How to prevent the soldering iron tip from burning
1. Intermittent energization method
According to the newness and oldness of the electric soldering iron, generally a soldering iron will start to "burn to death" after 15-30 minutes of continuous power-on.
2. Cooling method
Cooling the soldering iron tip with a homemade cooling stand can prevent the "burn-in" phenomenon.
The method of making the cooling bracket is to take a scrap metal pen tube, cut off an empty pop can (metal shell) by two-thirds with scissors, clamp the scrap pen tube in the pop can with iron clips, and then inject three Two-thirds of the capacity of water, a soldering iron cooling bracket is ready. Inserting the soldering iron tip of the electric soldering iron into the pen tube can keep the soldering iron energized for a long time without "burning to death".
How to deal with the burning of the soldering iron tip
1. Wipe it first with a soldering iron tip cleaner, then apply tin repeatedly and clear the sponge several times, then it will become bright.
2. First adjust the temperature to 300°C, clean the tip with a cleaning sponge, and check the condition of the tip. If the tin-plated part of the solder tip contains colored oxides.
3. Plating a new tin layer, and then wipe the tip with a cleaning sponge. This cleaning 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 light force.
