So, I have an opportunity to get some free oxygen and acetylene cylinders so I can finally start my own welding operation in my garage (no 220v). Only trouble is, they're huge and I'm not sure I'll be able to afford to fill them. Anybody know what it would cost to fill a 330cu ft acetylene cylinder? I may get regulators with them to sweeten the deal a little. I've also got to figure out how to get them out of my truck when I get them home without giving myself a hernia. I know I can pick them up, but only a few inches.
