DIY Portable 12V Battery Spots Welder Pen Model PCB Circuit Board Control Welding Machine 18650Energy Storage Spot Solder

Foreword: Thank you for your attention. This product is a semi-finished circuit board. You need to have certain electrical knowledge and hands-on ability, and you need to prepare some necessary tools such as pliers, screwdrivers, soldering irons, etc Contains: 1 main circuit board, 1 buzzer, 2 10 AWG input wires, 12 AWG output wires including 2 solder pens Used for welding 18650/26650/32650 lithium batteries, etc. Advantages: portable, stable and reliable. Users need to bring their own 12V battery to supply power, and the welding current is about 90A ~ 150A. It is more than enough for common 0.1mm ~ 0.12mm nickel plated welding. After several generations of product updates, now it is even upgraded to automatically trigger welding, freeing the fingers of the button. System voltage: 12V-14.6V Working current: 90-200A Battery recommendation: 20-45ah Lead-acid battery with good performance and small internal resistance 3.5-5.5ah 45C 3S aeromodel lithium battery pack 30-35ah capacity 18650 battery pack The battery pack that can start the car can basically meet the power supply requirements of this circuit Function introduction: This circuit with 12V battery will become an energy storage spot welder for welding nickel plates such as lithium batteries and nickel-chromium batteries. According to different configurations, the welding thickness can be about 0.1MM-0.15mm. By replacing the thicker wire (10 square), it can barely weld 0.2MM thickness. After all, this device is geared towards electronics enthusiasts, and the frequency of use will not be very high, so it can also use 0.1-0.15 solder 2 to replace thicker nickel pieces.
