How do you use oxy acetylene cutter?
Your oxygen level should be between 40-50 psi. Your oxygen vale should be turned on. Then, turn your acetylene vale a 1/3-1/5 turn. Turn your striker so that the torch is facing away from you. Adjust the acetylene valve so that the flame touches the tip of the torch but does not give off any black smoke.
How do you take Oxy Acetylene, also?
- Separately purge both fuel gas and oxygen lines.
- Open fuel gas valve 1/2 turn.
- Strikers can ignite flame.
- Increase fuel gas flow until flame leaves tip.
- Reduce flame until it reaches tip.
- Adjust the neutral flame by opening the oxygen valve.
- Make necessary adjustments by pressing the oxygen lever.
What determines the oxygen or acetylene pressure required for cutting? RULE OF THUMB, MULTI-HOLE CUTTING TIPS OXY/ACETYLENE. The recommended oxy/acetylene tip pressures for cutting vary depending on the size. If you don't have manufacturer setting information and are cutting less that 1 A 1/2 inches of steel, the acetylene regulator should be set at 10 psig and the oxygen regulator at 40 psig.
How does Oxy Acetylene cutting work?
Oxy-fuel cutting involves the chemical reaction of pure oxygen with steel to create iron oxide. Pure oxygen is then directed towards the heated area by a fine, high-pressure stream. The steel is oxidized, then blown away to create a cavity. The preheat and oxygen stream are then moved at constant speed to form continuous cuts.
Can you braze with only acetylene
Oxy acetylene is nearly twice as hot and takes slightly longer to braze applications. This virtually eliminates the risk of the metal being melted or distorted. The equipment of Air Acetylene is interchangeable.

Is acetylene bad to breathe?
The symptoms of acetylene inhalation include diz- ziness, headache, fatigue, nausea, vomiting, tachycardia and tachypnea [2]. Exposure to a high concentration of acetylene may result in a loss of consciousness and death [1] . Acetylene is a colorless gas commonly used for welding.
What happens when you mix oxygen and acetylene?
Needs only 10% mix of oxygen to ignite. It is an unstable gas, will violently decompose when in a pure state above 15 psi. What Is Acetylene? This means if acetylene reaches 30 psi in a free state, it can explode by itself without a spark or flame being present.
How much does it cost to fill an oxygen acetylene tank?
Expect to pay around $200 - $300 depending on size of tanks, level of fill, brand and size of torches. If you do got the CL route, make sure they are private cylinders (meaning no company markings on the cylinders), when it comes time to fill, they usually just exchange them.
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.
What size oxy acetylene tanks should I get?
The rule of thumb is you should use acetylene at a rate that is not greater than 15% of the tank in an hour. So if you use acetylene at a constant rate, you should use a tip small enough to get 7 hours use out of the tank. If you really need to crank a bigger flame for a moment, that is not a problem.
How do you turn off an oxygen acetylene torch?
Close the acetylene hand valve on the torch, then the oxygen valve. This extinguishes the flame and eliminates the soot. 3. Open the hand valves on the torch, bleed lines, close hand valves on torch, turn regulator adjusting screws all the way out".
How hot is an acetylene torch?
3200 °C to 3500 °C
Can aluminum be welded with oxy acetylene?
Oxy-acetylene torches can be used for a variety of processes, and is one of the many things that can be used to weld aluminum. Other welding techniques that are effective for aluminum include TIG (tungsten inert gas) welding and MIG (metal inert gas) welding.
What metals can be welded with oxy acetylene?
Low-carbon steel, low-alloy steel (e.g., 4130), cast steel, and wrought iron are easily welded with the oxy-acetylene flame. Low-carbon and low-alloy steels are the ferrous materials that are gas welded most frequently.
Is oxy acetylene welding still used?
Oxy-acetylene is one of the oldest and most universally used welding processes. Oxy-acetylene welding has become less popular in industrial applications over the years, but is still used extensively in field and shop work.
Which material Cannot be cut by the oxyfuel process?
Oxy-fuel cutting cannot cut non-ferrous metals such as aluminum, stainless, brass or copper. Elements such as chromium, nickel, molybdenum inhibit the ability to cut steel with the oxy-fuel process.
What materials can oxy fuel cut?
Oxy-fuel cutting is a thermal cutting process that uses oxygen and fuel gas (such as acetylene, propane, MAPP, propylene and natural gas) to cut through materials.
Why Acetylene is used in gas welding?
Acetylene produces a flame temperature of ~3100 degree Celsius along with oxygen. This high flame temperature makes acetylene a suitable choice for gas welding steel. 2. Welding: When burned in oxygen, acetylene produces a reducing zone, which easily cleans the metal surface.
Why gas cutting is not possible in stainless steel?
Similarly in stainless steels, Chromia layer protects the surface. Similarly in stainless steels, Chromia layer protects the surface. Although it is not impossible to cut, a lot of reducing gas and heat energy will be used to cut it makig the process uneconomical and defeating the purpose of a fast clean cut.
How much pressure is in a full acetylene cylinder?
A full acetylene cylinder which has a pressure of 250 psi at 700F (1725 kPa at 20 C) will have a pressure of 315 psi at 900F (2175 kPa at 310C) and a pressure of 190 psi at 500 F (1300 kPa at 90C). You must always take temperature into account when estimating how much acetylene the cylinder contains.
How do I know when my acetylene tank is empty?
Look on your cylinder; there is a tare weight stamped. Weigh the cylinder and subtract the tare weight. Acetylene is 14.5 cu. ft. /#, so you can find out how much you have.
