Introduction to maintenance and adjustment of 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 there are cracks, exposed copper, or damage in the power cord. Then, use a multimeter to measure whether there is a short circuit or open circuit at both ends of the plug. Finally, use the multimeter in X10K gear, with one foot touching the soldering iron head and the other foot touching the soldering iron plug at the same time. The pointer of the multimeter is not allowed to move. Only after the above steps can it be used
When using a new electric 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 electric soldering iron, the soldering iron head must be first installed into the heating core hole and the fixing screws of the soldering iron head must be tightened Plug in the power, press the soldering iron onto the rosin, and as the temperature increases until the rosin melts, cover the soldering iron head with a layer of rosin solution. Then, press the rosin soldering wire onto the soldering iron head until the soldering tin melts, and finally evenly coat the chrome head 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 soldering flux is corrosive, 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. Attention must be paid to not cutting off the power to cool the electric soldering iron, After completion, the operation in item 1.3.2 must be followed. For the soldering iron head made of alloy, if it has oxidized, it can be repeatedly scrubbed on a wet sponge while being powered on, and rosin soldering wire can be added until the oxide layer is removed. The surface of the soldering iron head must be re coated with a layer of soldering tin. For the cracked and damaged alloy head, it can only be replaced
4 electric soldering iron is an electrical product that, like other electrical products, is afraid of water and moisture. Therefore, when creating a PDF file using the "pdfFactory Pro" trial version www.fineprint.cn or when not in use, it is important to 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 also to ensure safety, as water or moisture can cause a decrease in the insulation performance of electric soldering iron, Causing electric shock accidents
During the use of electric soldering irons, we can extend the service life of the soldering iron head 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 phenomenon is that it vaporizes immediately when it comes into contact with rosin, and the soldering wire turns golden purple (oxidized) immediately after adding soldering tin. If the temperature is too low, the soldering iron head can be moved out of the heating core a bit. If it comes into contact with rosin and vaporizes slowly, the soldering wire cannot melt immediately, You can move a little bit of the soldering iron into the hot core until soldering is added, and it will immediately melt. It is better not to oxidize in a short period of time (15-20 seconds). Note that the length of the 30W electric soldering iron head left in the hot core should not be less than 1.5CM.50W electric soldering iron. The length of the soldering iron left in the hot core should not be less than 2.0CM, otherwise the service life of the hot core will be shortened
