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
that's how I was taught in welding class. back in the late 70s. a lot of comments on turning on the acetylene first. the first knob allows oxygen to the torch. then he lights the acetylene. then he turns on the oxygen. so the acetylene has been lit first. I give this video a thumbs up. Thanks for the video.
That first cut is beautiful, artistic, fantastic, and a variety of other adjectives. I wish had that skill. Practice, practice, practice. Thanks VERY much!
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!
You are correct. Oxyacetylene cutting actually burns the steel. The red hot steel will burn with the oxygen, producing even more heat. That was an excellent video. That should improve my cutting ability.
+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
Oh man!!!!!! If that camera was zoomed in on the torch only I would have believed it was a machine cutting that line good how to video as well thank you
First of all, want to complement you on your skill. I need to practice cutting with this info, I've been wasting fuel this whole time, thank you for teaching us! Great video!
Adjust for a neutral flame. It oxidizes the metal instead of burning it. I know it's looks like burning. You have a steady glide. Nice video thanks for posting.
nice handling and good video . allways remember Turn on Acethylen first , and cut off acethylen first . its the most easy way , and the most safe way . people think they can handle to turn the nobs and mix oxygen and acethylen in the right mix and ignite , but allso educated blacksmiths and skilled metal workers pop the flame and making backslash into the tubes , and in worst case into the acethylen tank without you knowing it course most people forget to feel the tank with theres hands.
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!
I am taking a very chalenging welding class for school, but since I started watching your vids I found alot of helpful tips and stuff. I just subscribed, just make sure to keep posting more videos.
That was really good. Thank you for showing all of that. I'm buying my 1st one for a tiny job & have zero experience so I really appreciate your video!! 😃👍
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
thanks for the vid it will help for my class cuz i really suck at torch cutting but with what you've explain in this vid i'll be able to fix what im doin wrong
Awesome video dude! Today I practicing my stick welding with that small HF arc welder. Getting ready for that railing project. I got the steel delivered today.
Once upon a time I had job where I did a lot of ‘ line burning ‘ where i cut plate steel using a motorized torch holder on a track. You get it going just the right speed and steady ness and the slag just shoots off like a jet and the edge looks like you cut with a saw, sometimes even smoother. I remember older time guy showing us how to be able to cut very thick steel with a number 1 tip. Steel you might need a number 3 tip for. You cleaned out the center oxygen hole very carefully with tip cleaner then adjusted the oxygen for a delicate light pressure which would cause the cutting flame to have a very long center. Like only about 5 lbs pressure instead of 20
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.
I've never done a thing with a torch and metal, and I have no need really, but that first cut makes me want to get a set just so I can learn to do that.
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.
Thanks man I learned to use the torch in my welding clas in highschool and it’s scary using it cause your not supposed to let the tip of the torch touch the metal
nice video! i'm certain i'll be able to do this the first time i try, and then just because im dumb, never ever again. but that doesn't matter, i'll be able to do it the first time and really well thanks to your video.
hey brother nice video I've been burning for about 8 years now I recommend you do not burn on top of cement the cement will explode if too much molten splatter or slag falls onto it what are the thing to emphasize is to always wear safety glasses gloves sleeves or letters and a burning shield
+werm I've noticed that when I cut through flat bars and the concrete floor spits and actually sets on fire sometimes plus if you burn a lot in the same area, the burning concrete kicks up some really bad smoke so not recommended...
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.
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.
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
@@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.
Good stuff man, I bought that harbor freight torch set you recommended in another video, and I honestly can't see a difference from the victor I learned with.
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
Always angle you flame toward the way your cutting if possible ( not straight up and down to cut) so it preheats the metal coming at the torch head and allows it to melt faster and be ready fornthe oxygen to blowout the metal.
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
@@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.
Look more carefully - he's opening the main oxygen valve all the way before doing anything else, but the secondary valve is shut. He lights the acetylene and adjusts it, then starts to open the secondary to add oxygen to the flame. This is the same way that's specified for my Victor torch.
I did this in class for the first time yesterday, and I must say my cuts did NOT look that great, you should have seen the slag, I may as well have been welding..lol I noticed you didn't rest the torch on your wrist like I was told to. I'm gonna try the method I just saw you use in this video in Monday. Anyway great video.
@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.
@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.
@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.
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?

