Bruh what, turn the oxygen on MAX?? Idk what torch you're using but in the beginning the black smoke indicates your oxygen was closed and not "all the way up"
Have to love all the negative feedback when you can out cut someone with a torch. One of the better videos you can watch. It's very simple. Keep a clean tip and use the right sized tip for the metal. When you pull the trigger your flame should not shrink or sound like it's being blown out. When you get really good and dial in your settings when you pull the trigger your flame will get bigger...
hey great job man, I have a cutting rig and I had a stroke a few years ago and it damaged my frontal lobes in my brain so I have to re-learn alot and you tube is a great tool for me, before my stroke I worked at one time in a radiator shop putting old tanks on new cores, and putting a torch to a fuel tanks that leaked it was butitia bros radiator and auto repair in rockford IL I made new ac lines for cars, custom rad. for hot rods, you can cut a good true line my man and them holes were great you have skill, so I been turning my gas up too high, see I have 2 lines put together or hoses you get adapters that way you don't have to move your tanks, thank's alot
@@willgund779 No not burning. It's rusting/oxidizing it away. A chemical reaction also with heat. Please do you research before talking. For us who use this and who have bee taught this know how it happens and have learned why.
@@jacobkudrowich What's hes explaining is that with the Oxy-acetylene process cutting steel, you aren't "melting" the metal, the process is a chemical reaction that essentially speeds up the "rusting" process which severs the two pieces. It's difficult to explain, but as he stated, it's why you can't cut aluminum with it.
That first cut is beautiful, artistic, fantastic, and a variety of other adjectives. I wish had that skill. Practice, practice, practice. Thanks VERY much!
+incrediblefruit I did aluminum castings for two days where it was about 80-90F outside, that sucked as soon as you put on the leathers, but it was still fun as hell
You have a good clean cut which just takes experience and time to develope, when I started my welding career 35 years ago in a ship yard as a welder we had people that were called burners that only used a cutting torch all day long. They have that unique clean cut you have!
@spacebrdcst thanks for the thought but people should only click them if they are interested in the product. If someone gets too many clicks they can lose their adsensemoney for the whole day or until it gets straightened out. I will make some more vids anyway when our burn ban is over. Thanks again
@lilsouthernbell20 It depends on what kind of torch you are using. If you have a victor manual read it because your way is wrong. either way it wont blow up so stop being such a puss ok welder man.
When you want to cut a hole I use a center punch and make a dimple then when you preheat the iron a small bead will form in the dimple and when you put the oxygen to it this bead goes right thru. It also seems to form quicker than just heating the iron.
It cuts by oxidizing the metal. Really it makes it rust much faster than sitting out side and waiting for surface rust to happen. Really all your doing is rusting steel, that's why it doesn't work on aluminum and some other materials.
No I really did mean ferrous metal you can't cut aluminum, copper, brass, bronze and some other alloys with oxy fuel torches. but you can melt non ferrous metals.
Nice video. But you did go pretty fast when adjusting the flame when first lighting the torch. And what happens when you press the Oxygen Handle on the torch? How much comes out? Can you cut without using the Oxygen Handle?
