Gas-One portable butane stove with a propane attachment kit (included with every Gas-One stove) that allows the unit to be used with both 8oz butane cartridges and 16.4oz propane and 16.5oz FatBoy fuel canisters. Somebody probably plugged a MAPP (yellow) canister into this one. Propane burns at 3500°F and MAPP brazing gas is at 5700°F...

Mapp gas is 3730 vs 3600 unless you burn oxygen with it.

Not the old (pre-2008) MAPP gas though. These going through a burner with proper jetting and airflow will still churn out a good 4500+, more than enough to chew through a pot. The yellow canisters available now are MAP PRO, and these are nothing but a scam. It is a mixture of butane and propane and is designed to fool users of original oxyMAPP into buying something that is barely more efficient than oxypropane or even a well jetted air-propane torch. Supposedly, the industry reason for stopping MAPP production in the USA was because "oxyacetylene is more economical in bulk for users who have to pay more constantly while buying the much smaller MAPP canisters". That is an absolute crock of shit. Since when did the government care about reducing spending for ordinary people? Even the smallest oxyacetylene rig is not cheap and it usually consists of many components hauled around on a backpack or wheeled caddy. Then I realized that the BATFU had also managed to stop vendors from selling pocket sized thermite charged breach pens, breach torches, and other portable devices that allow anyone to easily cut through a padlock, fence, door, or wall in seconds. Prior to 2008, thermite products HAD been available for commercial sale but now they require 'certificates of safety and instruction' and can only be ordered in bulk by organizations like volunteer fire depts, college dive teams, LE and mil.

The MAPP stoppage made sense after that. The powers that be don't want the proles having an easily totable kit that can cut through metal locks and barriers in seconds and exfil/infil an area at will. A portable, simple OxyMAPP torch will easily eat through padlocks and cut windows out of metal shipping containers and allow a civilian outfit to perform at tactical levels.

Since we have no access to real MAPP gas or solid fuel breach cartridges now, I and several other guys here carry THERMAL LANCES in our work and bugout kits. They are 2 feet long steel brake lines or steel arrow shafts stuffed with steel wool down their cores and fitted onto the end of an oxypropane torch gun and fired by these 1oz portable O2 brazing canisters. Light the steel wool at the business end with a regular lighter and once the flame takes, turn on the O2 flow and adjust until you get a spearhead shaped, blinding white-purplish flame burning absolutely clean with almost no smoke. That is a 7800°F breaching jet capable of cutting through ANY obstacle in an emergency. Careful, that flame is emitting a lot of energy in the UV spectrum so try to minimize your skin and eye exposure to it if you are using in an emergency with no protective gear. When we are using ours at work to cut various metal stuff at worksites, all precautions pertaining to welding applies. A simple thermal lance is enough to let you get people to safety through a previously barricaded area in the event of a fire, flash flood, or active shooter situation. And just based on normal current events, it seems that a breaching tool like a thermal lance should belong in every able person's survival kit and a converted torch kit is small enough to fit into a niche in any work duffel or tactical backpack. A 1oz O2 cylinder will give you enough oxy for 5 minutes of full powered blasts and each arrow shaft "fuel cartridge" will give you decent enough burn time depending on your O2 flow that will be sufficient to cut a window right around the lock mechanism of a commercial walk in freezer like the one an Arby's manager was accidentally trapped in and froze to death last year. Just be aware that the fuel rod is burning downward at a steady pace and when it reaches about 2 inches from the torch head, discard and replace with a new rod so your torch doesn't get damaged.

These work. We used them to cut 90 to 115 lb rail when stripping out old tunnels. A lot of cuts were done under a foot or so of water. Takes a little practice but you pick it up pretty quick. If the bolts stayed under water we could just unbolt them (cheaper). If the water level covered and uncovered the bolts over the years they were rusted solid and we had to cut the fish-plates or the rail.

Thank you,
MrSmith
