Pressurizing Mechanism:
- Vertical pressure type with self-lubricating bearings for better performance.
- Minimizes electrode impact, preventing damage and wear.
Pneumatic System:
- Includes Japanese “SMC” solenoid valves, Taiwanese air processors, and oil-free cylinders.
- Gas storage tank stabilizes pressure.
Discharge Transformer & Welding Circuit:
- Uses Wugang silicon steel sheets, and precision copper casting.
- Soft copper tape and electrodes in series.
Main Control System:
- Mitsubishi PLC and HMI.
- Manual, automatic, and charging modes.
- Adjustable parameters via touch screen (voltage, pressure time).
Welding Controller:
- Fast charging/discharging via microprocessor.
- Compatible with old and new capacitors, it extends capacitor life.
- Protection modes for fault prevention.
- Automatic adjustment for capacitor voltage and leakage current.
- Fault detection for overcharge, discharge, and capacitor errors.
- Stores up to 5 welding specs, count 9999 welds, real-time voltage detection (error ≤ 1%).
