- This one covers the regulator operation and how to set the pressures.
This video is part of the heating and cooling series of training videos made to accompany my websites: www.graycoolingman.com and www.grayfurnaceman.com to pass on what I have learned in many years of service and repair. If you have suggestions or comments they are welcome.
If you are a homeowner looking to repair your own appliance, understand that the voltages can be lethal, the fuels are highly flammable and high pressures are used. Know your limits. - Jak na to + styl
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.
Whew, no flashback arrestor. Great video though! Remember, just because you've never had an accident doesn't mean it will never happen.
I'm an ironworker and for us through the apprenticeship we are taught to have acetylene from 5-7 ! And oxygen around 40.
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.
28 on my oxy, and 8 on my acetylene. Sometimes make my oxy a lil lower, that setting for me is what I like.. Damn good video. I can usually set my torches by feel these days..

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.
Thanks for the support.
GFM
Thank you I got Welding to school I really need to learn how to do this
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 ...
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.
hey gray for the record people really have no clue on most anything they watch on youtube and it makes them feel better to google something after watching a vid so they can watch it again and then reply with a jerkoff comment. fact is there are prolly 1000 other vids on this same topic and you got 70k subs and also 400000 plus views wich at the end of the day is why they are mad.. you are actually doing something while they are talking about doing something. id love to hang with you for a day and learn even a small fraction of the shit you know.
Greatly appreciate all of your videos
Thanks for the support.

YOU ARE CORRECT IT WAS A TYPO. I USE MY TORCH SET TO BRAZE COPPER LINE SETS WHEN INSTALL A/C UNITS. AND I NEVER GO OVER 5 POUNDS OPEN. AND JUST LIKE YOURS I DONT REALLY TRUST MY GAUGES. GOOD VIDEO AND THUMBS UP VERY INFORMITIVE.
Thanks this was Helpful I’ll give it a go myself now
good video, after 40 years of welding/ cutting as part of my business, I can relate to "I gotta replace those gauges"! Haha life happens, we don't always get to everything! Maybe I will now that I am retired and have the time. Gary
highwatercircutrider Don't count on the time. It may not be there.
GFM
highwatercircutrider teach people to use bad gauges and dont tell people not to stand in front of them and life may not get a chance to happen.
Thanks for the support. These things are pure fun for me. As you have seen, they are not professional quality.
GFM
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.
Thanks for the practical instructions.

4:52 - Don't mind me I'm just marking this cause I've given this video like 10 views cause I always forget my pressure. Now I can quickly reference this part of the video
This is the third time I have used you comment to get to the right part of the video. Time to use a sharpie on the gauges.
@@wittydisplayname1761 yeah, I just have a piece of scotch tape on the tanks with the proper pressure
Thanks again, have to brush up on stuff from trade and your a great teacher.
You're not your
I can't thank you enough for this video. The documentation that came with my Little Torch was so unhelpful. I've had this torch set for a while, but having no experience with torches and no proper instructions, I've been terrified to use it. I just walked through the entire process following your video and it worked perfectly! And, I now understand the theories behind all the dials and valves. Thank you, thank you!!! PS - for whatever it's worth, I thought it was kinda funny about your older gauges.
Thanks for the support. Sometimes when you use tools for years, you don't notice what bad shape they are in!

sorry to be off topic but does anyone know of a trick to get back into an instagram account..?
I stupidly forgot the login password. I appreciate any tricks you can offer me
@Dean Korbin instablaster :)
@Zander Bronson Thanks for your reply. I found the site through google and im waiting for the hacking stuff atm.
Takes quite some time so I will get back to you later when my account password hopefully is recovered.
@Zander Bronson It did the trick and I finally got access to my account again. Im so happy:D
Thank you so much you saved my ass !
Great video very helpful. .
Ah, you have to be patient but it is a very good explanation. Thanks!
awesome video. thanks for the info
Thank for the Videos.
very informative!
great videos.
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...👍😁
Thanks..: Greyfurnaceman I Liked the Video..
Even though I own a Henrob 2000.. I still found it helpful..
And the gauges added a touch of Steampunk class to it..

