    摘要: An arc welding apparatus includes means for controllingly supplying an output current to an arc-producing electrode, an output current setting unit for controlling the supplying means, means for feeding a filler wire, and means for applying voltage to the filler wire. A first function generator is connected between the output current setting unit and the feeding means for producing an output which is a function of an output current setting and which is delivered to the feeding means to control the rate at which the filler wire is fed. A second function generator is connected between the first function generator and the applying means for producing an output which is a function of the output from the first function generator and which is fed to the applying means to control the voltage applied to the filler wire. The second function generator may be connected between the output current setting unit and the applying means for issuing an output which is a function of the output current setting to the applying means to control the voltage applied to the filler wire. Therefore, the output current, the rate of feed of the filler wire, and the wire voltage can be adjusted solely by the output current setting unit.
