There have been a couple of References to the Hot Spot � jump ring
soldering machine in recent posts. I have been interested in one for
a while, but I notice there is an interesting difference in the
descriptions in the 2003 and 2004 Rio catalogs.
In the earlier book it says "Use solder-filled jump rings for a
cleaner and easier application; you can also use standard jump rings
with a paste solder. In the most recent catalog it only mentions the
solder filled jump rings.
A lot of my interest in this machine had been predicated on the idea
that I could make jump rings of various sized, and perhaps even
different gauge metals.
Has anyone had much experience using these machines with their own
jump rings? Also, are quality paste solders available in other forms
than syringes? I know there were recent posts about making solder
flow out of syringes more easily, but it would be nice to have other
options as well.
