Flashback arrestors are safety devices used in welding and cutting applications to prevent the dangerous backflow of gases, specifically oxygen and acetylene, into the equipment. These arrestors are typically installed in the gas lines between the regulator and the torch. Their primary function is to prevent flashbacks—when a flame travels back into the gas lines, potentially causing an explosion. Flashback arrestors are crucial for protecting welding systems and operators from the risks associated with flashbacks or backfires.
The Oxygen & Acetylene Set includes arrestors designed for both oxygen and acetylene gas supplies. The arrestors for oxygen and acetylene are often integrated into a single unit or sold as separate components, ensuring safe operation of both gases during welding and cutting. The devices usually contain a check valve and a flame arrestor, which work together to stop any harmful backflow of gases.
These arrestors are essential in preventing damage to hoses, regulators, and other equipment while ensuring the safety of the operator. Their use is mandatory in many industries, such as construction, automotive repair, and metalworking.
