Setting the appropriate pressure for a second stage regulator is primarily influenced by the desired system pressure. The second stage regulator is designed to reduce pressure to a specific level suitable for the application it serves. Each application may require a different downstream pressure to ensure optimal performance, safety, and efficiency. Therefore, understanding the system's requirements and the desired operating pressure is crucial in correctly adjusting the second stage regulator.

While ambient temperature and regulator location can have some impact on the performance and efficiency of the regulator, they are not direct contributors to the setting of the pressure itself. Ambient temperature may affect gas density and pressure, but the primary factor in determining the regulator's output setting remains the desired pressure for the system it services. The regulator location can also introduce considerations such as potential pressure drops or fluctuations due to distance from tanks or other equipment, but again, it doesn't dictate the actual setting for the regulator. Ultimately, setting it according to the specific requirements of the system is paramount.
