How do you cut an oxy acetylene torch for cutting

The recommended setting for multi-hole cutting is the oxygen regulator at 40 psig with the acetylene regulator setting at 10 psig.

What setting do you use to cut oxy acetylene?

The recommended setting for multi-hole cutting is the oxygen regulator at 40 psig with the acetylene regulator setting at 10 psig.

What pressure should oxygen and acetylene be set at for cutting?

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 …

How far should the cutting preheat flame be from the base metal when cutting?

The preheating flames should be about 1/16″-1/8″ (1.6 mm-3.2 mm) above the metal. 8. Squeeze the oxygen cutting valve when the metal turns an orange-red color (1500°F/816°C).

How thick can an oxy acetylene torch cut?

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).

What angle do you hold a cutting torch?

At the end of the cut, roll the torch outward to help ensure a clean sever. 11. Lighting alternate fuels – If you have trouble lighting the torch, hold it against the plate at a 45-degree angle so the plate “traps” the gas. Once lit, introducing the preheat oxygen can extinguish the flame.

Do you turn on oxygen or acetylene first?

OXY-ACETYLENE We recommend closing the oxygen valve first whenever turning off an oxy-fuel torch system especially when Acetylene is fuel.

Can you use propane for cutting torch?

The gases you can use with oxygen in cutting torches includes acetylene, propane and others. … Acetylene burns much hotter than propane and therefore can cut quicker; but propane is usually cheaper than acetylene and can be used just as effectively in a cutting torch.

What is the correct flame for preheating before cutting?

c) Neutral flame is used for most welding operations and for preheating during cutting operations. When welding steel with neutral flame, the molten metal puddle is quiet and clear; the metal flows easily without boiling, foaming, or sparking.

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?

Article first time published on

Is a plasma cutter better than a torch?

Cutting precision: Plasma typically cuts quickly and with minimal slag, providing smooth cuts with a narrower kerf than what’s produced by oxy-fuel torches. … Faster speeds on thinner metals: Plasma can cut thinner metals faster than oxy-fuel can, and with minimal or no metal distortion.

Can aluminum be welded with oxy-acetylene?

Metal which can be welded with oxy-acetylene flame include iron, steel, cast iron, copper, brass, aluminum, bronze as well as many alloys may be welded. The oxy-acetylene flame is also used for cutting metal, case hardening and annealing.

How do you cut through thick metal?

Cut Metal with Your Circular Saw It may not be an obvious choice, but fitted with the right blade, a circular saw is a great metal-cutting tool. In our test, it cut through rebar like a hot knife through butter. You can cut mild steel up to about 3/8 in. thick using a ferrous-metal-cutting blade.

Can you store oxygen and acetylene together?

Oxygen storage. Oxygen cylinders shall not be stored near highly combustible material, especially oil and grease; or near reserve stocks of carbide and acetylene or other fuel-gas cylinders, or near any other substance likely to cause or accelerate fire; or in an acetylene generator compartment.

How do you start oxycodone?

Separately purge both oxygen and fuel gas lines.
Open fuel gas valve 1/2 turn.
Ignite flame with striker.
Increase fuel gas flow until flame leaves end of tip and no smoke is present.
Decrease until flame goes back to tip.
Open oxygen valve and adjust to neutral flame.
Depress oxygen lever and make necessary adjustments.

Why does my oxy acetylene torch pop?

The reason that an oxyacetylene cutting torch will pop and go out is because of a problem with gas flow. Usually this is either an issue with flow settings, a leak or blockage.

What is the difference between plasma cutting and oxy-fuel cutting?

Plasma cutting is made possible by introducing electricity into compressed air to create an ionized, imbalanced plasma gas. … Oxyfuel cutting is where an oxygen fuel gas flame preheats the material to its ignition temperature, then a powerful oxygen jet is directed at the material.

How thick of steel can you cut with oxy acetylene?

Oxy-fuel torches also offer versatility, as they are capable of cutting, welding, brazing, soldering, heating and gouging. The average hand-held system can cut steel 6 to 12 inches thick. However, some oxyfuel hand torches are able to cut steel more than 20 inches thick.

Can oxy acetylene torch cut stainless steel?

An oxy-acetylene torch is fairly useless against a good grade of stainless steel. You can melt it away, but oxidation is the key to ”burning” regular steel with an acetylene cutting torch, and stainless is stainless because of alloying metals that make it very oxidation resistant.

What is the ratio of oxygen to acetylene?

Table : Fuel Gas CharacteristicsFuel GasMaximum Flame Temperature °COxygen to fuel gas Ratio (vol)Acetylene3,1601.2:1Propane2,8284.3:1MAPP2,9763.3:1

How does one correct for too much preheating when cutting?

Too much preheat will result in a rounded top edge as well as a significant increase in slag. Often times this increase in slag will result in a cut that will not drop from the base plate. Sometimes the slag is so tenacious the part must be beat out of the plate with a sledge hammer.

What type of flame is needed for oxy fuel cutting?

A Neutral Oxy Acetylene Flame is used for Welding, Brazing and Silver Soldering most metals and is therefore the most common type of flame to use. A Neutral Flame is also used for Oxy Acetylene Cutting.

What burns hotter 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.

What is the hottest cutting torch?

The hottest most-versatile gas, acetylene, is very easy to use for all purposes. Pre-heat time for cutting and gouging is relatively short because the flame temperature is between 5,600 and 5,800 F.

Can cast iron cut Oxy?

Generally, oxy-fuel torches are used for heavy metals such as steel and are frequently used in scrap yards to cut scrap metals. These torches should not be used to cut metals like cast iron, aluminum, or stainless steel.

Do you need gas to operate a plasma cutter?

Gas is needed for a plasma cutter in order for it to work and create the plasma. As mentioned, the most popular gases to use are oxygen, nitrogen or argon. … Nitrogen is the best choice when it comes to cutting aluminium and stainless steel and it can provide an excellent cut quality.
