Stripping Insulated Wire - Continued
Insert the insulated wire into the thermal stripper and melt a ring around the insulation at the desired length to be stripped.
Pull off the insulation between the melted ring and the end of the wire either with the thermal stripper or a pair of long-nose
Figure 4-31. Thermal Stripper
The use of mechanical wire strippers may nick wire or break wire strands if not used properly.
Nicked wire or broken strands of wire cause the wire to be mechanically weakened as well as
reducing its current-carrying capacity.
The use of adjustable wire strippers is not permitted. Adjustable wire strippers can become
maladjusted causing broken strands or nicks in the wire.
Mechanical Stripper (fig. 4-32). A mechanical stripper uses a split cutting blade with notches. When closed,
the split cutting blade becomes cutting holes completely encircling the wire to be stripped.
