Two torches off one tank?

Hi all,

I have oxygen (M size) and acetylene (B size) tanks. I have a smith
little torch and then also a Prestolite air acetylene torch. I want
to put a Y manifold attachment on the acetylene tank so I can have
both torches hooked up at the same time, ready for different types of
projects. That means having only one regulator on that tank. Can you
use an air acetylene torch with a dual stage regulator? I have only
seen them with the simple single stage regualtors which is what I am
using it with now. My little torch set-up has dual stage. What do you
think? It would be nice to be able to set this up without having to
have two acetylene tanks.

Thanks for any tips!

Hello Carrie,

There is a big difference between single stage and dual stage
regulators, however it’s not the gauges that dictate the difference
it is in the internal workings of the regulator. In a nut shell a
two stage, or dual stage regulator will drop cylinder pressure to
working pressure in two stages and a single stage will do it in just
one. With the dual stage you get much better line pressure control
and very little, if any, line pressure fluctuation. Also a dual
stage has a much larger housing extending out from the tank.

But to answer your question, yes, either way you can hook up a “Y”
connecter and run your ambient air torch, however you will get line
pressure fluctuation if running both torches at the same time no
matter the type of regulator.

Hope this helps.

Carrie, I have been using that type of setup for years. You may have
to adjust the pressure on the acetylene depending on which torch you
use.
