I just recently got this Olsen oxygen acytelene torch setup, and after doing as much research as I could, I got it all set up and set my pressures, and it started making this rattling when I open my acetylene on the torch, so I tried a bunch of things to get it to stop, I couldn’t. I took it to central welding supply, and the guy there looked at it, tightened a few things a little but mostly just turned it on and it worked amazing, then I go home, not touching it at all, then try it, it rattles a tiny bit then stops and lights well, fast forward to the next day and without touching it it’s back to nonstop rattling when the acetylene is opened HELP ME
