Abstract

PURPOSE: To control the feeding of a core wire from the fed portion and fluctuated portion and improve welding performance by obtaining the fed portion of the core wire by the preset welding conditions and the fluctuated portion of the set value of the arc voltage during welding.
CONSTITUTION: Set welding current I, set welding speed V and set arc voltage Vc are inputted to a multiplier-divider 23 which in turn calculates the constant feed portion for a core wire 4 of the 1st term of the formula I. Next, the arc voltage Va during welding is detected and this is compared with the set arc voltage Vc by an addition operator 8, by which the difference Vα thereof is operated. At the same time, the voltage difference Vα, the set welding current I and the set welding speed V are inputted to a multiplier-divider 21 and based on the arc voltage difference, the fluctuating portion is obtained by the 2nd term of the formula I. At the arc voltage Va>Vc, a core wire feed motor 5 feeds the core wire and at the voltage Va<Vc the motor 5 returns the core wire.
