ABSTRACT:
It is an object to provide an arc welding apparatus capable of causing an operator to easily decide a welding abnormality and the quality of a welding condition by simultaneously displaying a welding current command value, a welding voltage command value and a wire feeding speed command value and switching and displaying an actual welding current value, an actual welding voltage value and an actual wire feeding speed.There are provided a welding torch (8), a wire feeding device for feeding a wire (9) in contact with the internal surface of a chip (17) of the welding torch (8), a welding source (4) for supplying a power to the chip (17) and a base metal (13), a welding current detector (30) and a welding voltage detector (31), and a wire feeding speed command value, a welding current value and a welding voltage value are displayed independently and simultaneously.
