1. A portable device for stripping insulation from a wire for use with a source of direct current which comprises:
- a heating element;
means to chop direct current from said source into pulses of direct current;
means to vary the duration of said pulses; and
switching means for inductively coupling said direct current power to said heating element to heat said heating element in proportion to the duration of said pulses.

Abstract
A portable thermal wire stripper has a pair of heatable stripping blades which are electrically attached to an electrical power and control system. The electrical system converts a direct current output from a battery which is housed in the wire stripper into a variable alternating current power which is used for controlling the surface temperature of the heated blades.

13. A method for stripping insulation from wires, comprising the steps of:
-
selectively chopping direct current power to pulses of direct current; exciting an oscillator in response to the duration of said pulses to generate a flip-flop switching signal; coupling said direct current power to an electrical heating element to heat said heating element in response to said flip-flop switching signal; and positioning said heating element adjacent said insulation to heat said insulation for stripping said insulation from said wires.
