Desoldering Techniques - Continued
(5)
Position the stranded wire or shielding braid on the connection and place the hot soldering iron tip on top
of the stranded wire or shielding braid as shown in figure 4-30.
(6)
Hold shielding braid and iron tip against joint or connection until the desired amount of solder is
absorbed into shielding braid. Be careful not to over heat components. Remove the soldering iron tip
and the shielding braid simultaneously.
(7)
Allow connection to cool and then remove the flux residue with alcohol and a medium stiff bristle brush.

Stripping Insulated Wire.
a.
General. Wire must be stripped of insulation before it can be tinned or soldered. There are two methods of
removing insulation: thermal strippers for removing plastic insulation and mechanical strippers (precision cutting) for non-
plastic insulation.
WARNING
Good ventilation is required when using thermal strippers. Wire insulation gives off a toxic gas
when melted.
b.
Thermal Stripper (fig. 4-31). A thermal stripper uses a small loop of resistance wire, heated by electric
current to a high temperature.
