What is the primary function of the cutting orifice in the torch?

• A. To control the temperature
• B. To enable preheating
• C. To allow oxygen to flow during cutting
• D. To regulate gas pressure

Answer: (C)

The primary function of the cutting orifice in the torch is to allow oxygen to flow during the cutting process. In oxyfuel cutting, the torch uses a mixture of fuel gas and oxygen to create a high-temperature flame. However, the critical role of the cutting orifice is to introduce a concentrated stream of oxygen into the cutting zone. This oxygen enhances the combustion of the material being cut, allowing it to reach the ignition temperature and subsequently oxidizes it, effectively creating a cut. Without the proper flow of oxygen through the cutting orifice, the efficiency and quality of the cutting process would significantly decrease. It ensures that there is a sufficient amount of oxygen available exactly where it is needed for effective cutting. Although preheating, controlling temperature, and regulating gas pressure are important elements of the torch function, the defining feature of the cutting orifice specifically pertains to its role in facilitating the flow of oxygen during the cutting operation.
