Some guys colloquially call regulators "gauges". I am not one of them. Most welding regulators have two gauges on them. One is high pressure and the other low.
I buy quality regulators when I see them cheap. I see a lot of them. What I am wondering is what causes the problem when a gauge doesn't quite return to zero. Is it repairable? Does it necessarily mean the gauge is inaccurate?
Thanks,
