These canisters last ages and ages and ages. It's been said before in other reviews but worth saying again; simply no comparison to the bottles you get from Halfords which literally last a couple of minutes. These 220ltr bottles are perfect for DIY user with MIG machines that only accept small bottles.
Much much better then the .9 litre bottles more then twice as much gas looks top quality as well ideal for my Land Rover welding repairs at home and should last a while I believe it’s 30 min continuous welding each bottle
It's just the right size bottle for the diy home welder.
The bottle stands up on its own witch is a plus not having to fix it to the back of the welder.
