    tommyd,

    I have seen it as it happens to me as well. Not sure what causes it.

    This is not in the weld pool it go all over the metal after you stop welding

    You got me thinking and the best answer I have is silica that is precipitating out during the weld. This is a best guess, post a picture if you can, that may tell something different. I have read through my books and nothing else seems likely. If it's silica then no problem.

    Peace,
