An oxy acetylene torch is an affordable and versatile tool used by many people to estrus, weld, solder, and cutting metal. It uses extreme heat to function, and setting it upwards properly is one of the virtually of import steps in using it safely. Using pressure-reducing regulators, connecting gas supplies, and safely lighting the torch flame are all essential parts of learning how to use an oxy acetylene torch.

  1. 1

    Fasten oxygen and acetylene cylinders in an upright position. If you have a cylinder cart, identify both the oxygen and acetylene cylinders into it. If not, they should be deeply fastened with a chain to a workbench, a wall, or a mail service. Cylinders should not be able to exist knocked or pulled over.[1]

    • Cylinders should simply be used and stored in the vertical position.

  2. ii

    Clean the valve outlet of accumulated grit or dirt. Stand so the outlet is facing away from your body and open up the valve a 1/iv turn, very speedily, and so close information technology. This volition articulate out any grit or clay that may have settled in the valve. It needs to be cleaned out otherwise the droppings might get into other parts of the torch and crusade it to malfunction.[ii]

    • Warning: never clear a fuel gas cylinder nearly other welding piece of work that is in progress or nearly sparks or flames.

  3. 3

    Connect the oxygen and acetylene regulators to their cylinders. The regulators let you lot encounter how much pressure y'all're using while working and are essential to safely starting and operating an oxy acetylene torch.[3]

    • If the regulator and cylinder have dissimilar threads (significant they don't fit into each other), yous will demand to use an adaptor, which can be purchased at whatsoever local hardware shop.

  4. 4

    Tighten the nuts of the regulator connections with a wrench. Don't presume because you have turned the nut as far as you can with your paw that it is tight enough. Use a wrench with a fixed opening (rather than an adaptable wrench) that is designed specifically for welding tools. Y'all can buy these from a hardware store or a specific apparatus supplier.[4]

    • If you ever need to make an adjustment afterwards the cylinder has been opened and used, make sure to close the cylinder valve before tightening the nut over again.

  5. v

    Rotate the pressure-adjusting screw to the left until it turns freely. Do this for each regulator. The valve in the regulator needs to be airtight before cylinder pressure level is admitted. Turning the pressure-adjusting screw counter-clockwise removes the pressure from the spring in the regulator.[5]

    • When the spiral turns freely, you should be able to just tap it with your finger and see it motility, rather than having to apply pressure level.

  6. 6

    Open the oxygen and the acetylene valves very slowly. Make sure yous can see the cylinder-force per unit area gauges, just don't stand direct in front of the valves. Open up the valves slowly to protect yourself and your motorcar from any potential combustion.

    • Open the oxygen valve very slightly at outset and pause until the pressure judge paw isn't moving any more than earlier moving on to open the valve fully.
    • The acetylene valve should never be opened more than 1 and 1/ii turns.[vi]

  7. 7

    Go out the wrench on the acetylene valve while information technology is open. Basically, if y'all accept an emergency you won't accept to waste fourth dimension looking for an appropriate wrench. If it'south on there, yous'll be able to close the cylinder valve right abroad.[7]

    • In general, it's smart to work in an area where you can reach all your tools without having to search for them. Think ahead when you are starting a projection and bring your tools to your workspace before beginning.

  1. one

    Utilise a hose and hose connections specific to welding and cutting. Oxygen hoses will have a green cover, while acetylene hoses will have a crimson cover. Never interchange these hoses equally they are meant for different substances. If 1 of your hoses accept cleaved, supercede it—don't apply tape of any sort to try and patch the hole.[8]

    • A hose with a natural rubber liner is okay for acetylene service.

  2. 2

    Practise non apply whatever oil or grease on the hoses. All the connections from the gas supplies to the torch are metal-to-metal, and they don't require lubricants or sealants. Similarly, don't apply any pipage-plumbing equipment tools to connect the hoses to the torch.[9]

    • Don't forcefulness connections—if the threads don't run together easily by hand, either the threads are damaged or the parts aren't meant to go together.

