I welded for over 40 yrs. At one time I was certified in all processes and metals. I'm not trying to brag. Just saying I know what I'm talking about. This is an outstanding introduction video. I had a neighbor teenager who ask me to teach him how to weld. I had him watch this video first. Then I tested him on what he learned. Smart kid even brought notes. Set everything up from the beginning. Very good video.
Hey Mr. H, i was one of your students in metal class 2 years ago but i never had any interest in it and did not pay attention at all, which i now regret very much. I am now welding at work quite a lot and i am really enjoying it. I just bought a mig welder to have at home so i can keep practicing. Came across this video as i want to learn more about the different types of welding and instantly recognized the shop. Anyways just wanted to say i really wish i payed attention in your class cause you are a great teacher. Hope you are doing well during these times.
I completely forgot I was good at this back in highschool shop class, then again it was 35 years ago, so this was an awesome refresher video. Thanks for posting it.
Thanks so much for this video my friend. As someone that had only recently realized gas welding was even possible, your video was exactly the right pace of entry for me. You have a natural affinity for teaching. Appreciate your time!
Thanks for watching! updated video here with some PROPER information! I made some mistakes and fixed them in this video: th-cam.com/video/C6lluYIl9Xk/w-d-xo.html
I just started taking a welding course and your videos provide some extra info that is very helpful... will be checking out the rest of these. Thanks for sharing your knowledge with us!
Thank you. I'm a woodworker, but often need to do some metalwork. To save myself the delays and cost of outsourcing I learned to Mig & Tig, Braze and thought I should add acetylene to the skills. I very much appreciate your excellent tutorial. Many thanks
Oxy-Acetylene gives a very good base for other welding processes because it teaches puddle control at a much slower speed than MIG or stick. It also works well on light material if there is no MIG welder around. Thank you - I remember learning this in highschool. Bob the (retired) welder/fitter.
My neighbor who has taught welding at a Iowa State suggested I learn this method because it will teach me puddle control and the rest will be become easy. He’s going to give me lessons on Sunday afternoons.
Thanks for this. I’m just getting started - home schooled - with MAP/oxy, and it doesn’t look like I’m too far from what you have, here. Keep up the useful videos.
check out the updated video. Has some "proper" safety instruction in regards to tank setup and shutdown. I made a few mistakes and corrected them here :) Thanks for watching th-cam.com/video/C6lluYIl9Xk/w-d-xo.html
Burninating love it. All hail Trogdor. Honestly though thanks for this one. I just learned to Braze with a small oxy acetylene set up. This seems like the next logical step.
Amazing video, I’m in welding shop in school and I can’t tell you how many times me and some other people have to alert people that what they’re doing is dangerous, I will have to suggest this to my shop teacher so they can watch it and understand what they’re doing
I've updated a few things since making this video as I had a few bad habits. New video up with more info and some extra safety stuff. Thanks for watching
Literally 6 hours away from gas welding and I needed a technique, technique helped me get stick welding down and mig I just didn’t have a technique thanks man!

I work in hvac and use assetaline a lot for brazing refrigerant tubing and somehow it never occurred to me I can use my torch for welding. Thank you so much for the videos! I now have a lot of home projects I'm doing
welding with ox-acctle is old school it uses a different filler rod than brazing rod. it is quiet and requires no electricity, takes lot of practice. It is the best way to learn heat controll, running a puddle and getting proper penetration. If you can ox-acctelene weld, Arc and stick will be very easy to learn.
Thank you for posting this video, it was very well put together. Also, you are one hell of a teacher! The whole time watching this video I kept saying to myself "man, this guy is so detailed in his explanations/instructions, giving good points of reference so anyone can know that they are doing the steps right, and will know what to look for themself" - I then scrolled down to the video description and saw "video for my high school students," duh, your an actual teacher lol. Great job boss, this is going to help me learn how to start welding, and I'll be picking up a Oxy-Acetelyne welding kit in the next few days.
