Abstract (en)
Anti-shock device for high-frequency welding machines configured to intervene in a much quicker way, when the resistance between the molds of the welding press reaches a value lower than a predetermined value, so as to open the supply circuit of the triode grid and lock the latter, to avoid the formation of arcs or discharges between the molds.
