Automatic trigger spot welding pen for 18650 battery

It is not possible for a common one-piece spot welding pen to fail to achieve pressure balance between the two welding needles, resulting in a weak weld, large sparks, and low work efficiency. This spot welding pen comes standard with a pair of efficient Japanese concentric ball needles. It has a clean appearance and rapid heat dissipation. It is suitable for battery assembly. The brass bars are cleaned and protected with a strong acid to ensure their shine. The handle has double springs for expansion and contraction, and each welding pen is independently extendable, with moderate force control. This 18650 battery spot welding pen, suitable for long-term use, improves work efficiency and is made of a thick brass bar. Features: 1.
