AI Technical Summary
In existing welding wire monitoring devices, spring-type limit switches are prone to wear and have poor environmental adaptability, resulting in limited service life and easy malfunction, which affects welding efficiency and equipment reliability.
By employing a ring-shaped proximity switch sensor, the welding wire status is detected non-contactly. Combined with the welding wire tube and guide block structure, the welding wire penetration can be monitored in real time, reducing mechanical wear and the risk of failure.
It improves the reliability of welding wire monitoring and the service life of the equipment, reduces maintenance costs, and increases production efficiency and equipment applicability.
