Zusammenfassung:	PURPOSE: An arc welder equipped with a gas pulser is provided to reduce a working space and labor force required for welding work by integrally forming the gas pulser and a welding power supplying unit with the arc welder. CONSTITUTION: An arc welder includes a welder case(100), a control unit(110) installed in the welder case(100), and a gas agitator(160). The gas agitator(160) periodically supplies shield gases. The control unit(110) applies welding power between a base material and a torch and supplies control driving voltage in order to control an operation of the gas agitator(160). The control unit(110) includes a three-phase transformer(110), a rectifying section(115), a power breaker(113), a key input section(180), a three-phase control transformer, a welding current controller(123), a shield gas control circuit(150) and a display unit(170).
