How Hot Does A MAPP Gas Torch Get?

The in-air flame temperature of MAP-Pro fuel is 3,730 degrees Fahrenheit.

Is it propane or MAPP that burns hotter?

Now that we’ve studied propane gas and MAPP gas separately, let’s compare the two fuel types side by side based on a few key factors:


It’s general knowledge that any form of gas, due to its extreme flammability, necessitates extra caution. In this case, one sort of gas poses a greater risk than the other. Extreme MAPP exposure, according to the National Institute for Occupational Safety and Health (NIOSH), is instantly harmful to life and health (IDLH).

Propane gas, on the other hand, is not harmful to human health. Because of its safety, even the United States Department of Agriculture promotes propane gas grills. Propane gas is the clear winner in terms of safety. Regardless, if you’re careful enough, you can utilize MAPP gas without issue.


Now let’s compare the temperatures of MAPP gas and propane; is MAPP gas hotter than propane? Yes is the correct response. MAPP gas has a maximum temperature of 3,730 degrees Fahrenheit, compared to 3,600 degrees Fahrenheit for propane.

What is the temperature of the flame on a map gas 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.

Why isn’t MAPP gas available anymore?

MAPP gas was a trademarked term for a fuel gas based on a stabilized blend of methylacetylene (propyne), propadiene, and propane owned by The Linde Group, a branch of the defunct global chemical giant Union Carbide. The original chemical composition, methylacetylene-propadiene propane, inspired the name. The term “MAPP gas” is also commonly used to refer to UN 1060 stabilized methylacetylene-propadiene (unstabilised methylacetylene-propadiene is known as MAPD).

MAPP gas is often recognized as a safer and more convenient acetylene replacement. True MAPP gas production in North America came to an end in early 2008 when the single surviving facility in the country stopped producing it. However, many current “MAPP” goods are actually MAPP replacements. These variants are virtually entirely made of propylene, with minor propane impurities (

Is MAP gas better for soldering than propane?

Lead-free solder melts at a greater temperature than lead-based solder, which is now prohibited. MAPP gas torches are hotter than propane and are therefore a better choice for contemporary solder. Most 1/2- to 3/4-in. pipes and fittings only require five to ten seconds of heating with a MAPP gas torch before solder can be fed into them. But proceed with caution. MAPP gas makes it easier to overheat a joint. The joint is overheated if the flux turns black and the solder refuses to flow into the fitting.

What is the temperature at which a Bernzomatic burns?

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 it oxygen or MAPP gas that burns hotter?

MAPP gas, which is made composed of methylacetylene and propadiene, is substantially less toxic than acetylene. MAPP gas, unlike acetylene, does not explode if the cylinder is damaged or disturbed. It can also resist higher pressures, making it suitable for underwater activities such as ship repair. Although MAPP gas flames do not burn as hot as acetylene flames, some say that it meets or exceeds acetylene’s welding capabilities.

Because oxygen is required to sustain any flame, it is also required for the operation of all blowtorches. But why do we need a compressed oxygen cylinder if the gas is already present in the air? Because acetylene and MAPP gas would not burn as hot if it didn’t have it. Oxygen functions as an accelerant, causing the fuel to burn faster and at a higher temperature.

Oxygen and acetylene (thus the name “oxyacetylene torch”) are commonly used in welding torches because they produce flames that range from 5000 to 6000 degrees Fahrenheit (2760 degrees Celsius to 3316 degrees Celsius). In fact, the oxyacetylene-propane mixture produces hotter flames than any other gas mixture. When pure oxygen is added to the flame, the temperature of acetylene rises to over 1000 degrees Fahrenheit (538 degrees Celsius), while the temperature of MAPP gas rises to over 1500 degrees Fahrenheit.

Because of the scalding flames, it’s crucial to know what you’re doing before picking up a blowtorch. We’ll explore at the safety precautions involved in beginning one in the next section.

MAPP gas or acetylene, which is hotter?

To many contractors and experts, the Mapp gas solution appears to be far superior at first appearance. The higher temperature of the oxygen-acetylene rig, on the other hand, is a critical element that should not be neglected.

Is it butane or MAPP gas that burns hotter?

The hottest gas is MAPP, which is created by mixing liquid petroleum and methylacetylene-propadine. It burns at roughly 3650 degrees F, or 2010 degrees C.
