD ONE SHOT box label to ensure
that it corresponds to the application, indicated by the:
1. CADWELD ONE SHOT part number
2. conductor size
3. welding material required
4. other materials required
The mold must be correct for the conductor size and
application. DO NOT MODIFY MOLDS.
