   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. I know that the MP goes up with the higher
silver content. You have to use a blow torch on the silver solder that
they use for air conditioning work. I'll check and see if Kester has a
website and lists the specs for this stuff.
