Sorry I fluffed the quote - now corrected. You're quick
Good, consistent welds are important to a business.
That demands reliable gasses.
None of this 'breathing' rubbish.
The grumpier of the 2 in my local BOC is always very quick to point out that they do not condone decanting O2. I always ask him what sort of dive to 6m does he think I am doing with his 90kg cylinder
Remember anything you read on the internet was probably written by some guy sitting at home in his underpants! Including this !!
Illegitimi non carborundum
I have used the industrial helium and oxygen several times. No problems.
The biggest difference is not the purity, but that the 50L cylinders where you get it in are not cleaned for they fill them again. So that means that someone could have drained it totally or made impurities in it. With dive oxygen the cylinders are cleaned before you get them. This is what is told to me.
This is what is told to me. I have never asked it at Air Products themselves or Messer. But I have used industrial oxygen and 4.5 Helium instead of 5.0.
I use welding O2 for all my fills and it's been fine, I always analyse it before use
and I'm happy with the results so far.
I use diving grade helium but I have access to "Balloon Gas" when analysed it was
as pure as diving grade but I have never used it, has anyone? It would be interesting
to know just what the difference is.
