<p>PROBLEM TO BE SOLVED: To improve the welding yield of an electronic component, such as a metallized film capacitor. SOLUTION: A lead wire welder for an electrical component comprises a holder 16, an axis 18 which is rotatably supported by the holder 16, and two welding electrodes 11 and 12 which are fixed on the axis 18 and are respectively made of different materials. Upon welding, the electrodes 11 and 12 are pressed to lead wires 14, which are put on electrodes 15 of a component element 13. To improve the service life of the welding electrodes, the electrode 11 is made of tungsten, and the other welding electrode 12 is made of copper tungsten. Also, by making the two welding electrode 11 and 12 formed into disks, and a welding position changed according to the arbitrary number of weldings, the service life of the welding electrodes can be improved.</p> |
