Just getting into Oxy Acetylene. I’ll go with your video. Sounds like you know what your taking about. Too many people should not be posting videos on such a critically safety oriented topic. I usually view a half dozen videos so i can kinda weed out the good, the bad and the ugly.

Excellent Video Gray! as a jack of All trades, I really need to do things in a general way. I have no time for perfect equipment or perfect procedures, I salute you for your time and troubles.

This helped tremendously. Thank you so much.

I just bought an old set up from my aging neighbor. this helped a lot. thanks

After watching this video and reading most of the comments, I fail to see where you went wrong. I think you explained your equipment and the "how to" process well. I've worked in a panel shop as an engineer and been around a many professional welders. I'm not a pro but in my opinion, you made a good video.

I hate to be negative, but I have also been in the trade for 33+ years and now teach it. I know you are approaching this from a "real life" perspective, but I can't see where it is advantageous to show defective equipment in need of repair and teach improper safety set-up. I think teaching the "industry accepted" methods is safer than just passing on our own experience. I do commend you for wanting to pass along your experience to people just starting out.

awesome video. thanks for the info

Helpful vid! Gauges are kind of like speedometers on cars - you should intuitively KNOW if you're going too fast! the speedo just confirms it. I'm a fan of check valves though - you never know when your neighbor is going to come by when you're not home, with an "emergency', borrow your torches, and set everything wrong ...

Hello and thank you for your video. I want to add my 2 cents, THANK YOU for showing exactly how you do it, your way, with your equipment. Not all of us can afford NEW equipment (or all new equipment) and some may do as I did and get things second hand, then invest in arrestors and study all the OSHA safety guidelines like O2 tank open all the way and 1/4 turn on Acetylene tank. You do not claim to be 'the source' for all knowledge on OxyAcet welding, and show people the defects of your equipment. This is a forum where anyone can post their videos and we the viewers need to exercise discretion whether to follow the advice of the film maker. But even after taking a class, and getting textbooks from the library i still needed the extra nudge which your (& others) videos helped a lot!

geez i've never even heard of flashback arrester on mine, thanks for heads up

in the case of Oxygen tanks, the valve actually needs to be opened all the way because of the higher amount of pressure present in the tank and the way the back-seating valve works. If it is not opened all the way apparently there is a risk of there being a leak in the threading of the valve itself.

Nice

We will probably always disagree on this. The difference is the approach we take to service and repair. There is room for both of us. I invite you to participate in the discussion and produce some videos of your own. Our audience is the better for differing opinions. Thanks for the comment. GFM

I'm new to oxy acetylene and have watched several videos. Although I learned a bit from this one I would strongly discourage newbies from cranking on a torch based on the information and set up shown here.

I got knowledge

Your videos are great and I love the way you handle trolls. Would you be willing to do a video showing how to charge a heat pump in the heating mode in cold ambient? How about a video on finding refrigeration circuit restrictions? I just pulled a txv that I'm pretty sure was sticking, but once out, it seemed to pass my blow in it test. The liquid dryer had more blowing resistance than the txv seemed to. My vacuum pump wasn't working so this job is tbc when my new pump comes in. When you retire, you should open a support line (during the hours of your choice) and charge younger techs for live support while they are in the field, walking them through stuff. Or sit home and get paid to talk on the phone now :)

Remember everyone!!....NEVER go higher than 15 psi on the Acetelene. Acetelene becomes VERY UNSTABLE at pressures higher than 15 psi!!...Open the Acetelene valve 1/4 to 1/2 turn...NO MORE...in case there's a problem, you can shut it off quickly. Open the oxygen valve slowly at first, then open it FULLY. ALWAYS open the oxygen valve FULLY bc if you don't, it could damage it. It has a special kind of valve on it that could deteriorate if you don't...👍😁

grayfurnaceman Oh, OK, So I can go as high as *40* Let me ask you this, my low pressure acetylene gauge is acting goofy, (I just got this set *used*, its one of the little baby sets) 1st the needle was under the peg, so I took the cover off and moved the needle. With the acetylene valve at the torch end closed, the gauge goes up to about 5 PSI But when you open the acetylene valve at the torch end, the gauge goes down to Zero. Turning the regulator in, with the valve open (at the torch end) has no effect on the reading. I did light the torch, and adjusted my flame, and it did seem to work OK, But of course I don't know what my true pressure is. Do you think is is (hopefully) just the gauge, or does it sound like the regulator is messed up?

I don't want to trash on your vid and say it's all wrong, but I've learned this way: Back out t-screws on both oxygen and acetylene until they're loose (flick it and it'll move) Make sure the valves on the torch are closed before pressurizing. Pressurize either first, but for acetylene, open the valve one full turn. Then tighten the t-screw until the acetylene is at 13 psi. For the oxygen, open the valve all the way. Pressurize it to 20 psi. Done! Now just open the acetylene valve on the torch a little bit, ignite it, adjust the flame, then add in oxygen. Easy.
