787A+ is one of the most cost-effective model in sunkko products. It is specifically designed for battery welding (18650, 14500 battery, etc) and can be used to weld nickel strips with thickness between 0.05 and 0.15 mm for nickel plated steel or between 0.05 and 0.1 mm for pure nickel strip. With the built-in LED light, you can even work at night.
We understand that after the pack is done, the next step would be charging, which is why 787A+ is equipped with a fast charging port whose voltage and current are adjustable for your convenience.
Two ways of welding:
Fixed welding head:
You can build your battery pack with the fixed welding head, in this case, you need to adjust the pressure adjustor to make the spots more reliable and elegant.
Fixed welding head with foot pedal:
Different users may have different welding habits, so we added a foot pedal to 788H. Coordinating hands and feet at the same time will also make the long-term spot welding process not so tiring, plus the use of foot pedal during battery welding improves the precision of spot welding.
