The maximum inlet pressure indicates the highest pressure the welding flow meter can safely handle from the gas cylinder. It's important to choose a regulator rated for your supply pressure to avoid malfunctions or hazardous leaks. Inlet pressures in this category range from 3000 to 4000 PSIG, covering most industrial gas cylinders. For example, the Harris 3100200 supports up to 3000 PSIG, while the Harris 4400235 is also rated for high-pressure use. With a range of inlet pressure ratings, you can match the regulator to your cylinder for safe, reliable operation.
