Five steps for maintaining and adjusting an electric soldering iron
1. For ordinary new electric soldering irons, necessary inspections must be carried out. Firstly, check whether the fixing screws are loose. Secondly, observe whether the power cord has cracks, exposed copper, or damage. Then, use a multimeter to measure whether there is a short circuit or open circuit at both ends of the plug. Finally, use a multimeter in X10K gear, with one foot touching the electric soldering iron head and the other foot touching the electric soldering iron plug at the same time. The pointer of the multimeter should not move. Only after the above steps can it be used
When using a new soldering iron head for the first time, the following methods must be used to improve its quality of use and extend its service life. If it is a regular soldering iron, the soldering iron head must be first inserted into the heating core hole and the fixing screws of the soldering iron head must be tightened Plug in the power and place the soldering iron on top of the rosin. As the temperature rises, the rosin melts until the tip of the soldering iron is covered with a layer of rosin solution. Then, place the rosin soldering wire on the tip of the soldering iron until the solder melts. Finally, evenly coat the chrome tip of the soldering iron with a layer of tin. The soldering iron can be put into normal use
During use, the working environment of the electric soldering iron head is very harsh, with high temperature and easy oxidation. The flux is corrosive and easy to corrode, and the hardness of the solder is high, which can easily cause wear and tear. The main problems with the soldering iron head are generally not eating tin (oxidation) and damage. For soldering iron heads made of metal copper, the oxide layer can be removed with a mixed file or the soldering iron head can be trimmed to the desired shape. Note that the soldering iron must not be cut off and cooled. After completion, the operation must be carried out according to item 1.3.2. For soldering iron heads made of alloy, if they oxidize, they can be repeatedly scrubbed on a wet sponge while adding rosin soldering wire until they are electrified. Wipe off the oxide layer and re coat the surface of the soldering iron head with a layer of solder. For alloy heads that have already cracked and damaged, they must be replaced
4 electric soldering iron is an electrical product that, like other electrical products, is afraid of water and moisture. Therefore, when using the PDF file to create a trial version of "pdfFactory Pro" www.fineprint.cn or when not in use, be careful not to store it in a damp or damp place. On the one hand, it can extend the service life of electric soldering iron, and on the other hand, it is to ensure safety, because water or moisture can cause a decrease in the insulation performance of electric soldering iron, leading to electric shock accidents
In the process of using an electric soldering iron, we can extend the service life of the soldering iron head and improve the welding quality by adjusting the soldering iron. The specific method is as follows: if the temperature is too high, the phenomenon is that it vaporizes immediately when it comes into contact with rosin, and the soldering tin turns golden purple (oxidized) immediately when it comes into contact with rosin. Then, the soldering iron head can be moved out of the heating core a bit. If the temperature is too low, it will vaporize slowly when it comes into contact with rosin, and the soldering wire cannot melt immediately when it comes into contact with the soldering wire. It is recommended to move a bit into the heating core of the soldering iron head until it is soldered, and it will melt immediately. In a short period of time (15-20 seconds), it will not oxidize. Note that the soldering iron of a 30W electric soldering iron is good. The length of the head left in the heating core should not be less than 1.5CM. The length of the soldering iron left in the heating core should not be less than 2.0CM, otherwise it will shorten the service life of the heating core
