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.
