It doesn't work - it just burns on as an impenetrable lacquer so you
have to scrape all the strands with a knife blade before you can carry
on and do the job properly with an active flux. If the solder takes on
any of the strands you can't easily scrape them so you then have to
cut the ruined strands off and start all over again!
soldering with an acid flux is OK *IF* you clean ALL the flux off
afterwards. (very iffy...)
Otherwise,the acid eventually eats thru the wire enough that vibration
breaks it.
BTW,some rosin fluxes are more active than others.
I wonder if you first cleaned the wires with Tarn-X,then soldered with
rosin flux,if that would be better?
