Oxygen-acetylene units are inexpensive and versatile.
Often called "gas welders," they use fuel gases and oxygen to weld, cut and bend metal. Developed in 1903 by two French engineers, it is one of the oldest types of welding.
Oxygen-acetylene welds by heating two pieces of metal to a temperature that creates a shared pool of molten metal. Filler is added as needed.
To cut metal, a special torch is used to first heat the material to red hot, then a blast of oxygen is used to cut through the metal.
