Do not know how, when I use the electric iron is not. Solder non stick devices, even if the sticky edge, there are gaps, it is easy to fall off, for example, I want to put a spring in a welding iron, soldering iron and always on the surface of the spring is not smooth, wrap them there is. Then why can't melt soldering iron?Please answer in detail the use of electric iron and the detailed procedures for welding, and what is the rosin, and how it should be used.I'm at the time, thank you.
This is mainly caused by insufficient power of the iron
What's up, you guys? Not for the soldering iron is good?Soldering tin can be used as electrical connection, welding object is copper, silver or tin.Aluminum and iron for soldering.
