I used the small disposable co2 bottles for my chassis as well and wish I'd have got one of these back then. I must've used at least 5-8 bottles and at £15 a go it didn't work out too cheap. I also tried an argon/co2 mix recently and like you andy wished I'd have used that as I seem to get much better welds with it.

I did a little bit of my chassis with co2 and found it a little cold for me then found my source of the argon mix and wow what a difference

A pub size 10 litre bottle of co2 is about 15 quid

A 50 litre bottle of the argon mix from me is 50 quid better weld less money size for size

Thing is i only use pub co2 as i work for a gas supplies company and i get it free;) , we do all gases but air products are tight fisited gits and even i dont get a discount, but i have a way as i did with an 47l oxy cylinder, just need to wait for a cougar five to pop up;) .
The pub co2 is meant to give a hotter weld, not that i have ever could tell the diffference as i once had a cougar five, this is the equilavent of the BOC argoshield.

The bottle's I can get are all ex air products bottles so you may find mine easier to get filled

Great Service
 

Hi,

I meant to post last weekend when I went to go and get a bottle of VMax, all I can say is thoroughly helpful chap and the bottle of Argon is great.

Certainly better than having to pay rent for a bottle!

Thanks for all the help

Jonathan

Any more wanting gas at stoneleigh so far not enough to warrant me getting the van to bring gas down pm me if you want me to bring you a bottle down

I'm going to on the lookout for an Argon bottle, trouble is I'm a bit far away from you :( stoneleigh is closer but I don't think I can make it to the show.

Just to let people know I just been onto my gas supplier and the price has gone up to so the bottles are now 65 quid each for both the pure argon and the mix will be getting a few argon and the mix in so if anyone is in need of any gas get in touch

Can you do 700 mm Dave ?

The size is one thing the price another , what about contents? How does this compare with say a boc bottle of the same size?
