How To Use Oxy Acetylene Torch: Basics For Beginners

Slightly open the valve for acetylene on the cutting torch. Make sure that it does not exceed a half-turn. Use a flint striker or spark lighter to ignite the acetylene gas flowing out of the torch’s nozzle. Soot or black smoke may come out once it is lit up, which is considered normal. How to Use an Acetylene Torch. To use an acetylene torch for cutting after properly setting up the equipment, conducting a leak test, and lighting up the torch, you must first pre-heat the metal in preparation for cutting. Do not press the torch lever when doing so, as the flame present is only hot enough for pre-heating, not cutting.

Does the thought of using an oxy acetylene cutting torch intimidate you? We feel you. After all, dealing with two tanks that are at risk of catching fire as you work sounds risky. You would rather have all your body parts firmly attached as you work, right? If you have the right settings for the entire system, you can safely use an oxy acetylene torch for all your projects.

Not only that, you must light the torch and shut it off correctly. Yes, there are proper ways to do all that. We carefully reviewed a bunch of products, and these are our recommendations. Before you set up your cutting torch, you must first understand how it works so that you can handle it properly. Not only that, this will allow you to get a cut how to motivate a college student good quality, which is only possible if done correctly.

For more serious cutting jobs, we do recommend the use of a plasma cutterthough. An oxy acetylene cutting torch allows oxygen to mix with acetylene to combust and produce a flame that has a temperature exceeding C. This kind of flame is the only one hot enough to cut through mild steel, specifically any kind of steel that only has a maximum of 0.

The cutting torch pre-heats steel for it to reach that temperature; a cherry red color on the steel will be the sign that it has been adequately preheated.

When oxygen from the cutting torch reaches the unprotected steel, an exothermic reaction occurs that causes it to form oxidized liquid steel or slag. Because steel has a higher melting point, this slag that formed can easily be blown away by oxygen. This then reveals the solid steel that has not been oxidized. The exothermic reaction that occurs is continuous as long as the cutting torch is lit up and the flame hits the steel.

This constant reaction prevents a crust from forming on the steel, which immediately occurs if the protection against oxygen is still present on the steel. Because there is no crust that forms, the oxygen from the cutting torch can now penetrate the exposed solid steel and cut through it. Due to the acetylene present, the flame produced by the cutting torch is the highest among all how to use an acetylene cutting torch cutting processes.

This means you can make cuts much faster and of better quality than the how to repair an oil leak methods. Large cylinder tanks. With all these components, setting up an oxy acetylene torch can be an overwhelming experience. While we admit that setting it up is not a straightforward affair, it is still doable even by beginners. Setting up such a system is pretty standard, but you must first check for any unique instructions the manufacturer of your cutting torch may have.

After setting up, you still need to do some checks before attempting to light your cutting torch. Make sure that the regulators are facing away from you when you do the following:. After successfully doing a leak test, you can now light up your oxy acetylene cutting torch following the instructions of the manufacturer. Because of the gases involved, lighting up a cutting torch is done differently.

Unlike other torches, a cutting torch will not produce a flame with just a push of the button. You should only use a flint striker to light a cutting torch because using smaller lighting devices, such as a match or lighter, are too small and will put you at risk of burning your hands as you light up the cutting torch.

Also, you must make sure that the tip of your cutting torch is facing away from you, other people, and any flammable objects. But if your cutting torch has its own ignition device, skip the above steps and follow the instructions given. Because there is also no knob or button present on the torch to stop how to change html font color flame, you must manually shut down your oxy acetylene cutting torch by cutting off the gas being supplied.

If you are not yet aware, there is a seemingly never-ending debate about which gas supply to switch off first — oxygen followed by acetylene or acetylene then oxygen. While both methods are considered correct, manufacturers generally advocate shutting off the oxygen valve first before acetylene.

This method allows the acetylene still flowing to blow off the soot that settles in the crevices of your torch; any soot present can affect the seal of the gas valves and cause a leak. Not only that, but this order also allows you to conduct a leak test before cutting off the gas supply. Once you cut off the oxygen supply then acetylene, the presence of a small flame despite no gas flowing to the torch will indicate a leak.

Early leak detection helps prevent an explosion. Another advantage of cutting off the oxygen supply first is how to join pakistan air force mini flashbacks are less likely to occur.

Despite most cutting torches having protective features against it, flashbacks can still happen. Mini flashbacks occur in the form of a loud pop or bang. While how to use an acetylene cutting torch considered harmless, mini flashbacks can still cause accidents. If you are done with your work and need to return your equipment to its storage, you must follow the following steps:. When storing the oxygen and acetylene tanks, make sure to keep it in a dry and airy location far away from any flammable objects.

Always keep them in a vertical position. Have you ever attempted to cut cast iron using an ordinary blowtorch? If so, you what is cardio kickboxing class have realized that it is a futile effort.

But if you are using a cutting torch to do so, the result will be different. Because an oxy-acetylene torch has the highest flame temperature present, it can easily cut through even steel that is at least mm thick.

