I just completed hooking up a Minor torch using natural gas and
oxygen. Works great, but I have a concern. The natural gas pressure
(1/4 psi) is too low to flow through the flame arrester (needs 1/2
psi) that came with the torch kit so we couldn’t use it. Does
natural gas need a flame arrester or is there one built into the gas
meter? If I need one, where can I find one that will pass the gas at
1/4 psi? Thanks.
