BDD Handheld Spot Welding Pen 12V 800A for Battery Pack Welding

The BDD Handheld Spot Welding Pen 12V 800A is a high-quality, professional-grade welding accessory designed specifically for use with external spot welding machines. This product is not a complete spot welder-it is a welding pen only and must be connected to a compatible spot welding control board or welding machine to operate.

Built for reliability, durability, and efficiency, this welding pen features a thick solid brass rod construction, providing excellent over-current handling, high heat resistance, and stable welding performance. This makes it ideal for long-term operation, mass production, and continuous battery pack assembly without performance degradation.

The double-spring internal mechanism ensures smooth, balanced pressure during welding. Each welding pin is independently retractable, allowing consistent contact force and improved welding accuracy. This design helps prevent poor welds, sparks, and inconsistent current flow that are common with standard fixed-pin welding pens.

Equipped with eccentric welding needles, the pen allows precise welding on very fine nickel strips, improving contact current and weld quality. It also includes a pair of concentric ball needles, offering flexibility for different welding tasks and materials.

The built-in lift switch enables true one-hand operation, making it comfortable and efficient for extended use without fatigue. Its ergonomic design makes it ideal for workshop environments, DIY battery builders, and professional battery pack production lines.

Designed for 12V systems and up to 800A current handling, this pen is perfect for applications such as 18650 battery pack welding, lithium battery assembly, and nickel strip welding when paired with a proper spot welding machine.
