PROBLEM TO BE SOLVED: To provide arc welding equipment that facilitates an operator's judgment on welding abnormality or normal/defective welding conditions by simultaneously displaying a command value for welding current, welding voltage and wire feeding speed, and also by switching the actual value of welding current, welding voltage and wire feeding speed. SOLUTION: The equipment is composed of a welding torch 8, a wire feeding device for feeding a wire 9 in contact with the inner face of the tip 17 of the welding torch 8, and a welding power source 4 for supplying electric power to the tip 17 and the base metal 13. The equipment is also provided with a welding current detector 30 and a welding voltage detector 31, and is characterized by the independent and simultaneous display of the wire feeding speed command value, welding current value and welding voltage value.
