FIELD: process engineering.
SUBSTANCE: invention relates to welding automatic control devices. Proposed device comprises electrodes drive with built-in controlled motor, motor rpm transducer 3, arc length setting device 8, adder 9 wherein first and second inputs are connected with outputs of transducer 4 and setting device 8. In compliance with this invention, it additionally incorporates adder 6 with its second and fourth inputs connected with outputs of arc length setting device 4, rpm transducer 3, respectively, and with third input of adder 9, relay controller 7 with insensitivity zone with its output connected with first input of adder 6 with its output connected to drive motor input.
EFFECT: faster operation, higher efficiency and reliability.
