I'm a qualified technical educator but retired after decades working away from manufacturing engineering. I need to remind myself of the technology I learned as a young man while working in scientific instrument making. I found this video very clear, no waffle, an excellent explanation. After watching it I was left with valuable memories (and notes) of safely setting up and closing down an ox-acetylene kit which are superior to the those gleaned from the kit manufacturer's manual. Thanks very much.
Thank you very much. I am 50 years old and learned to use a torch when I was 17 or 18. Over the years I wondered if I was doing it right. I am not a professional by any means, just a guy that uses a torch once in a while. Everything you did in this video my dad taught me all those years ago. I just need to brush up on settings and metal thickness etc. Thanks again.
I was taught how to do this in 1967 by my metal shop teacher. You teach the procedures exactly the same as I was taught, fifty years ago. Way to go! Great video!
I have torches that are that are at least that old, and the gases haven't changed! It's Classical Technology! People might laugh at my torch outfit, but just yesterday at work there was some light welding or brazing to do, outside and maybe fifteen feet off the ground, and no electricity yet. OOps! So I practiced a little gas welding and "brazing", just in case.
Off all the oxy/acetylene videos I've watched on TH-cam yours was the most complete, especially the reasons why you do things. Definitely will get the guide you recommended. No other video mentioned that different metal thickness requires different tip sizes and different gas pressure. Thanks. Really good.
I learned to gas weld at the age of 10, not without the signs of my learning curve, my dads boot print on my A, literately, for forgetting one step or another, then shop in school, topped with my carrer and yet I'm lax on bleeding them down. No excuses, only reasons, are they aceptable, just because you survived yesterday, don't guaranty the same today! Nice Vid! Thanks for the reminder! Changing lax behavor, Keith
If we had youtube back in 1991 my high school metal shop teacher would've made this a mandatory video. So much safety stuff I've forgot over the years! Thanks for posting!
I have welded for over 20 years.12 of those years i was a union journeyman structural iron worker. More recently in a health care facility. You always give good tips and common sense, something not so common thees days Keep up the good work and Thank You.
A very well thought out video and I like the tips on safety and where to find more information. I cut just about everything with my powerplasma cutter but I suspect I will buy an oxy-fuel kit sometime soon because it is so useful
Aidan Wilson Keep in mind that with oxy-fuel, you can cut, weld, braze, heat, and probably more. With a plasma cutter you can really only cut and you need electricity and compressed air for it.
Jody, your videos have helped me become a much better tig welder. I owe you big. I'm now working as a professional tig welder, after 5 years as a mig/stick guy. Thank you!
Great job, was HD truck mechanic for 20 years and used torch almost daily. I got cancer and am just getting back into it after 20 year layoff. Yeah, I know LOL. Anyway, your video is the best refresher course I've seen, very professional and always appreciate referals to more good info e.g. Smith DVD/Audel reference manual. Thank you
The one problem you are having with cutting the 1/4" plate was too much Oxygen pressure. Seems you were set at about 40 psi and you could do the same cut with 20-22 psi. with that tip. You can tell you have too much O2 pressure by looking at the video of the cut. If you notice the slag is going straight down under the 1/4" material. That is an indication of too much pressure and will allow the slag to blow back behind the cut due to the high pressure area in the kerf and cause the steel to "weld" itself back together. If you notice on the 3/4" plate the slag coming out the bottom of the cut was at about a 45 deg angle toward the forward movement of your cut. Perfect! This is due to a balanced pressure with just enough to go through the steel and just enough pressure to create a low pressure front in the direction of travel to blow the slag out in front of the cut and not cause it to be sucked back into the kerf. With the exception of a dirty tip. 9 out of 10 problems of cutting is too much O2 pressure. With the proper tip you can go through 1" material with 25 psi O2 all day long.
Another great video, Jody. I had a friend who died beside one of those oxyacetylene tanks. It made me lots more careful when using my own torch. And, it makes me roll my eyes when I hear people brag about their decades of experience doing mechanics the sloppy way. Being careful is only a little more time consuming, and it sets an example for everybody else in the shop....
