When winding or repair transformer coils is that the end of the wire winding falls between the winding and the cheek of the coil so that it does not get the tweezers, although it is still visible. To draw, use a sewing needle. The eye of a needle (appropriate to the wire diameter) carefully put on the end of the wire, the needle is rotated around its axis by half a turn and pulling the needle, slowly pull the end of the wire.
Similarly we proceed in the repair of a ragged or burned-out frame wire of electrical device (egip), to prevent damage to the wire winding frame, insulating them. Released ends trimmed, spliced, the frame is electrically cold-call, the place of lay probailout and insulate a drop of Tapolca, by holding it at the tip of the scalpel. As a rule, the loss of one coil on the frame are renewable: if the device 100 µa or less. For tougher instruments it is necessary to increase the ends of wire of the same diameter.
