The utility model relates to an automatic welding machine for a static contact plate of a circuit breaker. The device comprises a rack, a workbench arranged in the rack and a center rotary disc arranged on the workbench. A wiring board feeding station, a coil feeding station, a static contact feeding station, a feeding detection station, a correction station, a first welding station, a second welding station, a discharging station and a discharging detection station are sequentially arranged on the periphery of the center rotary disc, and workpiece clamps corresponding to the stations are fixed to the center rotary disc. According to the utility model, the feeding detection station, the correction station and the discharging detection station are arranged; according to the automatic welding device, whether the workpiece clamp clamps the workpiece or not can be detected, meanwhile, the clamped and inclined workpiece can be corrected, the product quality is improved, in addition, the discharging detection station is arranged behind the discharging station, whether discharging is completed at the discharging station or not can be detected, and the phenomenon of repeated welding is avoided.
