Abstract

PURPOSE:To improve productivity without inflicting mechanical effects on a coil by carbonizing and stripping off an insulation coat of a coil, jutting out a stripped part and fixing a segment through ultrasonic welding. CONSTITUTION:An arc is applied to a coil 2 with the help of TIG arc generating device 4 so that an insulation coat 2b may be carbonized and stripped off. A compressed inert gas 6 such as argon, etc. is pressured fed into a cylindrical case 5. At the same time, a minus-side tungsten electrode 7 is attached inside the cylindrical case 5 and a plus-side copper electrode is arranged opposed to the former electrode which is interposed together with the coil 2 between the pulse-side electrodes. Also a cooling channel 8a is formed on the internal periphery. A forced cooling is carried out by a cooling water 9 which circulates through the said channel. Under this constitution, the insulation coat 2b is heated by an arc and is carbonized to be detached from a core wire 2a with the assistance of a jet stream of argon gas 6. Consequently, a series of works can be performed smoothly resulting in an increased productivity.
