I use the new tin clean, also when the tin flux, it is difficult to get my tin, a careful look at the original pen is oxidized, burned black layer, how to avoid this problem is too big, not my electric iron is easily oxidized, there is power, what method can solve the welding head is not easy to be oxidized, and then a case is written is oxidized to do? I don't want to use the knife to scratch, I feel that the use of sharp scraping is very easy to hurt the welding head, master who must not humble, please give a solution, thank you.
When I met the electric iron head is oxidized on tin, with cut iron head according to the plane direction of the original file, and then heated on the lining rosin, give the tip plane tin rosin take smoke, so to protect the iron head is not exposed to the air and high temperature oxidation, prolong the iron head life, the best method is to do this step in the iron head and the newly bought. No, you can try a new one. It is recommended to prepare a piece of rosin at ordinary times. It is better to stick the iron head on the rosin block before the tin is applied, and let the rosin thin and evenly cover the top of the soldering iron, so that the high temperature iron can separate the air and slow down the oxidation rate. Also, try not to have corrosive solder paste.
Insufficient temperatureYou'll have to wait a little longer
First use, tin first, so that the iron head is not easy to be oxidized! Now you can stop the power and rub the iron head lightly with the spinning paper. Plug in the power and return to the tin! Now the iron head is generally anti oxidation of ah!
High power electric iron is easily oxidized, solution: electric iron cold after using sandpaper or iron to iron head and hit the edge and feel clean, plug in the power, when the temperature gradually increased the iron head to stick (rosin), margin.sealing flux on the edge of tin, until full uniform so far. Use is necessary to remember every one will stick a solder flux and, try to keep the head. If the tin oxidized again, can only repeat on the tin.Another way is to pull out the iron head properly so that it does not oxidize too fast, but the temperature is not ideal when used
