FIELD: process engineering.
SUBSTANCE: invention relates to high-frequency welding of polymer materials used in medicine. Proposed device comprises power supply connected with switching unit with electromagnet with moving core coupled with moving welding electrode, and, via HF generator, with moving welding electrode, fixed welding electrode, starting assembly, microprocessor control unit, current transducer and amplitude detector. Said switching unit is made up of two electronic switches. Current transducer is connected in between HF generator output and moving welding electrode, while amplitude detector is connected in between current transducer and microprocessor control unit. The latter is connected with starting assembly, first electronic switch control input connecting power supply with electromagnet, and with second electronic switch control input connecting power supply with HF generator.
EFFECT: reliable sealing, power savings.
