Claims

[Scope of utility model registration request]

a pulsed arc power supply device that alternately supplies a base current for sustaining an arc to a welding load consisting of a consumable welding wire and a base metal and supplies a pulsed current with a pulse width shorter than the supply period of the base current; a wire feed speed control device that outputs a feed control command signal for the wire by arithmetic processing of a detection signal of the voltage applied to the load and a setting signal for setting the arc length; In a pulse arc welding machine equipped with a wire feed motor that controls a feed speed, the wire feed speed control device includes a detection signal forming means that divides the voltage applied to the load to form the detection signal; constant voltage control means for constant voltage control of the detection signal to the voltage when the base current is supplied when the applied voltage of the load is higher than the voltage when the base current is supplied; A pulse arc welding machine comprising an operational amplifier that operationally amplifies the addition signal and outputs the feed control command signal.
