Oxy-fuel welding torch (commonly called oxyacetylene welding, oxy welding, or gas welding in the United States) and oxy-fuel cutting are processes that use ...

3. Blowtorch - Wikipedia

   en.wikipedia.org/wiki/Blowtorch

   Liquid-fueled torches are pressurized by a piston hand pump, while gas torches are self-pressurized by the fuel evaporation. The term "blowtorch" is commonly misused as a name for any metalworking torch, but properly describes the pressurized liquid fuel torches that predate the common use of pressurized fuel gas cylinders.

4. MAPP gas - Wikipedia

   A set of MAPP and oxygen cylinders is used for oxy-fuel welding and cutting.. MAPP gas was a trademarked name, belonging to The Linde Group, a division of the former global chemical giant Union Carbide, for a fuel gas based on a stabilized mixture of methylacetylene (propyne), propadiene and propane.

5. Flashback arrestor - Wikipedia

   en.wikipedia.org/wiki/Flashback_arrestor

   A flashback arrestor or flash arrestor is a gas safety device most commonly used in oxy-fuel welding and cutting to stop the flame or reverse flow of gas back up into the equipment or supply line. It protects the user and equipment from damage or explosions.

6. Blowpipe (tool) - Wikipedia

   en.wikipedia.org/wiki/Blowpipe_(tool)

   While blowing air is effective, blowing oxygen produces higher temperatures, and it is also practical to invert the roles of the gasses and blow fuel through air. Contemporary blowtorches and oxy-fuel welding and cutting torches can be considered to be modern developments of the blowpipe. Kit for blowpipe analysis Carl Osterland, Freiberg, c. 1870

7. Lead burning - Wikipedia

   en.wikipedia.org/wiki/Lead_burning

   The torch used for lead burning is a small, hot, gas flame. Oxy-acetylene is most commonly used, as it is easily portable. A small size #0 nozzle is usually used, sometimes with a miniature torch body, but the torch is otherwise the same as that used for steel or copper work.
