  • Pneumatic spot welding:
  • The pneumatic spot welding head adopts a buffer design, the pressure of the two welding needles is independently adjustable, and the adjustment is convenient. When the left and right electrodes are not at the same height or there is a slight height difference between the left and right sides of the battery, the force of the two electrodes is still balanced, and the welding quality will not be affected.

  • Built-in Compressed Air Pump:
  • Laser alignment positioning and solder pins, lighting device, spot welding position more professional, detailed and accurate.

  • Accurate microcomputer single-chip control:
  • It can realize single-pulse, double-pulse and multi-pulse welding.
    The microcomputer inside scans the input voltage at high speed for a long time, and when the current fluctuates, the compensation data will be calculated immediately, and the welding energy will be changed, no false welding or fire explosion will occur due to voltage fluctuation, and the welding effect is consistent each time. The welding spark is small, which has little impact on the battery.

  • Large LCD display:
  • Graphical display of the current working status.

  • Automatic counting function:
  • Single-day output can be automatically counted from 0000-9999, which is convenient to calculate single-day output and improve work efficiency.
