Why do I use the electric soldering iron head does not always eat tin, the inside of the company can use all the solder iron head even around tin, my own, for a few head began to eat tin, over time all black, the temperature is very high, all right,
Power can not be too high, there are hand can not shake, the heart should be stable. Can succeed
When the electric iron is heated, the surface of the electric iron head can not be soldered on the surface, because the copper on the surface of the electric iron head is contacted with the air and is oxidized, and the surface of the electric iron head after the oxidation will appear blackThe landlord can cut off the electricity, and the electric iron is fully cooled. Use a thin sandpaper to polish the iron head slowly, polish it until the iron head is black, plug in the electricity, insert the soldering iron into the rosin, wait for the temperature, and then go to solder.Treatment method:1. solder, can be prepared in advance a small metal cap (small solder metal cover can be used on the solder paste small metal cap, Gary put some small pieces);2. when the electric iron heating temperature on the tin oxide layer on the surface, first with the Xiaoping files to the iron head, when the file to see the bright surface of copper iron head surface, the electric iron head dip solder paste or rosin, can give up the solder iron head;3. tin, you can use the iron head in the small box cover friction for a while, and then let the iron head contact small solder, when the iron head began to solder;4. if the surface of the iron head is not up to the soldering place, then go back to 1, so do it again and again until the surface of the electric iron head is fully filled with solder
An electric iron is wound around a rough copper wire, and the rough copper wire is beveled on it
