I connected an oxygen regulator (Victor SR 450) to a cylinder. No
hose is attached to the regulator. The high pressure gauge reads
fine. I turned in the adjust screw. The regulator "flutters" or
"chatters" at high flow. Is there a problem?
Is there a better way to test a regulator for proper function without
completely connecting a welding torch?
The low pressure side is trying desperatly to bring the entire room up
to the output pressure you set. You need a smaller space the pressurize,
like the hoses with a torch on the end. This way you can test the
regulator in a static (no-flow) and a dynamic (controlled-flow)
condition. Someone may come up with make shift ways, but this is the
most straight forward.
