Mine was turn gas until the black smoke was gone, then add oxygen until you could see the cones at the tip clearly.

Pipefitting apprentice here and this is exactly how we were taught for beveling and cutting pipe. To each their own. I know some people like running shorter flames but a longer flame and slightly oxidizing has always worked best for me
I feel like many points were missed lol, when you set your flame. I turn up the acetylene until there is no more black smoke and turn up the oxygen until you can see the individual cones and pull the trigger and set until you can see the individual cones. Maybe I’m wrong seems to work flawlessly, have cut very thick material and looks decent too
@@WesternWeldingAcademy what are the differences in cutting with the way the torch is set? I was taught to get the flame down til you can see the cones on the end of the tip. Do you get a smoother cut with your method? Never tried it.
Im a senior in high school right now, Ive taken all the basic years of welding and am now taking an independent study and going to be a TA for a welding 1 class so the last two weeks of my life has been watching do this one repeat for at least 2 hours a day.
Well you're watching the wrong guy for that man. This guys a sham, you don't have the flame that long that's not gonna cut shit, even if it somehow does its gonna blow molten metal all over your boots and legs, probably face too if you're unlucky. You don't turn the torch off with oxygen going first, the torch is still going in the video when he does it which is pretty obvious its the wrong way. Acetylene always goes first both starting and stopping that's the golden rule.
well, this isn't how I was taught, I was just taught how the finished flame should look and that is it showing the 6 cones. I was also taught to never start the torch with just acetylene, tiny bit of oxygen should be on to not soot up the nozzle and never turn off the oxygen before the acetylene when extinguishing the flame. I don't know how right this is but it has worked so far.
I like a nice long jet stream. Super clean tip. Proper sized tip. Open acet on torch all the way. Adjust using regulator. Low end of the recommended oxy. Clean cuts all the time.
*Tip* : If you turn off the oxygen valve after the acetylene valve, there may still be some residual acetylene in the system. If the oxygen valve is closed suddenly, it could cause a brief flare-up or a small popping sound due to the excess acetylene burning off. This is generally not recommended as it can be hazardous due to the potential for uncontrolled burning.
I like to open both up just enough at the same time. With practice, you get it to light up just right most of the time. That way, i can avoid inhaling the black floating strands that you just put in the air by leaving the acetylene on in the beginning.
We are taught to ignite via oxygen on befor the acetylen because theres like a swivel inside of the torch handle, which can break if acetylen is inited without oxygen. But thats mostly for welding. I like to say, 1/8 turn of oxygen 5 bars of pressure 1/4 turn of acetylen 0.8 bars of pressure.
He left out the last adjustment, hold the cutting ox on and readjust your flame to neutral, also the oldest saying around for shutting off, "red before green or you won't be seen" it's the ac that's burning, get used to turning the ac off first so in case of an emergency you will know what to do.
One time at Job Corps, so guy decided it was an amazing idea to try and use a grinder to remove a ripped sticker on an acetylene tank. My instructor tackled the absolute shit outa him and saved the entire shop from getting killed.
I was always told you start the gas then the oxygen. Then adjust it so the small “triangles” at the base of the flame coming out the torch are sharp at the end. Hit the oxygen and make sure it won’t blow out and your good, adjust as needed
Also, am I the only one who starts it with a tiny bit of oxygen and some ac? There's always a lil pop but not much adjusting, and there is alot less maintenance on the torch because you never burn pure acetylene.
I love my portable hot wrench. It’s got small tanks and a mid-range torch. I toss it on my back like it’s the first day of school, crank it up full and loosen or cut through anything I see. Mmm, great investment.
The way I was taught, light it, turn ac till you can barely see black smoke, then turn oxy on till you can see blue cones, squeeze and adjust till its just sharp blue cones. Adjust your angle for cutting as needed
He shut both off, and a small flame like that won't cause any issues, i work in trash and honestly been impress with how little things catch fire for sparks or just a acetylene flame
2 important things not mentioned. Flame speed (acetylene pressure) and material thickness. The preheat flames are just that preheat. Once the rapid oxidization starts (cutting), you can shut off the acetylene and still keep cutting. The process doesn’t require acetylene once it starts. The thicker the material the more oxygen pressure basically (without getting into tip sizes).
@@windchiller6951 you stay away from torches as well if you shut your cutting fuel off before oxygen. Thats the reason torch sets come with flame arrestors
@@windchiller6951 yea, how dare you do things the right way and not risk blowing yourself up! You shouldn't be around torches until you know how to operate them dangerously
Awesome!

Yeah, first the acetylene, at least when you welding, but the two thing is very close to each other, maybe there is a difference in the mixing process (and when in the beginning you add a lil bit of o2, the flame not gona smoke like snoop)
@@240sxRule yeah that's how it works, but you have to have heat. Where does that come from, certainly not the reaction between the metal and oxygen. You have to have fuel.
I was taught in welding class in high school that of you look close to the nozzle you can see tiny little dark blue flames and you want to make sure those are all the same length
The oxygen pressure at work is a bit over 220 psi, and the fuel is regulated down to 80 psi by the time it gets to us. We have to turn the torches up a Lot more than that if we want a true neutral cutting flame
Unless the angle is bad it doesn't look like enough oxygen. I use a much more neutral flame. The one in the video looks like mine the oxygen bottle is empty.
First oxygen then burning gas. The gas doesn't have a lot of pressure, so the flame can travel down the stream to the bottle. The oxygen sucks it out with it's high pressure. Also when turning off. First the burning gas. Then the oxygen. Basic safety.
Audela book says acetylene off first but I know from science class you don't leave a flame in oxygen as it is an accelerant. The pop is the flame jumping back into the torch. So why does a safety book contain incorrect information??
You're the reason why they install gas blockers on torches. Never ever shut off acetylene before oxygen. That little popping noise you hear is a small explosion. I use to have a supervisor that thought the same thing. Even claimed to have read it in a book he had at home. Still waiting to see that book
You're supposed to turn the oxygen off last so the gas can't ignite back in the tube by some chance. Setting it all up you turn oxygen up then the gas. Also your flame is far far bigger than it needs to be.

I learned how to use a cutting torch back in the 70s in High School.
We always cut off acetylene first to prevent the fire from getting big rapidly in case anyone was too close or we were In a confined space
well, this isn't how I was taught, I was just taught how the finished flame should look and that is it showing the 6 cones.

James… you should start by telling them how to set the gauges for whatever application and tip size you’re using.
on the next vid 👌
I would back the flame down a bit more so it doesn’t change as much in length when you pull the lever
There are multiple ways yes but then there's the right way !!!

I like to open both up just enough at the same time. With practice, you get it to light up just right most of the time. That way, i can avoid inhaling the black floating strands that you just put in the air by leaving the acetylene on in the beginning.
All right I've known a lot of people with cutting equipment like that and they don't ever do a soft carbonizing flame like that for cutting
In the field it’s common to set your flame hot and burn fast, 7-60 on the bottles.
In the backyard, I prefer 7/8 and 40.
I was taught to turn off the acetylene first, to prevent back fire in the hose.
We are taught to ignite via oxygen on befor the acetylen because theres like a swivel inside of the torch handle, which can break if acetylen is inited without oxygen. But thats mostly for welding. I like to say, 1/8 turn of oxygen 5 bars of pressure 1/4 turn of acetylen 0.8 bars of pressure.
I usually turn on the acetylene then put the oxygen in until the feathers get away from the pre-heat cones

Open both a quarter turn and light it off with a lil bang!
Nice looks good 😊
