What if my electric iron head turns black?
Normal, do not mind too much, electric iron is expendable, can be replaced
The use of iron head long time, black is a common oxidation phenomenon, to solve this problem, there are the following methods,1, no electricity when filing to the oxidation of some black, energized again after dipping tin rosin.2, then put some rosin on the sandpaper, solder, electric iron, electric heating, in the rosin, solder sand paper repeatedly friction, until the light.In order to solve the problem of black iron, you can make a small tin pot (made of small metal cans, bottle caps, etc.). Usually, the iron head is dipped in the soldering tin to prevent the welding head from contacting with the air.
First use the soldering iron to feed the soldering iron. After soldering, use rosin as soldering flux. It is not easy to burn againFirst use sandpaper to polish the wax on the head of the soldering iron. Make the copper head clean and smooth, then place some broken rosin and small solder on a piece of sand paper!When the iron is plugged in, heat it on the top of the sand paper and wipe it by the edge of the rosin!
