Can a はんだ付け iron be heated without oxygen?
はんだ付け アイロン 缶 be heated in the absence of oxygen. Because oxygen is not involved in the heating process of the soldering irons.

The external heat type puts the iron head in the center part of the heating body, because the heat source comes from the outside of the iron head, so it is called the external heat type. The internal heat type of the soldering iron head into a hollow shape, the heat generator is placed in the cavity, so the volume is more compact.
The subject said oxygen, although in the soldering iron heating process does not play any role, but in the interference soldering and shorten the life of the soldering iron or a great "contribution".
In the high temperature state of the electric wire in the oxygen environment will appear oxidation phenomenon, over time the oxidized layer falls off to lead to the electric wire thin, cruelty, shorten the service life of the soldering iron. In addition to the oxygen will cause the molten tin and the surface of the metal to be soldered oxidized layer, blocking the soldering process. For this reason, soldering work is inseparable from the flux, its role is to prevent oxidation.
If you can really create an oxygen-free environment for welding, it will greatly improve the welding efficiency, welding aluminum will become a breeze, but also to extend the life of the soldering iron。
In the actual use of soldering iron should pay attention to the the following points ① choose the right wattage of the soldering iron, do not make the iron overheating, otherwise both waste of electricity will also accelerate the oxidation process affecting the welding ② learn to observe and judge the temperature and fluidity of the solder. When the solder temperature is appropriate, the surface will be very bright If the the surface turns blue quickly, the temperature is too high, need to reduce the wattage or switch to a constant temperature iron. ③Prevent violent vibration. because the high temperature resistant material for the core of the soldering iron is made of ceramics or mica, it is easy to break, so hold it lightly when using it. ④酸性 フラックス is strictly prohibited when soldering electronic components to prevent corrosion and leakage. The best flux is rosin. しかし, when welding steel parts, such as tinning difficulties can be used first with acidic flux to do a good job on the tin, and then carefully cleaned, and finally completely welded with rosin flux.
