To the people saying why not use a band saw or why didn’t they lay the slab flat, the purpose of this video is purely to demonstrate the cutting capacity
The part has to be warmed up to 700-900°f for a nice cut. You can cut it way hotter than that but at my work we use hydraulic tables for leveling and squaring of parts and if the parts are too hot lines can burst and if it hits the part you have a really sick looking flamethrower which is usually something you don't want to happen. but ya I bet that piece of steel is pretty fuckin hot, but not glowing hot
If you haven't already figured it out after this long, I'll give you a few good reasons. 1. Hot liquid metal flying out of the side wouldn't be fun for anything in the immediate area, so a vertical cut pushes it downwards into a container placed there specifically for that purpose. 2. Gravity would make things very difficult after getting so far into the cut, because the steel above the cut would start drooping more and more as the torch gets to the end of the cut. 3. Cutting horizontally all the way across solid steel would most likely need to be raised and held in the air to even work right. That way the metal below the cut could just drop.
Thank you everyone for watching this video and shown your interest. The purpose of this video is to demonstrate the cutting thickness and the power of gas cutting.
The biggest ever cutted block of mild steel was 3500 mm in thickness. It was cutted with an acetylen-oxygen-gas mix in a German welding shool. It was en experiment to find out, what is the max. possible capacity.
@@TomFromRUclips Yes, cutted with The LINDE GROUP was make this test to demonstrate the power of that cutting methode. I can show You a video from the German "Von Schaewen AG". They producing a part for an exhebition. The thickness of that part is 1750 mm. There is cutted a hole in the middle. Here the Link: ruclips.net/video/TEkuEj0XlRU/видео.html
I used to cut 100 mm plate which is 3.9737 inches @ 350 grade for 48 tonne ripper shanks at my old job using a number 2 tip with an LPG/OXY mix Had to pre heat the fuck out of it though but it
It's really not the unsafe. The biggest danger is if you don't turn the feed rate down before entering the cut. When that happens it wont cut all the way through and forces liquid steel back up and out at a couple hundred psi so it shoots all over the fuckin place
Warren Armstrong man, get 2 homeless guys working for meth with a bandsaw and you'll have that cut in half the time, and you won't have to grind off all that slag....I guess I'm gonna have to bring that up with my boss😂
increase the size of your little friend down there, dude, always work ( i did it already hahahah) naaah, if you need any help about that just take a look to the Tom Candow´s "Penis Enlargement Remedy" book, a cheap solution for a big problem, your gf or any woman around will never be icehearted with you again hahhaha, ;)
@@carloko08 LMAO, I kick their ass to the curb if they don't like how I am. I was just making a joke but I'm guessing it went over yet head 😂. My current gf is a sweet heart 👌
Yeh my Chinese cut 50 claims 12 mm clean, lol can barely get through 5mm max cut lol. Still went alright cutting out rust which is all I got it for tho.
I didn't see anyone mention the little black stick the guy was poking into the flame. You can use a small piece of steel to "seed" the starting of the cut. Get the cut mostly up to temp then just like he did, use a little piece to kick it off. Works great when your torch isn't really big enough for you're in a hurry.
The first time I heard about an Oxygen-Lance torch was , in England , a foundry accidentally broke and dumped an entire ladle of molten metal on the floor , which filled the room very thick . Thats what they came up with to cut it up , because nothing else worked .
That’s genuinely an answer to a question I’ve always had. I watch a lot of those How It’s Made here in the 🇬🇧 and I always wondered, what would happen if that ladel fell from hoist? Now I know :) so thanks 🙏
@@GrahamDIY ,The original ones had a pipe to feed the oxygen for that length , the pipe was consumable , and burned up , and kept having to be replaced . Pure oxygen went down the pipe , while the igniter flame was oxygen- acetylene . They must have figured out how to get the oxygen pressure high enough to reach that far , and in a straight line without cooking the torch and blowing the slag back , you know what a mess that makes . My hat goes off to their technology .
That is honestly astonishing. Very impressive. Genuinely didn’t think that would be possible. Is it just the massive pressure that enables 850mm cutting, along obviously with the heat?
