Set the flow on the second gauge with the gas flowing, on some gauges the indicated LPM goes up when you let go of the trigger. Some of ours move 5LPM, so a static indication of 12LPM would only be 7LPM when welding.
Hope this helps, Stuart.

You can get a "Pea Shooter" for a couple of quid from places like Parweld and Weldspares etc. They are put on the end of the gas shroud and then you pull the trigger and it tells you pretty accurately what gas flow you are getting at the end of the torch. This is the most important reading, not so much what flowrate your regulator says.
You should be looking for around 10 LPM on small torches, and between 12-15 LPM on industrial applications.

They're about 6 quid Luke. Weldequip's away at the mo and I'm not sure whether he sells them but it might be worth trying diywelding as the postage on the one in my link is nearly as much as the item itself.. You hold it vertically and see whare the ball 'floats' (similar to the ones you see on argon regulators).
