If the head of the soldering iron is not tinned, what to do?】
Soldering iron head is not tin because the soldering iron head surface temperature is high, in contact with air is very easy to oxidise, once the formation of an oxide layer is very difficult to tin, so we encountered this situation only need to use a razor blade to gently scrape off the oxidised layer, and then sandpaper to polish a little, to be exposed to a clean tin surface after heating, and then use the solder wire will be uniformly coated with a soldering iron, so that the soldering iron head is wrapped with tin will not be easy to oxidise! The following is to share with you a little bit about the soldering iron. Below to share with you the precautions for the use of soldering iron.
First, the soldering iron head at high temperature in contact with the air is very easy to oxidation, as long as we always keep the iron head with tin package can largely prevent oxidation, to avoid the phenomenon of paste head.
Third, try to avoid using the soldering iron hot soldering tin wire outside things, such as plastic, etc., because the soldering iron head once stuck on other materials, will certainly cause paste head not on the tin.
Fourth, the soldering iron is just a heating tool, we should try to avoid using the soldering iron to pry the components of the foot, because it is easy to form a trauma to the head of the soldering iron, once the head of the soldering iron deformation, we need to use a file or sandpaper will be the head of the soldering iron to sand flat and then use.
In general, the maintenance of the soldering iron is actually for the soldering iron head, as long as we usually pay attention to avoid the dry burning of the soldering iron head can be, as long as to ensure that the soldering iron head is always above the tin package, there will not be on the tin.