  3. iii

    Attach the oxygen hose to the oxygen regulator and to the torch. The torch should have identifying marks on the body or the handle showing where the hose should be connected. Nigh torches have two oxygen connections because 1 is used for the cutting jet and 1 is used for the preheat flames. If at that place isn't an adaptor on the torch that unites these ii connections, you lot will need to utilise 2 oxygen hoses, 2 regulators, and two oxygen tanks.[10]

    • Near new oxy acetylene torches come up with congenital in adapters, but double-check with the manufacturer'south instructions to be safety.

  4. 4

    Connect the acetylene hose to the acetylene regulator and to the torch. Sometimes the torch doesn't specify which connection is for the acetylene, though the oxygen will be clearly marked. Whichever connection is not for the oxygen is for the acetylene.[11]

    • Double cheque your connections earlier moving on to brand sure everything is hooked up to the right identify.

  5. 5

    Tighten the hose connections with a wrench. Don't trust your hand force to tighten these connections for you. Utilise a not-adjustable wrench to securely fasten both the oxygen and acetylene hoses to the torch.[12]

    • Having tight connections is extremely important considering they will keep both the oxygen and acetylene from leaking.

    6. Ad

  1. 1

    Shut both torch valves. For the oxygen, plow the force per unit area-adjusting screw on the regulator until the gauge reads about 25 psi. For the acetylene, turn the force per unit area-adjusting screw on the regulator until the gauge reads nearly x psi.[thirteen]

    • Information technology is very important to test for leaks before starting your projection. Leaks tin can cause impairment to you or your surroundings and may lead to spontaneous combustion of the cylinders.

  2. 2

    Apply a leak-test solution with a brush. Apply the solution to the cylinder valves, the cylinder and regulator connections, and all the hose connections. You lot can either buy a solution from the store for this specific purpose, or you tin can deliquesce Ivory soap in h2o to brand a thin paste for the same results.[14]

    • Any piece of work brush yous have on paw will do; just make certain information technology hasn't been compromised past oil or gas.

  3. 3

    Check the leak-test solution for bubbles. Bubbling indicate that either oxygen or acetylene is coming through the connectors and the connexion needs to be tightened or reattached completely. The bubbling won't exist big, like in a pot of boiling h2o; rather, they will be pocket-sized and volition make the surface of the testing solution look uneven.[15]

    • Give the solution 1-2 minutes to sit before checking for leaks.

  4. 4

    Release all pressure from whatsoever system that has a leak. Reattach or retighten every bit needed, and apply the leak-examination solution a 2nd time to test the torch for leaks again. Later on completing the testing, make sure to turn off both the oxygen and acetylene.[16]

    • If after you've tested and refastened any leaking areas y'all are still seeing bubbling, that may indicate you take a leaky hose and need to get a new one before moving on with your projection.

    5. Advertizing

  1. i

    Turn the oxygen regulator pressure-adjusting screw. Slowly do this until y'all reach the desired pressure. The pressure will be indicated on the delivery-pressure gauge. Then you will shut the torch oxygen valve. If you are using a cutting torch, open only the torch cut oxygen valve. If you are using a cutting attachment, open up the oxygen valve on the torch handle and the cutting oxygen valve on the attachment.[17]

    • Don't set the pressure higher than what the equipment manufacturer recommends.

  2. ii

    Adjust the acetylene adjuster spiral to the desired working pressure level. Do not exceed 15 psi. Close the acetylene valve immediately after you obtain the correct pressure. Yous shouldn't open up the valve more than 1 full turn.[xviii]

    • If you open the valve besides fast or besides far, you may cause the canister to combust.

  3. 3

    Practise not release acetylene or other gasses near sources of ignition. Also, make certain yous are working in a well-ventilated area. It is appropriate to keep a fire extinguisher in your workspace in case in that location are any explosions or emergencies.[19]

    • Heating, welding, and cutting cause fume and fumes that are bad to breathe in and that can irritate the skin.

    4. Advertisement

  1. 1

    Check the manufacturer'due south instructions for the torch before beginning. Though most torches follow the same operating procedure, the manufacturer'southward instructions may have helpful tips or warnings that are specific to your torch. Read it thoroughly before following steps or tips from any other sources.[20]

    • You can as well search the manufacturer online to bank check out more information regarding your tool. A lot of sites have community forums where people post tips and stories about their experiences that you can larn from.

