   I just got an answer from Kester. Here's what they said:

"Electronic Silver Solder is a trade mark name. The alloy is Sn62Pb36Ag02
(2% Silver). The melting range is 179 - 189 deg C (354 - 372 deg F).

The rosin flux inside the wire is Kester 44. Information regarding Kester
44 cored flux can be found on"

   As you can see, it melts at well under 500d F. BTW one the things that
I love about this stuff is that it leaves very little flux residue.