geez i've never even heard of flashback arrester on mine, thanks for heads up
Good Job
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!
Glad I could help.
GFM
Glad it made a difference.
GFM
God video learned a lot thanks.
great advice man thanx
Welcome
GFM
Hie excellent simply means if my regulator doesn't have that thing on top it won't work right
I was an oilfield welder for years and spent hundreds of hours on the end of a torch. I always ran my oxygen at 45 psi and acetylene at 15 psi!
That’s because you’re and igmo….
@@yamahajapan5351 I guess the English language may be a little to advanced for you! When you are trying to state that someone isn’t too smart, be sure you use proper grammar you dumbf! Correct grammar is --> “an igmo” NOT “and igmo”!!! It’s so damn funny when a fkn moron attempts to imply someone else is a dummy by using piss poor grammar and the entire wrong word!!!
@@trailerparkcryptoking5213 When correcting someone on their grammar, you should make sure that you get yours right *too*
That’s crazy. My whole life I’ve been taught having acetylene at 8 and oxy at 15. Never had an issue.
Can’t that explode
Wow, the flames looks very well
charming video, useful, thank you for explaining what you are doing and why. i felt like i was right with you XD
Nice
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.
Thanx
Thanks for watching.
GFM
Thank you Richard Elbe wondering if someone would say something about elaborating on setting pressure and also please replace those gages I've seen someone in my shop get seriously hurt when a gage exploded & the ones we were using at work did not look like anything was wrong with them the one in this video man they look sketchy as hell I was flinching everytime he flicked it with his finger LOL after what I have seen safety comes first
Thanks
Welcome
GFM
And I'm just curious how come my oxygen reg is red and my acetylene is red also they're both victor but the oxy one is a little newer I believe I also have a separate full size torch cart and one more regulator that's for my argon tank I purchased and these regulators are for my spare oxygen and acetylene tanks and hose I just need a spare torch I have my old Harris torch but I'm trying to find a collar for the tip to go on
More than they should. Gotta replace those gauges!
GFM
So I always set pressures higher by regulator and used the knobs on the tip to adjust. Taught like that in trade school and by co workers starting in the trade. In CAMT they taught me to use to regulator as a regulator and use the valves as valves. With your method, the valves on the wand are opened rather than tweaked or adjusted?
The valves are adjusted to limit the flow.
GFM
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 :)
acoustic4037 Good thoughts.
GFM
I would never work on the job for the equipment was in this bad of shape anyone that would is totally out of their mind OSHA would agree with me and send these people home in a minute
Pointing out faulty gear to newbies is not trolling. There was some good I formation but there is also a bit of do as i say not as i do and that can lead to someone getting hurt.
My torch head has a lot of carbon in it. It is OK to use carb or brake cleaner to get this out? It's an older torch from my late father. It was used and abused but still works quite well.
You can, but would follow up with water.
GFM
Is that an MC tank you got there on the Acetylene? What does the pressure read when you first get it exchanged with a full one.
I believe it is. I think its around 225#
GFM
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
thank you for video ,great help . what about micro torch
Why would you want one?
GFM
@@grayfurnaceman got one as a gift just wanted to try it out
@@grayfurnaceman got one as a gift ,just wanted to try it out.
I got knowledge
Never welded before, only looking to do small cutting and welding jobs. Do I need a gas or a electric welder? Thanks for any advice.
get a stick welder they are harder to learn but better outside and once you get the concept of how to use one its easy and not much to carry around.. mig's are expensive and need special shit to work outside when windy or pretty much anything other than in your shop.
Used propane and oxygen when I did iron work. Works just as good
About 30 years ago, I tried propane with oxygen. It did not work well. The oxygen use went up by around 4X. From a cost point of view, it makes no sense.
GFM
Yeah I agree with gray here...propane is alot worse to cut with and it's not even close.
Is the regulator no good if you get a reading above 15 (in the red zone) while the acetylene tank valve is closed, and doesn't go below 15 when opening the tank valve?
I would think the gauge is bad.
GFM
Although you didn't show it I'm assuming that the gas pressure jumps up a little because you turned off the gas at the torch, right?
Yes.
GFM
forget this video just follow the instructions that come with your torches
By the way sr.; I thaugt you were supposed to open the acetylene valva.all the way up since it also has a seal seat on top and in the
bottom .correct me if i am wrong i need all the help i can get have a.great day!
The Acetylene actually does not have a back seat valve. It uses packing to seal.
GFM
can this SAME hoses and regulators be used in a set up with propane(cheap!) instead of acetylene
Yes. You will need an adapter for the propane. You will use about 4 times as much oxygen. If you are using it for cutting, you will need a propane tip. Hope this helps.
GFM
Do I close the oxygen and acetylene and then release the pressure?? Or release the pressure and then close the oxygen and acetylene? I would really appreciate some help
Close the valves on the cylinders, then open the torch valves to release pressure, close torch valves then turn the regulator left until it is loose.
GFM
Someone gave me an old set of tanks with oxygen and a smaller one with acetylene. They are pressurized. Does that gas or oxygen go bad? Are they dangerous to use if they do go bad?
I have never seen it happen.
GFM
The gas inside doesn't go bad usually. Unless it was contaminated when it went in. The rock that the acetoline is disolved in will go bad eventually I think. However, The tanks themselves will be dangerous if they have not been stored correctly. Tanks need to be hydro tested every 10 years or so.
