Product Overview

The JG-RW45A is an industrial-grade power-frequency single-pulse spot welder specifically engineered for cylindrical battery pack assembly and precision electronic hardware. Controlled by an advanced 8-bit microcomputer microcontroller, it delivers rapid single-pulse discharge for clean, robust metal fusing.

Equipped with a real-time grid voltage scanning and automatic tracking compensation system, the machine effectively eliminates false welding or spark explosions caused by line voltage fluctuations. Combined with an independent dual pneumatic welding head design, it automatically balances height differences in battery tabs to ensure consistent electrode contact pressure.

Performance & Technical Features

Microcomputer Precision Control

Driven by an 8-Bit CPU core and equipped with a 3-group 7-segment LED digital display for intuitive parameter setting and energy monitor.

Single-Pulse Ultra-Fast Discharge

Optimized single-pulse discharge control algorithms ensure rapid response and simple operation, perfect for high-efficiency nickel tab welding.

Automatic Power Grid Compensation

Real-time high-frequency grid voltage scanning provides auto-compensation from +40V to -50V, delivering consistent energy for every spot weld.

Pneumatic Dual Independent Heads

Independently adjustable pressure on left and right electrodes with internal buffers automatically balances tab height differences for uniform contact resistance.

Plug-and-Play Control Module

Modular plug-and-play control box structure simplifies system maintenance, component upgrades, and troubleshooting.

Safety Protection & Alarm

Integrated overheat protection and failure auto-alarm functions immediately shut down system discharge, resisting strong external electromagnetic interference.
