[Noisebridge-discuss] let's get a TIG welder

[Ever Falling]

Matt has a point. At the very least you'd need to put down a metal plate or
something to cover the wood (maybe we could coat the floor in the shop with
an epoxy?) because with almost all welding you're gonna get sparks and slag
coming off your piece. Also fumes, not from the shielding gas, but from the
metal being worked on is a legitimate concern. You just might wanna look up
which metals we should disallow from welding like galvanized metal or
chromed steel. I don't think we gotta be OSHA compliant or anything but
safety is something we should take seriously with a piece of equipment like
this.
