250-Gear Spot Welder, Energy Storage With Double Capacitor, Double Pulse Welding, 0.3 Mm Nickel Sheet, 18650 Battery Spot Welder

Product Specifications: Voltage: 110 V–240 V (Universal) Power Settings: 250 Levels Current: 5 V; 2100 A Display: 1.8-inch LCD Spot Welding Pen Cable Length: 50 cm Temperature Control: Intelligent temperature control, keeps the internal temperature below 45 °C Instructions: 1. This product is a spot welder for supercapacitor energy storage devices. Primarily suitable for spot welding 18650 and other batteries. Available nickel strip thicknesses up to 0.25 mm, maximum welding thickness 0.3 mm. The high welding power allows welding even 0.1 mm thin copper sheets in battery packs. The amperage is increased at the main output. 2. Compatible with mobile 12V power supplies, convenient for outdoor use: Unlike transformer spot welders, supercapacitor spot welders require low current to concentrate energy in the supercapacitor for a long time. Since you don't have to worry about power supply issues, there is no impact on the power grid or potential tripping. Any 12V power supply (> 3A) provides sufficient power.