Thanks! While I do my best this video has some safety mistakes so I would recommend this one that goes into more depth and fixes some bad habits I had when filming this current video. Check it out! th-cam.com/video/C6lluYIl9Xk/w-d-xo.html
I just inherited an oxy-acetylene setup, full sized tanks. This is incredibly helpful. When I got the call to pick it up my first thought was, "neat, a new way to blow myself up." But as a Jeeper welding would be incredibly handy to know. Thanks for your video, I'll be checking out the others.
Watch my latest video on welding. Much "better" information than this one! I keep learning and changing up how I do things as I keep learning and improving myself 😀
Use the torch for cutting. Use a stick welder for outdoor use as the coating provides the shielding gas. There is a function in the metal called the HAZ (heat affected zone). the slow action of the torch gives a very wide HAZ which changes the metallurgical characteristics of the metal you're welding. Not what you want at all. For cutting, get a spot red hot, then hit the "turbo" button for a big increase in O2. This will punch a hole in the work and you can keep the cut moving. It works OK, looks not so good compared to a plasma cutter. Stick for outdoors and on "rough" work (6010 stick I think). MIG for indoors and TIG for true precision work with minimal HAZ. I've been told that TIG is hardest to learn, but to learn it first. After that, you'll be a wiz at the other two. Some say "MIG like TIG" is the ultimate compliment for a good quality MIG weldment.
@@burnerjack01 I have found that teaching the kids the techniques of working the puddle is my requirement before I teach them TIG. Stops them breaking everything. We do mostly Mig welding in class as our stick welder has been busted for awhile and I'm waiting on some more budget to get it fixed :) Thanks for watching
Great video! This is the best tutorial video I have found! I'm glad that you didn't adjust PSI on the tank while the welding is live unlikely another video.
Currently in this metal class at seaquam. Unfortunately mr hamade has taken over and everything is too much by the book and there is no learn by mistake and have fun (but be safe) like your classes are. I will alwayse remember you as the best teacher !!
I still remember when u was in grade 8 I was using the grinder without safety glasses and you tapped me on the shoulder and all you said is “ do you like your eyes buddy?” And walked away😂 I was like “darn I think I do”. Simple phrases like this help me alwayse remember the safety !
awesome vid man, and I appreciate that you know how to use your camera quite well so we can actually see what youre doing. watched a number of vids before this that were just straight light the whole time
Thanks. It was tough getting the right settings. I think i could improve it and not damage my camera if i put some welding glass in front of the lens to get some better detail in the molten flame and weld
@@WeBuildStuff Yeah I can only imagine, must be a solid camera. Hey while I have your attention, if you ever mess around with colorful welds Id love to see you do a video on them and Im sure others would agree. youre great at explaining stuff

Im really enjoying it and watching the basics on here has been great. Thanks for the content, ill be watching more of it for sure.

Also, NEVER lay a Acetylene tank on its side. Something about the acetylene coming out of the matrix inside the tank, making it unstable and dangerous. Dunno, just what I've been taught.
john hanrahan hey thanks for the tip! I’m starting to get into welding and really want to know more about the subject. Hence why I’m here lol. Any advice is much appreciated!
We were taught back in aircraft maintenance school when you make your pool, make "smiley's" and push the bead slowly, rocking back and forth till you get to the end.
I was just sitting here bored thinking about dumb stuff and thought "I wonder if its possible to weld with a oxy torch" sure enough you can. Very cool. Im gunna buy that tip and try this out myself
check out my other long oxy-a video. It's got some better advice for setup and shutdown. I made some mistakes in this part 1 Thanks for watching! :) th-cam.com/video/C6lluYIl9Xk/w-d-xo.html
It was quite a few years ago that we purchased this specific one shown in the video for the school. I think it was similar to this: www.kmstools.com/victor-medalist-250-medium-duty-welding-cutting-outfit.html
It isn't as strong and I rarely do it but it is part of the skill building I put students through so they understand the basics and how to handle a torch first.
