Title:
CONSUMABLE ELECTRODE TYPE ARC CONTROLLER
Document Type and Number:
Japanese Patent JP2541733
Kind Code:
B2
Abstract:
PURPOSE: To quickly obtain a current detection value which coincides with a welding set value by deriving a wire feed speed reference portion, based on the output signal of a current setting device, joining both of them together and outputting as the commanding value of a wire feed speed, and feeding a welding wire to a welding base metal at the feeding speed instructed by this commanding value.
CONSTITUTION: A control means calculates a wire feeding speed fluctuation portion so that a current detection value coincides with a current set value, based on the difference of outputs of a current detector 15 and a current setting device 19. On the other hand, in the case the current setting value is fluctuated, by its new current setting value, the optimal wire feeding speed is derived from the relation of the wire feeding speed and the current set value derived in advance, and it becomes a wire feeding speed reference portion. Subsequently, the control means joins together this wire feeding speed reference portion and the wire feeding speed fluctuation portion and outputs them as the commanding value of the wire feeding speed, and a driving means feeds a wire 13 to a welding base metal 14, based on this commanding value, and allows a welding current to coincide with a desired set value.
