What is this?



cup electrode

Jody, what in the Hound is this, all this crud that gets up in the cup and on the electrode. I've pushed the electrode out to get a better shot of the accumulation. Check out all the junk on the inside rim of the cup too.

Thanks much

Justin T.

P.S. The suggested settings are money. I can't wait to get a bottle of helium mix.


wow, that sucks. I am not sure what it is.

possibly some moisture in the argon, or crap in metal is jumping on the electrode