Good video,,, One thing to keep in mind for every welder, If you run that bottle dry, replace it!!! Acetylene bottles are weird They have acetone inside,,, I don't know the ins and out but looking at what an Acetylene generator can do,,, Safety is key,,,,.. Jodi, You're the bomb buddy,,, A lot of apprentice welders in southern Alberta, Canada respect the hell outta ya,,, Kuddos James
Your videos are so helpful. I learned oxy acetylene use in high school, when they used to teach it in the 70s. I remember the teacher stressing rbo for oxygen, as well as the ability to "emergency" shut off the acetylene. They also stressed the importance of never turning the Acetylene regulator beyond 10. Thank you for this very well done presentation. I have learned and been reminded of much from your videos. Thanks again.
Thanks for another great video Jody! I would add one more step to the shut-down procedure: after extinguishing the flame and shutting the supply valves on each of the cylinders, pause for 15-30 seconds to see if the regulator-hose-torch assembly holds the pressure reading on the high-pressure cylinder gauges. Any leak in the system will cause a fall in the high-end reading and should prompt investigation with soapy water to find the source of the leak before the equipment is used again. Thanks again for all you do for welder education!
On my first day of welding school the teacher taught the torch safety precudure. Fast forward 13 years later Im cracking the torch looking right at it with no safety glasses and guess what happens? The mother farting guage explodes and peppers my face with plastic spall. Needless to say my boss was pissed because I was the only shop welder and should have known better. So from that day on I made sure all the newer welders turned their heads when opening the torch. Remember, you can walk with a false leg, you can hear with a hearing aid....but you cant see with a glass eye!! So safety glasses all and I mean all the time. Sorry for the rant but I hope this helps. Safety First!
I've had splinters and little hooks in my eye from grinding before and had 'em dug out with the little needle and microscope at the clinic 3 times now and its no joke, once from blowing mud off excavators with a turbo nozzle left me blinking and eye watering for 4 days. Not fun, not worth it; now I wear the glasses. Gloves and glasses always, once burned now vigilant - Those guys that don't are either lucky or they haven't been there yet. There's no good in following the blind into ditches.
I was taught in school everything exactly. In 1968 At Jackson welding school in St Louis.Don Jackson was the welding Guru on the Arch project. He could do things that nobody else could do. His work was awesome. Keep up the good work.
I had learned to weld over 30 years ago at a friends' shop but I really needed this refresher video and you did a great job of jogging my memory and I will keep this video in case my old brain slips up. You know my old teacher was one of those guys that said don't purge the hose as I was wasting gas but even 30 yrs. ago I thought that was dangerous so you made it clear that it is and common sense says it would be. Thanks for this down to earth showing and hopefully it will save someone like me from committing a bad mistake. New Sub Here~!!
Jody, I am just a beginner and your video is the best so far. I learned more in a short period of time here than all the others combined. You also included a shutdown sequence that others skipped. Thanks.
Great video. Been soldering 40 years and MIG / TIG for 20, just bought a used gas rig so I'm trying not to go bang and your video is helping. Just wanted to thank you for the info on the "Welding Encyclopedia". Went to look for one and the editions around 15-20 1950 - 65 are going for $500 - $700. Found one I thought must have been a misprint on Amazon 1930 Seventh edition for $18. Arrived today. Very cool book. Ads in the back are priceless!
I really like all of these videos. I am by no means a pro welder. Just making maintenance repairs and light fab jobs. These videos have helped tremendously. I took 3 different welding classes in high school all involving oxy fuel cutting. Surprisingly our teacher never even mentioned any of this procedure. Basically I've been doing it wrong for years. Thanks for the great info.
