Slide the heat shrink tube
over the solder joint and
then use a lighter flame to
shrink the tubing over the
joint.
Gently sweep the flame
back and forth over the
heat shrink tubing taking
care not to apply too much
heat.
Do not use open flame
around any combustible
materials and be careful
not to inadvertently melt
any of your plastic
components or braided
sleeve.
Use soldering iron to melt
solder on both wire ends so
that wire ends are
overlapping and solder
forms a complete bond
between the two wire ends.
