801B 11.6 KW Mini Portable Battery Spot Welder – Precision Pulse Welding Equipment for 18650 & 21700 Lithium Battery Pack Building

801B Battery Spot WelderFeaturing Capacitor Energy Storage Pulse Welding Technology combined with millisecond pulse welding, the 801B spot welder delivers powerful, reliable performance. It’s widely used for lithium battery pack building/maintenance and common metal welding—compatible with stainless steel, iron, nickel, brass, titanium, molybdenum, and more.Product ParametersPower Adapter Input: AC 100–240V 50/60Hz | Output: DC 15V 2AMachine Input: DC 15V 2A | Charging Time: 15–25 minutesOutput: Welding Voltage 5–5.8V, Welding Current 500–2000A (pulse)Maximum: Welding Power 11.6KW, Welding Energy 119JPulse Time: 0.1–10ms | Welding Power Adjustment: 0–99Welding Mode: AT/MT | Pulse Delayed Time: 20–50msNickel Welding Thickness: 0.05–0.35mmNoticesUse a wall socket to ensure stable power supply.Adjust the pressure regulator to appropriate parameters for optimal welding results.

• High-Power Energy Storage Welding: Equipped with two super capacitors for energy storage and a stable pulse spot welding power supply. Boasts a maximum pulse welding power of 11.6KW, easily welding 0.35mm nickel-plated sheets and 0.3mm pure nickel—ideal for lithium battery pack building.
• Two Welding Modes & Tools: Comes with a detachable rocker arm press-down welding tool and a portable mobile spot welding pen, adapting to battery packs of different sizes. Features "AT/MT" dual welding modes for easy, efficient completion of welding tasks.
• Mini Portable & Wide Voltage: Compact size and lightweight design for easy transport. Supports 100–240V wide voltage input, usable anywhere needed. Unlike traditional AC spot welders, it causes no circuit interference or tripping issues.
• LED Screen for Precise Control: Adjust pulse welding power (range: 0–99) via two buttons, with real-time display on the panel’s LED screen (showing welding power, capacitor voltage, actual welding current). Enables accurate judgment of spot welding issues for optimal results.
• Long-Lasting Low-Temp Operation: Adopts capacitive energy-gathering pulse technology with low power consumption, supporting up to 12 hours of efficient welding. The spot welding pen stays at around 30°C, allowing long-term use without overheating—no extra protection needed.
