What to use to solder a shut off valve
Wet on the surface is no problem, it will evaporate with the torch. If there is water in the pipe, it will not solder because the water keeps the copper from getting hot enough. As long as the water is below the point of solder, it will work. Open the nearest valve or have some way for the steam to get out of the pipe.
For copper pipe, lead-free solder is recommended to ensure safe and effective connections.
To install a copper shut off valve in a plumbing system, first turn off the water supply. Cut the copper pipe where you want to install the valve using a pipe cutter. Clean the ends of the pipe and the valve with sandpaper. Apply flux to the pipe and valve, then solder them together using a torch. Allow the joint to cool, then turn the water supply back on to test for leaks.
To fix a copper pipe, you can use a pipe cutter to remove the damaged section, clean the ends of the pipe, and then solder a new piece of copper pipe in place using a propane torch and solder. Be sure to follow proper safety precautions and techniques when working with a torch.

To properly solder a copper pipe, first clean the pipe and fitting with emery cloth. Apply flux to both the pipe and fitting, then heat the joint with a propane torch. Once the joint is hot enough, touch the solder to the joint and let it flow around the connection. Allow the joint to cool and wipe away any excess solder.
tig or mig depending on the wall thicknessCopper to copper is either soft soldered, or silver solderedSilver solder is a bad term as "solder" normally means lead content according to the AWS
Use a lead-free silver solder. It is the only thing that can handle the pressure and bond with the copper pipe.
To repair a copper pipe, you can use a pipe cutter to remove the damaged section, clean the ends of the pipe, and then solder a new piece of copper pipe in place using a propane torch and solder. Make sure to follow proper safety precautions and techniques when soldering to ensure a secure and leak-free repair.
It is probably referring to the type of fitting. A fitting that is soldered to a copper pipe. It is called sweating when you use solder and a torch to connect copper pipe together or attach fittings to copper pipe.