@@GuapDolo if all you have is oxy acetylene then yes you can weld exhaust pipe. It can be slower and more costly than a quick arc or mjg weld but all can do the job
This is the most informative and best organized video i have seen! Question? What is the best type of welding to repair a broken wrought iron railing welld joint?
Manufacturers Victor and Harris both recommend shutting oxygen off first. Carbon can be thrown back into the torch if the acetylene is shut off first. Like most old school rules of thumb, they are not based on science, but rather opinion. People who assume the acetylene is more dangerous then the pure oxygen are "playing with fire". Always do what the manufacturer says, rather then what someone tells you. Even an instructor, who may have picked up their own bad habits, tells you something.
I agree with what the manufacturers say and we are doing it the way that many high schools do in BC based on how many of us tech teachers were trained at BCIT. I will probably switch things up though since so many people have said the same as you!
Can I add to the previous comment that when shutting down a torch either in a controlled fashion or in an emergency due to a flashback the reason turning off the oxygen first is recommended by manufacturers and industry bodies is due to the need for a consistent response by the operator in emergencies (don’t think just act) and because the oxygen is significantly more dangerous. Yes, the acetylene is fuel but so is the torch and hoses as far as the oxygen is concerned, turning off the acetylene first in a flashback won’t stop the hoses burning in a pure oxygen environment. Turning off the oxygen first stops the risk of the flashback escalating.
Thank you. And as a part of teaching I am always trying to improve myself. Here is a better video with some updated information and better procedures: th-cam.com/video/C6lluYIl9Xk/w-d-xo.html Thank you for watching.
Please show technique doing LAP joints without filler rod. Explain which metal should be heated first. Dropping the camera exposure is an EXCELLENT idea; could you do that more often?
I used a torch to braze copper tube for air conditioning. If you light that torch inside a home without a little acetylene flowing, you’ll be cleaning that soot off the walls and ceiling
With all do respect i took 2 welding corsés one 14 months welding and lay out and 1 for pipe welding with torch cutting off the pipe in bevel, and the standard oxígas presumes are 15 psi fuel and 45 psi oxígen! Just my opinion
That's in my 2nd video. This video was to show just a fusion technique so my students can practice with two hands on the torch to get used to the process before worrying about stronget welds. Baby steps!
Tell him this is the updated video here: th-cam.com/video/C6lluYIl9Xk/w-d-xo.htmlsi=UX7M47Q36gLaegPM Has some better information based on our current industry standards. Thanks for watching!
I think acetylene welding is becoming a lost art. My father taught me to weld with a torch 50 years ago. When I ask some of the younger mechanics if they can weld with a torch, they'll invariably say, "What, you mean braze?" One bright spark actually told me you can't weld with a torch. "That's not welding, you're just melting two pieces of metal together," he argued. No one I know under the age of fifty can actully conceive of such a thing.
I'm a diesel mechanic in tech school and this was the first type of welding we were taught! I'm still a little green on it so that's why I'm touching up on this video!
I'm actually here because I am familiar with arc welding, but I was curious how the greatest generation welded the battle ships together than won WW2. I'd like to get a torch but the gasses are difficult to find in my area.
My welding instructor always taught me "Fuel First" Quarter turn, Oxygen half a turn to get started and then you can adjust it to what you need from there.
I'm a beginner and bought bottles, cables and the torches. But I'm WAY insecure about "assembling" the cables to the bottels and "clocks" as we call them. Im not sure how to use the washers (plastic, and metal). So for the time being, I cant use my kit.
Could you also feed mig wire in by hand while using the torch? 😅 Just curious if that is possible. Ive only ever mig and stick welded actually had no idea you could weld with OXY/Acetalyn till today
I was always taught this way as a safety precaution. Turning off the acetylene first shuts the flame off quickly if an accident occurs as opposed to shutting off oxygen first the torch flame remains burning with the fuel (acetylene). Some manufacturers have different recommendations but as a shop teacher in British Columbia we all try to follow a similar system. Work Safe BC and our BC tech ed organization have a safety guide called "heads up for safety" that is a great introduction on safety to almost every tool we use in high school shops. This helps with consistency throughout the province.
