Argon fitting identification

[javascripter]

Started getting a TIG setup and ran into a problem that I haven't been able to figure out how what argon kind of fittings came with the gear I got and therefor how to connect it all together.

Does anyone know of any resources about identifying these kind of gas fittings? I would have expected it to be included in the manuals/other information, but as far as I can tell it isn't the case.

If no such resource exists, does someone here recognize the following connectors?

Here is the connectors I would need to find something to connect too:

as well as one I could just remove and replace with something else, but would prefer not too:

Thanks for any help.

Is the one on the gas bottle removable? As in, on your regulator or on the gas bottle itself?

To identify the other ones you'll need to measure the thread (or the af of the nut maybe) and the diameter of the stem on the 3rd one

first picture is on the bottle itself, might be that I could remove it but I'd really rather not since I believe to get a refill I change that entire bottle

second picture (on the regulator, other side just had something I could put a hose/clamp on) is 1.75mm pitch and ~22.5mm inside diameter (my calipher now is cheap plastic one, but anyway doesn't seem to be anywhere near anything standard), across flats is ~29.5mm

third picture, stem diameter from the machine towards where hose should come is ~8mm, ~6mm, ~9mm, and ~8mm

I also measure the first one at ~7.5mm, ~10 mm, and ~6mm

Your gas cylinder has a built in regulator, it has a special quick connector type that you will need to buy the female adapter for.
One of these

Quick Fit Connector for Gas Cylinder with Built-In Regulator

Quick Fit Connector 3/8" BSP to fit gas bottles with built-in regulators. Manufactured to EN 561-N.

They're quite good, but a real annoyance if you don't have that exact adapter lol. All the big gas companies do a cylinder like that, they all offer their own adapters separately, BOC one is £50! They're all designed to the same standard so should be interchangeable as far as I know.

Pic 1, as has been said is the quick release on bottles with integrated regulators and you should be able to get the appropriate fitting from your gas supplier.

Pic 2 of the regulator doesn't matter as you do not require another regulator.

Pic 3 is almost certainly a Rectus 21 fitting, it is certainly the most common fitting on welders.

Whoever supplied the cylinder will supply you with the quick release fitting... they generally have a 3/8"bsp thread on the back, same as a regulator outlet.

Do you have any gas hose to go between regulator and welder? Suprised if it wasn't supplier with one.

Pic 2 looks like a CO2 bottle fitting. (5/8 gas/bsp)