  2. two

    Open the torch acetylene valve one/2 turn and calorie-free the flame. Utilize a friction lighter rather than a friction match for this step. A friction lighter is as well called a torch striker, and these tin exist found at hardware stores. Y'all volition see a flame coming out of your torch. If for some reason there isn't a flame, turn off the acetylene valve and check your connections.

    • Think to not have the oxygen gas flowing when y'all go to lite the torch.[21]

  3. 3

    Reduce the acetylene flow by adjusting the torch acetylene valve. The flame should start to produce blackness smoke around the edges. In one case the blackness smoke appears, start to increase the acetylene menses back up again just plenty to get rid of the black smoke. The flame should nevertheless be attached to the tip (information technology shouldn't appear as though it has "jumped abroad" from it).

    • The lighting procedure should result in a neutral flame, which is blue in color and which does not make a hissing sound.[22]

  4. 4

    End working if the flame suddenly goes out. This is chosen "backfire" and can happen it the torch comes into direct contact with the metal. If this happens, go ahead and relight the torch once again right away. If backfire occurs repeatedly without contact with the piece of work, it may be due to wrong operating pressures or a loose nozzle in the torch. In this case, check the operating pressures and take a look at the torch to brand sure everything is connected properly.[23]

    • If in doubtfulness, plow off the gasses and check your machine over before proceeding.

  5. 5

    Turn off the torch if there is flashback. Flashback is when in that location is a pronounced hissing or squealing dissonance. This ways at that place is something wrong with the torch or with the prepare. After turning off the torch and investigating the cause, wait until the torch has cooled before attempting to light it once more.[24]

    • If your torch keeps experiencing flashback, there may exist a damaged piece that needs to exist returned or replaced.

Add together New Question

  • Question

    Why is the head of an oxy acetylene torch made of brass?

    Community Answer

    Because it is a corrosion resistant metal that will not create sparks when struck against other substances.

  • Question

    Which tip should I use to oestrus the metallic up?

    Community Answer

    There is a tip called a rose bud that produces a large surface area to heat metals. A brazing tip can work on smaller areas.

  • Question

    How many gauges are needed on the acetylene bottle?

    Community Answer

    Two. A Cylinder Pressure level Judge and a Working Pressure Approximate. The CPG will show about 200psi on a full acetylene bottle and decrease every bit it is used. The WPG indicates the gas pressure to the torch and is set by the regulator.

  • Question

    What size tip do I need for cut thick metal in one-half?

    Community Answer

    Use a larger tip for cutting thick metal.

  • Question

    How practise I terminate black smoke from happening when I light an oxy acetylene torch?

    Community Answer

    You can't, considering it's a carbon gas. Do not try lighting with some oxy considering that is an explosive mixture.

  • Question

    Can I lay the gas tank down while it is being used?

    Community Answer

    You could lay the oxygen bottle downwards, merely never lay the acetylene canteen down. The acetylene bottle contains acetone, which helps stabilize the acetylene. Laying the bottle downwardly could lead to venting the acetone. A general rule of thumb is don't lay either bottle downwards.

  • Question

    How do I ready upward the regulator?

    Community Answer

    The acetylene regulator should exist betwixt 5-7 psi.

  • Question

    What is the safety device fitted to the regulator?

    Community Answer

    Information technology is a back-menstruum preventer. It keeps the acetylene from mixing in the hoses and tanks with the oxygen and vice versa.

  • Question

    Why exercise the torches keep going out?

    Community Answer

    The piece of work is dissipating oestrus faster than the torch is producing information technology. Turn upward the torch or use a larger tip.

  • Question

    Can you provide a list of procedures for adjusting an oxyacetylene torch for brazing?

    Sarah Battilana

    Sarah Battilana

    Community Answer

    A dissimilar mechanism chosen "capillary action" is used for brazing. To achieve compatible capillary activity, both parts must be evenly heated before adding rod. Preheating conducts heat through the joint and brings both pieces to the right brazing temperature. The torch must be kept in motion to evenly distribute heat and should be kept further away than traditionally to keep sections from overheating.
