Conversely, what is the result of turning the regulator adjusting screw out to the left?

Turning the regulator adjusting screw out to the left is intended to reduce the pressure in the system. When you adjust the screw in this manner, it creates more space within the regulator, allowing less gas to flow through the system. Consequently, the pressure decreases as a result of this adjustment. This understanding is crucial for ensuring proper gas flow and maintaining the safety and efficiency of brazing operations. Proper control of gas pressure is vital to avoid overheating or unsafe conditions during the brazing process, making this knowledge fundamental for effective brazing techniques.
