Hi everybody,

So I've decided to incorporate a dome loaded regulator into my cnc oxy-fuel process. I've just switched over to propane from acetylene and while I was at it I decided to incorporate one of these babies in there as well. However, now that the regulator has shown up, I have some questions as to hooking it up. I went with a Victor DL-700 and the way I see it, I should be hooking it up like this. Oxygen cylinder --> regulator --> solenoid --> dome loaded regulator --> torch. The only problem that I have is that there seems to be too many ports. There's the one on the front that I would use to charge the regulator using a needle valve, then the 1/2" inlet that I would feed the gas too, and the 1/2" outlet that would go to the torch. That still leaves one 1/4" port. Any help would be appreciated.
