How to use a soldering iron for the first time - how to use a new soldering iron
New soldering iron for the first time to use, heating to the beginning of melting solder wire should be placed on the soldering iron head to let the solder melted in the iron head surface, to prevent the iron head oxidation is not on the tin. Can also be coated with a little solder paste or rosin. After this treatment, the soldering iron head is very easy on the tin, there will be no "tin ball" a shake down the situation. Secondly, to weld the parts, the first to do to oxidation treatment, is to use a knife to scrape clean the surface of the oxidized layer of the welded, coated with a little solder paste or rosin, and then at the same time, the solder wire and the soldering iron head on the welded parts, melting a little bit of solder wire, it will be able to weld the very good.
There are two kinds of soldering iron head materials, ordinary head is selected copper as the substrate; long life head is the soldering iron head plating, that is, in the copper surface plated with pure iron or nickel, its life than the ordinary head of about twenty times higher, and is not easy to deformation. The soldering iron head tin eating steps are as follows.
①Sanding or rubbing. Ordinary head can first use sandpaper to sand or file file, sanding the length of the height of the beveled surface a little longer, must be careful, until the plane is clean, smooth as good. Then use a clean, dry cloth to wipe. If the long life head can not be sanded or filed, only with a clean, dry cloth sassafras.
② Eat tin. Prepare a small box of rosin (solder wire contains rosin, but the amount is too small, not easy to eat tin), turn on the power plug, wait a few moments after the head of the soldering iron will be hot, use the soldering iron tip dipped in touch with the rosin to estimate the temperature. Just can melt rosin, that the temperature is still low; rosin white smoke and iron head purple serious, that the temperature is too high; only rosin can quickly melt and not a lot of smoke, the temperature is optimal. When the temperature of the soldering iron head reaches the best, evenly make the soldering iron head dipped in rosin. The soldering iron dipped in rosin should quickly melt the solder wire on the soldering iron frame plate to make a large soldering point (and then add a little rosin), the soldering iron head repeatedly submerged to rotate the soldering point until the soldering iron head polished part of the whole uniformly ate the tin.
③ Aging. After the soldering iron head to eat tin, the soldering iron should be aging. Aging is not to use the soldering iron for the time being for soldering, so that it continues to power heating for a while, and then unplug the power cord, placed in the soldering iron on the shelf to make it cool naturally. Aging can extend the life of the iron head and iron core, especially the new iron head and iron core. Eat tin, aging after the soldering iron, later can be used normally.
If the normal use of the soldering iron, in a new round of power welding before, should also check whether the iron head "burned" or "port mutilation" and other phenomena. "Burned" refers to the soldering iron head to eat tin parts have been oxidized, turned into a charred black head, no longer dipped in tin or dipped in tin ability is very poor; "port mutilation" refers to the work surface convex and concave deformation or cracks and so on. These two situations need to re-tin iron head.
