Jim,

    I haven't tried the casting alloy but did have an experience this
    week with Hoover's new 950 PD product. I lasered earring posts on
    mountings and while testing them to see if they were attached well
    (old habits never die, even at the laser) they snapped off above
    where they were attached. After calling Hoover's tech guys I found
    that they have noticed a similar problem when lasering the new alloy.
    Their solution is to use argon as a cover gas. Somehow, using the
    laser without a cover gas imparts gases into the alloy in the area
    that was welded causing it to break with a jagged, frosted look. I
    thought I would share this with everybody to save you some time and
    trouble.
