    I tend to follow the gauge numbers first THEN I eyeball it... bad choice of words.

    I think that's probably how most of us do it. If we feel like we need a skosh more gas, give the know a quarter turn.

    I've always just tested on scrap, and played with the setting until I'm at just a hair more than the lowest setting that gives me perfect welds. Never cared what the number on the gauge said.

    I only do this when I first pic up the torch for the day. After I turn on the gas and purge the line. I don't think sticking the hot bit up by my face is a good idea.

    Ive tried that but I can't tell if its gas or the heat radiating off my glowing red cup....

    Its a problem. Now I just look for the gold sheen in my weld and if its there, I am happy.

    I still put the torch near my cheek to feel if the shielding gas is flowing. But that would be the post flow anyway. Not really interested in tickling my face with the HF.

    They are a cheap way to verify actual flow at the nozzle

    We use one when we have long runs of gas line up to our feeders at elevation and our bottle bank is in the ground.

    You could make your own marks on there once you figure out the conversion. Then you don't have to do the conversion anymore.
