Air-acetylene produces a flame temperature of around 4000° F (2200° C). This is hot enough to solder aluminum work glass, repair radiators and braze plumbing fixtures. It is not hot enough to weld steel. When acetylene is burned in pure oxygen, the flame temperature may be as high as 5730° F (3166° C).
Is acetylene hotter than 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.
Is acetylene hotter than Mapp?
Although acetylene has a higher flame temperature (3160 °C, 5720 °F), MAPP has the advantage that it requires neither dilution nor special container fillers during transport, allowing a greater volume of fuel gas to be transported at the same given weight, and it is much safer in use.
What is the advantage of an oxy acetylene torch compared to an air acetylene torch?
What is an advantage of the oxyacetylene flame compared air acetylene? It heats up faster than acetylene flame.
Does acetylene burn hotter than oxygen?
One of the main arguments for acetylene is that it burns hotter. … The maximum neutral flame for acetylene in oxygen is about 5720 F, while the temperature for propane is 5112. This does not, however, mean that propane gives off less heat. Acetylene may burn hotter and can even pre-heat metal faster.
Can I use a propane tip with acetylene?
Propane tips are recessed while acetylene tips are not. You can do it, but it will not be effective, and might actually be quite dangerous. Acetylene needs oxygen at a proper ratio to be fully effective as a cutting torch. Otherwise, you are just getting the metal really hot, rather than burning through it.
Is Oxy Propane better than oxy acetylene?
Propane generates less than 10% thermal energy, whereas acetylene generates 40% of thermal energy in the inner flame cone. This helps ensure better weld quality and cutting using oxy acetylene. … So, there is far more oxygen being consumed when using propane than acetylene.
How hot does acetylene get without oxygen?
Fuel Gas PropertiesBoiling range °F (°C) 1 atm-44 BPFlame temperature in O2 °F (°C)4579 (2526)Latent heat of vaporization at 25° C, Btu/lb, (kJ/kg)184 (428)Total heating value (after vaporization) Btu/lb (kJ/kg)21,800 (51,000)
Why are copper fitting cleaned before soldering or brazing?
It cleans the metal making the solder stick to the fittings and pipe better it cleas oxides and oils. … The longer that copper is kept at the higher brazing temperature, the greater the formation of copper oxide, and nearby valves may be overheated.
Can you light an acetylene torch with a lighter?
For my jeweler’s acetylene torch, I use a desktop striker that makes a spark when you touch it with the torch tip. You can use a match or cigarette lighter to light a torch, but I find these strikers much safer. You can keep your fingers and hand further away from the gas when it ignites.

Is propylene hotter than acetylene?
Propylene is a safer fuel because it is considerably more stable than acetylene. It has a greatly reduced chance of combustion. Propylene also burns hotter which means the cutting tip can be held further away from the work site while still maintaining accuracy.
What is the hottest gas for brazing?

How hot is oxy acetylene flame?
The oxyacetylene process produces a high temperature flame, over 3000 degrees C, by the combustion of pure oxygen and acetylene.
Can LPG replace acetylene?
Propane is the easiest fuel gas alternative to Acetylene to obtain and is normally supplied in cylinders on a Deposit basis, rather than rented (as is usually the case with Acetylene). For most users, Propane works out cheaper, especially for infrequent users of Oxygen + Fuel kits.
Can you weld lead with propane?
Oxy Propane/Propylene Lead Welding Kit Top Quality, Lead Welding Kit for Lead Burning using Oxygen and either Propane or Propylene. Ideal for Roofing Companies and Roofing Contractors wishing to carry out Lead Welding work but find the use of Oxy Acetylene problematic on Insurance or Site Safety grounds.
Is acetylene heavier than air?
Acetylene is the only fuel gas recommended for underground working conditions because it is lighter than air. It is also the only fuel gas, for instance, which can be used to weld steel.
Can you mix MAPP gas and propane?
Yes, MAPP gas works well on a propane torch nozzle, but the flame will be hotter than a propane flame. MAPP is better for soldering copper pipe, but too hot for many smaller copper items. It is also better for brazing and silver solder.
What gas burns hotter than propane?
MAPP gas is much hotter than propane, and when you are cooking, it can quickly burn your metal pot and pans and burn your hands.
Will a propane torch cut metal?
HGX linked up with propane uses significantly less oxygen than acetylene, making it a highly efficient and cost-effective option for cutting metal that doesn’t burn much less hotter than acetylene.
Can you use acetylene without oxygen?
No. Air is enough. Caveat: air is enough to make acetylene burn yellow and make a lot of smoke. To make acetylene’s combustion efficient for max heat, you need to provide a LOT more oxygen right there at the center of the burn than air can possibly provide on its own.
Is silver solder stronger than regular solder?
Silver solder is silver-based filler metal that has been used for years by welders. It’s a silver alloy with some other metals added in, which makes it stronger and able to take more punishment than typical aluminum or copper soldering wire.
Is silver solder stronger than brazing?
Brazing rods look like straightened metal coat hangers, and like solder they become stronger as the percentage of silver they contain increases. The braze is what is melted by the torch to join two metals. For joining copper lines we usually use brazing rods that are made out of a copper-phosphorous combination.
Can you overheat copper while soldering?
Overheating is a major problem when brazing or soldering copper pipe because the flux will burn (become oxidized), stop working, and become a barrier to tinning. In addition, a heavy oxide can be formed on the pipe itself, preventing a bond from forming between the filler metal and the pipe surface.
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.
How hot is the tip of a torch?
Consumer air butane torches are often claimed to develop flame temperatures up to approximately 1,430 °C (2,610 °F). This temperature is high enough to melt many common metals, such as aluminum and copper, and hot enough to vaporize many organic compounds as well.
What is the hottest welding torch?
The Bernzomatic TS8000BT High Intensity Torch Head is the hottest buring torch in the Bernzomatic line. The Instant On/Off trigger ignition provides easier lighting and increased fuel savings. The Large, Optimized swirl flame burns hotter for maximum heat output that provides a 30% faster soldering time.
Why use a striker instead of a lighter?
The striker helps contain the gas until the spark can light it. For my jeweler’s acetylene torch, I use a desktop striker that makes a spark when you touch it with the torch tip. You can use a match or cigarette lighter to light a torch, but I find these strikers much safer.
Why is my torch not clicking?
If this does not work, the burner may be clogged; clean it with a blast of compressed air. If neither of these methods works, you may be low on butane or may have an air bubble in the lighter’s tank. The only way to definitively solve either problem is by emptying the lighter and refilling it with fresh butane.
What type of flame should you use when cutting?
The neutral flame is the flame most generally used when welding or cutting. The welder uses the neutral flame as the starting point for all other flame adjustments because it is so easily defined.
What gas can replace acetylene when welding aluminum?
MAPP for Welding MAPP gas is one of the leading substitutes for acetylene in Oxy-welding.