@@WeBuildStuff Just want to touch on the subject, manufacturers that say O before A recommend it as a safety test. Turning oxygen off first will allow you to check for any leaks in your valves. If your Oxygen is not completely shut off/there is a leak it will be noticeable in the flame. When you turn the Acetylene off the flame should die out completely, if a small flame is left then you again know there is a leak.
I used to turn the oxygen off before acetylene, that way I was sure both were off. There was always a tendency to forget to turn it off (oxygen ) if you turned the acetylene first. Brilliant tutorial, I can smell the carbon😁😁
Hi, I wanted to ask the shutdown procedure ... I read and saw inverse or equal procedures to yours (turn off before oxygen or turn off before acetylene), some say that it is safer in one way others swear the opposite ... question: which Is it technically the correct procedure in terms of safety? Does this also apply to oxygen/propane mixtures? Thank you very much!
I made an updated video addressing this. I now shut down oxygen first and acetylene second. I was taught incorrectly years ago and developed a bad habit The only time I turn off acetylene first is if I needed the flame out immediately. It usually will create a poppin sound and unfortunately cause some sooty build up in the tip. Updated video: th-cam.com/video/C6lluYIl9Xk/w-d-xo.html
@@WeBuildStuff No, you were taught correctly. A before O is correct for turning off your torch. less critical when you turn it on. the detailed reasons are on a separate post with today's date

I've done plenty of copper to copper brazing and copper to brass with flux but never steel to steel with oxy acet. Thanks.
We were taught back in aircraft maintenance school when you make your pool, make "smiley's" and push the bead slowly, rocking back and forth till you get to the end.
Yes always so many different ways to get the welds. I sometimes do circles, zig zags or arcs like the smileys. Thanks for watching
I was just sitting here bored thinking about dumb stuff and thought "I wonder if its possible to weld with a oxy torch" sure enough you can. Very cool. Im gunna buy that tip and try this out myself
check out my other long oxy-a video. It's got some better advice for setup and shutdown. I made some mistakes in this part 1
Thanks for watching! :)

The "sparks" are a good indication of penetration. Once you start sparking, keep the puddle going so the sparks keep flying.
Ooo ya! I should have slowed down and got it deeper for this video
I wish you are my teacher..i love the way you go straight to the point.
thanks!
What brand of welding equipment and model? I do like your torch for welding. Thank you.
It was quite a few years ago that we purchased this specific one shown in the video for the school. I think it was similar to this:

A before O or up you go. That's freaking awesome!
First part of my gas welding class at the British Columbia Institute of Technology!
Wrong
"You can get close without feeling any heat-
But I'm not gonna do that"
Ahem, are you trying to send me to the ER?!
I am not responsible for idiots that touch flames. Don't be an idiot ;)
Thank you so much sir this is really a very amazing and helpful video for the youths to get practical knowledge about oxy acetelyene welding.🙂👍
I’ve got some really nice penetration and no pops with a nice ripple pattern thanks 🙏
That's the goal! I need to do some more videos with better examples. I've improved a lot myself since filming this. Thanks for watching!
Learned how to gas weld like this in high school, the best welds never broke on the weld, they bent like a continuous piece of steel/iron would bend
Now I can confidently correct where I went wrong. Thanks.
Check the update video for a few things I did wrong too😁 thanks for watching

Great Job....i´ve been looking for this explanation all day long, and after a bucnh of videos this is by far the best, thanks!!!!
Check out my updated one with some better setup and safety tips!

You are the Bob Ross of welding 😎
Great video, well explained,, i never knew you could weld with out a filler rod
It isn't as strong and I rarely do it but it is part of the skill building I put students through so they understand the basics and how to handle a torch first.
