FIELD: pipes coupling. SUBSTANCE: aggregate for pipes electrical hydraulic pulse pressing on has in series connected step-up transformer, connected to network, high-voltage rectifier, capacitors battery, discharging contour and processing assembly with electrode. Aggregate is notable for the fact, that to increase reliability and to decrease power consumption it is provided with switch of polarity connected between high-voltage rectifier and capacitors battery, and is provided with switch control joint made in the form of voltage sender connected to capacitors battery terminals, connected to it polarity definition block and drive of polarity switch connected to the block output through power amplifier. EFFECT: increased productivity.
