Equipment Features

1. Equipped with high-voltage testing to reliably detect short-circuited and micro-short-circuited batteries; test voltage range: 0–3 kV.
2. Alarms and rejects batteries with failed short-circuit testing or defective welds such as cold joints; defective-product counting function available.
3. Touchscreen operation.
4. Fully automatic workflow including feeding, positioning, pole group handling, high-voltage short-circuit test, intercell welding, internal resistance test, defective rejection and discharging.
5. Provided that holes are burr-free, the intercell weld shall be free of blowholes with full weld area, and the partition wall shall remain undeformed after welding. Precise positioning is guaranteed during continuous production.
6. Parameters for each individual intercell welding hole are adjustable and storable; intercell welding position adjustment is automatic and visualizable.
7. Weld tip pressure adjustable; pressure range: 0–100 kg/cm².
8. Adopts Miyachi welding system. Welding current, welding time, voltage and total power are visualizable, storable and exportable.
9. Welding cycle counter for intercell welds; the count value is visualizable, storable and exportable. The counter can be reset after replacement of welding tips.
10. Weld spot internal resistance test: DC 5 V test voltage; test current: 10–100 A.
11. One spare set of copper electrode tips supplied as standard accessory.
12. Fully digital control for unattended operation.
