Mini spot welder 99 adjustable levels for Li ion batteries

🔋 Spot welding machine for cylindrical and NiMH batteries – High precision Optimize your welding work with this high-power spot welding machine, specially designed for cylindrical Li-ion and NiMH batteries, as well as nickel plates. With a maximum current of 1700 A and 99 adjustable power levels, produce strong and aesthetic welds, even for thousands of consecutive points. Main features: ✅ High power and precise welding Welding based on high current and high temperature, allowing the nickel to quickly melt and cool for strong and clean points. Power adjustment 0 to 99, for perfect control of each weld. ✅ Compatible with many batteries Designed for 14650, 17490, 21700, 26650, 32650 and other cylindrical Li-ion or NiMH batteries. Suitable for welding 0.1-0.3mm nickel sheet.✅ Advanced control card Equipped with 5 MOSFETs, with the possibility of adding additional MOSFETs for DIY enthusiasts. Real-time digital display of power levels for easy reading and precise adjustment. ✅ Robust welding gun Thick copper gun with copper/alumina tip, ensuring high conductivity and durability. 10 AWG cables made of high temperature wire, flexible and resistant to twisting, for sensitive and safe welding. Cold-pressed copper connectors for large contact area and reduced internal resistance. ✅ Safety and protection Transparent housing option to protect the electronic board and prevent short circuits while allowing full visibility. ✅ Important Notes Do not use with switching power supply, transformer, charger or external battery other than specified.Specifications: Name: Spot welding machine Material: PCB (electronic board) Type: With or without housing (optional) Working voltage: 6.5–16V Working current: <20mA Standby consumption: <0.5mA Recommended working temperature: -10°C to 60°C Voltage: 12V Welding current: max. 1700 A Welding thickness: 0.1–0.3 mm Product dimensions: 90 × 60 mm Packaging dimensions: 120 × 120 × 20 mm Packaged weight: 180 g Package contents (without housing): 1 × Control board 2 × Input wires 1 × Welding gun 2 × Heat shrink tubes 6 × Screws 1 × Nickel foil 1 × Manual instructions
