The recipe for soldering success calls for two parts prep work and one part craftsmanship. If you do the critical preparation steps well -- joint cleaning and heating -- the solder itself will finish the job.
The basic soldering tool is a propane or MAPP-gas torch, which consists of a regulator and tip that you screw onto a small tank. To operate it, open the fuel valve and light the tip with a handheld striker or built-in igniter. Adjust the flame so the blue cone in the center is about 1-1/4 in. (3 cm) long. The longer the cone, the hotter the flame. The hottest point is at the tip of the cone, so hold the flame so the cone tip just touches the fitting. When the joint is heated properly, molten solder quickly flows into and surrounds the joint, hardening as it cools.
Be sure to drain water lines in the area being soldered and open a faucet at one end of the line so any pressure that builds up in the pipe during soldering can escape.
Cutting Copper Pipe
Copper is soft and relatively easy to cut with a tube cutter. In addition to a larger cutter, a small tight-area cutter will quickly pay for itself in time saved during remodeling work in confined areas.
1. Lightly pinch pipe between the cutting wheel and guide wheel. Rotate the cutter, scoring all the way around the pipe. When cutting resistance eases, tighten cutter knob a quarter turn and rotate again. Repeat until the pipe snaps off.
|2. Remove inside burr by inserting the reaming attachment squarely and twisting a full revolution.|
Cleaning Copper Pipe
Even if you're working with new pipe and fittings, all mating surfaces must be smooth and oil free. Clean outside surfaces with emery cloth and the insides of fittings with wire brushes sized to fit.1. Clean dirt and corrosion off the outside of a pipe end using emery cloth until the pipe shines evenly. Don't touch the cleaned surface with your bare hands. Skin oils can disrupt solder flow and negatively affect the joint.

BY AN AUTHOR WITH THE EXPERIENCE TO KNOW WHAT QUESTIONS YOU WOULD ASK!
Author R. Dodge Woodson, a master plumber with more than 20 years experience in the field tackles just about every plumbing topic imaginable, ranging from clogged drains to electric motors. He also includes useful data such as:
* Current Code Considerations
The author, whom has written a number of other titles on this same subject, has a wealth of knowledge about all facets of Plumbing. What is also notable as well as commendable is when reading his books, you get the feeling that he really likes this field. If Plumbing is your business, then it would be to your advantage to have this as well as some of Woodson's other titles in your collection. This book doesn't pretend to be any more than a vast, comprehensive reference tool--and in my opinion, succeeds. This is the book that you have in your truck if you are a plumber or on the shelf beside your desk if you are a designer. My only criticism (a minor one) is the lack of explanation of pumps and their sizing. Some charts and diagrams are offered but no explanation is given as a follow through. Overall though, I recommend the text as great reference resource every plumber should have.

This edition of Mathematics for Plumbers and Pipefitters continues to teach the essential math concepts that
have made the book the outstanding reference in its field. A collection
of modern fitting materials demonstrates the various math concepts, and the book emphasizes a problem-solving methodology that can be
applied to both current and future materials and job situations
in plumbing and pipefitting. Enhancements to the text include simplified
explanations, new drawings, a new unit on calculating partial volumes
in odd-shaped tanks, and a reworked unit on heat-loss calculations
that has been revised to keep pace with modern heat-loss methods.

|2. Clean inside of fittings with a wire brush sized to fit the pipe diameter. You can also wrap emery cloth around your finger to clean inside.|
Soldering a Joint
Flux is an acidic paste that etches the copper and helps carry the solder into the joint. When the temperature of the copper reaches the solder melting point, the solder liquifies and flows into the joint -- even if the joint is upside down.
1. Brush an even layer of flux over surfaces to be joined -- pipe ends and the inside of fittings. Push the joint together until pipe and fittings seat fully. You can prepare multiple joints at the same time.
2. Heat joint with a propane or MAPP-gas torch, moving its blue cone back and forth to heat fitting evenly. Hold lead-free solder against the joint on the flame's opposite side until it flows into joint and appears full on all sides.
Safety first -- Tame the FlameTo avoid fires, use a special heat-shield cloth when you solder near wood or other combustible materials. Also, shut off your torch whenever you set it down; the propane tank is top-heavy and can fall over and burn something if it's left on. Finally, keep a fire extinguisher nearby.
