So I've been noticing that when I weld for like a full day at work my clothes or my person are all static-y the next couple of days. I can't tell if it's my old janky clothes dryer, or from all the current going through the welder and everything.

Does anyone have any insight on this? Or am I just too baked?

Keeping a charge for days? Actually that sounds more like your vaporizer may be running too much current.
