MOTOWELD OUTPUT OVER-CURRENT indicates output overload, likely from grounded cables, contact tip touching workpiece, or encoder cable issues. The manual's first action is: “Confirm the following content. (1) Check that the torch cable or power cable is not grounded? (2)Check that the contact tip does not contact the welding work piece? (3)Check that the encoder cable is not damaged? (4)Check if the screws of the connector terminal block are securely fastened. If the encoder cable is disconnected or the screws are loosened, the wire feeding speed becomes excessively fast and an error occurs in the wire feeding amount. Replace the encoder cable or fasten the screws of the connector terminal block.”
