    • A portable wire feeder for providing welding wire and welding current to a welding operation includes an input electrically connected to a power source. An output is electrically connected to the input to receive welding current delivered to the input from the power source and to provide the welding current and welding wire to the welding operation through a guide hose. A motorized wire feeding system includes a motor and a feed roll driven by the motor to direct the wire from a wire supply to the output for provision of the welding wire to the welding operation through the guide hose. Power for the motorized wire feeding system is drawn from the welding current passed from the input to the output. A grounding assembly nonattachably contacts a work piece of the welding operation to electrically ground the power drawn from the welding current directly to the work piece.
    • 用于向焊接操作提供焊丝和焊接电流的便携式送丝器包括电连接到电源的输入。 输出电连接到输入端以接收从电源输送到输入端的焊接电流,并且通过引导软管将焊接电流和焊丝提供给焊接操作。 电动送丝系统包括电动机和由电动机驱动的供给辊,以将电线从电线供给到输出端,以通过导管提供焊丝到焊接操作。 电动送丝系统的电源是从输入到输出的焊接电流引出的。 接地组件不可接触地接触焊接操作的工件,以将从焊接电流引出的功率直接电接地到工件。
