Correct flashback arrester

[Aurarius]

posting pic of the regulator will serve no purpose as it looks just like a normal welding regulator

But presumably, if they're designed to operate at lower outlet pressures, a more generous portion of the circumference of the dial will be occupied by the pressure range Little torches are generally run at, i.e. 2-8 psi. 2-8 psi on the dial on the regulator I've got (the one in the link) occupies only about an eighth of the dial's circumference, so gauging what outlet pressure you're running a Little torch at isn't as accurate as I'd like it to be.

I can post a image if you want

Yes please.
