About this item

5 high-power MOS components are used in the circuit design, along with MOS boost circuit drive to guarantee stability. The circuit includes large current control, redundancy, and low failure rate. Additionally, there are 2 large filter capacitors, an anti-interference MCU for stable performance, and 8AWG silicone welding wire. The portable design makes cellphone maintenance easier when on the go.
【Adjustable Welding Strength】: With a high power output design, the encoder flexibly adjusts the welding strength, easy to find a more suitable gear for different materials, the welding process is more accurate and the welding effect is more complete. Suitable for continuous welding of thousands of points on nickel sheets and nickel-plated sheets.
【Support Input Type】: Supports voltage of 7V to 14V, current of more than 200A. Suggested power input of 12.0V 20A-200A auto starters, 3 series -6 series supercapacitors, and 3S 5000mAh or above aviation model batteries.
【Working Principle】: The welding process is based on the principle of high current and high temperature, fast melting part of the nickel sheet, and cooling, which can fully meet the requirements of a small spots welding machine, stable quality, solid welding, and no tube frying.
【OLED Display】: More intelligent, accurate, and humane to use, the adjustable digital display clearly shows battery voltage, current size, welding pulse, interval, and number of spotwelds at a glance.
