About this oxygen thing, it is not explosive, or on it's own flammable. It is used in conjunction with acetylene or propane to create greater heat in the flame for welding and cutting, also to cut, or oxidize the hot steel. That it is explosive on it's own is drivel. I know because I have used this stuff all my life. You ought to see me light my cig with an oxy-acetylene torch. Cool!
Isn't it explosive because it is under pressure or is in liquid form?
on it's own flammable... ooops on it's own even flammable. That's better.
Oh my. LOL
