Five steps for maintenance and adjustment of electric soldering iron
1. After the ordinary new electric soldering iron is brought, the necessary inspection 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 heating core hole and tighten the soldering iron tip Fix the screw. Plug in the power, 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 press the rosin solder wire on the tip of the soldering iron until the soldering Melting, 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. 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 it must be done under the condition that the electric soldering iron is not powered off and cooled. Afterwards, you must operate according to item 1.3.2. For soldering iron tips made of alloys, if they are oxidized, you can repeatedly scrub them on a wet sponge while powering on and add rosin solder wire until the oxide layer is wiped off. 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. Like other electrical products, it is afraid of water and humidity. Therefore, when using or storing it when not in use, pay attention to moisture and do not store it in a place with water or humidity. On the one hand, it can prolong the 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 decrease, 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 tip of the soldering iron out of the heating core. If the temperature is too low, the vaporization of the rosin is slow, and the solder wire cannot be melted immediately, you can put the tip of the soldering iron 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.
