Hi
I decided to do my own shielding gas argon + CO2 mix and went to get a dive bottle (3lt) to make a contraption, see pics.
The argon transformed the welding. It went from bacon sizzling to a quiet flame-torch sound. The welds are also flatter and cleaner. What a transformation!
Facts:-
3lt argon dive bottle + dive bottle reg + 540lt argon (180bar) = £90
combined y-piece_regulator_flowmeter = £15
pub gas annual rental = £30
pub gas (6.5kg, or 3300lt) = £15
I weld outdoors, mostly still wind, at 8lt/min flow rate
my argon gas supply needs occasional tweak to keep up flowrate
I now can MIG steel (argon mix or just CO2), stainless, braze, aluminium (argon only) so have quite a versatile, and value, set-up.

Sorry I haven't got back to you about the gas you can supply in Glos. If my contraption gets unmanageable I may get back to you to get some proper pre-mixed shielding gas.