@5:05 I finally found you after you're recommended by this Old Tony Channel! I want to thank you cuz I've been watching dozens of oxy-acetylene channels since I bought a small tote kit yesterday with an MC acetylene tank. You are the only one I watched the actually says you set the pressure according to what is recommended by the tip manufacturer. This is my belief totally as I'm going to believe they're Engineers rare than a cookie-cutter all-purpose setting for brazing, cutting, and Welding--HOGWASH! The number 2 welding tip and the number 2 cutting ttip with my ProStar 21508 kit I'm just going to run at the Victor 3 PSI minimum acetylene. The Radnon Victor 6-MFA-1 tip wants 8 PSI acetylene minimum: which I am scaredy pants so get up to but I better cuz the booklet that came with it says if I starve the tip it will cause it to get hot and the likelihood of flashbacks.
I was working as a fitter in the fab shop at the nuclear power plant near Glen Rose Texas, back in the 70s. One of the welders hung his hat on an oxg cylinder while eating lunch. After lunch, he put on his hat and stepped outside for a smoke. The hat flashed and left him with a permanent reverse chili bowl haircut and scars. It was found that seating stem on the gauge was leaking. Thanks for great videos.
I use a cutting torch quite often now, and not one of my co workers has taught safe practices when it comes to this. Which is why I did my research and glad I did! Thank you.
I first learned how to oxy-acetylene weld about 10 years ago, but nevertheless I like to watch a video like yours every so often to keep me fresh and to make sure I don't get complacent in my ways. great video, btw. thanks
thanks for the video! I never knew about opening the valve up slowly. I last used Oxygen Acetylene Torches at a Vocational School 29 yrs. ago. I once again learned something from your video....thanks again!
Tank you for safety information .I have been working with oxyacetylene to cut the metal for years,but never cared about points that you mentioned ,especially for user guide manual (I never knew that such thing existed). I thank you again
Great video contribution. Indeed one of the BEST instructional videos about Oxy-Acetylene torch usage viewed in last 5+ years on TH-cam, concise and to the point with sufficient details for most DIY guys and new welders. Thank you and my best regards. I hope you can add a few words about flashback arrestors and check valves in this or future videos, and explain where to install them (near the torch or next to the regulator or perhaps both ends, and why a particular location provides the best safety practice.) Thank you again and look forward to your future video postings. BTW: Regarding the torch turn OFF procedures, I agree that some OEM/posted procedures seem contradictory. My overall understanding has been to use the reverse sequence of lighting up the torch. So, the most common suggestion is to tun off the oxygen first and then the Acetylene. Allow the tip to cool off for 30-60 seconds (to reduce the possibility of re-ignition or flashbacks), turn off the main cylinder valves starting with Acetylene first, since it is quicker and it is the more volatile gas than oxygen, [also emphasizing that Oxygen is not really a flammable gas, but it is an oxidizing agent that helps the combustion process when there is a fuel present, where as Acetylene is an extremely volatile flammable gas), and finally bleed off the static pressure build up in the hoses using the torch valves (oxygen first), and finally close them to prevent torch valve internal oxidization due to atmospheric moisture. I look forward to your comments in this regard, since my main objective is to learn from professionals like you.
Just bought my first cutting torch. Never used one before. I found this the most understandable video so far. I'm very great full for your time spent explaining.
+R.L. HEARN He makes it look so easy. He has got to have one of the steadiest hands I've ever seen. I'm trying to get my plasma cutting with my power plasma cutter to be as smooth.
Jim Belkin ,place a strait pice stock along your place to be cut for a guide, than all u have to do,is manage your distance of neutral flame to material & speed of travel, u can tell if to slow, slag build up on the bottom of your cut,to fast, and world of hots will, will, blow back.
I use Propane for cutting, the recompression thing was new to me. But crank up the valves slowly anyways because I thought it would be easier on the regulator. I also know from experience how much I need to crank up the valves in the torch to get a nearly perfect flame before I light it, so I only need to fine tune the flame. Very informative and easy to comprehend even for germans like me. Thumbs up this guy!
Thanks, dude. I am becoming a welding tips & tricks junkie. I absolutely check you info out and put it to practical use. Yeah, I'm nervous about my upcoming test, but I got your info in my brain and feel waaay more confident, thanks again!
