There is a further hazard which nobody has mentioned yet: if the wires
are very fine (48swg or higher) and they are made of copper, they will
dissolve in ordinary solder. The way to overcome this is to use a
solder that is already saturated with copper, such as \"Savbit\".
It rarely causes a problem with normal work, but becomes significant in
the repair of moving coil meters and similar fine work.
I didn\'t measure the strands, but 8 of them twisted together made a
0.01\" diameter conductor. Pretty fine. Time will tell, but with any
luck I\'ll be dead before it\'s a problem.
I really hope I have misunderstood your reply: the copper dissolves
during soldering, not afterwards; so unless you are doing something
remarkably careless, you should still be alive at the end of it.
