摘要

Device for preventing, in high frequency electronic welding for plastic materials, the deterioration of welding electrodes and objects to be welded, by an accidental passage of an arc through the material to be welded, characterized by the fact that which provides a relay mounted so that its supply circuit is closed or short-circuited by the arc passing between the electrodes and whose closing or opening actuates the high frequency interlock.
