The following causes carbide to form on the soldering iron tip and rapidly oxidizes the soldering iron tip:
1. The soldering iron tip is kept in a high temperature state for a long time.
2. After completing the homework, the soldering iron tip should be protected by tin plating.
3. Failure to clean plastic parts in a timely manner during the welding process.
4. Clean the soldering iron tip on a dry or unclean sponge or cloth.
5. Is the soldering iron tip covered with carbide flux.
6. Poor coating or solder or welding surface is not clean.
How to restore a lead-free soldering iron tip that is not soldered? The following methods can be used for operation:
1. Lower the temperature of the soldering station to around 280 degrees Celsius, place the soldering iron tip on a damp sponge and repeatedly wipe it with new solder protection without interruption. Repeat the above steps until the lead-free soldering iron tip is shiny and soldered.
2. Turn off the power supply of the soldering iron, use a blade or fine sandpaper to polish off the dirt and oxides on the tin plated surface of the soldering iron tip, then place the soldering iron tip into rosin or rosin paste, turn on the soldering iron power supply, adjust the temperature to around 280 degrees, let the soldering iron tip heat up in rosin, and then use a soldering wire to tin the soldering iron tip. After soldering, find a copper wire or solder suction wire and let the soldering iron tip rub repeatedly on the copper wire until the soldering iron is fully filled.
3. Adjust the temperature of the soldering iron to 300-360 degrees, insert it into the specialized soldering iron tip repair paste, wait for a few seconds, and then use a soldering wire to solder the soldering iron tip.
