I actually bought my bottle from Barnet welding supplies. I own it outright but can return for a deposit if i start using loads of them.http://barnet-welding.com/
I payed £170inc VAT including a regulator, there prices might have gone up not sure though
yeah ima ring BOC when i finish work! ive allready got argon/co2 mix for my MIG but its not a BOC cylinder which i want for my TIG plus ill probably get hold of a volkzone argosheild light when i can ahha
Assuming you have the space, it's more cost effective to go 'w' size, not much different on rental, but cheaper per m cubed of gas. Not very portable either that may or may not be an issue.
I changed to BOC after I found rent free gets expensive if you start using the machine half regularly.
worst thing about it was that my driving licence clearly states where i live and will be keeping the cylinders GAH! somtimes i feel like just going and getting a smaller cylinder from the local welding shop! not like i was spending £200 or anything guess thats nothing to BOC though
P.S i have a classic mini! not a chance of getting a W in there haha! but if the Y gets used to quick ill swap to a W easy enough to do!
also stevo i had to set up an accout but i was paying cash ahah!