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

Very smooth cuts - nice. The plug that dropped out of the hole was perfect.
You are correct. Oxyacetylene cutting actually burns the steel. The red hot steel will burn with the oxygen, producing even more heat. That was an excellent video. That should improve my cutting ability.
ur pretty legit dude. thats probably the straightest free hand cut ive ever seen. kudos to you
Thank you! I came here through a video on the Russian T-34 tank, where a comment said it was "torch cut". Now I know what that is :)
I miss doing this, I think I'm going to get into this again. This has to be one of the coolest careers!
+Secret User Great in winter but not so great during a hot summer and right now it's a heat wave here....
+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
started practising welding today. accidentally welded the vice and the metal together lol
hows your welding now
@@mclewis991 Can't reply, welded hands to keyboard, I assume.
@@neolexiousneolexian6079 lmao 🤣 😂
How’s it now
lol dude i was on the cutting torch at our community college and i was going wayyy too slow and i was welding the plate together🤦♂️🤦♂️
great i found a video of exactly what I used today at school! Well time to show my parents!
Deadlyguy135 I learned in auto tech, I have atest on it tommorow
Oh man!!!!!! If that camera was zoomed in on the torch only I would have believed it was a machine cutting that line good how to video as well thank you
First of all, want to complement you on your skill. I need to practice cutting with this info, I've been wasting fuel this whole time, thank you for teaching us! Great video!
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?
Always open acetylen first.
Always close acetylen first.
why?
+VerticalWit BOOM!
Because doing so prevents flashback.
can you elaborate why? I am new/amateur to cutting and would like your opinion!
i wanna know too
Adjust for a neutral flame.
It oxidizes the metal instead of burning it. I know it's looks like burning. You have a steady glide. Nice video thanks for posting.
Nice video. I'm a journeyman electrician ibew, and I did my first year apprenticeship on a electrician welding crew. Fun as hell.
You have a nice steady hand with fine motor control. I can burn the nut off a bolt & still use the bolt but my burning still does as nice as yours.
Excellent video. I am a novice at torches, and this helped vastly. Thank you.
Best Torch welding tutorial i have encountered so far.
Nice!! Next time I have a few minutes at work I'm going to try and cut a hole. Great video
Amazing precision and efficiency with a torch.
You sir have a very steady hand. That was such a clean cut
Those plugs you cut out....damn...bravo!! My hat is off to you friend👍
Thanks for a very clear and concise video. This was a great refresher after learning in person some 15 years ago

thank you alot for this vid i have to star cutting with torch this year company got rid of metabos and i am new to torch you help alot
I'm in Grade 10 and I started automotive. I lit the torch and it's really fun
perfect video. exactly what I was looking for.
Good clean tips are critical for good cuts. You do an excellent job!!
i just started my first welding class and it covered this. thanks for the review
I like the simplicity of the explanation I just started welding for hobby projects only but every time I shut it off it pops.

Why can’t every body make instructional videos like you.

I want a teacher like u, my teacher yelled at me and told me to read the book, but the book isn't specific enough.
You are doing good cutting metal 🤘
Nice video. Showed it to my welding 1 class and it was very helpful.
straight forward and to the point. good work.
Nobody seems to explain the desired cone sizes as concisely as you did, and I'm not sure why.
Oxegen is rusting the iron that's why you cant cut aluminum
Aluminum forms oxides just like iron, I imagine cutting it can be problematic cause of the low melting point and high reactivity of burning aluminum.

@static14 we were told to do O before A bacause if u shut off the A u could leave the O open a little bit, emptying the tank
Your alright at cutting! I just learned and I can honestly cut better than that!
Great video! Thanks for your time!
Look more carefully - he's opening the main oxygen valve all the way before doing anything else, but the secondary valve is shut. He lights the acetylene and adjusts it, then starts to open the secondary to add oxygen to the flame. This is the same way that's specified for my Victor torch.

Lol I tried torch cutting too I sucked but I'm getting better at it
ur tip on the end of the torch might be bad to, normally will blow slag everywhere if it is
@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.
@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.
Nice video. Since I don't weld with my torch I use propane. Much cheaper and cuts just as well.
@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.
Thanks for the video it was really helpful for me.
el primer corte es de lo mejor que he visto
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?
excellent video. that was a beautiful cut. however id like you to make a video showing is drag lines or Kerf line.
