Five steps for maintenance and adjustment of soldering iron
1 . For ordinary new soldering iron to bring after, must carry out the necessary checks. 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 the two ends of the plug are short-circuited or disconnected phenomenon, 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 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 firstly install the soldering iron head into the hole of the heat generating core, and tighten the fixing screws of the soldering iron head. Plug in the power supply, the soldering iron is placed on the rosin, as the temperature rises 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, finally in the solder on the head of the chrome head evenly lined with a layer of tin. 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 oxidise, 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 oxidised layer or trim the iron head to the required 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. For alloy soldering irons, if oxidised, the soldering iron head can be repeatedly scrubbed on a damp sponge under power and rosin soldering wire added until the oxidised layer is removed and the surface of the iron head is re-lined with a layer of solder. 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 do not place in the water or humid places to save, on the one hand, can extend the service life of the iron, on the other hand, also in order to ensure safety, because water or moisture, but also to ensure safety, because water or moisture. Ensure safety, because water or moisture will cause the soldering iron's insulating properties decline, resulting in electric shock accidents.
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 vapour, a plus solder solder solder immediately into a gold-purple (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 slow vapourization of the rosin, plus the solder can not be immediately melted, it can be the head of the soldering iron from the heat core, if the temperature is too low, touched by rosin vapour, plus the soldering wire can not immediately If the temperature is too low, the rosin vaporisation is slow, and the solder wire can not be melted immediately, then the iron head can be moved a little into the heating core. Until add solder can immediately melt, in a short time (15 ~ 20 seconds) will not be oxidised as good, note that, 30W soldering iron head to stay in the heating core length can not be less than 1.5CM.50W soldering iron to stay in the heating core length can not be less than 2.0CM, otherwise it will shorten the service life of the heating core.
