Portable Digital Spot Welding Control Board for 18650 Lithium Battery DIY Projects

About this item

• 【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.
• 【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.
• 【Scientific Circuit Design】: Adopting 5pcs high-power MOS, MOS boost circuit drive, ensuring MOS stability, with large current control, with big redundancy and low failure rate. Paired with 2 large filter capacitors, stable-performance anti-interference MCU, and paired with 8AWG silicone welding wire. With its portable features, go out of the maintenance of cellphones is more convenient.
• 【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.
• 【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.
• Sure! Please provide the lines you'd like me to modify, and I'll help you rephrase them to maintain their meaning while avoiding duplicates.
