Acetylene gas torch

What is an oxy-acetylene torch used for? Oxy-acetylene torches using the gas cutting method are one of the most popular tools for separating metals with low-alloy and low-carbon properties.

What is the difference between acetylene and oxy acetylene?

A major difference between the two setups is how acetylene is combusted. An oxygen/acetylene system requires a cylinder of compressed acetylene gas as well as a cylinder of compressed high-purity oxygen. It combines these gases to get an intense flame temperature.

Can you use just acetylene without oxygen?

Without oxygen, acetylene does not burn nearly as hot as we need it to. Adding oxygen to this flame gets us that nice blue cutting flame.

Which gas is used in oxy-acetylene torch?

Oxyacetylene welding, commonly referred to as gas welding, is a process which relies on combustion of oxygen and acetylene. When mixed together in correct proportions within a hand-held torch or blowpipe, a relatively hot flame is produced with a temperature of about 3,200 deg.

Which is better acetylene or propane?

Acetylene releases almost 40% of its heat in the inner flame cone. Therefore, acetylene is better for cutting than propane. While temperature wise acetylene is hotter than propane the fact is that people are using propane for cutting incorrectly.

Is acetylene harmful to humans?

► Acetylene can affect you when inhaled. ► Contact with the liquid can cause frostbite. ► Exposure can cause headache, dizziness, lightheadedness, and passing out.

Can you cut with just acetylene?

That flame can be used for cutting and welding (although it's not as efficient a way to weld metal as electric arc welding). Acetylene will burn by itself when it combines with atmospheric oxygen, but adding pressurized oxygen makes for a much cleaner, almost focused flame.

Why acetylene is not used as fuel?

Although acetylene gas has a potential of being an alternative fuel in internal combustion engines in terms of its high combustion temperature and rate, rapid ignition and being economical, it has not been widely used so far due to difficulties in its storage and use.

Which is cheaper propane or acetylene?

Despite propane being less expensive than acetylene, this is counteracted by the higher oxygen consumption.

Why can't you lay acetylene on its side?

Acetylene cylinders must not be placed on their sides, since the acetone and binders will have dislodged. The result may be formation of an acetylene "pocket" that is subject to polymerization and the possibility that liquid acetone will be released into the regulator.

What is the 1/7 acetylene rule?

The 1/7th rule refers to the flow rate at which an operator dispenses the gas from the cylinder. For common uses like welding, cutting and allied processes it is recommended to flow no more than 1/7th of the cylinder's total contents at a time at a regulated pressure that does not exceed 15 pounds per square inch.

Do you turn on acetylene or oxygen first?

You always turn on acetylene first, light it, and set the flame to a minimum. THEN you turn on the oxygen, and adjust the flame as required to correct it for either welding or cutting. You always turn OFF the Oxygen first, and then the acetylene.

What are the 3 types of flames?

There are three types of flames natural flame, carburizing flame and oxidizing flame. Natural flame has synchronized mixture of fuel and oxygen, carburizing flame has more fuel and oxidizing flame has more oxygen. Different material used different flames according to weld condition.

Which gas is used in gas torch?

A propane torch is a tool normally used for the application of flame or heat which uses propane, a hydrocarbon gas, for its fuel and ambient air as its combustion medium. Propane is one of a group of by-products of the natural gas and petroleum industries known as liquefied petroleum gas (LPG).

Which color is used for acetylene?

Acetylene gas cylinder colour code is Claret Fire and explosion hazards are greater than LPG but it is slightly lighter than air and less likely to collect in ducts and drains.

When should acetylene never be used?

Never use acetylene at pressures above 15 psig, as it becomes unstable above that pressure. Purge the system before use each day by bleeding off the hoses one at a time.

What burns hotter oxygen or acetylene?

MAPP burns at 2925°C (with oxygen), acetylene at 3160°C (with oxygen). That means acetylene burns hotter. Why does a colder gas mix less with ambient air in the open atmosphere than a warmer gas?

What can be used instead of acetylene?

Oxy Propane Propane is the easiest fuel gas alternative to Acetylene to obtain and is normally supplied in cylinders on a Deposit basis, rather than rented (as is usually the case with Acetylene). For most users, Propane works out cheaper, especially for infrequent users of Oxygen + Fuel kits.

Which is safer propane or acetylene?

Acetylene will ignite at mixtures from 2.5 percent to 82 percent, while the range for propane is 2.1 percent to 9.5 percent. Based off of these numbers, it's easy to argue that propane is much safer to use than acetylene. However, keep in mind that these are both flammable gases, and both need to be handled with care.
