The invention discloses a double-steel-wire guiding device on an electric welding automatic wire guiding machine. The double-steel-wire guiding device comprises wheels, wherein totally seven wheels are arranged and are completely arranged on the same plane. Each wheel is provided with at least two circles of arc grooves for metal wires to be wound around. The first wheel, the third wheel, the fifth wheel and the seventh wheel are located on the same horizontal line, and the fourth wheel and the sixth wheel are located on the same horizontal line. The vertical distance between the bottoms of the arc grooves of the wheels located on the two horizontal lines is equal to the diameter of the metal wires. The second wheel used for tensioning is located above the position between the first wheel and the third wheel, and the fourth wheel and the sixth wheel are sequentially located below the position between the third wheel and the fifth wheel and below the position between the fifth wheel and the seventh wheel correspondingly. The double-wire guiding device can be used for guiding two strands of wires at a time, in addition, guiding is accurate and stable, and loosening and scattering of the two stands of wires can be effectively prevented.
