From http://www.kevincaron.com - Artist Kevin Caron usually uses his plasma cutter for cutting metal, but sometimes the oxygen-acetylene torch is better for the job. It's easy to use - watch to see how. See more how to videos at http://www.kevincaron.com

Hi Kevin; I like your videos, but this one contains a pretty glaring error: You state that a O/A cutting operator should open the valves on both tanks a "quarter turn only". That may be correct for the acetylene, but most definitely NOT for the oxygen cylinder, as you must turn the oxygen tank's valve ALL the way on, since oxy valves are double seated (if not opened completely the oxygen will actually leak from around the valve stem's o-ring due to the immensely high pressures).

@cottersay I keep getting conflicting answers on this point. Some say 1/4 turn others say full open.

Thanks for posting.....

@kevincaron I too have seen the "open 1/4 turn" for oxy, but typically only in books for metal artists. All of the "open oxy fully" comments were in hardcore welding books. Just two I found:

"The oxygen valve is opened all the way until it becomes tight ."

'Welding: Principles and Applications', 7th Ed, Jeffus

From Stanford University:

"Open the main valve on the oxygen tank. Turn the valve until it is fully open (until it stops turning)."

Thanks for your great videos Kevin!

Update your valve turning habits!!
