To remove the enamel from litz wire
I use paint stripper called nitromorse.
Remove all the cotton/plastic
insulation from the cable end to be soldered to expose the multi strand
enameled wires. Brush the end of cable with a tooth brush to separate
the strands and flatten out.
Use the tooth brush to apply the
paint stripper to the splayed out cable strands, making sure it gets to
all the strands. Leave for about 10 minutes or more, then brush away
the disolved enamel. I carry out this process twice to ensure that all
enamel has been removed. The final job is to wash the exposed copper
cable end with turps etc using a cloth, then start soldering. I strip
back about 1 inch of the cable end.
I have used the above procedure a
number of times and it works well. Paint stripper and a tooth brush are
readily available. This method is also economical on solder, no need
for special tools like solder pots and bunsen burners.
Any good paint stripper would do. My
contents label says the stripper contains 5 - 20 percent
Methylene dichloride, it does not
say what the rest is.
Many years ago in the U.S., we could buy small bottles of "Strip-X"
made by GC Electronics.
