If you check ebay, there are a lot of regulators there. We sell them as well. They are good units, but are in lpm, not CFH as some desire. They are a good bit less than a SMITH, of which I own one and a prestolite. They work just as good as either of those two.

You could probably violate all reasoning and take out the acetylene nut and nipple ( CGA 510 ) and buy an inert Nut and nipple ( CGA 580 ) They take the Same Nipple which is a Western Enterprise or Superior # 15-3. The nut is different and both use 1/4 pipe threads..Set it at 2 PSI and it would work. Is it the correct way? Not at all. Will it work ? Yes. You can not convert PSI to CFH so turn it down until you get porassity in your weld... Then turn it back up until you dont. Then leave it alone. ( Should you do it? no. Would it work? Certainly..)
