When adjusting pressure on a regulator ____________________.

When adjusting pressure on a regulator, turning the regulator clockwise increases the pressure for both oxygen and acetylene gases. This is a standard practice in gas regulation and is crucial for ensuring the safe and effective use of these gases in various applications, such as welding or cutting.

In the context of gas regulators, the design typically allows for clockwise rotation to compress the internal spring mechanism more tightly, thereby allowing more gas to flow through and increasing the output pressure. Understanding the direction of adjustments for each type of gas is essential for safe handling and operation, as improper adjustment can lead to unsafe conditions or equipment malfunction.

Using this method ensures that technicians can set precise and safe pressure levels for their work, adhering to industry standards and safety protocols.
