Gas for MIG welding

Anyone know where I can get a bottle of Argoshield for a bit if Migging? Looking at the bigger bottles rather than the disposables, I know there's a deal through VZi but was checking for a local supply/experience first.

Anyone?

you thought of getting the gas direct from BOC as it will prob be cheaper

i get my pureshield argon in a half size bottle through BOC, probably the best way

pecks in ely also deal with BOC

The current VZi deal is through BOC and gives this:
It is for Argoshield Light Gas (a mix of argon co2 and oxygen)

Cylinder size (20 litre water capacity)
filled to 230 Bar Pressure
40kg approx
4.8 m3 of gas (4800Litres)

£ 25.54 per refill for gas
£ 35.77 rental for 1 year (refundable pro rata if cylinder is returned early)

total for 1st cylinder £ 61.31 all in

I did a quick look on the internet and there are deals with smaller refillable bottles that work out a similar price, and I'm not sure if you have to rent out the bottle every year, so I thought I'd check for local supplies before signing up. that said, I've not been through to Elliots in Bar Hill yet. Is the above BOC deal a good price?

... And if you've got a baby welder like i have you'll also need a bigger regulator....more expense

why argoshield light? i would rather use argoshield heavy, keeps the welds cooler, and as most of the people on VZI will be welding cars and stuff that has to be beneficial

So what's the difference between Argoshield light and heavy?...I take it it's not a calorie issue
