Rubbish soldering

[neilbaker86]

Make sure the wire you are soldering isn't tarnished too.


Copper that has gone dark wont take solder. It needs to be bright and shiny.


You can dip it in vinegar for 10 mins or so before hand which usually removes the tarnish. Then put some flux on it before soldering with a 60/40 solder. Lead-free is harder work for beginners.
