Gas welding uses tanks of compressed oxygen and fuel—most commonly acetylene—feeding these gases through hoses to a handheld torch, producing an extremely hot and easy-to-control flame.

Oxy-acetylene welding and cutting processes are as old as the automobile. Gas welding is effective and thorough. Its continuous heat source can control and move puddles of molten metal.

But knowing how to harness that raw power means you’ve got to learn the basics of oxy-acetylene ... at the internals of an acetylene tank — turns out the gas is stored dissolved in acetone ...

Because an air-swirl torch automatically meters the correct gas flow, a technician with such a torch can light the flame and start bringing a joint to temperature before a technician with an ...

Oxyfuel cutting technology followed the development of oxy-acetylene welding by Charles Picard and ... Figure 4 shows a comparative overview of acetylene and propane gas jets with their respective ...

Another nightmare pertaining to portable oxy-fuel units is the unintentional release of fuel gas. Acetylene, the most common fuel gas, has one of the widest mixture ranges between its lower and ...

A century ago, in March 1915, there was a ferocious explosion of an oxy-acetylene gas tank at Felker Brothers Manufacturing Co., as the Marshfield business was then known. The Marshfield Times ...

Dirigo Technologies, an offshoot of Maine Oxy, is the only place in the Northeast that produces acetylene gas, used for welding and metal cutting. The gas is made in Auburn and shipped to Maine ...
