Disposible Mig Gas Options?

Hey guys,

 

so i've done a fair few bits of welding stainless steel with the mig and so far i've used pure argon from the small bottles. I've not really had a problem doing this as it seems to weld fine (welded my entire exhaust system and it's not rusting etc on the welds and they flowed nicely) but it is expensive to keep buying the small bottles. I was reading an article that said the best gas for stainless is mostly argon with 3-5% CO2.

 

So i had a look and was considering one of the larger disposable bottles like this one http://www.ebay.co.uk/itm/Argon-Co2-220ltr-gas-bottle-for-MIG-welding-disposable-cylinder-/182607454164?hash=item2a84409fd4:g:lzsAAOxy79JSXUzSas it's a bit cheaper than the small ones. But that is 80% argon 20% CO2.

 

So am i better off with 80/20 or pure argon? as i can see any 5% CO2.

 

any thoughts?

These bottles are ok if you are only going to be welding every now and then, did use them when I had the small mig welder.

As I now have a bigger more powerful pro mig and weld most weeks I get all my gas bottles from Adams Gas as they do rent free bottle unlike BOC.

I'm using a 95% Argon , 5% Carbon Dioxide mix at the moment which works for me welding both mild steel and stainless.

 

The only thing you may find with an 80/20 mix is you will have more weld splatter to clean up on your welds
