    Conversion from Oxy/ace to oxy/propaneSo I've got a Victor Superrange II torch outfit

    So I've got a Victor Superrange II torch outfit. Wanting to convert from Acetylene to Propane as fuel gas. Read alot about this. Some say swap the tips, make sure you got a Grade T hose and the regulator is fine. Some say some acetylene regulators use same internal components (seals, diaphragms, etc) as propane regulators and some don't. I have a Victor CSRM 360 regulator. I contacted Esab (has victor line) and this is what they told me via email:

    "Even though the parts are the same with exception of the delivery pressure spring and low pressure gauge. The marking specs state ACETYLENE ONLY. OSHA does fine customers for doing this."

    I take this to mean in my home shop I'm ok using the acetylene regulator for propane because I don't think there is an issue with a different spring and I'm not worried about an OSHA fine in my home shop. If I were a business, I would probably swap it because of OSHA.


    Did I interpret that correctly? Am I ok (safe) using this particular acetylene regulator for propane? Thoughts appreciated.

    Sounds like you have the go-ahead from Victor. I would not be concerned.

    Be aware if you have type "R" hoses the are certified for acetylene only... For proper hose with propane use you should have type "T" hoses.... Using propane with type "R" hose will cause premature deterioration...

    Modern R hoses have been used with LP for many years without problems but it's your call to use R or T at home. I'll use either and have never seen LP eat a hose.

    The Victor rebuild kits are the same soft parts for LP and acetylene. I rebuild my own regulators per the Victor manuals which are available on their website. The heavier springs on LP regulators would be dangerous in an acetylene application, but the light acetylene springs are of course safe at LP pressures. Do not use an LP regulator with acetylene as it's too easy to exceed 15psi.

    Incidentally, the parent company of Victor bought ESAB and killed off a lot of their classic torches in favor of the Victor brand, but tips are available and there are plenty of ESAB torches on Ebay for those who like them.

    I think Colfax Corp. the owner of ESAB, bought Victor (Thermadyne), and combined them, but maybe that's what you meant.
