The invention discloses a method for welding a motormeter motor coil connector. The coil connector consists of a lacquered wire and a connector. During welding, the wire ends of the lacquered wire of a coil are wound on the connector respectively, wherein the winding height of the wire ends wound on the connector is larger than half of that of the connector; and then the top part of the connectoris welded through electric arc heating. In the welding process of the invention, the temperature is extremely high and up to be 3,000 DEG C, and molten copper vaporizes the lacquerfilm of the lacquered wire instantly without any hidden trouble of dry joint; and the welding time is only tens of milliseconds, the welding speed is extremely high, the heat affected zone is small, and damages to a plastic bracket are avoided.
