I was using my little OA setup today to do some repair work on a snowblower. A couple of times, my acetylene regulator would start pulsing, and the pressure would vary by a couple of PSI. It was making noise like a spring popping.
I've never had it do that before. I was working outside in 35ish degree weather. I was able to get it to stop by varying the pressure, and then putting it back where I wanted it.
The OA unit is a Victor that I use very infrequently. It was purchased new 10 years ago and has always been stored inside. I'm still on the original tanks of gas, that's how low my usage is. I do loosen the regulators when not in use as I was taught in my basic welding class.
Any idea what is happening? Am I low on acetylene? Or is it a regulator issue?
Thanks for any ideas,
