PROBLEM TO BE SOLVED: To provide equipment and method for efficient welding simple in use. SOLUTION: A wire feed speed selector 10 generates a control signal based on a selected wire feed speed. The generated voltage signal is transmitted by a line 12 to a microprocessor 20, a welding power source 100, and a function generator 90. The microprocessor 20 converts the received signal into a control voltage sent to a wire feed speed motor 30 along a line 22. The wire feed speed motor drives a wire roller 60 and feeds a consumable wire electrode 50 from a wire reel 40 to a welding gun. The function generator generates the specific waveforms for the arc welding voltage and/or current directed respectively toward the welding gun and an electric contact 70 of a workpiece 80 to the power source 100 along lines 102 and 104.
