1. Intermittent power-on: During the welding process, once the temperature of the soldering iron is reached, the power supply can be cut off to prevent overheating and oxidation.
2. Cooling method: Use cooling brackets.
How to deal with burning
1. Use a knife to hang off the oxide layer on the surface.
2. Put the oxidized copper tip into the container containing ethanol (1-2min), because copper oxide and ethanol are heated to produce a chemical reaction, and copper is reduced again, and ethanol has no corrosive effect on the soldering iron tip.
