High Precision MCB Welding Machine for Moving Contact & Copper Wire - China Suppliers & Factory
Equipment Overview
The MCB Welding Machine For Moving Contact and Copper Wire is a specialized automated solution designed for welding copper wire to moving contacts in Miniature Circuit Breakers (MCB), particularly for models widely used in Southeast Asia markets.
This machine integrates automatic copper wire feeding, cutting, positioning, and precision welding processes to ensure strong bonding and reliable electrical performance. It is engineered to handle flexible lead wires and small-sized moving contacts with high accuracy.
By adopting advanced resistance welding or medium-frequency inverter welding (MFDC) technology, the system ensures stable welding quality, low contact resistance, and consistent production results.
The equipment is ideal for manufacturers targeting Southeast Asia markets where use different MCB model.
