The CADWELD

ONE SHOT Process

Fig. 4

The conductors should be clean and dry before the

connection is made. Use a propane torch to dry wire

conductors and remove remaining cleaning residue,

solvent, or water before making the CADWELD

ONE SHOT connection.

Next, use a wire brush to further prepare the surface

of the conductors and ground rod (CADWELD

T-313

or T-314 brush).

Scrape the outer surface to remove dirt and oxidation.

You will notice a slight color change.

Each CADWELD ONE SHOT contains a rubber

grommet at the bottom of the mold.

Gently turn the CADWELD ONE SHOT onto the

ground rod until the ground rod reaches the stopper

and cannot go any further.
