How to deal with the burnt soldering iron tip
1. First, wipe with a soldering iron tip cleaner, then repeatedly tin and sponge several times to make it shiny.
2. First, adjust the temperature to 300 ° C, clean the welding nozzle with a cleaning sponge, and check the condition of the welding nozzle. If the tin plating layer of the welding nozzle contains color oxides.
3. Apply a new layer of tin and then clean the solder joints with a cleaning sponge. Repeat the cleaning process until the oxide is completely removed, and then apply a new tin layer.
4. Wipe with toothpaste or polishing paste, be careful not to apply too much force.
Methods to prevent burning of soldering iron tips
1. Intermittent conduction method
Depending on the age of the soldering iron, it usually starts to burn out after being continuously powered on for 15-30 minutes. Therefore, if the soldering iron is continuously powered on for 15 minutes, the power should be disconnected for 3-5 minutes before being reconnected.
2. Cooling method
Using a self-made cooling bracket to cool the soldering iron tip can prevent the phenomenon of "burning to death".
The method of making a cooling bracket is to take a waste metal pen tube, take an empty can (metal shell), cut two-thirds with scissors, clip the waste pen tube into the can with an iron clip, and then inject two-thirds of the capacity of water into the can. A cooling bracket for an electric soldering iron is ready. Inserting the tip of the soldering iron into the pen tube can keep the iron powered for a long time without causing any "burning" phenomenon.
