[@snymat_68]

That's my understanding as well. A double-seated valve. To touch on another of his comments, it's fine to lay down an acetylene tank. You just have to leave it vertical for a while before using it to give the liquid a chance to settle back to the bottom of the porous substance the tank is filled with.

[@MasterHustler]

You are correct. I work in oil and gas and that is industry training.

[@andrewalexander9492]

@@snymat_68 Yep, there's nothing inherently dangerous about transporting an acetylene cylinder on it's side (and arguably it's safer, if you don't have a good way of securing it upright) But like you say, you do have to let the acetone settle back into the porous material before using, or you might be feeding liquid acetone into your torch.

When I was a junior in high school in 1969, my shop teacher taught us how to light a torch and make a neutral flame with it. He also taught us a carburizing flame, an oxidizing flame and how to cut with a cutting torch and how to braze with a torch also. And he made us do each one too, multiple times. At sixty eight years old I still use these skills, Thanks Mr Odson, I didn’t realize what you were teaching us that week would be so useful for so long!

[@dannywilsher4165]

I worked in the oil fields welding right after I graduated in 73. Bought me a gas powered 300 amp machine and jumped in with both feet. I eventually wound up in Odessa Texas building new drilling rigs. Money was flowing freely in those boom times. I tell this to say that I learned to use a cutting torch with some of the best in the welding business. They would do all kinds of tricks to show off their skills. One was to strip a welding rod of the flux and see how far they could cut it without burning or melting it in two. They usually used a 5/16 rod and very few could get more than an inch or more cut before they would fail. I always thought I could do anything bigger and better than anyone else so I started practising this technique. I eventually got it figured out to where I could cut an 1/8 inch rod all the way to the end with the rod standing straight up in my vise. The flame had to be set perfect, the oxygen pressure had to be perfect and I would us the rod and my hand as a fixture to hold the torch and come down the rod at just the right speed and the rod would roll over on both sides. I made money on betting many times doing this trick. Another thing is I never bought a tip bigger than a triple 0. (000) . I could cut plate 1 inch thick with a triple 0 and make it look like I was using a cut-a-line. Using a cutting torch is like anything else, with practise and trial and error, a person can acquire skills that are incredible. Thanks Mr Scott for posting another awesome video!!!!!

[@44R0Ndin]

Sounds like you made that cutting torch act more like a laser! That's impressive, I hope that you aren't still working in the oil fields (since '73 might as well be '70, and that would make it 50 years ago), and that you have at least tried to teach your skills to some willing apprentices. What I'm trying to say is someone with your skills would surely know so many little tips and tricks that you would make a good teacher, provided that you had students willing to learn (a thing sorely lacking these days, where school is thought of as a thing to be endured more than a thing to enjoy).

I learned how to use the hot wrench in grade 10, I bet that does not happen these days. At my high school one day the guys delivering the tanks let an O2 tank fall over, it went right through the cement block wall in the welding shop and into the quad. Thankfully it was on a weekend when no one was at the school, and no one was hurt, but it sure made a mess. I don't have one in my shop here in Tokyo, I have an air plasma cutter the lease on the tanks here is stupid expensive, the air plasma cutter is cheaper for me to run. I wish I could afford to have a hot wrench in the shop as they certainly do some things that the air plasma cutter cannot. Cheers from Tokyo! Stu

That is a truly lovely 10 minute summary of how to use a cutting torch - awesome work. I worked with an old german welder and he made cuts that looked like they had been done on a bridgeport. He had two tricks: he cleaned the holes with a number drill before starting and he made a copper bar with a step to rest the torch on and then adjusted the torch so that the flame was as you describe. As you point out welding is about watching the pool and moving when you see it is right.

[@ieaEH]

I would recommend when using the older torches without flashback arrestors to add a set, use at least a shade 5 to protect your eyes and open the oxygen valve all the way you are grown ups so it's up to you great channel keep up the good work.

