I'm looking to upgrade my single flow argon regulator to a dual flow setup. Has anyone used the Smith 33-50-580 Dual Flow Argon Regulator and what do you guys think about it? (I want this for stainless steel pipe backpurge work)..

Hi, MeatHead,
I actually just built my own. I took two regulator/flowmeter assemblies, unscrewed the flowmeter component from both, and made a simple manifold for both flowmeters from standard pipe fittings and screwed them into one regulator body. As I started with used components, I don't think I had $30 in the whole setup, and it worked like a charm.
I haven't priced the flowmeter you mentioned, but it might be worth considering.

Hi Steve,
Do you have picts of your home made dual flow meter regulator and would you upload here? Maybe I'm going to make one like yours. Thank you Steve.

Okay, here's a couple of pics--
I started with two Smith two-piece regulator/flowmeters. The nipples between the tee and each flowmeter are the original ones with the restricting orifice, while the new nipple between the regulator and the tee is a normal full-flow nipple. Use teflon tape or a good quality pipe dope, and check the connections with soapy water. (Actually, any time you hook up to a bottle, you should to this at the bottle connection AND the bottle's valve bonnet. Be sure the valve is opened all the way, as there is a positive seal in that position on all high-pressure bottles.)
Since the changes are downstream from the regulator, plain 'ol standard duty hardware store parts will do. Here in the U.S., all the fittings are 1/4" NPT.
If you wanted to do the same thing with one-piece regulator/flowmeters, you could tee at the bottle fitting before the regulators, BUT you will need to use AT LEAST sch. 80, preferably sch. 160 nipples and fittings to withstand full bottle pressure.
The purge line draped around the flowmeters in the last picture is actually a super-flexible gas hose from a water-cooled torch.

You're welcome.
Give yourself some credit. You write English better than some of my friends speak it.
What is your first language?
