I have a piece of Litz wire that is about 100 feet long. The Litz wire is made of 10 tiny wires .004" diameter each wire. I folded it in half several times to get a piece of wire 32" long. The wire is made up of 32 pieces of Litz wire = 320 strans of .004 wire.
I have been trying to solder the ends but not having much luck. I tried to burn off the enamel coating on the wire with a small propane torch but it melts the wires. I tried lower heat it burns off the enamel coating but leaves the wires black and solder will not stick. I tried plumber flux to clean the wires but solder still will not stick.
I cut the wire end off and tried again with a new solder gun tip and solder. Enamel coating burns black, wires are black, solder will not stick.
