The Fine Art
of Soldering
1. Cut tube end square, ream, burr and size.
When adjoining surfaces of copper and copper alloys meet under proper conditions of cleanliness and temperature,
solder will make a perfect adhesion. The strength of joint is equal to or even greater than the strength of tube alone.
Surface tension seals the joint. Capillary attraction draws solder into, around, and all about the joint. It’s easy to learn
to make a perfect solder joint when you use NIBCO
®
Fittings.
WITH 95-5 SOLDER AND INTERMEDIATELY CORROSIVE FLUX
6. Remove excess solder with a small brush or wiping cloth while
the solder is plastic.
2. Use sand cloth or steel wire brush to clean tube and cup to a
bright metal finish.
3. Apply solder flux to outside of tube and inside of cup
of fitting carefully so that surfaces to be joined are completely
covered. Use flux sparingly.
4. Apply flame to the fitting to heat tube and solder cup of fitting
until solder melts when placed at joint of tube and fitting.
5. Remove flame and feed solder into the joint at one or
two points until a ring of solder appears at the end of the fitting.
The correct amount of solder is approximately equal to 1

/2 the
diameter of the fitting…
