A. Avoiding Welding Sparks During oxygen acetylene welding, it is easy to generate a large amount of sparks during the welding process. Therefore, during welding work, it is necessary to install a bottom flashback preventer to avoid danger. B. Ensure Welding Quality Installed below the welding area, flashback arrestors can ensure the quality of the welding bottom seam and improve the welding quality. C. Easy to Use First, check whether the bottom flashback arrestor works normally, and then adjust the flow and temperature of oxygen and acetylene to make them reach the combustible state. It is necessary to monitor the bearable temperature and pressure in real time. D. Craftsmanship The built-in check valve can prevent gas backflow. The brass structure is sturdy, durable, and corrosion-resistant. Easy to control, inspect, clean, and maintain. E. Need to Attention The bottom flashback preventer must be checked for normal operation to ensure welding quality and safety. It is necessary to regularly clean and maintain to ensure its normal operation. F. Type: HF - 2 G. Size: M16*1.5 H. Working medium: Acetylene / Oxygen I. Working pressure: Medium pressure (MPa) J.
