Cord electric soldering iron is typically not heat-resistant insulation. Therefore at its hit on a hot tip, perhaps a quick melt insulation and short circuit of wires. To avoid this, it is necessary to wear a cord round the required number of ceramic insulators that are used in the irons and frying cabinets. Plug contemporary electric soldering iron in most cases, non-separable, so it should be removed and strung on the cord insulators, mounted on the end of wires modular plug.
