The iron head automatic soldering machine easy to black and not eat tin reason has a few:
1, the temperature is too high, especially when the temperature exceeds 400 ℃, is extremely easy to make tin oxide
2. When in use will not eat all the tin tin surface
3, in the process of welding flux, solder wire inside too little, will make the iron oxide surface speed, especially water soluble flux at high temperature when very corrosive, will damage the iron head
4, the sulfur content for cleaning sponge iron head is too high, too dry or dirty
5, the iron head contact such as plastic, lubricating oil or other chemicals
6, all the tin wire impure or tin content is too low
In short, there are many factors that cause iron hair black, but a few points above are the main factors.
