What is the pressure limit for a low-pressure fuel gas regulator?

The pressure limit for a low-pressure fuel gas regulator is 40 psi. This specification is important because low-pressure fuel gas systems are commonly used in conjunction with oxyfuel cutting and welding processes. Operating within this pressure range ensures safety and efficient performance while preventing the risk of gas leaks or hazardous situations that may occur with higher pressures.

In the context of oxyfuel cutting, maintaining the correct pressure helps achieve optimal flame characteristics, which are critical for accurate cutting. Using a regulator that exceeds the 40 psi limit could lead to excessive fuel gas flow, making it difficult to maintain a stable flame and negatively impacting the quality of the cut.

Understanding the proper pressure limits of gas regulators ensures that operators can work safely and effectively with the tools and materials involved in oxyfuel applications.
