Gantry Transistor Spot Welding Machine
Semco SI-MWN-4000A/6000A/9000A

About the product: This transistor spot welder machine is used for welding the cells with high quality. With self-check and contrast function, it can make sure that each spot is up to standard.

Product Features:

  • The constant voltage and constant voltage charging are safe and smooth, and the voltage and current sampling output of the device is controlled through the four-wire system connection for soft start, so as to make a safe and smooth transition in the constant voltage and constant voltage charging process to avoid the occurrence of peak damage to the battery. 

  • High-precision calibration: charging current, discharge current, charging voltage and discharge voltage are all calibrated by agilent with high precision to ensure the accuracy of current within 1% and voltage within 0.5%.
