The highest temperature of an air-fed torch is roughly 2,000 C (3,600 F). A typical primary flame, on the other hand, will only reach temperatures of 1,100 C (2,000 F) to 1,250 C (2,250 F). Oxygen-fueled torches may reach temperatures of up to 2,550 degrees Celsius (4,600 degrees Fahrenheit).
How hot can you get metal with a propane torch?
MAPP gas, which is a combination of propane and methylacetylene-propadiene, burns somewhat hotter than pure propane. The gas in these yellow cylinders burns at a temperature of 3,720 degrees Fahrenheit (2,050 degrees Celsius). Torches built for high-temperature work combine MAP gas with pure oxygen, allowing for complete combustion that would otherwise be impossible in ambient air. The highest temperature of these torches is 5,200 degrees F (2,870 degrees C), which is hot enough to melt iron or steel.
What is the temperature of a Bernzomatic propane torch?
The thin, lightweight cylinder is made of sturdy steel and is easy to grip and handle while working. This item can be used in conjunction with our Digital Fuel Gauge to simply determine how much fuel is left in the cylinder. The flame temperature of propane is 3,600 degrees Fahrenheit in the air.
Is propane or MAPP gas hotter to burn?
MAP-Pro gas burns at 3,730 degrees Fahrenheit, while propane burns at 3,600 degrees Fahrenheit. MAP-Pro gas is a superior alternative to propane for soldering since it heats copper faster and at a higher temperature.
What is the temperature of a Bernzomatic butane torch?

It burns for an hour and a half. A soldering tip for electrical soldering is included. The flame temperature is 3,100 degrees Fahrenheit. Features:
Is it possible to use Bernzomatic on a grill?
Bernzomatic’s TX916 Propane Camping Gas Cylinder holds 16 ounces of clean-burning propane. This portable propane tank with a CGA 600 connection fits all standard portable propane appliances, tabletop grills, and propane torches and is great for on-the-go cooking, grilling, heating, and lighting.
Is it possible to melt gold with a propane torch?
The heat from a propane flame is enough to melt pure gold. It will melt gold alloys as well, but it will not separate gold from other elements such as silver or copper during the melting process. Gold is one of the most valuable elements on the planet, and its use in jewelry is well known. Old gold jewelry can be recycled by melting it down and repurposing it for various purposes. Melting gold can be done in a variety of ways, all of which should be done by a professional.
Is it possible to weld with a Bernzomatic torch?
When inverted, it includes a sturdy brass burn wand, independent fuel and oxygen controls, and is pressure regulated for constant performance, making it perfect for small brazing, welding, and metal-cutting operations.
Is propane or acetylene hotter to burn?
Propane, often known as LPG (liquefied petroleum gas) or LP gas, is a popular fuel. It is carried and kept as a very cold liquid, and if it comes into contact with the skin, it can induce a “frozen burn” or frostbite. Inside a tank or cylinder, liquid propane is converted to gas. Propane is colorless and odorless in its natural state. Manufacturers add a chemical ingredient to propane to give it a unique smell, making it simpler to detect in the event of a leak or spill.
To begin with, propane cannot be utilized in gas welding. When acetylene is burned in the presence of oxygen, a reducing zone forms, which cleans the steel surface. Propane, unlike acetylene, lacks a decreasing zone and so cannot be utilized for gas welding.
Propane can be used for brazing in the same way as acetylene can. Equal result for capillary brazing (silver brazing). Acetylene will be advantageous for Braze “welding” (thick flowing brazing alloys).
Propane, like acetylene, can be used to cut. When cutting with acetylene, the tip of the inner flame cone is usually placed on the metal (1mm from the plate surface). If you try the same thing with propane, you’ll have to wait a long time. The preheat procedure starts faster if you lift the torch to use the outer flame cone. Because propane only produces a modest amount of heat in the inner flame cone (less than 10%), the majority of the heat in the flame is concentrated in the outer cone. In the inner flame cone, acetylene discharges over 40% of its heat.
As a result, acetylene is preferable to propane for cutting. While acetylene is hotter than propane in terms of temperature, the fact is that individuals are cutting with propane wrongly. They make the error of cutting with propane in the same way as they would with acetylene. The heat in the propane warmup flame is not the same as the heat in the acetylene preheat flame. In summary, cutting with propane necessitates a different method, while acetylene preheats faster in general. Because cutting quality is unimportant in shipbreaking/ship demolition yards and scrapyards, propane is frequently used for cutting.
…is a completely other story. It is incorrect to claim that propane produces less heat (plain wrong actually). Although acetylene is hotter, it produces less heat. Oxygen / Propane is used for the majority of the preheating. This is a proven fact. The amount of heat provided from propane is greater.
Propane’s stoichiometric oxygen needs are higher than those of acetylene. The volume of oxygen to fuel gas ratio for the maximum flame temperature in oxygen is 1,2 to 1 for acetylene and 4.3 to 1 for propane. As a result, when Propane is used, significantly more oxygen is consumed. Despite the fact that propane is less expensive than acetylene, the higher oxygen consumption offsets this.
The most significant disadvantage of utilizing propane on board is, without a doubt, the issue of safety.
With a specific gravity of 0,9, acetylene is lighter than air (1). If gas escapes, the temperature will rise. Propane has a Specific Gravity of 1.66, making it heavier than air (as do other hydrocarbon gases such as butane and MAPP* (modified propane gas). Any propane leak in an enclosed space will sink to the deck level, where it will accumulate and may go undetected.
The oxygen-to-gas combination must be within a specified range for propane to burn successfully. There should be four parts propane to 96 parts oxygen in optimal conditions. When the gas burns outside of these parameters, incomplete combustion occurs, resulting in an excess of carbon monoxide. If the space does not have adequate ventilation, this can be quite harmful. Working in enclosed places such as ballast tanks and double bottoms onboard a ship is common. As the deadly gas replaces oxygen in the bloodstream, carbon monoxide overdose can be fatal.

When it comes to propane, what is the flash point?
Another factor to consider when it comes to propane’s flammability is the propane-to-atmospheric-air ratio. Propane must have a propane/air combination of between 2.15 and 9.6 percent to be flammable.
Lower or greater percentages will prohibit combustion, and inappropriate air/gas combination ratios might result in the creation of harmful carbon monoxide gas, which is produced when combustion is incomplete. Propane is one of the safest and cleanest burning fuels available when the propane and air mixture is kept at appropriate ratios.
Additionally, propane, like other fuels, has flammability features that can provide customers with the information they need to understand propane and its applications.
- Propane has a flash point of -156 degrees Fahrenheit. At this temperature, propane that has already been ignited will continue to burn on its own. Unless there is a constant source of fire, propane will extinguish itself if the temperature drops to -157 degrees.
- Atmospheric Ignition Temperature – The temperature at which propane can ignite without an ignition source is between 920 and 1020 degrees Fahrenheit. In comparison, the ignition temperature of gasoline is between 80 and 300 degrees.
- Maximum Flame Temperature – At 3,595 degrees Fahrenheit, propane reaches its maximum flame temperature.
- Propane Octane Number – Propane has an octane rating of 104 to 112, making it an efficient fuel for internal combustion engines built to run on propane. The breakdown of hydrocarbon chains in a fuel determines the octane rating. In general, a higher octane rating denotes better performance and efficiency.
