welding regulator question

I accidentally broke the low pressure gage on my argon-co2 regulator the other day. THe tank tipped and the gage got bumped. I tried to get a new gage, but I am only able to find replacement gages for oxyacetylene or high pressure for 75-25. So the question is-what pressure in psi do you think converts to the cfh, and will a low pressure acetylene gage work for this application. ANother thought is that the gage still works, except the zero point is at about 50 cfm now, so I could make that a new zero. I would like to have a more accurate gage though, because the copper tubing in this one is kinked somewhat and I don't trust its precision at all.

go to a welding supply store that fills tanks. you will be able to get a new gauge there.

I'd check with whoever you get your argon from, if they don't have one they might be able to steer you in the right direction.

If you want a more accurate gauge, get an actual bottle flowmeter. This uses the flow of gas to float a ball in a tube, and the gas must be flowing to set it. They automatically regulate the pressure to either 20 or 50psi.
Those gauge flowmeters actually are just pressure regulators, used with a fixed orifice to create the same general effect.
Expect to spend $75 or better on a real bottle flowmeter.