Me, either.
Can you do this with exhaust pipe?
@@GuapDolo if all you have is oxy acetylene then yes you can weld exhaust pipe. It can be slower and more costly than a quick arc or mjg weld but all can do the job
Dig the Trogdor reference. Haven't seen him in a while!
Awesome video, thank you very much for doing this. 10/10
I don’t know but the zigzag looks like it made a cleaner weld awesome video very helpful
Thanks for watching!
Bro was that a homestar runner clip!?
@@GodsSoberGopher good jorb noticing that
This is the most informative and best organized video i have seen! Question? What is the best type of welding to repair a broken wrought iron railing welld
joint?
Any type of welder that can do steel! Mig or stick/arc is handy and strong!
@@WeBuildStuff Many thanks for your considerate reply!
"A" before "O" best reminder thank you sir
and reverse the process during shutdown :) I forgot to add that to this video
Manufacturers Victor and Harris both recommend shutting oxygen off first. Carbon can be thrown back into the torch if the acetylene is shut off first. Like most old school rules of thumb, they are not based on science, but rather opinion. People who assume the acetylene is more dangerous then the pure oxygen are "playing with fire". Always do what the manufacturer says, rather then what someone tells you. Even an instructor, who may have picked up their own bad habits, tells you something.
I agree with what the manufacturers say and we are doing it the way that many high schools do in BC based on how many of us tech teachers were trained at BCIT. I will probably switch things up though since so many people have said the same as you!
Can I add to the previous comment that when shutting down a torch either in a controlled fashion or in an emergency due to a flashback the reason turning off the oxygen first is recommended by manufacturers and industry bodies is due to the need for a consistent response by the operator in emergencies (don’t think just act) and because the oxygen is significantly more dangerous. Yes, the acetylene is fuel but so is the torch and hoses as far as the oxygen is concerned, turning off the acetylene first in a flashback won’t stop the hoses burning in a pure oxygen environment. Turning off the oxygen first stops the risk of the flashback escalating.
You are very good at teaching
Thank you. And as a part of teaching I am always trying to improve myself. Here is a better video with some updated information and better procedures:

Thank you for watching.
I was already sold on this video and then Trodgor made an appearance.
Consumate V!!
Tanks for the useful information!
Please show technique doing LAP joints without filler rod. Explain which metal should be heated first. Dropping the camera exposure is an EXCELLENT idea; could you do that more often?
Can you fusion weld cast aluminum like that?
Very nice demo, thank you.
I used a torch to braze copper tube for air conditioning. If you light that torch inside a home without a little acetylene flowing, you’ll be cleaning that soot off the walls and ceiling
We always have our welding ventilation going when the class is running. I turned it down for the talking parts of the video
With all do respect i took 2 welding corsés one 14 months welding and lay out and 1 for pipe welding with torch cutting off the pipe in bevel, and the standard oxígas presumes are 15 psi fuel and 45 psi oxígen! Just my opinion
that fuel is not acetylene but probably propane. NEVER use 15psi of acetylene
Just wondering why you didn't use filler rod
That's in my 2nd video. This video was to show just a fusion technique so my students can practice with two hands on the torch to get used to the process before worrying about stronget welds. Baby steps!
Great video Sir
I've learnt a lot
Thanks much
Our professor suggested this video to us .... because we have this in our physics workshop skills
Tell him this is the updated video here: th-cam.com/video/C6lluYIl9Xk/w-d-xo.htmlsi=UX7M47Q36gLaegPM
Has some better information based on our current industry standards.
Thanks for watching!
I think acetylene welding is becoming a lost art. My father taught me to weld with a torch 50 years ago. When I ask some of the younger mechanics if they can weld with a torch, they'll invariably say, "What, you mean braze?" One bright spark actually told me you can't weld with a torch. "That's not welding, you're just melting two pieces of metal together," he argued. No one I know under the age of fifty can actully conceive of such a thing.
