When shutting off, turn off the oxygen first and then the fuel gas. Nearly every training video I've ever seen has taught the same order for lighting and shutdown. [Reply]   [No Email]

However, with propane it helps to have the oxygen on a little bit with the propane so the flame stays lit if there's a breeze. I don't know what video's you've watched but I think you're confused. Fuel gas first is the same order of doing things. You turn the fuel gas on first so you have something to light and you turn the fuel gas off first to extinguish the flame. Rosebuds often "pop" when shutting off because the head has got a little too hot and there's still a tiny bit of acetylene that didn't make it out the end. Another good reason to shut the oxygen off last is it gives a couple seconds of cooling to the rosebud or tip. [Reply]  [No Email]

Apparently there are two schools of thought on this. I just re-watched the Victor Oxy-Fuel safety video that they have on their website and it clearly shows fuel gas on first when lighting and Oxygen off first when extinguishing. http://victortechnologies.com/Shop_Talk/Victor/shoptalk.php at 29:53 [Reply]  [No Email]

No matter which valve I turned off first. I always turn the fuel off first. I don't like having the tip sooted up. I think the only acetylene rose bud I have left is a #12, I run right at 15-psi with it. [Reply]  [No Email]

I have heard of doing it the other way but it always seems to pop. Fuel off first, the fuel is burned up and exhausted out the tip by the oxy flow. If you shut off the oxy first it will burn back into the torch. [Reply]  [No Email]
