Abstract

PURPOSE: To prevent the fluctuation in arc length occuring in hand shaking by automatically changing welding conditions in such a way that the arc voltage in peak electric current parts at the welding is maintained at a prescribed value.
CONSTITUTION: The feed rate of a wire is determined by a command circuit 4. The set rate enters a function generator 5, is converted to voltage and is inputted to a comparator 3. When the wire is fed by welding start and an arc is generated, the detected value of an arc voltage detecting circuit 1 is inputted to a peak voltage detecting circuit 2, and is compared in a comparator 3, the differential voltage whereof enters a pulse width setting circuit 12. The command of the circuit 4 is converted to voltage by a function generator 6, and this voltage is conducted to a pulse frequency setting circuit 13. On the other hand, the welding current detected by a welding current detecting circuit 7 is separated to the current in a background period and the current in a peak period in a pulse peak period selecting circuit 9 via an amplifier 8. These are compared with the output of a peak command circuit 10 in a comparator 11 and the peak current is so controlled as to be made constant by the differential voltage.
