I don't know what the exact MP of this stuff is
but my iron (Weller EC
3000) is set to less than 600d and it melts and flows well at that
temperature. I don't know if the temperature control is accurate or not
though. This is 2% silver.
What is the rest of the solder? Tin, lead, something else?
"Silver solder" is an extremely vague term, covering everything from
special low melting point Indium-Silver alloys to 2% Silver/tin/lead
solders to brazing, depending on the context it is used in.
The indium-rich solders are *really* neat stuff, if you ever get a
chance to work with them. Melting temperatures down to near room temperature
are available, as well as entire series of solder alloys with graduated
melting temperatures for building up intricate assemblies. And many indium
solders will even wet and stick to *glass*.
Expensive stuff, as well!
