Regarding the use of soldering iron sponges, I found that some friends still didn't pay attention, and the method was incorrect, which caused problems with the soldering iron head. You should pay attention to the following 2 points when using a sponge containing Taiwan:

   1. Humidity: The correct degree of dryness and wetness should be to soak the sponge with water, and then squeeze out the water by hand, and do not have 'open water' as the appropriate humidity!

   2. Wipe: Pull back at a 45-degree angle, wipe repeatedly, and immediately tin the soldering iron tip when you see a bright white background.

In short, the role of the sponge is to wipe the residual tin and oxide on the tip of the soldering iron. It is found that the moisture is less and more.

 When we use the soldering station, we should first put the yellow heat-resistant sponge in the water and soak it. He will quickly expand to pick it up and wring it out. After turning on the power of the soldering station, we first adjust the temperature to 200 (generally within the range of 200-350 degrees). If the duration is too high, the heating core will burn out. During the heating process, we insert the soldering iron head into the rosin Then, take out, when the temperature is constant, use tin wire to dip the tin on the soldering iron head, and then rub the soldering iron head back and forth on the heat-resistant sponge to make the tin evenly coated on the surface. Then send the handle back to the soldering iron stand and leave it on for 15 seconds. At this time, the soldering iron will be black, which is oxidation. As long as it is used for a period of time or after not using air burning, as long as the oxidation is black, you must maintain a good habit: timely rub back and forth on the heat-resistant sponge to remove the oxidation Layer to maintain the thermal conductivity and life of the soldering iron tip.

We can only introduce the use of the sponge on the soldering station here. More precautions still need to be followed by every operator to extend the service life of the equipment.
