At that time dirty was cheaper so there were differences. Today all grades are made using the highest volume production method, yielding one grade that passes all minimum criteria. So we are free to breath clean and pure O2 whatever the label. And cheaper is indeed better! Robert M.

The Japanese company, being eager to please, agreed but noted that they would have to set up a special production run to make that 0.01% out of spec to meet GM's requirements. =20 =20 ________________________________ From: Byron and Jean Buckingham [mailto:byronjean@jefnet.com]=20 But, don't do it, welder's oxygen contains too much water, and other impurities.
