Integrated Design for Efficiency: The spot welding pen is an integral part of a spot welding system, designed to work seamlessly with an integrated spot welder. Please note that it cannot function independently, ensuring a specialized tool for precision welding tasks. _x000D_ 2. Optimized for Battery Assembly: Specifically tailored for 18650 battery spot welding, this mini spot welder is built for long-term work and efficiency enhancement. Constructed with thickened copper bars for rapid heat dissipation, it boasts a clean and attractive appearance, making it ideal for assembling battery packs. The copper strips are thoroughly cleaned with strong acid and protected to ensure their brightness and durability. _x000D_ 3. Independent Spring Action: Equipped with dual retractable springs in the handle, each welding pen operates independently, providing moderate pressure control. This feature prevents the common issues of imbalance in welding pressure that leads to weak welds and excessive sparking, thus enhancing work efficiency. It's particularly suited for batch spot welding production. _x000D_ 4. Built-in Trigger Switch: The handheld battery spot welder comes with an internal trigger switch, allowing for single-handed operation without the need for a foot pedal. This significantly increases work efficiency, making it a breeze for users to operate the tool, especially beneficial for mass production environments. _x000D_ 5. Ergonomic Design: Designed with a pen-style grip, the automatic trigger welding machine allows for comfortable handling, even during extended periods of work. The design ensures that users with shorter palms can easily touch a large area of the battery surface without getting fatigued, making it perfect for batch production. _x000D_ _x000D_ Specification: _x000D_ Origin: Mainland China _x000D_ Material: aluminum-copper alloy + components _x000D_ Color (optional): Black/Blue/Red _x000D_ Working voltage: 4-12V _x000D_ Current: 800A _x000D_ Type: Integrated spot welding pen _x000D_ Style: DIY _x000D_ Product size: 125.00x41.00x15.00mm/4.92x1.61x0.59inch _x000D_ Gross weight: 250g _x000D_ Scope of application: battery, circuit board, etc. _x000D_ _x000D_ _x000D_ Note: _x000D_ Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures.
