You need to get an adapter, since the threads on the regulator
won't Fit the propane tank.
Hi, My regulator was set up for large acetylene tanks and the
threads were the same as the propane, I would suggest a smaller tank
maybe a five lb… But propane is much cleaner then acetylene.
You’ll need a larger tip for your torch then acetylene.
