I would have thought it’s very unusual to get a contaminated bottle of gas. Presumably they are all filled from a big supply bank cylinder, so if that’s bad, there would be loads & SGS would be aware. It would be interesting to hear SGS’s take on this. Can anyone recall what their forum name is, A…… somethingI`ve recently had my first 50l pure argon bottle from SGS gass and it turned out to be a bad one. The supplier wasn`t too surprised, so I am assuming it`s not that uncommon
You need a bigger cylinder.When this one runs out I think I'll give boc a try they also fill there bottles more, stargas was usually around 200-190 bar I think boc put 230 bar in a 20l bottle ATM I'm going through 3-5 20l bottles a year
Space is my issue for everything including gas cylinders hoping on an extension to the small workshop next yearYou need a bigger cylinder.
Air Products/ BOC have one the best documented record of their gas and bottles.Boc claim their gas has less moisture in it, maybe just a sales pitch I have had to return 2 bottles in the past from my current gas company, we use boc in work and there's never been a problem

Still hoping, but feel it is slipping away, that you might supply here. .. The dreaded Brexit.Hi.
A small explanation of our gas supply!
Firstly all Argon, Oxygen and Nitrogen come from huge Air Separation plants operated by the big international gas companies, so the quality is the same whoever is selling the product.
We buy these gases as liquid, typically at minus 200 centigrade .
The liquid is pumped from our 30 tonne tanks by cryogenic pumps through the vaporizers, that allows the liquid to become a gas, on to the filling manifold and hence into the cylinders .
All of our cylinders have residual pressure valves that retain about 4psi of gas in the cylinder and prevent contamination by water or other gases (such as air!)
All cylinders are attached to a vacuum pump and a 100% vacuum is obtained prior to filling.
Our cryogenic storage tanks and filling equipment cost over £250k and is top quality equipment.
Having said all of the above, we operate a no quibble warranty on our products so if somebody is getting problems with weld quality we always offer a replacement cylinder to the user to rule out the gas as being an issue.
Hope you find the above interesting, I hope the days of back street suppliers decanting gas from larger cylinders or banks of cylinders are over.

Sounds like it was nitrogen, I understand that’s what is used for the smooth flow beers, you know the stuff, supposed to make crap mass produced beer superb, what does it do? turn crap beer into crap beer with a head on!Still hoping, but feel it is slipping away, that you might supply here. .. The dreaded Brexit.
I did use pub gas a while back (actually quite along time ago, late 90s?) until I got a bottle with something extra that made the beer fizz, But really upset the welding.. Used 'Propa' gas since, but 'aint arf dear here.. .
