I just when the mobile phone repair apprentice, master of the electric iron is always very bright, not black, it is also a touch on the melting temperature, tin, and I always black, on the contrary, tin is not, I think I am not in the process of using and maintenance, please know that the people under the guidance of.
Maintenance can not be discussed, but for the iron hair, black non stick tin can still be solved. Blackening shows that the oxidation is serious. Polish the iron head with fine sandpaper and then turn on the electricity to make it hot. After the temperature of the solder wire is estimated, the rosin is dipped on the head of the soldering iron and tin is added to it. At this point, the iron head is covered with a layer of tin, and the solder wire is concentrated at the tip after melting. It is worth mentioning that it is best not to use the power cut off, it can not allow a long time in the electric heating state, otherwise it will affect the life of the iron head.
Mainly you buy iron head certainly quality is not good, and usually not too high temperatureWhen finished, that is, solder wire, solder wire is also a little better, not too garbage
Hello, electric iron, just in the power supply, the temperature should be adjusted to about 250 degrees, and so on, after two minutes and then transferred to about 320 degrees. Also, during the welding process, it is best not to use the ordinary welding oil is best to use rosin. Don't use soldering irons to heat things like plastics, which can cause great damage to the iron head. Finally, when you are ready to turn off the power, first solder the soldering iron to the tin wire and put it on the shelf, then turn down the temperature, and then turn off the power after a minute. If you do the above, I think your electric iron will not be black than your master