[@dewidubbs6715]

Cannot stress this enough, if your valves do not have arrestors built in, buy more. Mount them between your hose and your regulator. Do not mount them on your torch unless you already have them on the regulator. If the flame burns back into your tip or you burn your hose the flame will shoot down your line towards your tanks. You will hear, smell, and possibly even see this happen. Quickly turn off your bottle. Your line will need to be replaced, do not mess with a damaged hose.

It's not the brightness of an electric arc that blinds you, it's the fact that the high temperature of the plasma in that arc means that it emits a lot of ultraviolet light, meaning that arc eye is just a particularly bad case of snow blindness. Treatment is the same for both, as are the symptoms. On the other hand, the flame in an oxygen/acetylene welding or cutting torch does not reach a high enough temperature to emit a large amount of UV, so the worst you'll get from it is the same you'd get from staring at an incandescent lamp, namely some spots in your eyes that will go away within like 5 minutes tops if your eyes were functioning properly before you started.

Great advice I had to relearn a couple years ago. Back in my oilfield days they was hardly a day went by I didn't have a torch in my hands. But I had been away from one for a few years. Then two years ago I got tired of grinding my cuts so I leased a set of tanks and bought a cutting and welding set to go with my Hobart welder. So anyway let's just say I was really rusty for a while. Then I begin to remember things and before Iong i was back to using it as well as I use to. Oxy Acetylene is a great tool but can be temperamental. You have to adjust it for what it is your doing. Also those adjustments are different with a rosebud or a brazing tip.

[@janderson8401]

A friend of mine worked for a boiler repair company. One day he was using the torch in the basement of a building. I know his tanks were mounted in the truck and I think there was a reel that let him unspool the length of hoses needed to reach the work. As he was cutting he felt a tug on the hoses. A few seconds later the torch was ripped out of his hands. He ran outside and saw his truck going down the street dragging a hundred feet of hose and a still burning torch.

One safety thing on the oxygen - it should be turned all the way open. It has a double seated valve and has a anti leak seal when completely open (and closed of course).

One safety tip I was taught is never to carry a bottle on your shoulder. If you trip and fall you are putting your head between the concrete of the shop floor and the heavy tank coming down.

[@dewidubbs6715]

Nothing you do should put the bottle horizontal. If your fuel bottle is sideways make sure to stand it up for at least as long as it has been laying. Acetylene is liquid in the bottle saturated into a spongelike material, and will need to settle to the bottom of the tank again or you will spray it into your equipment and ruin it.

[@bilzdraft]

This is awsome

[@MrAwesome4184]

This is a quality! Couple things to add. This is just what I have learned from class. I understand that he mentioned the fact that he has not specified a lot of the details because it does come from experience as I have learned in class. When you go to turn on the tanks you want to turn them a little bit more than what he said but not necessarily all the way. As for the oxygen and acetylene, 30 psi for oxygen is sufficient and you can go higher, but with the acetylene you just want it at seven psi. Also when you were setting off the torch do you want to back out the hoses so they do not burst from scoring at high pressure. What that means is turning off the torch valves on the actual torch, and then turning off the tanks. After you have turned off the tanks you want to turn back on the valves on the torch as if you were about to cut the steel. You’ll see the working gauge drop down to zero when you turn on the valves on the torches. Now the torch is ready for storage. Thank you for the video!

[@jake-mv5oi]

This lightoff procedure is different than I was taught. I open o2 valve on rear all the way, crack the acet valve, light the torch, open acet valve until soot disappears, then open the forward o2 valve until white feathers just disappear. Then sqeeze the o2 lever when the metal turns cherry red (not necessarily molten)

[@skiingrooster9808]

Your videos are very helpful. As a contractor, two days ago and for the first time I was exposed to these tanks and immediately thought about how dangerous they are. Now with some education, I'll have a better idea on how to talk to the welders about how they keep their equipment safe.

