I've bought another regulator and a Y shaped splitter so that I can run a purge line and finally stick this reducer onto my exhaust!
The Y piece has arrived and its 3/8" BSP which is the size of the regulator outlet and not the inlet as I wanted so I can run the regulators in parallel as oppose to series.
Does anyone know what size it should be so I can find another, my Google searching skills are rubbish!

You need two flowmeters to go on the Y piece after your regulator, not another regulator. One for the purge and one for your tig.

Crappola I thought I needed two regulators to manage the flow on each branch.
Anyone wanna swap a regulator for a flow meter?

You can pick them up for about £10 each, some on ebay buy it now.

Yeah. I'll have to grab a couple. Just spent £20 on a regulator though

I hate to say I told you so but.... I told you so.

Search for your thread, "Crusty Tig welds"

Never mind. What you can buy on eBay, you can sell on eBay.

Yep. I remember the thread and thats where I thought I'd got two regulators instead of flow meters from.
My fault I know. Measure twice, cut once, still cock it up!
