Cool and Inspect the Soldered Joint

What happens here

After applying the solder, turn off the torch and allow the soldered joint to cool down naturally. Do not use water or a wet rag to cool it down, as this can weaken the joint. Once the joint has cooled sufficiently (which should only take a moment for half-inch copper), carefully remove the pipe from the vise. Inspect the joint to ensure the solder has flowed completely around and formed a solid, leak-proof seal. If there are any black areas or excess flux residue, use the fitting brush to clean them off.

Goal: Ensure the soldered joint is secure and clean
