refill bottle

[Stash]

I have a small co2 bottle for my welder. I want to refill from a co2 soda fountain dispensing bottle anyone have instructions?

Don't. Bear in mind that liquid CO2 in a bottle is at about 50 bar, ie 700 psi. Not for amateurs to play with.

Probably best you leave it to the pros if you have to ask. Theres a reason we all have to pay for refills

Dunno what gas prices are like in the USA but even with the safety considerations aside it would be a hugely expensive way to buy gas over here. Just had a quick look and assuming the fill levels/pressures are comparable I pay twice the price for a bottle ten times the capacity.
