High Precision Spot Welding Equipment, Fine Focus for Small Joints, Consistent Spot Size for Battery Manufacturing

This machine adopts an upgraded closed-loop energy feedback control system. It automatically monitors grid voltage fluctuations in real time and performs dynamic energy compensation. Unlike traditional welders with unstable pulse output, this equipment ensures identical energy release for every single welding spot.

Welding spots are uniform, flat and dense, with consistent fusion depth and tensile strength. It effectively eliminates spark splashing, black welding spots, virtual welding and insufficient welding penetration, greatly improving the overall qualification rate of battery packs.

Equipped with a high-precision multi-joint free swing arm, the welding head supports omnidirectional displacement and arbitrary angle positioning. Its large working coverage and flexible stroke easily adapt to densely arranged battery cells, multi-row modules, high-height battery assemblies and complex irregular battery pack structures.

The vertical downward pressure welding structure ensures vertical stress on each welding point, avoiding offset welding, oblique welding and poor contact caused by manual operation errors. It significantly improves welding accuracy and batch production consistency.

The device is equipped with an industrial-grade high-definition color touch screen with a visualized, intuitive operation interface. All core welding parameters, including preheating power, main welding power, pulse times and welding delay, can be adjusted digitally and precisely.

It supports storing a large number of personalized welding process formulas. Customers can save exclusive parameters for different material thicknesses and conductive strip specifications. One-click switching enables rapid production conversion between different battery products, helping factories achieve standardized and streamlined production management.

By adopting millisecond-level instantaneous pulse release technology, welding heat is highly concentrated only on the welding contact point. The heat-affected zone is extremely small, preventing thermal damage to battery cell shells, insulating paper and internal electrolyte.

This low-temperature welding feature protects battery core performance, avoids battery capacity attenuation and potential safety hazards caused by overheating, and extends the overall cycle life of assembled battery packs.

Built with a high-power silent cooling fan and multi-layer rapid heat dissipation channel structure, the core power components maintain low-temperature operation for long periods, effectively solving power attenuation and equipment overheating during high-frequency continuous welding.

The machine supports long-term 24-hour uninterrupted industrial operation with stable performance and strong anti-fatigue capability, fully adapting to the high-intensity continuous production requirements of modern battery factories.

Integrated with multiple industrial safety protection mechanisms: over-current protection, over-voltage protection, over-temperature protection, short-circuit automatic power-off and overload protection.

Once abnormal working conditions occur, the system automatically cuts off power and triggers an alarm to prevent equipment failure, battery burning and operational safety accidents, providing comprehensive safety assurance for production workshops and operators.
