​In high temperature soldering iron head for a long time, can lead to surface oxidation, iron non-stick tin, can at low temperature, use sand paper burnish, then with the increase of temperature, stick a little rosin and soldering, will every surface polishing, finally each plane has a solder. Form a good habit is the most main, after each use to keep welding head with solder.

Good soldering iron head has a layer of alloy solder, specially the inside is copper. Of course, also can be used if grind alloy layer, easy oxidation and the copper loss, molten tin can dissolve a small amount of copper. But amateur is certainly no problem.

We use soldering iron should always maintain has tin welding head of state. For amateurs, the rosin is must be some, you'd better use the alcohol dissolve the conditions allow rosin (after the soluble rosin can open to put, eventually forming paste).

Used for the first time is critical, the general should be on rosin, after electrify can see after the temperature up, rosin was melted away slowly. When soldering iron head is stuck with rosin. Take it out, wait a minute, the temperature of the soldering iron can melt tin it.

Put the tin wire coated iron head, for a moment you can see the tin melting and scattered throughout the soldering iron head.

In addition, you should be ready to sponge (like rosin, selling soldering iron should be). Dip in water, see the welding head black wipe off is just above. Wipe again after you remember on the tin.

After using the soldering iron, best again in add a little tin soldering iron head.

Temperature not too high, the welding head repeatedly in the sponge, the high temperature of dip in water, and then put the welding head on the rosin on the tin. If severe oxidation, find broken insurance tube head, inside put rosin, soldering, welding head in high temperature on the sponge first, and then into the insurance within the first heating solder, the solder melts repeatedly with welding head inside rub (clamp insurance with forceps head ceng) with some force, melting of solder height to high need tin welding head.In high temperature soldering iron head for a long time, can lead to surface oxidation, iron non-stick tin, can at low temperature, use sand paper burnish, then with the increase of temperature, stick a little rosin and soldering, will every surface polishing, finally each plane has a solder.
