The tips will have to change. Probably need to locate a few suppliers
nearby to see what the cost comparison will be. I do not know whether
propylene tanks are sold vs. rented. When I looked into it, my
supplier had only acquired rental tanks.
If it's economy that you seek, why not just go get a propane tip and
use that instead of acetylene? I started with propane, never welded
with it, before I bought my acetylene bottle. Propane is everywhere,
even on the weekends.
The barbecue-size 20# tank will run for quite a while or 40# and 50#
tanks are available as well. It's the oxygen that cuts anyway.
The hose may need a change-out from acetylene-only hose to general
fuel-gas hose which will run propane, NG, propylene as well as
acetylene.

Id like to know the differences in using these two fuels for normal
around the farm cutting and brazing.

I understand that propylene is safer, has more in the tank, is
cheaper..and thats all I know.

Ive got an old S/V 100 torch handle and various cutting heads and
brazing tips, as well as an old Union Carbide cutting torch.

I have to change the cutting tips, correct? What about the existing
brazing tips?

How much does a tank of propylene cost versus acetylene?

Is there an issue with my hoses?

Regulators? Can a acetylene regulator be used for propylene?


In the past, an acetylene tank has lasted me a couple years, but Ive
sorta gotten the welding bug and Im doing all sorts of projects now.

Ive got tig/stick welders to weld with, but will be doing some brazing
and silversoldering (band saw blades, brazing cast iron..the usual)

Any good links to any good information or some hints and tips?