[@christophersiderius7758]

Also, soapy water and a foam brush around all fittings, regulators, gauges, lines, etc is an easy way to check for leaks before you start making flames or sparks

[@bradneufeld770]

One of the most important tips, besides the safety aspects, to enable clean reliable cutting was to keep the sides of the cutting tip clean. I cleaned the tips thoroughly every time that I used the torch. When the sides of the tip are clean, no carbon buildup, there was much better airflow into the flame. Also, we were taught in welding school to turn the acetylene off first as this lessened the chance of a burn back and also kept the tip cleaner as the continuing flow of oxygen pushed any carbon out of the tip.

Great video, I wanna add some things on: - There are publicly available charts with recommended pressures for the bottles (measured with the gas flowing) depending on the thickness of the steel you're cutting - use them to set your torch more precisely - the setting shown in the video will cut just about anything, it just may be overkill for some thinner metals. - Also consult OSHA's (or other country's equivalent) manual about the shade needed for cutting/welding - acetylene and plasma both require shade 5 iirc, which is readily available at many tool and home improvement stores. It's really unpleasant to look at a neutral or cutting flame at the very least and probably not helpful to your eyes either. I am pretty sure though that acetylene torches do not emit UV radiation, only infrared, they are still bright af and you only have 2 eyes. - All connections are brass on brass - never use sealants or tape to get a seal because it will react with the gases unpredictably (or predictably and violently). Don't crank down on them too hard - just enough to seal and you can check for that seal by cracking the bottle open with the tip valves closed, then closing the bottle once the pressures stabilize and noting how long it takes the pressures to go down. As long as it takes a couple hours you're good, one of my bottles takes about a day to fully go down but that one has a new regulator and hose. There is probably a better way as well, this is just one of them. - Work manuals will tell you to disassemble the torch fully once you're done with it - no one really does this and there are no real ill effects. Do, however, inspect the connections and hoses for cracking before opening the bottles, and purge the gases out of the torch when you're done with it - close the bottles, open each valve one by one until the pressure in the regulators goes to zero, then close the valves. If you shut off the torch improperly and it won't re-ignite, this is also the way to "start anew" - bleed, open again, and try again. - The acetylene bottle should only open 1/4-1/2 turn so in an emergency it can be closed with one twist of the hand. It still gets enough flow to do the work. If you transport the acetylene bottle and have to lay it flat, let it stand vertically for a couple hours before use - the contents are a mixture of gas and liquid confined within a sponge, you want the liquid on the bottom and gas on top or you'll have major, major issues when you try to use it. - If cutting rusty, flaky metal - WEAR THE FACE SHIELD. Metal WILL splash into your face because only the outside flake is molten. This applies to repairing rusty farm vehicles/equipment, car body repairs and restorations, and other situations where thicker, rusty metal needs to be cut. - If cutting overhead or the scenario directly above, invest into a leather welding jacket and hood. At the very least, wear several thick layers of clothing that you don't care about - and never wear synthetic clothing because it WILL melt to your body. Wearing long sleeves with a collar is the very least I would do, and welding gloves so you don't worry about giving your hands third-degree burns. - Proper footwear and leg wear is a must - work boots and pants, or at the very least thick jeans. Regardless of the position, your legs will get hit with sparks and it's really unpleasant. This is a very cool and useful skill to have, and indispensable if fabricating or working on vehicles subject to the weather. The cutting tip can also technically be used for heating, just stay off the oxygen blast lever and set the flame to neutral.

Been using the cutting torch since 12 years old. 30 years later I don't use one near as often because I have a lot of other better ways to cut metal. But there is still a lot of jobs in the shop that the torch is the best and most efficient way to do the job.

“Let’s say you’re a grown up” haha, I remember when I thought those existed.

I would pay money to see Scott Wadsworth in a full beard, wearing those Oakley Holbrooks... Oregon, boy, for sure.