I appreciate your videos, you have a professional way of doing things and mention the important, key things to remember for very good reasons. Love your videos
Thanks for your excellent lesson, you are my best teacher. You know, I am going to use this stuff at the first time with my ocupation. At first i am so afraid of it, i don"t know how to use it. But now after watching your vdo i am very confident to deal with it. I wish you be happy all the time.
It's 2018, Jody you look so young!! I just got my oxy/actylene setup today and knew exactly where to come for the best info. I was right about that, learned so much in a short time. GREAT video!!!
I set my acetylene tank on fire from grinder sparks - as an apprentice - I'll tell you it scared the hell out of me. It was a small flame, but let me tell you I always double check my connections now. For the 20 seconds it takes, its worth the time in my opinion. I didn't set up the regs, I just assumed they were connected well.
Didn't read through all the comments for this, but I was curious if you practiced opening tanks with your hand off the valve. Not sure how to describe it, but a foreman of mine explained to me that you should always open tanks without your palm resting on the end of the tank incase the valve decided to let loose and blow your hand off. He explained that you always open tanks where you left a margin of error for the valve to come off. GREAT videos though ! love them
Thank you for making my every day life safer! I'm a farmer and I use oxy acetylene once or twice a week. You have great information! Thank you for sharing
Thank you for the videos. I've been a subscriber but not a welder for a little while. Next week we start brazing and understanding the school handouts is a lot easier thanks to this video.
Excellent review video, thx. For cutting thinner material like the 1/4" plate, I like to use a tip with only 4 pre-heat holes. Makes a nice clean cut. These 4 hole tips are recommended for clean or new metal cutting, whereas the typical 6 pre-heat hole tips are recommended for "general" purpose & scaly metals.
Thanks for making the video. I just inherited a cutting torch and knew nothing about safe handling other than I knew they could be dangerous. Been watching some great video's on Oxy Acetylene cutting/welding.
Fascinating! I was not aware of half of those things, procedure, start up, shut down sequence. Probably explains why my cuts are always so rough, I am trying to refine my cutting skills through a little bit of knowledge gained. Settings have always been a mystery to me.
Welding tips and trincks, los mejores videos !!!!!! Felicidades y gracias por compartir con nosotros todas sus experiencias en el campo de la sodadura.
I have been checking a few videos on how to do it properly and by far this is the best. Thank you for sharing your knowledge. I will try to do a few cuts today 👍👍👍
Thanks for the video. After watching I know now that I've been opening the Oxygen valve too quickly. Will slow it down from now on (and also look away). Thanks again.
Your video was the most informative of all. My skills are poor at cutting, to much heat and molten metal pooling or reattaching it's self. Did pick up a welders encyclopedia 1974,can't wait to try and practice more. Thanks .
Good info! If your flame gets longer and sizzles a bit when you hit the cutting lever you got good settings. If you hear a slight whoo whoo whoo when your cutting your speeds good
Thank you again for a great video! You are correct about confusion concerning the 'shut down' procedure. I have been to welding schools that teach shut down fuel first, and other that teach oxy first! They even have two 'poems' to help remember: "A (fuel) before O (oxy) is the BEST way to go" or O before A is the ONLY way. LOL! Thanks again!
Nice cuts, dude! I've also seen a video of a machine operated oxy-propane torch cutting some .3 meter or 1 foot carbon steel and had a really clean and beautiful bluish cut. I'd used plasma for cutting really complicated stuff, stainless steel or non-ferrous metals.