@@s.weldingandfabrication4287 Not exactly. The pressure of the cutting Oxygen does not blow away the metal. If this were true you could do it with air and you would also be able to cut any metal. But you can only cut Ferrous metals with Oxy/Fuel. What your seeing is a chemical reaction. The steel is heated to a temperature which allows for rapid oxidization, the pure oxygen is rapidly rusting or burning the steel away.
@@geoffmooregm that is correct it's a chemical reaction I freaked my friend out cutting 1 inch then told him to turn of the fuel yup kept right on cutting 🤣👍
@@juancabell77 yes you must provide enough oxygen to react with all the iron in the kerf of the cut. Tip orifice size and pressure both play a roll. You will notice some types like an AC tip will use low pressure and a big orifice. But a machine cutting VVC tips will use a small orifice and high pressure. VVC tips require 100psi of cutting pressure when cutting 1" material.
@@ciroc_lobster4052 No. It is the oxygen jet stream in the core of the flame that burn iron (converting it in iron oxide) the "tool". The fuel is needed only to heat the steel to the temperature in wich it can burn when in contact with oxygen. Theoretically after the oxygen started to cut you can shut off the fuel, because iron is the primary fuel of the reaction. Fuel is needed only to make sure that the reaction remains stable.
@@henryrollins9177 yeah I'm pretty sure this was just a demonstration of there cutters abilities. However being able to cut with this system could be very useful in remote areas or were a complicit cut was needed 😁👍
At first I was wondering... that flame didn’t look like it could cut through almost a meter of steel... then the cat gets close to the flame and does _something_ and *_woosh_* they go full power... very impressive gas control !!!
The last 2 times i was in on oxy/fuel(once compressed natural gas and oxy, the other oxy/propane)of shape burning 26" few years later 27&3/4" thick mild steel each time. The vise presedent wouldn't allow non-envolved personale into the building without shooters ear muffs(easy 120 decibles ear killing noise). First time was with anceint NCG torch. Second was with an experimental Koike torch. One guy had a garden hose on full blast while the other dialed in speed, pressures,and gases. There is business/sales opportunity for Oxy/Propane+black Iron powder shape cutting extreamely thick metals(tool steels, nickel,stainless, almost ANY TYPE of metal). Ordinary oxy fuel gas torches won't burn any steels with higher than 7% nickel. Simple shapes in thick tool steels can be shape cut from slabs or ingots rather than back logged foreging.
A typical application would use mapp gas and Oxygen. But they would come from storage tanks on the property. Oxygen cylinders do have the necessary pressure for this job, but the mapp gas tanks do not. A large storage tank is required for them to get enough pressure. And just for the record the cutting tip that was necessary for the 7.5" cut cost $45 and is burnt up after one use just to start the first hole. Why they didn't drill a hole first I'll never know.
@Thale Leaf it's not meaningful in a cutting operation. All you have to do is get the steel hot enough to burn propane or even natural gas does that quite well and is both a lot cheaper and a lot safer to handle.
We have a torch just like this at my job and the part has to be heated up first to around 700-900°f to prevent that. Also it cuts faster and turns out nicer
The mixture looks rich... I’m sure these guys know what they’re doing but it’s interesting this beast has to be set different than the track torches I’ve used. That said, the thickest I’ve cut is 150mm
1:03 uhh bro...brooo....BRRROOO WTF YOU DOIN!? GET TF OUT OF THERE THIS TORCH IS CUTTING THROUGH 850MM OF STEEL! TF IS WRONG WITH YOU!? GET A LONGER ROD DAAAAAMN!
And he was fuckin trying to hold is hand in front of his face like that would do something. It's cutting through a bunch of steel, your little hand isn't going to do shit.
@Wance Lemuel Yea I figured. BUT....that heat is punching right through 850mm of fucking steel. And the thickness of your hand is maybe, what, 20-30mm at the thickest?
@@johnsumner2987 the heat is both a trigger and a by product of the burning steel. Yes, the steel burning is what does the "cutting", if this were stainless steel it would not burn...stainless is a mess to torch cut it just melts
@jeepnunh Yea the burning steel doing the cutting is the same thing as an oxygen lance they use to cut through ship's hulls. The same thing can be seen when you take ultra-fine steel wool set it on fire and spin it around. I didn't know that SS didn't burn like that. Is it because of the abundance of Chromium and Nickel?
