The use of electric iron for a long time, the iron head is easy to oxidize, forming a layer of scaly things; If this stuff builds up, it will affect the tin, and it needs to be cleaned every once in a while. Here we introduce a cleaning method:
First of all, we have to judge whether the electric iron needs to be cleaned up, the way to judge is to see whether the solder wire will stick to the head of the iron after melting, if not, it needs to be cleaned up.
Remove the tip of the iron with a screwdriver, not every tip of the iron is fixed with a screw.
Remove the drill bit from the drill and install the soldering tip on it.
Turn on the switch of the drill, let the soldering iron tip rotate rapidly, and then sand it on the sandpaper, as shown in the picture.
Because the sandpaper is relatively rough, there will be deep scratches on the iron head after polishing, so it needs to be polished.
After polishing it, reinstall it on the electric iron, it should be noted that do not often use this method to clean the iron, which is very harmful to the soldering iron.
After installation, let's test the tinning condition. The effect is very good!
Do not often use this method to clean, the damage to the soldering iron is relatively large.
Just to provide you with an idea.
