Does anyone on here use a flashback arrestor on your forge burners? Or do you think that would restrict gas flow too much. Im in the welding sup. ind. and they are common(and getting to the point of being required by ins co,) on torch outfits, but the gas flow is much less. Was just curious, and thought it would be a good idea, but so far im still playing with my burner setup.

It wouldn't restrict gas flow too much, if a big acetylene rosebud can run 10 psi with one, I think a forge would do fine.
I don't think it's necessary, however. I've not heard of them being used, and I don't personally. Not that that means anything, but oxy and ace are both more volatile gases than L.P. When I shut the forge down I purge the line as I would with a torch, but have never experienced flashback with propane. I have with welding gases.
Just my 2 cents.

IG has the answer.....it is the gas type.
LP ( and natural gas) has a much more stable rating than acetylene, and is used with atmospheric burners, or low pressure air. The high pressure oxygen and the unstable nature of acetylene makes flash back arrestors needed for welding, but not for LG setups. If it was an issue, every BBQ grill and kitchen stove would have them.

Ya my understanding is they are important where there is the pressurized oxygen that can "cross over" into and back up the fuel gas side. Never heard it being an issue otherwise. Fuel tank orientation, location (relative to the forge/fire/combustion) and piping/hosing of the fuel is paramount to consider!
