How Do You Use Oxy Acetylene Cutter?
Do you turn on oxygen or acetylene first? 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.
? Oxy-acetylene torches can easily cut through ferrous materials in excess of 200 mm (8 inches).
Oxygen lances are used in scrapping operations and cut sections thicker than 200 mm (8 inches).
? Oxy-fuel torches are normally used for cutting only ferrous metals or those containing iron, such as carbon steel.
For the most part, they are not used for cutting cast iron, aluminum or stainless steel.
How Do You Use Oxy Acetylene Cutter? – Related Questions
How many types of cutting nozzles are there?
There are three main globally recognized and frequently used nozzles. They are supplied in different sizes, material, bore diameters, and pressure tolerance ability. This attracts a different gas cutting nozzle price on each piece. In this section, this article sheds light on the three main gas cutting nozzles.
What should my oxy acetylene regulators be set at?
The recommended setting for multi-hole cutting using oxy acetylene is the oxygen regulator at 40 psig with the acetylene regulator setting at 10 psig.
What does a plasma cutter use to cut?
Plasma cutting is a process that cuts through electrically conductive materials by means of an accelerated jet of hot plasma. Typical materials cut with a plasma torch include steel, stainless steel, aluminum, brass and copper, although other conductive metals may be cut as well.
Do you use more oxygen or acetylene?
For the maximum flame temperature in oxygen, the ratio of the volume of oxygen to fuel gas are 1,2 to 1 for acetylene and 4.3 to 1 for propane. So, there is far more oxygen being consumed when using Propane. Despite Propane being less expensive than acetylene, this is counteracted by the higher oxygen consumption.
What happens when you lay an acetylene tank 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.
Does acetylene burn without oxygen?
Decomposition is a chemical reaction whereby acetylene breaks down into its constituent elements, carbon and hydrogen. This reaction gives out a great deal of heat, which can cause the gas to effectively ignite without the presence of air or oxygen.
What is the difference between an oxygen and acetylene regulator?
The acetylene regulator design is generally the same as that of the oxygen regulator, but will not withstand such high pressures. The high pressure gauge, on the inlet side of the regulator, is graduated from 0 to 500 psi (3447.5 kPa).
What pressure should I set my oxygen and acetylene?
The 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
What pressure should I set my cutting torch?
CAUTION: Never exceed 15 pounds per square inch (psi) when using Acetylene.
NOTE: Most torch mixers use a “positive” design that requires fuel gas pressures set between 5-15 psi for cutting applications.
How thick can a cutting torch cut?
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.
How thick can a plasma cutter cut?
about 1 inch
Plasma cutters are used to perform cutting and gouging operations, with the average hand-held system capable of cutting a maximum metal thickness of about 1 inch.
Can Aluminium cut flames?
Unfortunately, while flame cutting is a cheap, efficient option for working with ferrous metals such as iron and steel, it is nearly impossible to effectively use with aluminum or stainless steel.
Can a plasma cutter cut aluminum?
Plasma cutting can be performed on any type of conductive metal – mild steel, aluminum and stainless are some examples.
Plasma cutting, however, does not rely on oxidation to work, and thus it can cut aluminum, stainless and any other conductive material.
What are the three types of flames?
There are three types of flames natural flame, carburizing flame and oxidizing flame.

Why oxygen is used in gas cutting?
Basically, a mixture of oxygen and the fuel gas is used to preheat the metal to its ‘ignition’ temperature which, for steel, is 700°C – 900°C (bright red heat) but well below its melting point.
The oxygen jet blows away the slag enabling the jet to pierce through the material and continue to cut through the material.
