So no grinder wheels or the such got it. I have no plans of running my plasma cutter or welder over them, I have welding table for that.
OA and welding gas in general such a pain in the rear, I have an oxygen tank that I've been trying to fill for several weeks now and all the shops give me a run around about it. I guess they want me to rent a cylinder. Oh well, I'm currently using an old school carbon arc torch for my heating and bending needs, it's practically free though not as refined as OA.
