Worth having.
I can get away with 7-8lpm through a collet body. Any less and it's starting to compromise quality for the sake of been stingey with gas.
Through a lens I can get away with been as low as 5lpm. (Usually around 6 in most cases. So we are looking around 20% safe drop on flow rates but that's not really the reason I use them. With a lens you get a quality shield. Much nicer than what you would get from a collet body

I can't mate. It's always on the edge for me. On the rare occasions I use them 7lpm + is usually where I am to guarantee it for me.

Of course it does.
I never push things to the lower limit with gas. I'm not happy "getting away with" I'd rather be above it slightly but not excessively as we know too much is as bad as not enough.
6 through a lens measured at the ceramic covers 90% of what I do.
Exceptions for me are joint configuration, tungsten protrusion and front end set up.

It's what I find to be in the "safe shield zone" with a collet body mate. I could get away with 6 I'm sure but 7 offers insurance. The direct flow blanket of a lens puts 6lpm in that safe zone. (I'd get away with 5lpm).

Agreed, this is a DIY forum (which is why I never mentioned stuff I did on Trident subs..........ooops...........lol) Richard, you are correct, 6-8 or 10 lpm, if doing general work and, in your case, self employed, you do what you do to produce quality work for your client. If you can make savings on gas, this is good, more profit to you.
Me, I make my learners aware of how it should be, what you can get away with and, the WPS is bible if doing procedural quality work. I've been there, got the Tee. I've met a few wannabe Brads, I have forgot more than he will ever know..............so I will leave him with the last post, coz I'm out........lol.

That's why the bleeding missile went the wrong way in test
Brad is a good guy and I've personally met him. He can walk the walk with the best of them with a torch in his hand.
Let's all be friends it's more fun all round.

Missile was not my fault, guv, honest!!
Wee true story from last Thursday, first of all, for what we do and, no gas lens kit, I advocate 10 lpm, with reasons for this.
Onto 3mm al/al, usual prep, then butt joint demonstration. I wasn't happy with 250mm long example weld at stop starts. Restarts were not to my liking, so I upped lpm to 12 lpm (shock, horror) what a difference. To the point, if Brads cant see beyond 6 lpm, then he becomes a drone/conditioned, as one who cant think out the box if/when problems occur.
I don't doubt he is a good guy, so am I, this dont make me a bad person because I haven't welded chit for a bloody aircraft, actually I have, I cannae remember name on fuselage

Looks like something I saw mentioned on another forum - pyrex e-cig atomiser reservoirs used as welding shrouds and an extra o ring to hold them on the torch.
I did Richard, but for a wp9/wp24 torch, if you have a gas lens its just a case of finding the right size reservoir on ebay
