Hello Not having great luck. I have some rolls of bandsaw blade stock. Any hints or tips greatly appreciated. Can flux go bad or get contaminated? It seems the solder melts but doesn't have that nice flow , but instead just lumps up into a nice cold solder joint. I cleaned the joints well , but when I apply the heat til it gets red hot I get this black gunk gathering at the ends of the blades. Is there a different flux for non ferrous & ferrous metals? I've silver soldered before with great success.Thanks. ron
