Is MAPP gas safer than acetylene?
Compared to acetylene, MAPP gas, which is made up of methylacetylene and propadiene, is much less dangerous. Unlike acetylene, MAPP gas is not prone to explosion if the cylinder is hit or bumped. It also can withstand higher pressures, which means it's good for underwater work, like repairing ships.
What is hotter MAPP gas or acetylene?
Similarly, what burns hotter than MAPP gas? Acetylene is probably the hottest burning fuel gas available to us. It's also been around longer than propylene and MAPP gas. Historically it's the gas associated with flame hardening because of its hotter temperature. However, its challenge comes with achieving a high enough withdrawal rate.

What replaced MAPP gas?
BLUEFIRE Modern MAPP is a modern substitute to the traditionally known MAPP fuel gas, which was discontinued since 2008.
Can you cut metal with MAPP gas?
MAPP gas is commonly used instead of acetylene because it can be used above 15 psi and is therefore far less dangerous while cutting steel up to 12 inches thick. MAPP burns at a lower temperature than acetylene and is a liquefied petroleum gas that can be stored more easily since it compresses easily.
What do you use MAPP gas for?
A MAPP (methylacetylene-propadiene propane) torch is a type of portable flame device that is used to heat various objects. A MAPP torch can get much hotter than a propane torch and therefore is very useful for various applications. MAPP torches are most often used for welding, soldering and brazing pipes.
Why is MAPP gas no longer available?

Can you cut metal with a Bernzomatic torch?
The Bernzomatic Cutting, Welding, and Brazing Torch Kit really is a cool tool. I pushed it hard on my first foray, not only cutting, but cutting a really thick piece of metal.
What gas do you use for a cutting torch?
Acetylene is still one of the most commonly used fuel gases for a cutting torch as well as for heating. Soldering, brazing and welding are also done with acetylene. Acetylene contains the greatest amount of hydrocarbons. Acetylene produces the highest temperature of the commonly used fuel gases.
What are the three valves on a cutting torch?
On an oxyacetylene torch system there are three types of valves: the tank valve, the regulator valve, and the torch valve. Each gas in the system will have each of these three valves. The regulator converts the high pressure gas inside of the tanks to a low pressure stream suitable for welding.
What gas does Bernzomatic use?
cylinder is designed to quickly refuel your Bernzomatic micro torches, lighters, cordless soldering irons and other butane-powered devices. It features a universal fueling tip for easy refilling and odorized butane for enhanced safety. Butane Fuel has an in-air flame temperature of 3,150°F.

It's not anything to do with copper and MAPP. It's chemistry. There is a lot more hydrogen available in the MAPP flame then in the acetylene flame, so welds done with MAPP (or any other LP derivative) suffer from hydrogen embrittlement.
Ernie Leimkuhler
Besides Grant's quote from my seminar you will soon find MAPP non-existent. This has to do with one of it's constituent gasses. MAPP is Methyl-Acetylene Poly-Propylene. One of the gasses used to make MAPP is Propadiene. Propadiene is now worth more to the plastics industry than it is to the welding industry, so MAPP is being phased out. In Seattle it is almost impossible to get in anything bigger than a disposable propane torch sized can..

And yes indeed, you can use acetylene regulators for any propane gas or derivative (MAPP, Chemtane, etc., see Ernie's post for a list). At least they'll bolt up fine. I use mine for any fuel gas if I need to.

I last gas welded in my shop around 10 years ago. It has absolutely no commercial value to me as a fabricator.
What is Mapp gas?
Mapp, or MAPP gas, is an acronym for methyl-acetylene propadiene propane, and it’s highly effective. Butane is another element of Mapp gas, and that contributes to the high-quality flames it’s known for. While Mapp gas was highly effective and widely used for years, it was discontinued in 2008.
What is a good substitute for Mapp gas?
The best modern alternative to Mapp gas is known as MAP-pro, which solely features propane and propylene. Many plumbers, welders, and builder-owners find that MAP-pro is a great alternative to propane on its own. Similarly, MAP-pro is widely regarded as a great replacement for Mapp gas itself. They may not make Mapp gas anymore, but ...
What is propane used for?
4. Appliances. Perhaps the most practical use of propane is for running appliances, which it’s ideal for. Sometimes, an electronic ignition water heater won’t heat, but that’s not a problem with propane. Whether it be a hot tub, heated pool, water heater, or fireplace, propane can be used to great effect.
What is the difference between MAP Pro and Propane?
Generally speaking, propane is best used for grilling, powering appliances, generators, and space heaters. MAP-pro, on the other hand, is ideal for soldering. Because of that, propane is best used by consumers, and MAP-pro is ideal for professionals.

Is MAPP gas safe?
Moreover, MAPP gas has the advantage of not needing to be diluted or not needing a special container filler during its transport. Thus, this allows us to transport a great volume of this gas at the same given weight. Besides, this gas is safe for use. In both its gaseous and liquid forms, MAPP gas is colourless.
Can we use MAPP gas in welding?
We can use MAPP gas in combination with oxygen gas for heating purposes, soldering, brazing, and welding. This is due to the high flame temperature of this gas in the presence of oxygen gas (compared to the acetylene gas we use inn welding processes).
Is acetylene gas toxic?
This gas has a fishy odour (at high concentrations) that resembles the odour of acetylene gas. Moreover, this gas is toxic if inhaled at high concentrations. Earlier, this gas was considered as a safe and easy-to-use substitute for acetylene. However, the production of this gas was discontinued because of the cost of production.

Can brazing be done with propane?
Brazing with Propane. Here is the answer to whether you can braze with a propane / air torch. You can but you have to control the environment so that the heat loss to the atmosphere and parts is lower than the heat being put into the braze joint. It is a standard braze alloy that melts over a range of 1250 – 1305 F.
Does MAPP gas require a special torch?
Re: propane and mapp gas Don't use a torch that's made for propane on mapp gas.
Can you sear food with MAPP gas?
Yep. MAPP is actually preferable in fancy restaurants for charring or caramelizing foods over propane or butane, because it won't have any funky odors. With a flame temp as high as 5000°F whatever combustion products are produced from MAPP will be very simple basic compounds and safe, CO2, H2O etc.
Is Mapp gas hotter than acetylene?
Propylene and MAPP gas burn hotter than natural gas and propane. That makes them a better choice for flame hardening applications. You don't want to run out of gas during a flame hardening cycle. Acetylene is probably the hottest burning fuel gas available to us.
Is Mapp gas the same as acetylene?
Compared to acetylene, MAPP gas, which is made up of methylacetylene and propadiene, is much less dangerous. Unlike acetylene, MAPP gas is not prone to explosion if the cylinder is hit or bumped. It also can withstand higher pressures, which means it's good for underwater work, like repairing ships.
How long does a MAPP gas cylinder last?
For me, it lasted about 3-4 hours. If you have a long beadmaking session, toward the end, the bottle will get cold and condensation will freeze on in, and then the flame dwindles.
Can I silver solder with MAPP gas?
Hard soldering (silver soldering) requires temperatures of about 1200 to 1400 degrees F. MAPP should give you this kind of heat, and burns about 350 degrees hotter than propane. MAPP may be overkill for your application however. It is ideally suited for large diameter repairs and makes quick work of big solder jobs.
