What is the maximum operating pressure setting for an acetylene torch?

The maximum operating pressure setting for an acetylene torch is critical for safe and effective use. Acetylene is a highly flammable gas and must be handled carefully to prevent hazardous conditions.

The correct pressure setting is 15 psig, as acetylene should not be used at pressures exceeding this limit. Operating above this range can lead to instability in the gas mixture, potentially causing flashbacks or even explosions due to the properties of acetylene being sensitive to pressure changes.

Furthermore, it is important to use acetylene in conjunction with an appropriate regulator designed for lightweight gases, ensuring that the pressure does not exceed 15 psig for safe operation. This reflects industry standards and safety practices aimed at minimizing risks during welding or cutting applications.
