Notes:
1. Please use the tips in the normal temperature range and try to solder at low temperatures to extend the life of the tips.
2. Please always leave tin on the soldering iron tips to reduce the risk of oxidation and make them more durable.
3. If there is black oxide on the tips, please remove it immediately.
4. Never use sandpaper or hard objects to clean the tips.
5. Use a damp sponge to clean.
