Battery Spot Welder AWithZ U3, welding

18650 batteries are not cheap, purchasing new electronic equipment is expensive, and purchasing large spot welding equipment is also expensive and occupies space. Our spot welding machine can use old batteries to build new battery packs, and install unused old product batteries onto the equipment that needs to be used. Large spot welding machines cost over a hundred dollars, and our spot welding machine is half the price of theirs, small size and easy to carry.
