If you're only doing a couple of small patches isn't it worth just getting a couple of the disposable ones from Machine Mart or similar?

I happen to have BOCs price list in front of me!

It costs £25.91 for a bottle of CO2 plus £6.46 a month to rent the bottle!

That's a sheildpack 6, I don't actually know how much gas it holds but it stands about 2.5 feet tall!

ahh someone told me it was about £150 to open a new account :/ might be something worth looking into afterall!

You can find out your nearest supplier online!

Wee bit of a hi-jack but where do most people get their gas from? i'm really struggling to find some gas locally as the wine shop i got my bottle from has closed down and none of the brewerys will refill it!!

I can get some from BOC but you need to open an account which i've been told you have to pay big bucks for [out of my price range anyway] i'm only getting the gas so a mate can do a couple of patches!

wandering if theres anywhere that does deliveries at a reasonable price?

If you have been reading this thread you will see that i have a contract with B.O.C and as i mentioned if you return the bottle with say 11 months of a years contract left you will get that refunded. So not that expensive plus they do different sizes of bottles and some are cheap. Try them for a quote it may surprise you.

I used BOC Arogoshield light for welding my whole mini..really nice welds, and plug welds are very tidy. I guess your technique will count for most success but the Argoshield gas does leaver smoother welds.
If you are practising welds I would use C02 as its cheaper so you can practice the technique. When happy, use argon mix and adjust your settings to suit this gas. A good weld is based on things like gas flow, how quickly you move the torch, current etc. You will find that your touch and feel will develop, and no one can really teach you that. The different gases are just for different materials, thicknesses etc.

But anyway the final welding, I would recommend Argon mix (Argoshield light - for thin steel, if got from BOC).
