FIELD: mechanics; electricity.

SUBSTANCE: device contains two electrode heads, each of which is executed in the form of the roller electrode established on an axis, placed in the case, a drive of compression of the pneumocylinder with a rod and the mechanism of turn and fixing of a roller electrode. The mechanism of turn and fixing of a roller electrode is executed in the form of the cylindrical sleeve with slots, springs and sleeves with an internal cone and protuberances on the external surface, going into slots of the cylindrical sleeve rigidly fixed on the pneumocylinder. The axis of a roller electrode is rigidly fixed on a rod of the pneumocylinder of a drive of compression on which there is the conic part interacting with an internal cone of the sleeve, resting against a spring.

EFFECT: expansion of assortment of restored details.
