1. , a kind of directly electric spot-welding machine of welding lacquered wire, form by the main frame of soldering tip, a power supply regulating and controlling effect with by head three parts that welding head holder, soldering tip pressure-regulating device constitute, it is characterized in that soldering tip makes two parallel poles with refractory metal, one deck is arranged as the bonding insulation viscose glue that is connected and insulate and separate between the electrode, mutual ohmic contact between two parallel pole ends, and other part mutually insulated;

  • Main frame is by pulse amplitude prewired circuit (21), pulse duration prewired circuit (22), pulse duration timing circuit (23), drive circuit (24), power switch circuit (25), feedback circuit (26), low-voltage power circuit (27), high-voltage power circuit (28) and high-voltage control circuit (29) are formed, its annexation is;

    pulse amplitude prewired circuit (21) is through high-voltage control circuit (29), connect power switch circuit (25) behind the high-voltage power circuit (28), pulse duration prewired circuit (22) is through pulse width timing circuit (23), connect power switch circuit (25) behind the drive circuit (24), power switch circuit (25) one tunnel is through feedback circuit (26) then, another road connects soldering tip (1) behind pulse transformer (30), feedback circuit (26) respectively with pulse amplitude prewired circuit (21), high-voltage control circuit (29), drive circuit (24), pulse transformer (30) output connects, low-voltage power circuit (27) respectively with pulse amplitude prewired circuit (21), high-voltage control circuit (29), high-voltage power circuit (28), pulse duration prewired circuit (22), pulse duration timing circuit (23), drive circuit (24) connects;

    The soldering tip pressure-regulating device by adjusting screw(rod), be attached to adjusting nut on the adjusting screw(rod), be enclosed within the spring on the adjusting screw(rod), spacing card is formed.
