Ok, cool. I'll try with slightly open bottle, but from memory, the regulator pressure meter jumped all the way to 25Mpa from memory, even when I opened a little bit.Quote:

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.

Saying video is not found sorry mate.Quote:

Mine bounces a little but settles after a bit of consistent flow.
However.
If you can hear the flow and feel it on your cheek you have enough flow..
What size wire are you running??
Westy might be onto it , only open the gas bottle max half a turn not full , the first video is how it should behave second is abnormal mate and explains the crap weld but I'm still worried about the rapid torch movement .
Try it again only opening as Westy says quarter to half a turn .
Have you checked your email mate I sent you this info yesterday .
If you meant the bottle, it's size D.Quote:

What did you mean the video is not found? Not working on your end?
It seems ok from my end.
Thanx
Ok, cool. I'll give it another go now and see how it goes.Quote:

Is it normal?
I was thinking the gas valve in the MIG welder is activated electrically, when the trigger is pressed on the MIG gun.

Yea video is not working.Quote:

Thanx mate. I'll try a thinner wire(0.6mm?) then, and see how it goes.Quote:

Videos are working fine. Something's not right with your end, perhaps the youtube app in your phone may be playing up.
Thanx for the email mate, but I didn't check it. I'll check it shortly.Quote:
