2. Oxy-fuel welding and cutting - Wikipedia

   en.wikipedia.org/wiki/Oxy-fuel_welding_and_cutting

   For cutting, the setup is a little different. A cutting torch has a 60- or 90-degree angled head with orifices placed around a central jet. The outer jets are for preheat flames of oxygen and acetylene. The central jet carries only oxygen for cutting.

3. Thermal lance - Wikipedia

   en.wikipedia.org/wiki/Thermal_lance

   A thermal lance, thermic lance, oxygen lance, or burning bar is a tool that heats and melts steel in the presence of pressurized oxygen to create very high temperatures for cutting. It consists of a long steel tube packed with alloy steel rods, which serve as fuel; these are sometimes mixed with aluminum rods to increase the heat output.

4. MAPP gas - Wikipedia

   en.wikipedia.org/wiki/MAPP_gas

   MAPP/oxygen was advantageously used in underwater cutting, which requires high gas pressures (under such pressures acetylene can decompose explosively, making it dangerous to use [3]). However, underwater oxy/fuel gas cutting of any kind has been largely replaced by exothermic cutting [ 4 ] because it cuts more quickly and safely.

6. Underwater cutting and welding - Wikipedia

   en.wikipedia.org/wiki/Underwater_cutting_and_welding

   Oxygen arc cutting and arc welding underwater requires greater skill and stamina than working in a dry and stable environment. The underwater environment imposes several limitations and restrictions on both the equipment and the operator, and the restriction of short bottom times at greater depths for surface-oriented divers makes efficient working important to getting the job done in a ...

7. Flashback arrestor - Wikipedia

   en.wikipedia.org/wiki/Flashback_arrestor

   The flashback arrestors are suitable for most technical gases (fuel gases) such as acetylene, hydrogen, methane, propane, propylene and butane as well as oxygen and compressed air. Flashback arrestors have to be tested for gas non-return, for tightness and for gas flow by a qualified person depending on the country specific regulations.
