Abstract
A process for treating a coil end is provided, by which upon automatic winding of the coil, an electric connection between a portion of a wire at the front or rear end of the coil and a terminal of a winding object by arc welding can be securely carried out. A stripping section strips an insulating coating off from the portions of the wire at the front and rear ends of the coil while the wire is wound around the winding object with the portions of the wire being bound to the terminal. Each portion of the wire, the insulating coating of which is stripped off, bound to the terminal is electrically connected to the terminal by arc welding.
