Hey guys new guy here. Tried joining different welding forums but for whatever reason they kept saying I was a robot. My question is I just acquired through a friend a set of Harris oxy/acetelyn regulators. They each have only one gauge each. The port I’m assuming is the input has what appears to be a connection for a bottle. On the oxygen regulator on the back it says 350psi max inlet pressure. I know oxygen bottle pressure is way beyond that. Can I use these regulators directly off the bottles? If not what are they used for? I’ll try and get a picture up.

Sounds like what you have is a single stage station regulator.

Do you have a model number or picture?

That 350 psi max means they're definitely some kind of line regulators. Connecting the O2 one to a cylinder could end very very badly.

The model number is 47-15 CL. That’s what I thought after I seen that max pressure. Just wanted to make sure.

If it has a CGA-540 connector, then my guess is it's made to connect to a cylinder. If not, then DO NOT put one on.

Still, I agree with you, because while I have seen plenty of single gauge O/A regulators (I don't care for them though), the gauge almost always is used to show what is left in your cylinder.

I would hate to see what 2000 plus psi would do to it. I’ll just give them back and buy a new set. Thanks. Lots of good info on this site

Thinking maybe getting the Hobart medium duty kit. Can’t find very much about it though other than hobarts website

With a 350 psi max inlet it definitely ain't made for connecting to 2,000+ psi oxygen cylinders. And the CGA stem on used equipment really isn't a reliable guide because they can be changed out. I've got an acetylene reg with a CGA-600 stem on it;)

That'll screw onto a small Bernz-O-Matic propane torch cylinder.

Yep:thumbup:

I put it together so I can run propane instead of acetylene on a portable O/A rig. Aside from the cost difference, which is offset somewhat by increased O2 use, it'll also put out a lot more heat compared to what can be done safely with a MC acetylene. I've ran a #5 cutting tip with it in nice weather.
