AR-55 Industrial Acetylene Regulator

The AR-55 Wear-Resistant Industrial Acetylene Regulator is specifically designed for industrial welding, cutting, and metalworking operations, providing stable and reliable acetylene gas output even under complex working conditions. Its wear-resistant design ensures that the internal core components remain smoothly operational during long-term, high-frequency use, reducing the risk of instability caused by component wear and enhancing overall work efficiency and safety. The AR-55 can handle an input pressure of 0–2.5 kg/cm² and precisely regulates the output pressure to 0–40 kg/cm², meeting the diverse pressure requirements of various welding processes, cutting operations, and laboratory-level precision tasks.
The regulator features a round G5/8" threaded inlet, ensuring a secure connection with most acetylene cylinders on the market and minimizing leakage risks. The outlet is equipped with a 3/8" hose barb compatible with 5/16" inner diameter hoses, making installation and removal of gas lines convenient and allowing quick adaptation to different worksite environments and mobile operations. Its compact and robust design not only facilitates portability but also provides stable gas flow support in industrial workshops, welding sites, outdoor construction, and a variety of other application scenarios.