I love your videos. They are informative AND entertaining. Who said learning shouldn't be fun! Don't listen to that other guy, just keep doing what you are doing: sharing your experience and knowledge. I just Liked and subscribed. Rich
@7:35 They're actually instructors and schools I've watched on TH-cam, mostly furnace and HVAC guys, that wanted to mix the oxygen and acetylene just to avoid the soot. So they want to take a chance on building a bomb just to avoid what amounts to heavy cigar smoke for a second or two. You are the first one to explain it that you don't want mixed gas when lighting it because of a flashback. Most Americans oh, well at least all the ones like me, and those that preceded me such as World War II era Americans, do like to know "the why" of an explanation or order.
and a quick ps, i'm mostly cutting propane tanks for bbq/s and now trying ac freon tanks, they are very thin, maybe .060, cutting with a 000 tip, seems to cut very well with the settings high, but you are the go to guy, the book says 3-5 acetylene and 12 or so ox, but it doesn't seem to have enough power, what great vids, and the little personal notes show a great deal of character truly and example of the humble master
MARTIALCOMBATIVES are the propane tanks used? if they haven't been left out emty for awhile you might wanna be careful cutting into them the propane usually "seeps" into the metal of the tank and if you don't leave then with soap and water for a few months they can make a fire this is of course for one's that have only recently been emptied out
thanks for those tips ! i've started the oxy-acetylene cutting program at school yesterdya and I was really wondering why my cuts were shitty as hell.. seriously, I can't wait to try it back on monday morning !
Funny how this video is in my recommended literally right after I finish my first time using a torch.. I watched these safety videos a while back tho and still remembered the basic principles you taught.
No need to cut a straight cut without a straightedge as long as there are no obstructions in the path of the torch. But for practice totally freehand is ok. I like to use around a 1 inch pice of bar stock for a guide and a smoother cut. Rusty Steel demands more concentration and the smooth side of the bar stock gives me a big advantage especially on a 3 or 4 foot cut.
When I cut plate I clamp a length of 50mm angle on the plate and mark a line 12 or 15mm from the angle with soapstone, depending which side of the line I want to cut. I ride the shoulder of the torch on the edge of the angle giving me a consistent gap about 1/4" and a nice straight cut.
Interesting to see your shut down procedure. I was always told to shut down my torch in the opposite sequence as I started it, that being shut off the oxy and then the fuel. I've seen a lot of conversations about this for both methods. I'd really like to find out what is correct.
Thanks. Great video for reviewing the proper way to set-up, cut, and safely shutdown. I reference this video last night to help remind myself to run a torch. Read an old book, LOL
As a tie-in video to this one, how about one of your great tutorials on plasma cutting? I always seem to get too much slag (amongst other screw ups!) when using mine, and have been trying to figure out what I'm doing wrong.
Very Good, I see so many guys doing the fast crack and watch. Also another thing I was told not to do during my Apprenticeship that alot of people do alot is, turning on the acetylene with no gauge attached tosee if the bottle is full. I was told that the Acetylene can ignite out of the main valve stem. Is this correct? I have just always believed my teacher and check the bottle with a gauge attached, that way you can see how full it is too. Great video cheers
Even though this is an old video, it’s great to go back to as a review. Thanks for the hard work in developing these tutorials. Good stuff.

Excellent video. I bought an oxy/map torch from Home depot, I use it mainly for brazing small stuff. Keep the info coming. Im learning to weld!
I use a cutting torch quite often now, and not one of my co workers has taught safe practices when it comes to this. Which is why I did my research and glad I did! Thank you.
I first learned how to oxy-acetylene weld about 10 years ago, but nevertheless I like to watch a video like yours every so often to keep me fresh and to make sure I don't get complacent in my ways. great video, btw. thanks
thanks for the video!
I never knew about opening the valve up slowly.
I last used Oxygen Acetylene Torches at a Vocational School 29 yrs. ago.
I once again learned something from your video....thanks again!
You've potentially saved me from serious injury I did this wrong last week at my new welding job thanks for the video
Tank you for safety information .I have been working with oxyacetylene to cut the metal for years,but never cared about points that you mentioned ,especially for user guide manual (I never knew that such thing existed). I thank you again
Great video contribution. Indeed one of the BEST instructional videos about Oxy-Acetylene torch usage viewed in last 5+ years on TH-cam, concise and to the point with sufficient details for most DIY guys and new welders. Thank you and my best regards.