But when it comes to cutting cast iron, it is also possible but it will not give you a clean cut and is a bit harder to do. Preheating the cast iron is crucial to cut through it, and this is done by setting the cutting torch so that it produces a carburizing flame, instead of a neutral flame, and with the highest possible temperature.

This type of flame offers better preheating to the cast iron and also stops oxides from rapidly forming. Preheating should be done from the top all the way to the bottom and with more acetylene so that the heat will deeply penetrate the cast iron. Once it is sufficiently preheated, make small semicircles around the preheated line to melt the iron. Finally, use the oxygen jet to blow off the molten iron and cut through it.

You may need to use flux to help you make the cut. Because of the complicated process, using an oxy acetylene cutting torch to cut through cast iron is not often used. In fact, there are other methods specially developed for this purpose.

Are you wondering if you need to buy separate welding equipment if you already have a cutting torch and need to do some welding? If so, we have good news — you can also use your oxy acetylene cutting torch for your welding needs.

In fact, this process is known as oxy acetylene welding. Basically, the metals are placed side by side, with a small gap present between them, and are melted together by the oxy-acetylene flame.

When they cool down, the how to make sweet trees step by step sections are already bonded to form a weld seam. Oxy acetylene welding can be used if quickly joining metals together is your only concern because the weld seam formed is not as neat as the ones created by other welding methods. A neutral flame is also used for welding using a cutting how to calculate proceeds from sale of equipment, but you need to move your torch in a circular manner so that the metals will melt and pool towards the small gap present between them.

While the weld seam formed using this method is strong enough, you can also add filler material using a rod to increase its strength. An oxy acetylene cutting torch, contrary to its name, is not only used for cutting.

You can also use it in different ways, making it such a versatile tool that you must have in your workshop. Your email address will not be published.

As a welder, you must know how to use oxy-acetylene torch to upgrade your skill in welding. For welding or cutting, using Oxy-fuel is not only a common method to apply in a workshop but more than it.

This equipment is super easy to use and minimizes the welding cost dramatically. To become a perfectionist in regular or special cutting and welding, you must know some tips. Also, these tips will help you to make your welding or cutting job easier, even in awkward places or odd angles. After knowing how to use oxy acetylene torch, you can go for some serious or occasional metalwork. This process is simple and that is lighting, adjusting, using, and shutting down the torch.

The oxy-acetylene torch is the key to knowing the Mystery of a simple flame that is produced with a blend of oxygen and acetylene. Remember, all the components make this torch more effective to heat, weld, braze, and cut like butter without making any problem. Burning acetylene gas is the key point to produce much heat or energy and the temperature could be degrees.

Along with the basic torch outfit, this single piece of equipment is popular in the welder community. So, we are going to address some steps, including safety issues to ensure proper use of an oxy-acetylene torch. There are some key safety points you must follow to use this torch. Some of these are given below. For the better use, you know everything about equipment and connections. There are two hoses for the connection. One is for acetylene and another one is for oxygen that comes with shutoff valves.

Some torch offers a mixing valve that omits the use of the oxygen shutoff valve. Finally, it will get out to the tip called the cutting tip. But the oxygen needs to flow through two circuits. In this chamber, oxygen will be mixed with the acetylene gas. You can easily swap and change the base to cut metal based on its thickness.

For the quality cut, we suggest you use the right tip. Both cylinders have valves. According to the cutting tip size, adjust the regulator recommended by the manufacturer.

In the beginning, 20 psi for oxygen and 5 psi for acetylene will be perfect. This ratio produces a flame for medium cutting. Take a striker and ignite the torch. Before you do it, open the acetylene valve very slightly. Before starting the process, close the valve if the flame is larger.

The flame should be small. Now slowly open the valve that increases the flame size. Remember small movement of the valve can result in massive. A larger flame is suitable for thin material and a small flame for thicker material. After adjustment of the acetylene valve add oxygen using the mixing valve.

Start to mix it when valves are fully closed. Full open mixing valve slowly until you get the neutral flame. Once the flame is adjusted, then the torch is ready to roll. Keep everything in position to avoid damage and cut safely. Wrong positioning can ignite other materials.

Before the cutting, the flame starts to heat the metal that is called preheating. After a few seconds, the flame will go through the metal and the burning procedure will start. For the best cutting experience in the easiest way, you should start it from the edge of the metal. You better position the torch and start to cut when the area shades of red or orange.

Now ensure the main oxygen flow. Squeeze the lever to do that. Because of this action, the metal starts to cut. When you notice the flame is cutting the metal, then begin to move the torch to get the job done following the right coordination.

After finishing the cutting session, close all the valves. Using oxy-acetylene is not only important to complete the welding task easily, but also safe to use. Knowing more about them using process and tips means you can easily use this portable torch without facing any problem. All the details that I have discussed earlier in this guideline can be more useful for you that can increase your welding and cutting skills on the metal.