You should make the inner cone of the flame as tall as the to be cut material, otherwise you will have to much or the little power for the cut. With starting the cut aim at the corner and hold the torch 90 degrees (so there is no point on the cut meterial) to the piece you want to cut. First start of at 45 degrees on the cut. Then hold the torch some 65 to 70 degrees to the cut, so the torch first goes through the side, and dont leave the buttom piece of the cut not cut deep enough ( like on 1:34). Blowthrough is a bit much, but you should try to see how much seconds it takes in order to make a good cut through the material, thickness and kind of materials takes different times. This is what the book "Welding Skills" (OAW cutting opertations chapter 25) says about making cuts. Greetings, Jeff
@driftinthroughtime ok...in my welding class my teacher, who has been welding and using torches for the past 30 years says we should shut the oxygen off then the fuel off
@pROTPANDA It depends on how big the torch and tip are. this is a 0 tip so It can cut 3/4 inches easily. some bigger tips can cut several inches. you can also get really small tips to cut sheet with if you want to.
@CoolasIce2 you would need a special tip that draws air in. It would take longer. If it's really thick it may take forever to heat up. Oxygen is cheaper than acetylene. So you may want to use oxygen with it to save time and money. Some people braze and solder with acetylene alone but it's not as good IMO. The best thing for heating cost wise is using propane or LPG and oxygen.
@vochitoken This only cuts steel and iron. Plasma cuts everything. You can get started with this cheaper but plasma is cheaper in the long run. you would need a really expensive plasma cutter for thick steel but oxy-acetylene cuts really thick steel no problem. the oxy torch heats the metal more than the plasma so you will get warpage and other heat related problems if you are not careful like hardening.
you forgot to say one small step. helps make a better but cut. but make sure your comfortable when your cut, it helps your hands stop shaking so cut looks smoother
@BenHutchinson1 That's cool. Most people turn the oxygen up too much and the cuts come out real sloppy when that happens. Thats the main problem people have is too much oxygen.
wow, usually when i see people cut it an oxygen acetylene torch its really sloppy and ugly, you cut better with this than most people do with a plasma.
Cool Video. The oxygen is rapidly, well, very rapidly rusting or corroding the steel. That's why it cuts so fast. But the steel needs to be in a molten state to be susceptible to the rapid oxidation. ITs Chemistry.
So.... I'm by no means a qualified cutter but a couple things. I will say, SUPER jealous of those nice clean cuts you're getting.... They're gorgeous. 1. DO NOT completely open oxygen, open it all the way then a quarter turn back, it's just kinder on your nice tool. 2. DO NOT light your torch with a cupped hand, palm ALWAYS down. Acetylene is heavy and can gather in you hand... If you strike that sonnuvabitch KABOOM and sizzle goes you hand. 3. What the is that shirt you're wearing? Guarantee it'll melt or burn if you get slag or blow back on it... WHERE'S YOUR APRON!?! Your torch isn't "burning" metal, it's super oxidizing it with the oxygen, heating it up makes this process go faster.
Wish I would’ve found this video sooner, tried cutting a piece of 2.75” thick plate, after seeing your description of “too slow” I was definitely moving too slow. Couldn’t figure out why molten steel was flying towards my face and dripping on my beautiful concrete floor. FML!
@MrWhatthemonkey After a long period of use it can in fact hurt your eyes I've oxyfuel cut plenty of times without eye protectin but ANSI wants you to wear a 3 to 6 shade filter lens when oxyfuel cutting
@MrWhatthemonkey Yes since you are welding or cutting metal its a good idea to where safety glasses or a mask so the sparks does not get into your eyes. And wear leather gloves aswell.
@sparklerbombg it should be pretty cheap under 50 at the most.. the money starts flowing when you rent tanks and stuff like that but a refill/exchange isnt to bad
I'm referring to both of you: there's no apostrophe used in plural nouns.