I hope you can add a few words about flashback arrestors and check valves in this or future videos, and explain where to install them (near the torch or next to the regulator or perhaps both ends, and why a particular location provides the best safety practice.)
Thank you again and look forward to your future video postings.
BTW: Regarding the torch turn OFF procedures, I agree that some OEM/posted procedures seem contradictory. My overall understanding has been to use the reverse sequence of lighting up the torch. So, the most common suggestion is to tun off the oxygen first and then the Acetylene. Allow the tip to cool off for 30-60 seconds (to reduce the possibility of re-ignition or flashbacks), turn off the main cylinder valves starting with Acetylene first, since it is quicker and it is the more volatile gas than oxygen, [also emphasizing that Oxygen is not really a flammable gas, but it is an oxidizing agent that helps the combustion process when there is a fuel present, where as Acetylene is an extremely volatile flammable gas), and finally bleed off the static pressure build up in the hoses using the torch valves (oxygen first), and finally close them to prevent torch valve internal oxidization due to atmospheric moisture. I look forward to your comments in this regard, since my main objective is to learn from professionals like you.
Just bought my first cutting torch. Never used one before. I found this the most understandable video so far. I'm very great full for your time spent explaining.
+R.L. HEARN He makes it look so easy. He has got to have one of the steadiest hands I've ever seen. I'm trying to get my plasma cutting with my power plasma cutter to be as smooth.
Jim Belkin ,place a strait pice stock along your place to be cut for a guide, than all u have to do,is manage your distance of neutral flame to material & speed of travel, u can tell if to slow, slag build up on the bottom of your cut,to fast, and world of hots will, will, blow back.
Jim Belkin He is steady. Your right. I just researched the video for a refresher.
I use Propane for cutting, the recompression thing was new to me.
But crank up the valves slowly anyways because I thought it would be easier on the regulator.
I also know from experience how much I need to crank up the valves in the torch to get a nearly perfect flame before I light it, so I only need to fine tune the flame.
Very informative and easy to comprehend even for germans like me.
Thumbs up this guy!
Thanks, dude. I am becoming a welding tips & tricks junkie. I absolutely check you info out and put it to practical use. Yeah, I'm nervous about my upcoming test, but I got your info in my brain and feel waaay more confident, thanks again!
I appreciate your videos, you have a professional way of doing things and mention the important, key things to remember for very good reasons. Love your videos
exactly! I love these videos - very helpful!
Thanks for your excellent lesson, you are my best teacher. You know, I am going to use this stuff at the first time with my ocupation. At first i am so afraid of it, i don"t know how to use it. But now after watching your vdo i am very confident to deal with it.
I wish you be happy all the time.
It's 2018, Jody you look so young!! I just got my oxy/actylene setup today and knew exactly where to come for the best info. I was right about that, learned so much in a short time. GREAT video!!!
I set my acetylene tank on fire from grinder sparks - as an apprentice - I'll tell you it scared the hell out of me. It was a small flame, but let me tell you I always double check my connections now. For the 20 seconds it takes, its worth the time in my opinion. I didn't set up the regs, I just assumed they were connected well.
Didn't read through all the comments for this, but I was curious if you practiced opening tanks with your hand off the valve. Not sure how to describe it, but a foreman of mine explained to me that you should always open tanks without your palm resting on the end of the tank incase the valve decided to let loose and blow your hand off. He explained that you always open tanks where you left a margin of error for the valve to come off.
GREAT videos though ! love them
Good information as always Jody. I have been gas cutting for decades and did not know that recompression fact on Oxygen.
Keep up the good videos. Doug
Thank you for making my every day life safer!
I'm a farmer and I use oxy acetylene once or twice a week. You have great information!
Thank you for sharing
Thank you for the videos. I've been a subscriber but not a welder for a little while. Next week we start brazing and understanding the school handouts is a lot easier thanks to this video.
