How to Operate a Soldering Torch
Plumbers and do-it-yourself enthusiasts use soldering torches mainly for copper water pipes, for a strong and long-lasting connection. Operating a soldering torch is relatively easy. But most beginners make the mistake of trying to melt the solder into the connection rather than simply heating the pipe with the torch until the solder "sweats" into the connection. With a little practice, you can soon be making professional-looking connections every time. Does this Spark an idea?
Instructions

-
1
Clean and assemble the pipes you want to connect. Apply a thin coat of soldering paste.
-
2
Screw the head onto the tank of your soldering torch.
-
-
3
Point the torch away from anything flammable. Open the valve about 1/4 turn, until you hear the gas escaping.
-
4
Light the torch with the igniter, cigarette lighter or matches.
-
5
Adjust the valve for a flame about 1 1/2 inches long.
-
6
Point the tip of the flame directly at the joint to be soldered. Hold it there for about 10 seconds.
-
7
Touch the solder to the top or the joint. If the pipe is hot enough, the solder will "sweat" into the connection. If not, pull the solder away and continue heating the pipe. When it is hot enough, the solder will melt immediately and "sweat" into the joint.

8
Pull the flame and solder away as soon as the solder starts to drip out of the bottom of the connection. Quickly wipe it clean with the rag.

9
Turn the valve off and wait for the torch to cool. Unscrew the head from the tank and store it until the next use.

Tips & Warnings
Soldering torch kits are available at most home supply stores. Sales representatives usually will help explain how to operate them.
Be careful not to burn anything around the pipes you are soldering.
Just in case, keep a fire extinguisher or bucket of water near in case you start a fire.
