Introduction of five steps for maintenance and adjustment of electric soldering iron
1. After the ordinary new electric soldering iron is brought, necessary inspections must be carried out. First, check whether the fixing screws are loose, and then observe whether the power cord has cracks, copper exposure, damage, and then measure the two ends of the plug with a multimeter Whether there is a short circuit or an open circuit, the last step of the multimeter is X10K, one foot touches the tip of the electric soldering iron, and the other foot touches the plug of the electric iron at the same time, the pointer of the multimeter is not allowed to move. After the above steps, it can be used.
2 When using a new electric soldering iron tip for the first time, the following methods must be used to improve its quality and prolong its service life. If it is an ordinary electric soldering iron, you must first install the soldering iron tip into the hole of the heating core, and tighten the soldering iron tip to fix it Screw. Plug in the power supply, put the soldering iron on the rosin, and as the temperature rises until the rosin melts, the tip of the soldering iron is covered with a layer of rosin solution. Then put the rosin solder wire on the tip of the soldering iron until the solder melts , and finally after the solder is evenly coated with a layer of tin on the head of the chromium head, the electric soldering iron can be put into normal use.
3 During use. The working environment of the electric soldering iron tip is very harsh, the temperature is high, and it is easy to oxidize. The flux is corrosive and easy to corrode. The hardness of the solder is high and it is easy to make it wear. Tin (oxidation) and damage. For the soldering iron tip 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 not be turned off and cooled, and it is completed. After that, you must operate according to item 1.3.2. For soldering iron tips made of alloys, if they are oxidized, you can scrub them repeatedly on a wet sponge while energizing and add rosin solder wire until the oxide layer is wiped off, and the surface of the soldering iron tip should be re-enamelled. The last layer of solder. For the alloy head that has been cracked and damaged, only replace it.
4 The electric soldering iron is an electrical product, and like other electrical products, it is afraid of water and moisture, so when using the PDF file or storing it when it is not in use, be careful not to get wet Store in a place with water or humidity. On the one hand, it can prolong the service life of the electric soldering iron. On the other hand, it is also to ensure safety, because water or humidity will cause the insulation performance of the electric soldering iron to decline, causing electric shock accidents.
5 During the use of the electric soldering iron, we can prolong the service life of the soldering iron tip and improve the soldering quality of the electric soldering iron by adjusting the electric soldering iron. If the soldering tin turns golden purple (oxidized) immediately, you can move the soldering iron tip out of the heating core. If the temperature is too low, the rosin vaporizes slowly when encountering the rosin, and the solder wire cannot be melted immediately, you can put the soldering iron tip in the heating core. Move a little in. It will melt immediately after adding solder, and it will not be oxidized in a short time (15~20 seconds). Note that the length of the tip of the 30W electric soldering iron in the heating core should not be less than 1.5CM. 50W electric soldering iron The length of the soldering iron left in the heating core should not be less than 2.0CM, otherwise the service life of the heating core will be shortened.
