ABSTRACT:
A wirestripper for thermal stripping a length of insulated wire includes a "V"-shaped flat metal strip of nickel chrome alloy 0.2 mm thick and having first and second arms 1 mm wide and 3.2 cm long extending from a vertex. The "V"-shaped strip is supported between a support post at the vertex and a respective electrode post at the end of each of the arms, with the electrode posts and support post being parallel and biased apart to tension the "V"-shaped strip. The electrode posts are spaced apart a sufficient distance to permit the length of wire to be stripped to be passed laterally therebetween and between the first and second arms into the vertex for stripping. The serial resistance of the "V"-shaped strip between the electrode posts sufficient for energization of the strip by a 1.2 volt battery connected to the electrode posts.
