Features   8000W high power intelligent double pulse spot welder with rechargeable internal battery, good performance and long service life.    The battery welder is designed for welding 18650 batteries and can also be used to weld nickel strips with thickness of 0.1, 0.15, 0.2, 0.25, 0.3mm.    It comes with a soldering pen with good conductivity and low contact resistance.    ABS shell material with surface anodizing technology, wear-resistant and safe to use.    Small and portable design, easy to carry around.       Specification    Color: Black    Input: 100-240V    Output: 8.4V    Battery type: lithium battery    Spot welding current:1200A    Power:8000W    Included battery capacity: 9600mA    Maximum output voltage: 8.4V    Maximum output power:8000W    Spot welding nickel tape thickness: 0.1, 0.15, 0.2, 0.25, 0.3mm (can not spot welding copper / aluminum / gold / silver)    Machine size: about 15 long * width 9.8 * height 5cm    Spot welding pen length about : 47cm       Note    The products are divided into automatic models and foot switch models, which can be selected according to your own needs.    The charger plug is divided into US regulations, and European regulations can be selected according to your needs    Our products are "rechargeable spot welders" not transformers.    The spot welding machine is used for spot welding the connecting nickel strips of 18650 lithium batteries, or spot welding iron sheets, stainless steel sheets, but not copper and aluminum.    Nickel strips are divided into nickel-plated and pure nickel. The spot welding thickness of spot welding machine is the thickness of nickel-plated, and the unit is mm (mm)    The difference between automatic and foot switch:    The automatic model has no foot switch, and the spot welding is output about 0.5 seconds after the welding pen touches the nickel tape.    For the foot switch model, you need to step on the switch with your foot. After the welding pen touches the nickel tape, it will output spot welding for about 0.5 seconds, and then release the foot switch to complete a spot welding.       List    1 x Spot welder    1 x Power adapter    1 x Nickel tape 1m    1 x Sandpaper
