How do you choose the correct nozzle size for the torch?
Determine the metal thickness you want to cut. Select the tip size rated to cut that thickness or beyond. The tip size is based on the cutting oxygen gas orifice (using drill index sizes) – not always the pre-heat orifices.
How do I choose a gas cut nozzle?
Four Steps to Proper Nozzle Selection
- Choose One-Piece or Two-Piece Nozzle: Acetylene – one-piece nozzle always. …
- Choose Series: ANM, ANM-E, PNM, PNM-E, AFN nozzles. …
- Choose Preheat Capacity: Choice of nozzle depends on preheat capacity. …

What determines the size tip to be used for cutting pipe?
diameter
A pipe’s diameter determines what size cutting tip is needed to cut that pipe. 8.
What size torch hose do I need?
Hose Size: The I.D. (internal diameter) of hose used for most welding and cutting purposes ranges from 3/16-in. to 3/8-in (4.8 to 9.6 mm). When the length of hose required between regulator and torch is not more than 25 ft., 3/16- in. hose is adequate for all welding, and for most cutting and heating.
How do you set a cutting torch?
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.
What is b Size fitting?
Standard Duty: “B” size fittings are by far the most common in our industry and probably comprise 95% or more of the market. They are primarily used for oxy-fuel applications that require standard or medium gas volumes.
What is Type B hose?
RRL Type B Hose has excellent heat and abrasion resistance. It is resistant against grease, oil, acids, ozone, fungus, alkalis, heat & chemicals.
What is the max pressure for acetylene?
15 psig
Maximum pressure. Under no condition shall acetylene be generated, piped (except in approved cylinder manifolds) or utilized at a pressure in excess of 15 psig (103 kPa gauge pressure) or 30 psia (206 kPa absolute).
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.
What type of hose is used for oxygen?
In this case, the oxygen hose is invariably green, and the fuel hose is always red. The types of fuel used vary but the most commonly used are propane and acetylene. Natural gas, methylacetylene-propadiene (MAPP), and propylene are also used.
Which type of hose is used for acetylene fuel gases?
Hoses are manufactured in three common colors: black, green, and red. The use of these colors is not standardized. However, the red hose is usually used for carrying acetylene or other fuel gases. Either the green or the black hose is used to carry the oxygen.
How many types of cutting torches are there?
There are two types of cutting torches : low-pressure cutting torches and high-pressure cutting torches.

How do you cut gas?
How thick can a cutting torch cut?
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.
What metals can a torch cut?
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. And while oxy-fuel torches aren’t dependent on primary power or compressed air, they do require purchase of gas.
What kind of torch can cut steel?
An oxy-acetylene torch, also known as a blow torch, is a dangerous cutting system, but it’s also a powerful and useful tool if you need to cut steel. By creating a safe work environment and carefully monitoring the pressure of the oxygen and acetylene, you can use an oxy-acetylene torch for any number of projects!
What can plasma cut?
Plasma cutting is a process in which electrically conductive materials are cut through by means of an accelerated jet of hot plasma. Typical materials that can be cut with a plasma torch are steel, stainless steel, aluminium, brass, copper and other conductive metals.
How is thick steel cut?
Start with Thickness:
- Thinner than 0.080” use laser.
- Thinner than 0.125 use plasma or laser.
- Thinner than 0.250 use waterjet, plasma, or laser.
- Over 8” use oxy-fuel.
- Over 2” use oxy-fuel or waterjet.
- Over 1.25” use plasma, oxy-fuel, or waterjet.
What is the kindling temperature of iron?
Autoignition point of selected substances
| Substance | Autoignition | Note |
|---|---|---|
| Iron | 1,315 °C (2,399 °F) | 1315±20 |
| Lead | 850 °C (1,560 °F) | 850±5 |

What is the name of the torch part made of copper?
Shield. Just like its name, a shield protects all of the other consumables from sparks and molten metal. Most shields are made of copper and also provide the proper stand off distance between the nozzle and the work piece.
Which gas is used in plasma cutting?
Compressed Air is the most commonly used gas for lower current plasma cutting and works well for most metals from gauge thickness to 1 inch. It leaves an oxidized cut surface. Compressed air can also be used for plasma gouging on carbon steel.
