FIELD: welding processes and equipment, namely method for controlling manufacturing equipment providing pulse feed of welding wire to electric arc zone.
SUBSTANCE: method comprises steps of applying signal to adaptive system for controlling mechanism for pulse feed of welding wire. During automatic mode in said system control signal source is operated. Source of control signal is in the form of pickup for measuring welding wire force in guiding duct of welding hose and feed stroke pickup. Pulse is generated at time moment when welding wire achieves in guiding duct energy corresponding to optimal acceleration of welding wire motion. Pulse repetition frequency is set by adjustment of force pickup, by speed of feed mechanism and by stroke set by welding wire feed stroke pickup.
EFFECT: simplified control circuit, regulation of stroke of welding wire feed and therefore of size of drops of electrode metal transferred to welding bath.
