Not quite that way in Canada. If the CO2 is going to be used to power/drive beverage dispensers it must be medical (suitable for human consumption)
grade in Canada. Therefore, I get my tank filled at the local Coca Cola distributor. No worries about quality, done in 10 minutes in my own tank (no exchange) and 35% lower price than a welding supply store. The welding supply srores are exchange (old beater for my newer tankl) or wait at least a week for the tank to go to their plant and return.
