MCB welding machine for coil and terminal

Equipment Overview

The MCB Welding Machine for Coil and Terminal is a specialized automation solution developed for welding the electromagnetic coil and terminal connections in miniature circuit breakers.

In MCBs, the connection between the coil and terminal is essential for ensuring proper operation of the electromagnetic tripping mechanism. Poor welding quality can lead to unstable electrical conductivity, overheating, or malfunction of the circuit breaker.

This machine adopts advanced resistance welding technology combined with precise positioning and intelligent control systems to ensure stable and reliable welding performance. The equipment can accurately weld coil  to terminal components, ensuring low resistance and strong mechanical bonding.

The system integrates automatic feeding, positioning, welding, and unloading, enabling continuous production and improving overall manufacturing efficiency. With its stable performance and flexible configuration, the machine can be adapted to different MCB designs and specifications.

The equipment is widely used in MCB production lines, especially in factories producing large volumes of low-voltage circuit breakers for global markets, including Southeast Asia, the Middle East, and India.
