There will be a flow gauge used with it. That's what the regulator I have bought is intended for. Preset for agron and it's matching flow regulator 0 – 14 l/pm. If that doesn't work oh well have to get another. I'd expect to have to tweak the flow regulator now and again but not often enough to be a problem. Depends how good the regulator is. That does vary. I wont go into how I know that.
The reason for the adapter is explained in the 3in1 post. As the person who suggested it mentions it allows both styles of bottle to be used. The flow regulator needs to be vertical.
Anyway I usually ignore trolls. In fact on some forums a moderator kicks them off completely.
Thanks for the 2 useful replies. ESAB isn't out of the question price wise and looks to have an additional adjustment which is likely to be useful. I'll see how I get on with the SIP too. I did use a lift up mask for a while years ago and that wasn't a problem. The first one I bought fitted. I preferred a hand held mask for stick though.
Whoops yes I may finish up modifying one.
