    This appears to be a slightly fancier, cordless soldering gun. It
    would use lead solder, not hard solders like we prefer to use for
    jewelry. You might be able to fill the gap in jump rings with this,
    but strength would be less than with silver or gold solder, and
    there would be no color match. Have a good look at a book on jewelry
    making to understand the difference between this kind of melt-on-top
    solder, and a real molecular bonding with hard solder.
