The Hakko B5038 Soldering Tip Enclosure with Nut is an accessory for use with the FX-8806 Soldering Iron Handpiece to be used with the T32 Series Soldering Tips. It is easy to remove a nut, an enclosure pipe, and a tip from a brand-new soldering iron. However, oxide and carbide accumulate among the metal parts through repeated use, and the parts stick to each other. As a result, disassembling may be impossible. This phenomenon is called "seizing". If disassembly becomes impossible, replacing the seized parts with new ones is necessary. The more severe seizing, oxidation, and carbonization of the parts will get, the worse the heat transfer to the tip will be. As a result, soldering quality will be poor. Also, it can be a cause of the increase of the tip to ground resistance and leak voltage. Therefore, the regular preventive maintenance on the parts is recommended.
