Ya done got my curiosity up .. here's what I found ... Mark, AA6DX
=========================================
Soldering Oxidized Copper Wires (Especially Stranded)
Go to the hardware store or welding store and buy a bottle
of All-State Duzall Flux (tm) for soft soldering.
Dip the connections in it or use a cotton swab (Q-tip) to
coat it and then heat it with the soldering iron while it is still
wet. It will be instantly clean and the solder will flow beautifully.
It works on stainless steel as well as other metals because
it is an ACID flux. So you must wash it off afterwards. Dip
the connection in clear water or use a squirt bottle to flush it
clean. It works exceptionally well with stranded wire. Just
make sure that you get plenty of solder on the connection so
that it flows throughout the strands & then wash thoroughly.
I have been using this techniques since the 1970s when I
was the engineer for the University of Colorado's Radio Astronomy
Observatory. Never had any problems if washed
thoroughly after the soldering. And it makes a tedious task
EASY!
Bottle claims it works on Stainless Steel, Chrome, Monel,
Copper, rass, Cast Iron, Galvanized, Gold, Sterling Silver, Silver,
Bronze, Coated Sheets, and other metals EXCEPT Aluminum,
Magnesium, and Die Cast. Contains Zinc Chloride!!!
