Most OC's have, or come with a barbed, tapered fitting so most any 1/4" and 3/8" oxy hoses will just slip-on after removing the brass fitting. The initial downside, is that you are limited to the OC's internally set line pressure of about 7-9 PSI. I used my for several weeks before pulling the OC cover and tweaking the machine's internal regulator - but I'm picky, even though I could've continued using it as-is.
On the fuel side, if your acetylene regulator has a CGA-510 bottle fitting (most mid-sized and larger regs do), then simply screw it on the propane bottle.
So there is no O2 regulator -- you just run the O2 line directly to the torch handle from the concentrator and whatever pressure you get is what you have to work with?
