What kind of soldering flux did you use and how did you clean the excess off
before putting the cable in service? Use resin not acid flux. In my
opinion the heat was not the problem. the problem lies with the corrosive
properties of the soldering flux left behind in the process. In second
thought the heat could have caused some of the oils in the cable to burn
out. Re OILING the cable after cleaning off the excess flux should provide
good results. Remember when the solder wicks into the cable the flux is
forced further up the cable strands. so cleaning and re oiling is vital.

Ps just red ray's post and he is right on.
In my humble opinion, one should NEVER use any flux on the cables except
resin.
At the same time, with me a big no-no is never heat them with a torch, but a
medium heat soldering iron. I have soldered many cable ends, and other
sensitive
wires,etc. using this combination. Then when finished, brush the area with
alcohol. Have never seen any change in strength or evidence of corrosion.

On examination, there was noticeable discoloration from the point that was
soldered,
back about 1". The general consensus, of those that examined it, was that
the break was caused by the effect on the cable of the heat application.
(The
failure may have been accelerated by the humid conditions here in FL.) The
cable actually rusted through. Miffed that I didn't see the rust before it
broke. Some of the discoloration/rust protruded from the connector enough
to
be seen. Conceptually a good idea, with not so good results.
