Soldering iron soldering wire connectors are always unstained
Their own is not a professional repairman, sometimes home appliances are broken thinking of repairing their own, but with a soldering iron soldering wire joints are always stained, solder is not sticking to the soldering iron is falling down, is not stained wire, solder paste is also used or not stained.
Soldering iron in the process of use, often does not stain the solder or even melt the phenomenon of solder, at this time you see the head of the soldering iron must be black, this situation shows that the head of the soldering iron has been oxidized, commonly known as "burned to death". Encountered this situation, do not use a knife to scrape, also can not file file, so as not to harm the soldering iron head (tip) the tip of the alloy layer, must be dealt with by the correct method in order to continue to use. The following two solutions are effective.
One of the solutions: wipe
Find a piece of the following chart shows the high temperature, water expansion rough cleaning sponge (Ms. maintenance face grinding face that, or go to the electronic shopping mall tools counter to buy), soak in water, to be its instant expansion, pinch off part of the water, and then has been heated soldering iron head in its one by one to rub, at the same time, also take the rosin contained in the soldering wire to the soldering iron head on the rub, and so on repeatedly until the soldering iron head shiny tin-plated good! So far.
Solution two: rub
Slightly force, will be heated in the soldering iron head, in the solder wire melted into a block of solder on the repeated rubbing. In the meantime, from time to time, the soldering iron head can help soldering and decontamination of rosin block on the dissolution of rosin plating, the above action repeated many times, the soldering iron head will be as bright as new, very good.
If the above does not solve the problem, then you will need to question your soldering iron tip and the amount of solder wire you are able to get. The former is very shoddy and the latter has very little tin, melts like tofu dregs, and the solder joints are gray and dark, both of which are sold at low prices.
1, the temperature of the soldering iron between 320-420 degrees, whether the soldering iron head oxidation, turn off the power with a knife or sandpaper to remove the oxygenated material and can be.
2, why is the wire connector not on the tin? General normal situation is that the household appliances are broken you may also use a long time, the wire head part of the joints, in the long time of use when there is current through and external dust into the, resulting in the wire head has aging, oxygenation, dust on it so you weld up.
3, normal welding is the soldering iron temperature of 380 degrees or so, welding wire head temperature appropriately high, no problem, the soldering iron head is not oxidized, if the above problems have been done, the main look at your wire is enameled wire, need to use a knife to scrape off the outer layer of conductive insulating varnish enameled wire, and then a little bit of tin on the head of the wire can be firmly welded.
4, the soldering iron does not need to turn off the power when the soldering iron head a little tin, do not get off, to prevent oxidation of the soldering iron mouth so that the next time you use the time to let you be at ease. Finally want to emphasize a sentence, do it yourself is good, but must ensure safety first!
