I guess it's all down to what your experience of it is, I find big bottles ungainly and hard to carry about, but I do a lot of 'mobile' welding, so the little set up is great for me, I don't find that they lose gas when left for a time, but then I don't leave them for long. If I did all my welding at home I guess i'd get a big bottle, but then I'd also get a bigger welder to suit. It basically boils down to what you can work with and get good results with, take all the advice everyone has to offer, mull it over, try a few routes and discover what you're comfortable with. What can work great for one guy can be rubbish for the next. My old mech teacher used to just braze, gas weld and ARC. Wouldn't touch a MIG unless he had to, and his welding was a work of art, but this was back in the 90's and he looked about 80 so I guess that's all he knew.. Just find what suits you best and do that  |

my disposables lost gas when not being used, i guess the regulator that came in my kit was curse word, the hobbyweld cylinder i use now on a deposit only rent free basis shows no sign of losing pressure despite hours of welding practice at a decent gas flow, and they are trimix too, which seems to give a nicer arc and better smoother beading.
I do have a spare disposable argon/co2 bottle and a pure co2 if anyone local wants one for free (both unused)

I started with a straight CO 2 bottle then tried a Argon/CO 2. The Argon/CO 2 appears to give a more delicate/finer weld but the welder just drinks the disposable bottle, one evening's welding used a whole bottle. A CO 2 bottle lasts substantially longer (probably about 3 times longer), it gives a fatter/wider weld so I guess the machine changes other settings between the two gas types. i've heard that before. i think its because when you compress CO2 it liquefies, so you get more CO2 from equivalent liquid size bottle of 95/5 Argon CO2 agree with your observations too, found straight CO2 quite bad for spatter and weld quality |

machine mart disposable argon/C02, 6 minutes continuous welding. 14 quid  same rig with adams gas 9 litre 137 bar bottle argon/C02, 2 hours continuous welding. still pretty mobile. 36 quid (55 quid refundable deposit)  2.5 times the price, 20 times the gas |
