Hi i bought some of that thick 12g silver wire and am having a hard time soldering with it. any tips?
You said "soldering with it", not "soldering it". I may hasve misunderstood but you aren't trying to use the silver wire FOR solder are you?generally when people speak of "silver solder" it is one of two things:
1: brazing rod used with an oxy acetylene torch and powdered flux, like what plumbers use to solder copper pipes together.
2: Tin:Lead electronics solder with about 2% silver added.this tin lead silver solder came about from the ceramic terminal strips used in the earlier Tektronix scopes. If conventional solder was used a few times it would leach the silver out of the special alloy that was stuck to the ceramic and degrade it.
NEVER use ROHS solder. it'll give you trouble in about 20 years as microscopic whiskers of tin grow from the solder and short things out.
"tips" may be the issue. That is a massive chunk of silver that conducts heat at a furious rate and needs a big solder iron tip to get solder to melt. I found one needs to get teh tip hot, load it with a bit of 1-2% silver solder and then use that to heat the end of the 12g silver wire to get the solder to flow into the join. It doesn't take long if teh heat is there.
