Maintenance and adjustment of soldering iron
1 . For ordinary new soldering iron to bring after, must be necessary for its inspection. Firstly, check whether the fixing screws are loose, secondly, observe whether the power cord is cracked, exposed copper, broken, and then use the multimeter to measure whether there is a short circuit or disconnection phenomenon at both ends of the plug, and lastly, use the multimeter X10K gear, one foot to touch the head of the soldering iron, and one foot to touch the soldering iron plug at the same time, and the needle of the multimeter should not be allowed to have a moving phenomenon. After the above steps, it can be used.
2 The first time you use a new soldering iron head, you must use the following methods to operate. In order to improve the quality of its use, and extend its service life. If it is a common soldering iron, you must first install the soldering iron head into the heat core hole, tighten the soldering iron head fixing screws. Plug in the power supply, the soldering iron is placed on the rosin, with the temperature rise until the rosin melting, so that the head of the soldering iron covered with a layer of rosin solution. Then press the rosin soldering wire on the head of the soldering iron until the solder melts, and then finally put a layer of tin evenly on the head of the chrome head. The soldering iron can be put into normal use.
3 In the process of use. The working environment of the soldering iron head is very harsh, high temperature, easy to oxidize, flux corrosive, easy to corrode, high hardness of the solder, easy to make it wear and tear, the soldering iron head problems are generally not eat tin (oxidation) and broken. For the soldering iron head made of copper metal, you can use the mixed iron to remove the oxidized layer or trim the iron head to the desired shape. Care must be taken to ensure that the soldering iron is not cooled down and that it is operated according to 1.3.2 when finished. In the case of oxidized alloy soldering irons, the surface of the tip can be re-lubricated with a layer of solder after repeated scrubbing with a wet sponge under power and the addition of rosin wire until the oxidized layer is removed. For cracked and damaged alloy tips, only replace them.
4 Soldering iron is an electrical product, and other electrical products is afraid of water, afraid of moisture, so in the use of PDF documents using "pdfFactory Pro" trial version created www.fineprint.cn or placed not to use, pay attention to moisture should not be placed in the water or humid places to save, on the one hand, can extend the service life of the iron, on the other hand, is also to ensure safety, because of water or moisture. Ensure safety, because water or moisture will cause the soldering iron's insulation performance decline, resulting in electric shock accident.
5 in the process of using the soldering iron, we can adjust the soldering iron to extend the life of the soldering iron head, improve the soldering iron welding quality, the specific methods are as follows: If the temperature is too high, the phenomenon of a touch of rosin immediately vaporized, a plus solder solder solder immediately into a gold-purple color (oxidation) can be the soldering iron head from the heat core to move a little bit out of the temperature, is too low, touched by the rosin vaporization is slow, plus the solder wire can not be immediately melted, then the soldering iron head can be moved from the heat core out. If the temperature is too low, the rosin vaporization is slow, add the solder wire can not immediately melt, then you can move the iron head in the heating core a little in. Until the addition of tin can immediately melt, in a short period of time (15 ~ 20 seconds) will not be oxidized as well, note that the 30W soldering iron head to stay in the length of the heating core can not be less than 1.5CM.50W soldering iron to stay in the length of the heating core can not be less than 2.0CM, otherwise it will shorten the service life of the heating core.
