Following the recent purchase of my Calvinx TIG welder i need the above.

Don't mind if it's empty as i should be able to get it re-filled, would prefer full size (about 5ft tall) bottle.

at a push would also settle for Argoshield bottle on the basis that i could "disguise" it to get it exchanged.

I'm in the North East but don't mind travelling to pick it up

Like perverbial rockin horse do-do.
Thes are rent only and so people who rent them are not going to give you them.
You might find someone who will sell you the gas, but they would only do this if they knew they were getting the bottle back !

I've got an S size Argon cylinder that is empty that you can have. Problem is that I'm in West Yorkshire.

Cylinder sizes

Thanks Carl

Will send a U2U

Would still like a full size bottle as that's the one that afriend has an account for and can exchange for me.

U2U me as I bought a mig set with a full bottle from a guy in Perth & he had a spare empty bottle. It may be too far for you to travel though.