Thanx for the video , and ignore the negative comments , people's enjoy bitching for no reason some times
I when you use your torches just cracked the valves then then them fully back set the oxy and no more then 1/4 turn.
Do what?
A quarter turn open on the acetylene and open all the way on oxygen.
Those gauges have seen some decades of use.
Sorry I'm just trying to figure out how to adjust my regulator gauge so it's back at zero instead of zeroing out at the 50lbs mark or whatever it starts at but it's about halfway to the maximum of the gauge
If there is no pressure on the gauge, and it does not zero by that amount, the gauge must be replaced. No pipe dope.
GFM
OK, so about 5 on the gas and 10 on the O2. What about for cutting?
Someone one time told me about 5 and *30* for cutting.
Is 30 too high for the oxygen for cutting?
The pressure depends on the thickness of the steel to be cut. I usually use 40# for general cutting. Hope this helps.
GFM
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?
anthony diodati I would dump the gauge. It may have been damaged.
GFM
grayfurnaceman
OK< thanks, I'll try the gauge first. I really hope thats all it is. I gave $110.00 for the set up, then it needed a $8.00 fitting,
Then it needed new hoses, or the hoses repaired, as they were leaking at the regulator fittings.
But I got a new hose for free, so there was no loss there. But I don't want to have to keep putting money in this thing,
sometimes you try to save a nickle, and it costs you a dime.
Gauges should be set according to the manufacturer of the tip based on their recommendations and the size of the tip. Right?
That is not the way I have done it. For welding tips, I set the pressures more or less the same regardless of the tip size or manufacturer.
GFM
Thanks for your reply.. Do you care about the 1/7 discharge rule for acetylene? I am using a 60 Cubic Feet oxygen tank with a B size acetylene tank (40 Cubic Feet). At that size of acetylene tank the discharge rate should be no more than 5.7, right? A #2 tip set at 3 psi for acetylene will have a discharge rate of 5. No larger size tip should be used for this size tank.. Is that right? I am turning to you as the expert. Thanks.
I can't say whether your numbers are correct. I can say that I have used a C acetylene with a cutting torch that will Will cut 1" steel. Lots more than a #2 welding tip.
GFM
How to adjust the knobs on the excelling torch head video how to adjust the knobs on a settling torch head video
People say you're settings are wrong. For your specific setup they seem fine. But in an industry setup these settings will not work.
All great, except that the oxygen bottle should be opened all the way and 'seated' open to prevent leaks. That's how O2 valves are made to be used.
First, the oxygen cylinder is not a "bottle". A bottle contains a liquid not under pressure.
I was taught in the 1960s to backseat the oxygen valve. That changed in the 1970s. The valves were redesigned to allow them to be opened partway.
GFM
I'm holding my torch kit and heard the hissing in the video... omg I fkn panicked
Do I have to use oxygen to weld ?? O it can be done with just acetylene ??
There is an air-acetylene torch. It works for high temp brazing but is not hot enough for steel welding.
GFM
Mcb box se staplaijar embhotar koneksan
My oxygen keeps escaping still from the regulator????
Good video but please buy new regulator and gauges haha!!
pls change the gauge
+Fathma Sameer I have a video on changing the gauges and installing flashback arrestors.
GFM
over time I have noticed several fellow workers feel that more psi is better, yet they end up with leaks.
Very common. But it does not give better results. Usually worse.
GFM
Would it be same if you use propane
The procedure is the same. The settings are different as propane uses more oxygen than acetylene.
GFM
Please do not take my comments as "competing with you". I realize that it is difficult to say something in text and not have it taken the wrong way. Perhaps I should have said nothing. I don't think I would have the patience or knowledge to produce training videos such as yours, so for that I am commending you. Cheers!
Why not acetyline and oxygen readily mixed inside the cylinder?
Well, if you wanted a bomb that would explode when you light the torch, I guess that would work well.
Good grief think about it.
GFM
Wow ...try putting acetylene and oxygen in a garbage bag then adding a wick. Light the wick and see what happens. You will have your answer. Lmao good luck. We use to make these bombs all the time.
Acetylene pressure seems low, are you sure the gauge is not calibrated in bar
That's because I set acetylene to sensible (to me) pressure. Many set to 15+. I I consider that to be excessive and could be dangerous.
GFM
This equipment is dangerously old, oxy/ace lines should be replaced, every 6 years is standard but usually not needed, but 20 years is getting pretty suspect and a recent hand held unit with check valves is far safer than an older one may be. Not many ace explosions noted in news but they do happen on occasion. Be safe. (There was one last month, blew up windows in two houses after leaking tank on truck caught/exploded).
When you check the Oxygen level, do you have to turn off the Acetylene torch regulator?
No they are only connected in the torch.
GFM
How can anyone learn from you when your equipment is so run down (in need of repair).
+Tbvck I seldom see equipment that is up to standards unless it is new or in a classroom. Note I have referred to another video that covers the upgrading and repair of this torch set.
GFM
lol you don't own this shit or at least not a portable set if you did you'd know thats why hes making the vid.. so people see how shit is in the real world and how to use it when you get on a job with a guy who has old equip and he expects you not to whine and bitch like a princess with daddy's new equip you got use to.
My is acetylene is in the red on gage what could
If the adjustment does not change the pressure, the regulator has failed. Could be dangerous as high pressure in the line could cause spontaneous combustion and an explosion.
GFM
ah!
Where did this goose come from..???
