The third open valve in the torch, first acetylene after that you can open oxygen valve. If the gas has out from nozzle you can use lighter and light the torch. Types of Oxy-Acetylene Welding Flames:
What pressure should oxygen and acetylene be set at?
3 to 5psiThe gas pressures should be set at 3 to 5psi for Acetylene, and 20 to 30psi for the oxygen, but when you squeeze the oxygen lever after the initial flame adjustment of the preheat flames to neutral just to a point where the feather disappears,the oxygen cutting stream should be visible and at least 4 inches in length ...18-May-2005
What PSI should acetylene never be above?
15 psiNever use acetylene at pressures above 15 psi. Using acetylene at pressures in excess of 15 psi gauge pressure (or about 30 psi absolute pressure) is a hazardous practice.
What is the normal working pressure for acetylene?
The working pressure of acetylene equipment is critical: Acetylene pressure must not exceed 0.62 bar (9psi) unless equipment has been specifically designed for it.
What happens to acetylene above 15 psi?
Acetylene will not explode under low pressure at normal temperatures. However, it becomes unstable and spontaneously combustible when compressed to a pressure over 15 psi. Beyond 29.4 psi, it becomes self explosive, and a slight shock may cause it to explode even in the absence of air or oxygen.26-Apr-2004
What is the PSI of a full oxygen tank?
about 2000 psiA full cylinder will read about 2000 psi (pounds per square inch). the gauge reaches the flow rate your doctor prescribed. the regulator. Secure oxygen cylinders in your vehicle so they do not roll or bump against other cylinders or objects.
What pressure does acetylene become explosive?
15 psiAcetylene can also be explosive if the regulated pressure exceeds 15 psi (Pounds per Square Inch). Mixing acetylene with air, liquefying, compressing or heating the gas can also cause potential hazards.30-Dec-2019
What pressure should a cutting torch be set at?
between 5-15 psiNOTE: Most torch mixers use a "positive" design that requires fuel gas pressures set between 5-15 psi for cutting applications. However, some torches use an injector (low pressure) mixer design that only requires ¼ - 2 psi of alternate fuel gas.
What do you turn off first oxygen or acetylene?
We recommend closing the oxygen valve first whenever turning off an oxy-fuel torch system especially when Acetylene is fuel. This is only part, but a very important part, of the complete safe operating procedure recommended for torches by Harris.
Is it safe to lay an acetylene bottle on its side?
Do not lay acetylene cylinders on their sides. If an acetylene tank has accidentally been left on its side, set it upright for at least one hour before it is used. Do not try to refill a cylinder or mix gases in a cylinder.
What is the best way to set the oxygen pressure for cutting?
What is the best way to set the oxygen pressure for cutting? Make sure the oxygen cylinder is secure and open the valve all the way. What metals can be cut with the oxyfuel gas process?
What is the maximum pressure that should be used with a gauge whose highest number is 400 psig?
If the highest pressure marked on the face of an oxygen pressure gauge is 400 psig, it is recommended that this gauge should not be used at pressures above 200 psig. To avoid possible burns, pliers or tongs should be used to pick up metal in the welding shop.
What is an oxy acetylene 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. Using an oxy-acetylene torch can be more versatile when you’ll follow some steps and tips.
How long does it take for a torch to burn metal?
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.
Can you use oxy fuel in welding?
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.
What temperature is acetylene?
Oxy-Acetylene Torch Use and Safety: Burning acetylene gas is the key point to produce much heat or energy and the temperature could be 5620 degrees. So, this torch may be easy to use, but it can burn and explode if you can’t handle it properly. Along with the basic torch outfit, this single piece of equipment is popular in the welder community.
How to cut metal with a torch?
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.
Is oxygen dangerous to put in a cylinder?
Another thing you need to care about and that is oxygen. It can turn into a dangerous element and react immediately with grease and oil. So, don’t put such an element near the oxygen cylinder. Don’t try to operate another element and that is acetylene near or above around 15 psi.
What to do if torch rig is not set up?
If the torch rig is not set up then consult with an expert who can guide you to set this thing correctly. Ensure that all the components are working perfectly, including the regulator. Look for any leaks in the system, otherwise, it can be dangerous. Check the hose and ensure it’s in good shape.
What pressure should oxygen be in a torch?
For cutting everything is different and the oxygen pressure should be about 25 PSI.
How many holes do you need to clean a cutting torch tip?
The small holes are for the high pressure oxygen that blows the slag away. All 7 holes must be clean for the cutting torch to work efficiently.
Is gas a fuel?
Gas is a fuel gas, because you don’t have to use acetylene, although you’re nuts if you don’t. If I’m going to set this regulator, I want the gas open, because I want to set the pressure while there’s actually gas coming out. So I’ve got that open. Well let’s take a look a little closer at the gauge.
Do all new torch bodies have check valves?
There should be check valves in the torch body. All new ones have check valves. One of the reasons I make sure my oxygen is always higher than my acetylene is so that we do not get into a situation where acetylene could actually go back into the oxygen line. Then it could burn inside the line.
Does acetylene gas explode?
You’ll notice that the acetylene gas has a mark around the fitting. This one does not on oxygen. That’s because this is left hand thread. They don’t want you mixing these things up, because here again if you’re running acetylene, which is just full of carbon, through an oxygen line, it could explode.
