Flashback Prevention

Backfire preventers are devices that are installed so that they do not reach the gas tank in the event of a backfire when using acetylene gas for welding or thermal cutting. A tool using acetylene gas is obliged to install a backfire prevention device, and acetylene gas cannot be used without this. There are two types of backfire preventers: water-sealed safety devices and dry safety devices, but in recent years many dry safety devices have been sold. It is a mechanism that digests the backfired fire with a fire extinguishing filter and stops the gas outflow by the check valve. Materials such as brass are widely used as the material.