Excellent review video, thx. For cutting thinner material like the 1/4" plate, I like to use a tip with only 4 pre-heat holes. Makes a nice clean cut. These 4 hole tips are recommended for clean or new metal cutting, whereas the typical 6 pre-heat hole tips are recommended for "general" purpose & scaly metals.
Thanks so much for sharing your tips and tricks on welding and cutting. I wish I had you as my teacher.
Thanks for making the video. I just inherited a cutting torch and knew nothing about safe handling other than I knew they could be dangerous. Been watching some great video's on Oxy Acetylene cutting/welding.
Glad I found your channel, I only use gas a few times a year but I had no idea how to start & shut down! Thanks
Fascinating! I was not aware of half of those things, procedure, start up, shut down sequence. Probably explains why my cuts are always so rough, I am trying to refine my cutting skills through a little bit of knowledge gained. Settings have always been a mystery to me.
Welding tips and trincks, los mejores videos !!!!!! Felicidades y gracias por compartir con nosotros todas sus experiencias en el campo de la sodadura.
I have been checking a few videos on how to do it properly and by far this is the best. Thank you for sharing your knowledge. I will try to do a few cuts today 👍👍👍
Thanks for the video. After watching I know now that I've been opening the Oxygen valve too quickly. Will slow it down from now on (and also look away). Thanks again.
I'm just starting out so I have yet to learn what I need to learn. But this was a great video. Very instructive. Thanks!
Your video was the most informative of all. My skills are poor at cutting, to much heat and molten metal pooling or reattaching it's self. Did pick up a welders encyclopedia 1974,can't wait to try and practice more. Thanks .
Beautiful kerf on those cuts.
You've got very steady hands.
Good info! If your flame gets longer and sizzles a bit when you hit the cutting lever you got good settings. If you hear a slight whoo whoo whoo when your cutting your speeds good
Thank you again for a great video! You are correct about confusion concerning the 'shut down' procedure. I have been to welding schools that teach shut down fuel first, and other that teach oxy first! They even have two 'poems' to help remember: "A (fuel) before O (oxy) is the BEST way to go" or O before A is the ONLY way. LOL! Thanks again!
I'm actually learning how to use these things soon at Tidewater Tech in Norfolk, VA. Love your videos!
It's so strange. This is only the second video I've seen that says fuel off first. Makes one wonder. Truly appreciate the video.
Peter Ford me too, I've always been told to turn oxygen off first
Nice cuts, dude! I've also seen a video of a machine operated oxy-propane torch cutting some .3 meter or 1 foot carbon steel and had a really clean and beautiful bluish cut. I'd used plasma for cutting really complicated stuff, stainless steel or non-ferrous metals.
Your an excellent teacher, Jody!
You're
I agree to use flashback arrestors with check valves
I love your videos. They are informative AND entertaining. Who said learning shouldn't be fun! Don't listen to that other guy, just keep doing what you are doing: sharing your experience and knowledge. I just Liked and subscribed.
Rich
Liked your footage, clear and straightforward. Good instruction tool.
Another great video. I learn something every time I watch one. Thank you
I learned a lot from the video, professionally done.
Excellent video. So necessary to keep up to date with safety.
Great video! I was especially looking for the shut-down sequence and you covered it in-depth!
interesting, I just got yelled at today by my boss for bleeding the gas out when I was done, he said " your wasting gas!" keep up the good work man
Thank you, old, but great video. I’ll be sure to follow all precautions next time I use the torch.
@7:35
They're actually instructors and schools I've watched on TH-cam, mostly furnace and HVAC guys, that wanted to mix the oxygen and acetylene just to avoid the soot. So they want to take a chance on building a bomb just to avoid what amounts to heavy cigar smoke for a second or two.
You are the first one to explain it that you don't want mixed gas when lighting it because of a flashback. Most Americans oh, well at least all the ones like me, and those that preceded me such as World War II era Americans, do like to know "the why" of an explanation or order.
Just got a Radnor airgas house brand torch made by victor. Shut down procedure in the book is close oxy valve on torch first, and then acetylene.
Great video. I particularly liked the clear explanations on the safety tips. Some other videos the guys just get it wrong. Thanks.
