DIY Spot Welding Tool Welding Machine Spot Welder 18650/32650 Battery with Case

Comes with a charging control module, which can charge battery through USB port, and is fully with 0.1mm-0.15mm internal nickel-plated sheet to weld multiple solder jointsIt is precisely controlled by Single Chip Microcomputer Program without flipping switch.Self-transporting with a charge control module, which charges battery through USB port.It is equipped with 3.7-4.2V 5000MA power lithium battery, the discharge rate is 65C, and output capacity is about 300A.Through output of MOS tube, this energy will be concentrated on tip of soldering pen, and nickel sheet will be firmly fused with battery by means of short-circuit heating. All this will happen in a few milliseconds, completely freeing your fingers or pedals.Installation steps and matters needing attention:1. to operate this product, you need to have considerable electrical knowledge. Do not short-circuit or reverse electrodes, otherwise 300A short-circuit current will make you doubt your life.2. The copper ear of black soldering pen is connected to upper surface of circuit board by M5 screws, and copper ear of red soldering pen is connected to positive electrode of battery (the back of circuit board)4. Fully charge through USB cable after assembly (in order to the durability of battery, we set a lower charging current, the charging process is about 4 hours, the red light is on when charging, and light is fully turned to green)5. After battery is connected, the circuit board defaults to on state and automatically shuts down after a delay of about 10 minutes. Press switch to turn on and select welding current intensity.6. Each time you press button, the switch will realize following functions (di-low current, didi-medium current, dididi-high current, shutdown)size:124x80x18mmMaterial:Metal + plasticcolour:Green + BlackPackage Contents:1 x High-rate power battery1 x circuit board2 x Copper soldering pen (with 10AWG wire)2 x Insulation heat shrinkable tube1 x USB charging cable1 x About 80CM 0.1x7mm nickel sheet1 x Only above package content, other products are not included.Note: Light and different displays may cause color of item in picture a little different from real thing.
