Ok, guys. This is the video I would really appreciate if you watch it & give me a verdict.
The first part is when the welder is turned off and the second part with the welder turned on, and with the same result.
Basically what I did is to open the bottle valve and then shut it allowing some gas to be trapped between the bottle valve & MIG nozzle.
The flow meter is fully opened. Now, instead of the dancing of the ball as in the previous video, the flow meter ball goes up to around 10L/m(the maximum flow rate that I've been able to get out of the flow meter so far, assuming it's accurate), and gradually drops without any dancing as the gas runs out.

So, my question is,
Why the flow meter behaves normally(if you can call it normal) above but totally different when a constant pressure is applied by opening the bottle valve?
Bad regulator? and perhaps bad flow meter as well?
To make sense of what I'm talking about, here is the previous video with bottle valve fully opened.