What amazing power. But is there a reason why they don't rotate it 90 degrees and cut it the other way? Longer cut but not as thick. I suppose if you have this kind of equipment it doesn't really matter.
@@redacted9907 5psi acetylene and 40psi oxy, you can use 3psi fuel and 30 psi oxy but eh . also face your torch against whatever youre cutting so it pre heats the metal as you move the torch forward into the cut.
@@johndowe7003 good tip, but what size tip is that with? I personally like to run a 00 tip with 7-8psi acetylene and 40-45psi oxygen for 3/16" up to 3/8" for production purposes. You can freehand or use a cheater bar for straight cuts. Also run the torch across your cut patch a few time quickly prior to cutting. Just keep your ports clean and maintain a neutral flame and you shouldn't have any problems.
@@redacted9907 its for a triple ought i think (000) im not sure what tip size i have on my torch. i dont like running that high of oxy cause its its waste. usually i can get two bottles of oxy for one bottle of fuel before i have to refill. so its saves me more cash, i free hand everything and use a soap stone if i need to mark things for 8psi fuel i would go 50 psi oxy or 60. but you dont need to go that high unless youre getting 3inch plate . 5 psi and 40 will cut up to one inch no problem. i personally think youre wasting too much gas but if youre not paying for it go for it haha, smoke em if you got em kinda deal there. i run my stuff in my own shop so im about cost effectiveness over speed.its all personal preference. for thinner stuff like i go to 3psi fuel and 30 psi oxy.
@@johndowe7003 Yeah i hear ya but the thing to remember is cost difference between gas and what your guys make per hour. If it's you by yourself then i understand. But with the setup I described previously, i can cut about 80 to 120 ipm depending on preheat and thickness. I work for someone else and at the end of the day, gas is an expense. Expenses qualify as a tax deduction at the end of the year. Just keep good records and you may be able to increase your bottom line profit. Oh, to be clear... those settings I mentioned, that's just max flow at regulator. I set my torch with the knobs based on application. Most of the time I'm not running full open. I change tips not flowmeter settings. Saves me time and increases my productivity.
I like how the guy stuck the probe in to see how hot it was getting then told the other guy to move it down an inch and bam it started blasting through that steel like nothing. If you ever doubt that an inch makes a difference ask your wife/girlfriend or watch this video
I presume you mean some sort of armor-piercing tank shell. Those work by generating a plasma jet. I think you have just invented the world's most expensive plasma torch.
What are they normally cutting using this that they don't care about the surface texture or loss of material? If it's for junk metal why not recycle..then material lose is still and issue because you are losing money. It's a cool demo, and an awesome amount of power i just don't see the use case. I don't work in the industry so it's no surprise i wouldn't know. I am genuinely curious.
Impressive cut! I'm surprised you cut the torch off so suddenly without leading out. I'm assuming holding a tight tolerance isn't really an issue for gouges on lead outs.
Why is it being done upside down? Is it just because it's a test that is showing how thick metal it can cut or it must be done this way because of some reason?

@@johndowe7003 good tip, but what size tip is that with? I personally like to run a 00 tip with 7-8psi acetylene and 40-45psi oxygen for 3/16" up to 3/8" for production purposes. You can freehand or use a cheater bar for straight cuts. Also run the torch across your cut patch a few time quickly prior to cutting. Just keep your ports clean and maintain a neutral flame and you shouldn't have any problems.
@@redacted9907 its for a triple ought i think (000) im not sure what tip size i have on my torch. i dont like running that high of oxy cause its its waste. usually i can get two bottles of oxy for one bottle of fuel before i have to refill. so its saves me more cash, i free hand everything and use a soap stone if i need to mark things for 8psi fuel i would go 50 psi oxy or 60. but you dont need to go that high unless youre getting 3inch plate . 5 psi and 40 will cut up to one inch no problem. i personally think youre wasting too much gas but if youre not paying for it go for it haha, smoke em if you got em kinda deal there. i run my stuff in my own shop so im about cost effectiveness over speed.its all personal preference. for thinner stuff like i go to 3psi fuel and 30 psi oxy.
