DIY Spot Welding Machine Hand for 18650 Battery

This product is an integrated spot welding pen that needs to be used with a spot welding machine. It is just a spot welding pen and cannot be used alone.

The 18650 battery spot welding pen is suitable for long-term work and improves work efficiency. It is made of thickened copper strips. The appearance is beautiful and tidy, the overall copper bar, heat dissipation is very fast, very suitable for assembling battery packs, all copper bars are cleaned with strong acid and protected to ensure that the brightness of the copper bars is very beautiful!
The handle is retractable with double springs, each welding pen is independently retractable, and the force is moderately controlled. It will not happen that the ordinary one-piece spot welding pen cannot balance the pressure of the two welding needles, resulting in weak welding, large sparks, and low work efficiency. This problem can be solved by independent expansion and contraction of double springs, which is suitable for mass spot welding production.
Built-in travel switch, one-handed operation, no need for foot pedals, and greatly improved work efficiency. When the hand uses a pen-type handle to hold the spot welding handle, the palmar brevis muscle can touch a large area of the battery surface. During long-term work, it will not be fatigued due to the long stroke and the heavy spot welding handle, which is very suitable for mass production.
