The invention discloses a double-iron-wire feeding device on an automatic wire guiding machine for electrowelding. The double-iron-wire feeding device comprises supporting seats, cutting-off devices and clamps, wherein the supporting seats, the cutting-off devices and the clamps are sequentially arranged in the metal wire conveying direction; the supporting seats are used for supporting metal wires; the cutting-off devices are used for cutting off the metal wires; and the clamps are used for tightly clamping the metal wires. Feeding slide blocks capable of reciprocating in the metal wire conveying direction are further arranged between the supporting seats and the cutting-off devices correspondingly. The feeding slide blocks are connected with a drive device driving the feeding slide blocks to reciprocate. Feeding inlets are formed in the feeding slide blocks correspondingly and can be aligned with and close to corresponding punched holes in the cutting-off devices when the feeding slide blocks reciprocate. According to the double-iron-wire feeding device on the automatic wire guiding machine for electrowelding, the rear section to-be-welded metal wire can be accurately fed into the corresponding punched hole of the corresponding cutting-off device after the front section metal wire is clamped, welded and cut off so that the metal wires can be fast and continuously clamped and welded.
