5 maintenance adjustments for your soldering iron
1. After getting an ordinary new soldering iron, necessary inspections must be carried out. First, check whether the fixing screws are loose, and secondly, observe whether the power cord has cracks, exposed copper, or damage, and then use a multimeter to measure both ends of the plug. Whether there is a short circuit or open circuit, finally set the multimeter to X10K, touch the soldering iron tip with one foot, and touch the soldering iron plug with one foot at the same time. The multimeter pointer is not allowed to move. It can be used after the above steps.
2. When using a new soldering iron tip for the first time, you must use the following methods to improve its quality and extend its service life. If it is an ordinary soldering iron, you must first install the soldering iron tip into the heating core hole and tighten the soldering iron tip to fix it. Screw. Plug in the power, press the soldering iron on the rosin, and as the temperature rises until the rosin melts, the soldering iron head is covered with a layer of rosin solution. Then press the rosin solder wire on the soldering iron head until the solder melts. , finally, after the solder is evenly coated with a layer of tin on the head of the chrome head, the soldering iron can be put into normal use.
3. During use, the working environment of the soldering iron head is very harsh, the temperature is very high, and it is easy to oxidize. The flux is corrosive and easy to corrode. The welding material has high hardness and is easy to wear. Problems with the soldering iron head are generally caused by not eating. Tin (oxidation) and damage. For soldering iron tips made of metal copper, you can use assorted files to remove the oxide layer or trim the soldering iron tip to the required shape. Note that the soldering iron must be cooled without cutting off the power before proceeding. After that, you must follow the operation of 1.3.2. For the soldering iron head made of alloy, if it is oxidized, you can repeatedly scrub it on a wet sponge while powering on and add rosin solder wire until the oxide layer is erased, and the surface of the soldering iron head can be re-enameled. Apply a layer of solder. For cracked and damaged alloy heads, the only option is to replace them.
4 The soldering iron is an electrical product, and like other electrical products, it is afraid of water and moisture. Therefore, when using or leaving PDF files without using "pdfFactory Pro" trial version creation www.fineprint.cn, be careful not to get wet. Keeping it in a place with water or moisture can not only extend the service life of the soldering iron, but also ensure safety, because water or moisture will cause the insulation performance of the soldering iron to decrease, causing electric shock accidents.
5. During the use of the soldering iron, we can extend the service life of the soldering iron tip and improve the welding quality of the soldering iron by adjusting the soldering iron. The specific method is as follows: If the temperature is too high, the rosin will vaporize as soon as it touches it. If the solder turns golden purple (oxidized) immediately, you can move the soldering iron tip out of the heating core. If the temperature is too low and the rosin vaporizes slowly when encountering it, and the solder wire cannot be melted immediately, you can move the soldering iron tip into the heating core. Move a little in until the solder is added and it melts immediately. It will not oxidize in a short time (15~20 seconds). Note that the length of the tip of the 30W electric soldering iron should not be less than 1.5CM in the heating core. The length of the 50W electric soldering iron should not be less than 1.5CM. The length of the soldering iron left in the heating core cannot be less than 2.0CM, otherwise the service life of the heating core will be shortened.
