What are the basic points of soldering iron?
Should first use electric iron tin: the red hot iron head to find things clean, and then slightly (such as rosin flux), and then gently rub in the solder, let the plane tip uniform with a layer of tin, after it is used. Before the welding pin on the original also want to use a knife or sandpaper to clean rosin (or other flux) in fast dip, and then iron head with tin, the pin into the melted tin plating a layer of thin water, finally is the formal welding, after the previous preparation, this step is very easy the general look slightly welded shut.Welding points in fact only two: first, the iron to preheat fully two, the lead in advance to tin dust
Aluminium is not welded and rosin is added during welding
Welding for many years, but really did not sum up.The basic point is: the iron head to tin, if rosin, before welding to iron dip solder joint, before treatment, remove the oxide layer, first eat iron tin, then the welding material both eat tin put together with iron welding together, see together, remove the iron, and breathed in the solder joints,.
