a source of heat. The torch is adjusted to what type of flame?
h. The use of a proper flux, the close union of the parts to be soldered,
and the application of adequate heat to make the solder flow freely are
important to accomplishing a proper radiator soldering job. What is a good
soldering job dependent upon?