(correct) I'm not an English professor, but I do correct mistake's on comment's and I smoke a pipe and wear reading glass's and cardigan sweater's. (incorrect) *I live in a cabin made of hard cover copies of Moby Dick, and I can recite Poe's "The Raven" in Urdu.
This is what the cutting torch does: Rust metal. Rusting is oxidizing. Oxidizing happens faster when the metal is warm, and also faster with oxygen added. The torch warms up the metal, then adds oxygen when you push the lever. What then happens is an instant rusting process, rusting straight trough the metal at an incredible speed. This is why this does not work on metals that don't rust, like copper and aluminium. The results with these metals is a melting process, rather than a cutting process
Great vid, Freddy. Hey, I picked up a "used" [customer returned] welding set up from an E bay seller Tadd Wholesale Supply which sells a lot of Harbor Freight customer returned items. Check it out. I paid $60, including shipping, for a complete set up like you have here. All I need are the tanks and gas. I have a question. If all I want to do is use the torch for heating, say a rusted bolt, so I can remove it, can I do that with only the acetylene? Thanks.
I have an issue where I get a nice clean cut as I'm going, but them about 1/2" behind where I'm cutting will them "pool" back up with metal. How do I stop that?
@12peter96 sry dude ur teacher was right 30 years ago but times have changed just like the world has, because of a study a couple years back they found if its A before O, theres less chance of burning occurring inside the torch head, havent u noticed if its O before A it leaves behind a small flame? does that seem right to you?
@12peter96 dude, there are different brands that have different ways of shutting down the torch. for example; Victor Cutting is a brand that gives instructions for shutting oxygen valve first. The torch i use, you're suppose to shut acetylene off then oxygen.
yes indeed, the oxygen is burning the steel, the iron in the steel is burning and turning into iron oxide, that is the slag you see. when it comes to turning on and off the torch, you can think about it in your head, and come to a conclusion. if you turn off the acetylene first, there will be too much oxygen and the gas to oxygen ratio will briefly become stoichiometric, aka the torch tip will go "pop". and then the acetylene will stop burning, leaving a small amount of acetylene in the air, and a bunch of oxygen, but oxygen is in the air, so it doesn't really matter. if you turn off the oxygen first, the acetylene will keep burning in the air, and creating soot, aka carbon powder, but carbon on its own is harmless, and unlike a wood fire, there is no ash, so really the only problem is the possible generation carbon monoxide. but even if there was some, it wouldn't be much, almost certainly not enough to worry about if you are in a ventilated area (as you should be if you're using a torch) probably the best way to turn it off, would be to turn both knobs down at the same time. or you could do the same thing, but before the flame goes out, stop and first turn off the acetylene, then there is no soot or possible carbon monoxide, and only a little tiny pop. these are just thoughts, not official instructions, but I bet it would work great either way.
the black stuff is called soot, the molden beads that hang off the bottom of the metal is called slag (you dont want that because it takes time to clean it) and turn of the torch A before O, Acetylene off, Oxygen off.
@freddytk421 which is the best option for for cutting thick thick metal ( more than 4 inches..... a 100 am plasma cutter or oxy- acetylene??? How long will it take with a plasma cutter than with the oxy torch???
hey boss your lesson was outstanding! i needed to use the torch to cut holes in steel that was eating up too many drill bits and i just couldn't get it going until i saw your lesson to hold the torch until it melts a little then let it rip. i usually use the torch for hvac work and never actually cutting steel but im good to go now i can cut anything! will it cut open a safe on a bank? loool
the oxygen is what cuts it, the pure oxygen reacts chemically with the molten steel and converts it to iron oxide, in short, the oxygen rusts the steel, heat is used to speed up the reaction.
@freddytk421 Hey I subbed. Where could I get used bottled of oxygen acetelene and a torch that is affordable..... or what is the best torch to cut faster if I had to spend the extra few bucks?
3:35; Your not burning the metal, its a chemical reaction called Oxidation. Carbon steel melts at around 1500 degrees celcius, but Oxy cutting doesnt (shouldn't) exceed 950 degrees, (ignition temperature)
3:35; Your not burning the metal, its a chemical reaction called Oxidation. Carbon steel melts at around 1500 degrees celcius, but Oxy cutting doesnt (shouldn't) exceed 950 degrees, (ignition temperature)
@driftinthroughtime lol sry to be that guy but when the slag is created by gas its actually called dross, slag is the byproduct of arc welding...the more you knowwwww.
@freddytk421 where could i buy the equipment to practice? I need the oxy acetylene tank, the torch, and the torch cords. Where do you recommend to to buy these things?
@clarencestanley ...... wow, sorry but when you pull the trigger the oxygen pressure just pushes out the molten metal thats it. its just like a controlled form or melting
How can I purchase a smaller and portable set which I can carry along anywhere I go. Or, is there a smaller set? Let me know how I can get it, if possible
when will you guys learn that its proper name is raw iron or steel i get annoyed sometimes when i hear people say oh i was cutting metal with a cutting torch....
Bruh what, turn the oxygen on MAX?? Idk what torch you're using but in the beginning the black smoke indicates your oxygen was closed and not "all the way up"
No wrong you turn up the acetylene fuel until black stops then you mix in oxygen he is using a two stage torch not a one
Wow, I learned most of this by trial and error. At least I thought I did. Your cuts look like a bandsaw!!! Back to the drawing board.
Gotta give you credit on the straight cut and the round bolt holes though
started practising welding today. accidentally welded the vice and the metal together lol
hows your welding now

Always open acetylen first.
Always close acetylen first.
why?

Because doing so prevents flashback.
can you elaborate why? I am new/amateur to cutting and would like your opinion!

holy shit these cuts are clean

You want to have your torch at a slight angel pushing heat ahead of your cut, this preheats and makes the cut far cleaner and you also cut far faster.
and it’s clean- no bubbled up slag stuff hanging off the edges?

and face protection, hat is a plus too. oh and how to check for leaks, store tanks and such....dont just start cutting.
