No, I'm not switching religions, I've been thinking of going propane, rather than acetylene. What do I need to change on my torch setup?

I use the standard twin hose. But you will have to unscrew the acetylene bottle fitting from the regulator, and put in a propane spud.

Propane may eat the lining of acetylene hoses depending on the age and manufacturer.
IIRC there is a "T" in the propane rated hose part number.
This is from memory when I converted about 25 years back newer hoses may all be propane rated.
FWIW I converted back as I do not use the torch much for cutting any nore and O-A is much better for fast spot heating.

Yup, T-type hose sets are propane rated. But, Gerry called me on this years ago and I have to admit I'm still running running R grade hoses cause I seldom fire up the torch and no problems yet. But, for every day use you need T-type hose sets.https://www.atlweldingsupply.com/blo...n-welding-hose

From what I understand about pane, if left in a hose for a long time in the sun, propane will be cracked by the heat into something that attacks some rubber compounds.
I don't leave my tanks on and don't leave them outside.
My propane truck driver told me this as I have a rubber propane hose feeding the first stage regulator to the house. He advised to use copper. Someday I will change it.

Many thanks, fellas. For the little bit I use a torch, it doesn't justify the expense

Only liquid Air regulators have their own style fitting. Any other brand will fit into the propane valve. Just a new cutting tip is needed to convert to propane.

Dang, You thread title scared me. My first thought was you were converting to liberal!!!!

I made a propane setup and all I did was get a propane cutting tip from my auction takes. Used set of O/A hoses. Everything works great.
