DIN inert gas regulator fitting questions.

[casement]

A few quick ones from an ignorant Colonial:

What DIN (standard and number) fitting(s) are standard for argon/inert gas cylinders and regulators?

What are the standard pressures such cylinders supply?

Recommend me the best quality regulators and suggest vendors who ship overseas.

Thanks in advance!

Argon/mix tanks have a CGA 580 fitting.

Standard pressure is usually about 2200PSI.

Thanks, but Compressed Gas Association is US standard. (Western Enterprises is the main supplier of fittings and adapters in the US should you need any.)

I'm looking for DIN info and asking here since this is primarily a UK forum.

 

[shenion]

Yet, you show and address in the US.

I think argon cylinders with DIN standard fittings are mainly used for diving.

BS EN 562 ......ISO 5171 are the standards for welding related regulators up to 300 bar.

"Just up the road" from you in fact. South Carolina. (For US info I go to Weldingweb/Millerwelds/Hobart forums/Shop Floor Talk and Weldfabzone.)
Hence my comment:

A few quick ones from an ignorant Colonial:

The high-pressure DIN fittings for dive tanks are available in the US as they are used for inflating dry suits etc, but I don't know the specifics of how to order a quality off-the-shelf DIN-inlet argon welding regulator.

I'm attempting to answer a question from a welder who deployed with US-spec gear to Afghanistan and has a bunch of mystery valves on his argon cylinders. I doubt he has the luxury of our local welding supply stores. Don't want him hooking up a low-pressure reg to a high pressure cylinder with a field-expedient adapter.

Recommendations such as "BOC model/number with DIN-whatever fitting would be a great starting point.

So welder goes to Afghanistan with his gear and can't hook up his regulators to the gas cylinders used there. The mystery valves... are they definately DIN or a mystery?

In the UK cylinder valve outlets/connections are BS 341, BS 342 no 3 being the usual suspect for argon etc. Regulator is 5/8 BSP entry, 3/8 BSP outlet
DIN 477 pics here, i think DIN 477-6 is the usual fitment for argon/argon mixes etc

 

[casement]

Awaiting confirmation on the valves, with pics I hope. It's possible they might be BS. I suspect they are filled in Pakistan and trucked in and doubt A-stan has an argon plant.

Thanks for the info, I'll look 'em up!

Got a favorite regulator brand?

 

[hotrodder]

Not really, between workshop and home there's several brands... Harris and Wescol are two that come to mind, probably BOC regs on something too

Thanks much!
