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 (), a wire feeding device for feeding a wire () in contact with the internal surface of a chip () of the welding torch (), a welding source () for supplying a power to the chip () and a base metal (), a welding current detector () and a welding voltage detector (), and a wire feeding speed command value, a welding current value and a welding voltage value are displayed independently and simultaneously.
