    Do you have pulse parameter controls on your welder? Kevin's
    presentations and my experiments lead me to believe that it is
    essential to have the ability to control your welding current with
    pulse width and frequency adjustments to keep from melting the whole
    piece. Also a spot weld (single pulse) mode is quite helpful. Kevin's
    first presentation at SFS 2006 showed ring shank repairs, re-
    tipping, channel rebuilding and various fabricating jobs done with
    TIG welding in gold and platinum. I have been playing with silver
    and believe that it can be successfully worked this way as well but
    is a little trickier due to its high thermal and electrical
    conductivity.

    I will contact him and see if he has email and is willing to become
    a part of this conversation.
