What component is turned clockwise to allow gases to flow to the hoses and torch?

The component that is turned clockwise to allow gases to flow to the hoses and torch is the regulator knob. The regulator is responsible for controlling the pressure of the gases being delivered from the gas cylinder to the torch. Turning the knob clockwise typically increases the pressure setting, allowing gas to flow more freely to operate properly.

Understanding the role of the regulator is crucial in soldering and brazing because it ensures that the correct amount of fuel gas and oxygen is mixed for the desired flame characteristics.

While the other components, such as the pressure adjusting screw, flow control valve, and safety relief valve, play significant roles in managing pressure and ensuring safety, it is the regulator knob that directly regulates and controls the flow of gases to the torch by adjusting the pressure settings. This is essential for obtaining an optimal flame for soldering or brazing tasks.
