What part of the torch is regulated to maintain steady gas flow?

The regulator is the component of the oxyfuel torch that is specifically designed to maintain a steady flow of gas, ensuring safe and efficient operation. It reduces the high pressure from the gas cylinder to a lower, more manageable pressure suitable for cutting or welding. This regulation is crucial because if the gas pressure fluctuates, it can lead to inconsistent flame characteristics, which can compromise the quality of the cutting process and pose safety risks.

Understanding the function of the other parts helps clarify the role of the regulator. The cutting tip and nozzle are primarily involved in focusing and shaping the flame during the cutting process but do not manage or control the gas flow itself. The gauge serves to display the pressure level in the cylinder or system, but it does not actively regulate the flow of gas; it simply provides information to the operator. Thus, the regulator is integral to achieving a stable and controlled gas flow, which is essential for effective oxyfuel cutting.
