The delivery pressure range determines the range of working pressures you can set with your regulator. For acetylene, the most common maximum delivery pressure is 15 PSIG, as exceeding this can be unsafe. Both the Harris 450-15-300 and Harris 425-15-510 offer a 0-15 PSIG delivery range, ideal for most cutting, welding, and heating tasks. Having options within this range allows users to tailor pressure to their specific application, ensuring both safety and effectiveness.
