The treatment method of electric soldering iron burnt
1. Intermittent power supply: In the process of soldering, once the soldering iron temperature reaches, the power supply can be cut off to prevent overheating and oxidation.
2. Cooling method: use a cooling stand.
Disposal after burning
1. Use a knife to hang off the oxide layer on the surface.
2. Put the oxidized copper tip into a container filled with ethanol (1-2min), because after the copper oxide and ethanol are heated to produce a chemical reaction, copper is reduced again, and ethanol has no corrosive effect on the soldering iron tip.
