When buying o2 for mixing at home is it necessary to buy medical grade or can you use welding grade? I have heard you can use welding grade as long as the purity is good, and also what grade of helium should I buy? Any help would be greatful. -- Send mail for the `techdiver' mailing list to `techdiver@aquanaut.com'. Send subscribe/unsubscribe requests to `techdiver-request@aquanaut.com'.
