No need to wait for it to harden and you can solder the next joint right away since the molten solder will harden as the heat subsides. And since the hottest point of the flame is at the tip, ensure that it just touches the fitting. The solder, on the other hand should be on the coolest point, the opposite of the flame because it easily melts.
Wait for about 30 to 45 seconds to put pressure on the joint. As for sweating the brass valve on the copper pipe, remember that you will need to apply heat longer.
Contact Us Step-by-Step Process: First, you need to gather the tools and supplies you will use for the process. Step 2: Prepare and assemble soldering tools.
Step 3: Cut the copper tubing. Step 4: Clean off the burrs. Step 5: Clean the tubing. Step 6: Clean using fitting brush. Step 7: Apply paste flux. Step 8: Start to solder.

If you cannot tip-drain your pipe, use a dry, clean cloth or some paper towel to absorb all liquid near where you will be sweating the pipe.
Make your pipe shine. This is necessary to promote the best possible joining between your component parts. Take your wire brush, and clean the pipe until it shines brightly. Give the joint ends the same treatment, until all the ends you will be sweating have a bright sheen. After cleaning the pipe, wipe away any grit with a clean rag.
Cleaning the pipe removes oxidation buildup from the metal, which can cause a weak bond. If you are connecting to a valve or other fixture, be sure it is open so you don't melt or warp any internal seals. Part 2. Protect yourself with gloves. Although flux for potable fixtures is specifically intended to be non-toxic to your drinking water, flux that has yet to be heat treated can be harmful if it gets in your eyes or any open cuts.
You should wear gloves when applying flux to your pipe. Prevent trickles with a pipe plug. You shouldn't attempt to solder pipes that have residual water, as even a small amount of water can make your efforts futile. If you notice a trickle of water in your line, push a pipe plug into the line to stop the flow of water.
In the event that you don't have a plug on hand, an old trick used a wad of soft, white bread in the place of a plug to briefly halt the water.
This technique does work, but has a minute chance of clogging aerators or valves when the line is turned on and the bread flushed. Apply flux to the joint you will sweat. Copper pipe will not bond with the solder you will later apply to adhere your pipes together unless it is chemically treated with flux. Remember not to apply flux with your bare hands, as contact with your eyes, mouth, or open cuts could expose you to unsafe chemicals.
Only a small amount of flux needs to be applied. Wipe away excess flux with a clean cloth. Heat your fitting. You'll need to use your torch for this purpose. Hold your torch about 2 inches 5. As the flux melts, it will first get shiny, then the copper should darken, and finally the flux should begin to sizzle and smoke slightly.
This indicates that the pipe is ready for soldering. Be careful to avoid burning your forearm, or any other part of your body, on the heated pipe, which will be hot to the touch. Focused or extreme heat is not necessary to melt your flux; the paste will melt at a relatively low temperature. Assemble the connecting pieces. Again, taking care not to burn yourself on a heated part, you should insert the tube end into the fitting cup firmly until you feel the tube come to rest against the base of the cup.
Twist your pipe slightly to spread the flux evenly inside the joint. Reheat the entire fitting. Now that your pieces are joined, you'll want to heat these again to prepare for the application of solder. Pass your torch evenly over the copper of the fitting. Unevenly heated copper could cause uneven melting of your solder and compromise your watertight seal. Part 3.
Test your fitting to verify proper soldering temperature. You do not want to overheat your pipe and you should avoid applying your torch directly to your flux or solder as well. You can test to see if your pipe is ready for the solder by holding the solder to the pipe.
For safety reasons, it is always a good idea to use a striker, not an open flame, to light a torch. Using copper pipe cutters is an easy way to cut the necessary pipe lengths. The cutters leave a nice straight edge and they help to minimize burrs on the cut edge. Making sure that the pipe and fittings are clean is probably one of the most important things to do before you begin soldering copper pipe. A good sandpaper cloth is necessary to clean the outside of the copper pipe.
To clean the inside of the copper fittings, use a fitting brush. The wire bristles can prime the inside of the fitting to make good contact with the pipe. A fire cloth, a spray bottle with water, and a fire extinguisher are very important to have on hand when soldering copper pipe so that nothing catches on fire.
There are kits you can buy that have most of the basic soldering tools in them, which will often save you money. Consider that option unless you are looking at buying specific items such as a better-than-average torch, more solder, or a specific flux. Actively scan device characteristics for identification. Use precise geolocation data. The two methods utilize different materials, tools, and techniques.
Plumbing soldering requires acid-based flux, which the plumber applies before soldering. Electrical soldering typically utilizes rosin-core solder, and it already has flux inside its core. Also, soldering plumbing pipes requires a torch, while electrical soldering requires a soldering iron.
