MCB Welding Machine For Bimetal, Arc Runner and Terminal

Equipment Overview

The MCB Welding Machine For Bimetal, Arc Runner and Terminal  is an advanced automated solution designed to perform simultaneous welding of three critical components—bimetal strip, arc runner, and terminal—within a single cycle.

Unlike conventional processes that require multiple welding steps, this machine uses a synchronized positioning and welding system to join all components at once. This significantly reduces cycle time, eliminates intermediate handling, and ensures perfect alignment between parts.

Equipped with high-precision servo control and advanced resistance or medium-frequency inverter (MFDC) welding technology, the machine guarantees uniform welding quality, strong bonding, and low electrical resistance.

This solution is ideal for high-volume MCB manufacturers seeking maximum efficiency, reduced labor dependency, and consistent product performance.

Main Functions

• Automatic feeding of bimetal strip, arc runner, and terminal
• High-precision synchronous positioning system
• Simultaneous welding of three components in one cycle
• Welding parameter control (current / pressure / time)
• Multi-point welding coordination
• Weld quality monitoring (optional)
• NG detection and automatic rejection
• Automatic unloading of finished assemblies
