[1]General Caution (1)Use the right wire. Before use, check the magnet wire for type,size,etc,to prevent wrong use. due to improper storage, management or other causes. (2)Scratches made in transit Magnet wires have a thin layer of film which is easily damaged by sharp edges of metal qbjects. Utmost care should be taken during transportation or storage. (3)Storage Store magnet wires in a place that is free from dust containing metal particle, high levels of humidity, and direct sunlight. [2]Coil winding (1)Scratches made during work The magnet wire is coated with a film which can be scraped off by the edges of metal objects. During coil winding work, closely monitor the machine part which contacts the wire to ensure that undue force is not applied to the wire. (2)Tension of wire To avoid deterioration of wire quality, apply the least possible tension to it during coil winding. Refer to the "Standard of the Tension Safely Applied to the Wire in Coil Winding" to the right. (3)Varnishing Pre-heat the wire before varnishing and completely remove internal distortion of the insulating film : General magnet wire (Classes A and B) 100130×15-60min. Heat-resistant magnet wires (Class F or higher) 150×1560min. (4)Terminal preparation There are three methods of removing the film coating from magnet wire.    Electric burning; Mechanical removing with the machine; Chemical treatmet. Select the method that is best suited to the type of work. When removing mechanically, care should be taken not to scratch the conductor too deeply. When chemicals(remover)are used, they should be prevented from sticking to the part of wire not to be stripped. Residual chemicals should be wiped off after stripping, Otherwise, the residue can cause the conductor to break due to corrosion.
