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.

1, the soldering iron temperature between 320-420 degrees, whether the soldering iron head oxidation, switch off the power with a knife or sandpaper to remove the oxygenated material and can be.

2, why not tin the wire joints? General normal situation is that household appliances are broken you may also use a very long time, the wire part of the connector, in the long time of use when there is current through and external dust into it, resulting in wire aging, oxygenation, dust in the above so you weld on.

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 oxidation, if the above problems have been done, the main look at your wire is enamelled wire, you need to use a knife to scrape off the enamelled wire outer layer of conductive insulating varnish, and then a 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, I would like to emphasise that it is good to do it yourself, but we must ensure safety first!
