    Product Detail

    Equipment Overview

    The MCB Bimetal Copper Wire and Moving Contact Automatic Welding Machine is a specialized automation solution developed for the welding process of NT50 miniature circuit breakers.

    In NT50 MCB manufacturing, the connection between the bimetal strip, copper conductor wire, and moving contact plays a crucial role in determining the circuit breaker's thermal protection accuracy, electrical performance, and long-term reliability. Traditional manual welding processes often lead to inconsistent welding quality, unstable resistance values, and reduced production efficiency.

    This machine integrates automatic feeding, precision positioning, and intelligent welding control to achieve high-quality and repeatable welding results. The equipment uses advanced welding technology combined with a servo-controlled system to ensure stable welding energy and accurate positioning of components.

    Main Functions

    • Automatic feeding of bimetal, copper wires, and moving contacts
    • Precision positioning before welding
    • Automatic welding of bimetal and copper wire connection
    • Moving contact welding process
    • Real-time welding monitoring system
    • Automatic finished product unloading
    • Production data monitoring and fault alarm system
