    These are both pulse arc welders which will work quite well for
    joining jump rings the Tack III is more of a bench tool (it can also
    act as a "tack" (capacitive discharge) welder) and the Lightening
    Link Welder is meant to attach to a jump ring fabricating machine
    and is a production machine. They actually weld the rings by
    striking an short duration arc between a tungsten electrode and the
    work. The arc melts the metal ends of the ring allowing them to fuse
    so no solder is needed. The weld is shielded by argon gas so it
    should come out bright and oxide free. The main drawback as you have
    noted is the cost. They are basically TIG (Tungsten Inert Gas) spot
    welders.
