Treatment of burnt iron tip of soldering iron
1. First wipe it with soldering iron tip cleaner, then repeatedly apply tin and clean it with a sponge several times until it becomes bright.
2. First adjust the temperature to 300°C, clean the welding tip with a cleaning sponge, and check the condition of the welding tip. If the tin plating layer of the soldering tip contains colored oxides.
3. Plate a new tin layer, and then wipe the soldering tip with a cleaning sponge. This cleaning process is repeated until the oxide is completely removed, and then a new tin layer is plated.
4. Wipe with toothpaste or polishing paste, and be careful to use gentle force.
How to prevent the soldering iron tip from burning
1. Intermittent energization method
Depending on the newness of the soldering iron, generally a soldering iron will begin to "burn out" after being powered on for 15 to 30 minutes. Therefore, if the soldering iron is powered on for 15 minutes, the power must be disconnected for 3 to 5 minutes, and then connected again.
2. Cooling method
Using a homemade cooling bracket to cool the tip can prevent "burn-in".
The manufacturing method of the cooling bracket is to take a scrap metal pen tube, an empty can (metal shell), cut off two-thirds of it with scissors, clamp the waste pen tube in the can with an iron clip, and then inject three Half the volume of water and a soldering iron cooling bracket are ready. Insert the tip of the electric soldering iron into the pen barrel to keep the soldering iron powered for a long time without "burning".