The welding teacher hammered the same thing in welding class and I've been doing it ever since.
"Little black paratroopers that get all over your face" Haha, never heard em described like that before. Awesome video!
and a quick ps,
i'm mostly cutting propane tanks for bbq/s and now trying ac freon tanks, they are very thin, maybe .060, cutting with a 000 tip, seems to cut very well with the settings high,
but you are the go to guy, the book says 3-5 acetylene and 12 or so ox, but it doesn't seem to have enough power,
what great vids, and the little personal notes show a great deal of character
truly and example of the humble master
MARTIALCOMBATIVES are the propane tanks used? if they haven't been left out emty for awhile you might wanna be careful cutting into them the propane usually "seeps" into the metal of the tank and if you don't leave then with soap and water for a few months they can make a fire this is of course for one's that have only recently been emptied out
yes, but take the valves out and soak them for a couple weeks rinse daily thanks for the info
Thank you for taking the time to make this video. Classy.
thanks for those tips !
i've started the oxy-acetylene cutting program at school yesterdya and I was really wondering why my cuts were shitty as hell..
seriously, I can't wait to try it back on monday morning !
Awsome! Awsome! Video thanks a ton for doing it. I enjoy all your videos, but this one by far is my favorite. Thanks again
Funny how this video is in my recommended literally right after I finish my first time using a torch.. I watched these safety videos a while back tho and still remembered the basic principles you taught.
No need to cut a straight cut without a straightedge as long as there are no obstructions in the path of the torch. But for practice totally freehand is ok. I like to use around a 1 inch pice of bar stock for a guide and a smoother cut. Rusty Steel demands more concentration and the smooth side of the bar stock gives me a big advantage especially on a 3 or 4 foot cut.
loaded w quality one liners and great tips..much needed reminders even for us pro-ams thanks a ton
When I cut plate I clamp a length of 50mm angle on the plate and mark a line 12 or 15mm from the angle with soapstone, depending which side of the line I want to cut. I ride the shoulder of the torch on the edge of the angle giving me a consistent gap about 1/4" and a nice straight cut.
Thank you . Your education has been invaluable.
Interesting to see your shut down procedure. I was always told to shut down my torch in the opposite sequence as I started it, that being shut off the oxy and then the fuel. I've seen a lot of conversations about this for both methods. I'd really like to find out what is correct.
The procedure in this video is correct. Its logical, and agrees with all training Ive had. Never heard anyone explain it the other direction.
Thanks. Great video for reviewing the proper way to set-up, cut, and safely shutdown. I reference this video last night to help remind myself to run a torch. Read an old book, LOL
Can we get some videos of you showing us some gas Welding and gas brazing???
thanks for posing this wonderful video
I'd like to show it to my son for his talent is in it
thanks again
As a tie-in video to this one, how about one of your great tutorials on plasma cutting?
I always seem to get too much slag (amongst other screw ups!) when using mine, and have been trying to figure out what I'm doing wrong.
Thanks for the video, would you be able to explain the difference between the fuels, is acetylene used for different metals?
Thanks.
The only good one on TH-cam
Thankyou so much for sharing your knowledge and wisdom, brother.
Excellent information! Thanks a lot, Jody! Love your informative videos!
Your videos are great and informative. Thanks.
I love this channel. So much good stuff!
Keep sharing your "WISDOM" that GOD has blessed you with
Thank you for all your wisdom.. You are extraordinary person.
I have a complete set of 1968 Encyclopedia Britannica, that I refer to quite regularly indeed. I trust them more than I do google
Very Good, I see so many guys doing the fast crack and watch. Also another thing I was told not to do during my Apprenticeship that alot of people do alot is, turning on the acetylene with no gauge attached tosee if the bottle is full. I was told that the Acetylene can ignite out of the main valve stem. Is this correct? I have just always believed my teacher and check the bottle with a gauge attached, that way you can see how full it is too. Great video cheers
Good job! Lots of useful information
