When you have an acetylene manifold and students with no experience, you don't take safety for granted. Teacher was very experienced and even in technical school with a couple dozen experienced welders, none of them taught us to shut the acetylene off last. I've never read a manual for any torch that tells you how to properly equalize a tip for welding either. They all tell you to set the gauges the same yet the most accurate way doesn't rely on the gauges at all. I guess they don't want to tell you their gauges aren't accurate. [Reply]  [No Email]

That is procedure that Smith recommended back in the early 70's for O/A . Somewhere along the way the oxygen valve was recommended to be shut off first with acetylene. I asked why, and the reply was everything is a fuel, even the copper tip. So if the copper tip is hot enough and you shut off the acetylene first the oxygen can cause the tip to burn and start a fire. I DO NOT AGREE with what I just repeated. My experience with O/A is if the cutting tip is too hot it will pop and go out it will not stay lit. Never had a problem with a heating/welding tip. A couple of times in a paint booth I was cutting out return saddles for the conveyor chain, the tip got so hot it would not stay lit so I cooled the tip by putting the torch head in the water of the flood sheets. All the way up to within 1/8 inch of the flame. The torch was not adjusted improperly, that conveyor is covered with paint over spray so you have the torch in a fire as you are cutting. And yes the fire does get bigger and is put out with water before it gets too big to work in. The second video you posted is for propane. I have zero propane experience so do not know if there is a special procedure, different from O/A for light up and shut down. I did learn something from the Smith video though. Here is a picture of one of the paint booths I have worked in. One of the sprayers in the manual section. Most of the booth is automated. I could not get the picture to post. I need another lesson.

And I think every thing I've read and seen to date says to turn the oxygen off first. But I've been doing this for so long now I have my way of doing things, and it has worked great all these years, so very little I do is up for discussion to change. What I like about Jody's video, (first one) is how he explains about backing the adjustment valve off after each use, and stand to the side when you turn the bottles on. But I had to laugh when I seen he turns the fuel off first. I'll bet I've been around 10,000 weldors in my life, I can't remember a one who turned the oxygen off first. [Reply]  [No Email]

The 10,000 others weldors you have been around turn off the acetylene first. I assumed the 10,000 other weldors may have turned off their torches the same way you do????? [Reply]  [No Email]
