    I think what James is getting at is that silver has such a high
    thermal conductivity that you have to hit it with a lot of current to
    melt the site to be welded before that heat is transmitted to the
    adjacent structure. 300 amps scares me though - seems to me it would
    go directly from solid to vapor phase :) 

    Still waiting on parts...
