FIELD: aggregates for pipes electric hydraulic pulse pressing on. SUBSTANCE: processing assembly of aggregate for pipes electric hydraulic pulse pressing on has video control device and connected to control system TV camera to supervise after positioning of electrode of aggregate. Processing assembly differs by the fact, that to increase its service life due to protection of TV camera lens at the moment of aggregate discharge it is provided with holding TV camera cantilever mounted on stationary base, shaft fixed to cantilever through intermediate carrier and also is provided with capable to turn mounted on shaft spring-loaded to cantilever shutter overlapping TV camera lens and with engaged with shutter electric magnet built-in system of control. EFFECT: increased processing assembly service life due to protection of TV camera lens at moment of aggregate discharge.
