I had to go to lead-free solder for some objects normally used in the hand
(Walking sticks). I got the Ag-Sn stuff and its proper flux at a local
building supplies store. It is a Tin based solder with a small amount of
Silver to make a near-Eutectic mix, around 3%, I think.
I have had absolutely NO problem using it with a torch or Weller guns of two
different Wattages. In fact I sometimes pre-Tin with the Weller before
clamping assemblies together and making the final fusion with a torch.
After using the lead-free stuff for that, I also used it for UHF connecters.
Worked fine.
