How to use and maintain an electronic circuit soldering tool soldering iron?
Use and maintenance of soldering iron, need to pay attention to the following issues:
1、Before using the soldering iron, it must be carefully inspected, and if it is damaged, it should not be used.
2, should be through the single-phase three-wire socket to obtain power, and the grounding wire should be reliably grounded or connected to zero.
3, the power cord should not be connected too long, should not be curled, and should not use low-strength plastic wire as the power cord.
4, the first time you use a soldering iron, the first soldering iron head immersed in a layer of tin. The method of dipping tin: after heating the soldering iron head, wipe off the oxidized layer on it, dip it in rosin, and then dip it in the molten tin.
5, the soldering iron use for a period of time, should be removed from the iron head, remove and heat transfer cylinder dissatisfaction parts of the oxidized layer, and then loaded, in order to prevent after the iron head can not be removed.
6, in the process of using the soldering iron, can not be arbitrary knocking iron head. Soldering iron should be held lightly to avoid damage to the internal heating element.
7, the iron head should be kept clean. In the use of the soldering iron head often in the asbestos felt friction children, in order to remove the oxidized layer. After a certain period of time, the surface of the soldering iron head may not appear on the tin (" burnt") phenomenon, at this time the first scraper to scrape off the solder, and then file to remove the surface of the black and gray oxidized layer, and then re-impregnated with tin.
8, in the use of a certain period of time, the surface of the soldering iron head will appear corrosion pits, lose the original shape, which will affect the normal welding. At this time you can use a file to shape it, trimmed to meet the requirements of the shape after dipping tin.
9, the soldering process temporarily not use the soldering iron, should be placed on a special iron on the bracket, to avoid damage to the wire or other objects; soldering iron should be placed away from flammable objects to prevent causing electrical fires.
10, at the end of welding, to immediately unplug; soldering iron cooling should be properly stored for reuse.
