Abstract

PURPOSE: To stabilize a welding by providing a current variation factor detecting means and output current control means and by increasing as the time elapsing the amplification of a signal amplifier circuit as well from the time when the arc load transfer to a short circuit state, etc.
CONSTITUTION: The secondary coil 9 is provided as a current variation factor detecting means on a DC reactor 8 and the voltage induced on the coil 9 is used as the signal corresponding to the variation factor of the output current I. When the output current I is increased, the ON time intervals of a switching element 5 is reduced and in the reverse case,increased to hold the control function of the current variation. Instantaneously with the arc load 12 moving to the short circuit state from the arc state or to the arc state from short circuit state the amplification is increased as the time elapses via the delay element of an operational amplifier IC2. the welding is stabilized because of the prevention from the spatter generation and arc cut being enabled.
