One product in the plumber's toolbox that is used practically everyday and probably taken for granted is soldering flux. First introduced over 100 years ago, flux technology has seen rapid changes and improvements in the past several years. Let's examine the various types of flux currently on the market, and look at how to more effectively use this essential product.

Functions of Flux

A high quality flux will perform three major functions:

1. Clean the metal surfaces to ensure good solder flow.

2. Promote the flow of solder around the joint.

3. Protect the surface from recontamination.

The word flux literally means to flow or flowing, and describes one of the chief aims of a quality flux, to help the solder "flow" around the fitting as it is sweated to the pipe or tube. The flux is able to do this by governing three …