I'm a diesel mechanic in tech school and this was the first type of welding we were taught! I'm still a little green on it so that's why I'm touching up on this video!
I'm actually here because I am familiar with arc welding, but I was curious how the greatest generation welded the battle ships together than won WW2. I'd like to get a torch but the gasses are difficult to find in my area.
@@JamesKelly89 since arc welding was invented in 1881 and patented in 1887, they probably used arc welders.
My welding instructor always taught me "Fuel First" Quarter turn, Oxygen half a turn to get started and then you can adjust it to what you need from there.
Are you referring to the cylinder tank valve or the torch valves?
@@WeBuildStuff Torch Valves
@@nathanmattera3393 cool. If that works for you do that. For my torches if I open a 1/4 it ends up being WAY too much gas at once
One thing to know is that an acetylene tank can only flow 1/7 of the tank per hour. That means a little tank can't run a big tip.
Can you only do fusion welds with oxy-A or can you introduce filler materials?
Which is stronger, stick or this?
I'm a beginner and bought bottles, cables and the torches. But I'm WAY insecure about "assembling" the cables to the bottels and "clocks" as we call them. Im not sure how to use the washers (plastic, and metal). So for the time being, I cant use my kit.
Damn, motion tracking bear eyes? Quality editing for a high school vid.
I get stupid ideas while editing sometimes... 🙃
I did this for the first time today and the lap joint hard
Can't you use "filler" metal? Like, a steel wire/rod?
Yes that is in part 2! I need to make a part 3 with better welds than I did in this video as well!
Could you also feed mig wire in by hand while using the torch? 😅 Just curious if that is possible. Ive only ever mig and stick welded actually had no idea you could weld with OXY/Acetalyn till today
Great vid. Thanks for making. 🙂
Thanks for watching!
What size tip are you using.
What size tips for different metals and thickneses
Estou gostando muito dos seus vídeos, dando like em todos.
Great video!
can someone tell me why does he closes the acetylene valve first?
I was always taught this way as a safety precaution. Turning off the acetylene first shuts the flame off quickly if an accident occurs as opposed to shutting off oxygen first the torch flame remains burning with the fuel (acetylene).
Some manufacturers have different recommendations but as a shop teacher in British Columbia we all try to follow a similar system.
Work Safe BC and our BC tech ed organization have a safety guide called "heads up for safety" that is a great introduction on safety to almost every tool we use in high school shops. This helps with consistency throughout the province.
@@WeBuildStuff Just want to touch on the subject, manufacturers that say O before A recommend it as a safety test. Turning oxygen off first will allow you to check for any leaks in your valves. If your Oxygen is not completely shut off/there is a leak it will be noticeable in the flame. When you turn the Acetylene off the flame should die out completely, if a small flame is left then you again know there is a leak.
@@StopKillerBear good tip. I do my own safety checks weekly in the shop but for students I find this method works well :)
I used to turn the oxygen off before acetylene, that way I was sure both were off. There was always a tendency to forget to turn it off (oxygen ) if you turned the acetylene first. Brilliant tutorial, I can smell the carbon😁😁
Hi, I wanted to ask the shutdown procedure ... I read and saw inverse or equal procedures to yours (turn off before oxygen or turn off before acetylene), some say that it is safer in one way others swear the opposite ... question: which Is it technically the correct procedure in terms of safety? Does this also apply to oxygen/propane mixtures? Thank you very much!
I made an updated video addressing this.
I now shut down oxygen first and acetylene second. I was taught incorrectly years ago and developed a bad habit
The only time I turn off acetylene first is if I needed the flame out immediately. It usually will create a poppin sound and unfortunately cause some sooty build up in the tip.

Thank you very much for your reply, it is a subject where there is still confusion.
@@WeBuildStuff No, you were taught correctly. A before O is correct for turning off your torch. less critical when you turn it on. the detailed reasons are on a separate post with today's date
Very helpful. Thanks!