@@johndowe7003 Yeah i hear ya but the thing to remember is cost difference between gas and what your guys make per hour. If it's you by yourself then i understand. But with the setup I described previously, i can cut about 80 to 120 ipm depending on preheat and thickness. I work for someone else and at the end of the day, gas is an expense. Expenses qualify as a tax deduction at the end of the year. Just keep good records and you may be able to increase your bottom line profit. Oh, to be clear... those settings I mentioned, that's just max flow at regulator. I set my torch with the knobs based on application. Most of the time I'm not running full open. I change tips not flowmeter settings. Saves me time and increases my productivity.
That torch was so expensive they couldn't even afford a face shield for homie 2 feet from the torch lmao
I like how the guy stuck the probe in to see how hot it was getting then told the other guy to move it down an inch and bam it started blasting through that steel like nothing. If you ever doubt that an inch makes a difference ask your wife/girlfriend or watch this video
For me, looks like magic !
There’s old crusty guys out there, that can do that by hand
No joke
Wouldn't it have been easier to sleep the block on the longer face and then cut?
Then need to change title to oxyfuel cutting a 150mm no fun at that.
so its just for fun....
It was just a demonstration of the cutter's capabilities
Why didnt they juts rip it apart at the dotted line?
They should use this instead of the electric chair or lethal injection
Lets start with Hillery
I wonder why some americans are as dumb to write bullshit like that.
Humans are sacks of shit and water....It would result in series of steam explosion and huge unsanitary mess. Also horrible smell.
Agreed
But doesn't that cut away a lot of unnecessary material? Looks like the cut is up to 5cm wide.
Fire hot!
That's one hell of a torch. Biggest downside with cutting like this is the loss of material.
Cutting with water jet way more satisfying
I was just about to comment the plate isn't 850mm thick. But then, I watched the video and I'm MIND BLO..💨
That is pretty impressive.
m1 abrams APFSDS could punch right through that i was looking at this for reference impressive
I presume you mean some sort of armor-piercing tank shell. Those work by generating a plasma jet. I think you have just invented the world's most expensive plasma torch.
That torch could make a hell of a acetylene bomb. Wake the neighbors up big.
🤣👍
Chuck Norris could do that with a karate chop.
He could with a tooth pick
What are they normally cutting using this that they don't care about the surface texture or loss of material? If it's for junk metal why not recycle..then material lose is still and issue because you are losing money. It's a cool demo, and an awesome amount of power i just don't see the use case. I don't work in the industry so it's no surprise i wouldn't know. I am genuinely curious.
Just curious but a bandsaw wouldn't be a better tool for that job? Or is that to big for even industrial bandsaws.
@someone else shape cutting? Like odd or irregular dimensions?
impressive demonstration
Нет чтоб вдоль резать, они поперек. Лошадь позади телеги тоже запрягут?
Thaught he was lighting a cigarette there lol
They seem a little cavalier about safety. Good thing that guy is wearing goggles a foot away from the flame.
That's the Japanese for you
the guy is wearing 100% fire retardant clothing a hard hat safety boots and safety glasses wtf else do you want the guy to wear a sprinkler system ?
Damn, I thought I was doing gr8 cutting 9". You must have been using very high pressures
That's what I was thinking too. Not to mention stupid amount of volume
It's basically a lightsaber, yo
That guy will be on LiveLeak any days now
*1:27** Kylo Ren Lightsaber*
зачем вдоль резать если можно поперёк?
what size of the nozzel?
Impressive cut! I'm surprised you cut the torch off so suddenly without leading out. I'm assuming holding a tight tolerance isn't really an issue for gouges on lead outs.
Why is it being done upside down? Is it just because it's a test that is showing how thick metal it can cut or it must be done this way because of some reason?
What was the guy doing right next to the tip with the rod poking at it?
Wow. Very impressive. Thanks
Must have one hell of a pressure of oxygen 👍🇬🇧🏴
Nice, now have a guy stand up there and lance it like a real man!
Verygood video 1like
Damn sure wouldnt lite my cig with that damn thing!! That was cooool!!
just think, 50 years ago they were making toys out of old soup cans while America was using heavy steel to make things. now its been switched around.
there must be a better way
like pouring the molasses into a bowl of hot pan and then hopefully the sauce is ready.
The one guy clapping at the end lmao
