PodTa známého stavu techniky sa rámsvorkovnice k výlisku hlbdkého zvona pri-vára na zváracom lise s manuálnou obslu-hou. Obsluha zoberie z pásového doprav,ni-ka hlboký zvon s privarenou prechodkou,vloží ho na spodnú elektrodu, ktorá mátvar uzavretého prstenca s vnútornou duti-nou. Spádná elektroda sa dotýká zvona zvnútornej strany a do jej dutiny zapadnespodná část prechodky. Rám svorkovnicena hornú stranu zvona Obsluha položí tak,že otvorom v ráme svorkovnice prestrčíhornú část prechodky, privarenej na zvone.Potom uvedením lisu do chodu horná elek-troda dotlačí rám svorkovnice na zvon aprivarí ho v miestach vytvořených výstup-kov na rám svorkovnice. Táto práca vyža-duje trvalú přítomnost íudskej obsluhy avzhladom k tomu, že sa manipuluje s hor-nými výliskami prichádzajúcimi .navzájomdo styku je prevádzka velmi hlučná.According to the state of the art, the terminal box is molded to a deep-bead molding on a welding press with manual operation. The operator takes from the belt conveyor, a low-bladed bell with a welded-in fitting, to the lower electrode, which is a closed ring-shaped cavity with an inner cavity. The downward electrode touches the bell of the inner side and into its cavity the underside of the bushing. Frame of the terminal box of the upper side of the bell The operator puts the upper part of the bushing welded to the bell through the opening in the frame of the terminal box. Then the upper electric press pushes the terminal box frame to the bell and welds it in places created by the outlet-metal to the terminal box frame. This work requires the permanent presence of human operators and the operation is very noisy due to the handling of the upper moldings coming into contact with each other.
