Features:

 * Optimal voltage / current: 12V / 150A. Support welding 0.1-0.15mm nickel plate.

 * 5×300A ultra-low-resistant MOS tubes, feature stable and strong current of up to 1500A.

 * Provide 5-gear output power adjustment via button, meeting different welding needs. 

 * Upgraded V7 circuit layout, greatly reduces internal resistance, making welding firmer. 

 * Newly add 4 screw holes and 2 thickened bar coppers, more convenient, stable and reliable. 

 * 25V high-frequency capacitor, low internal resistance, makes the power supply more stable. 

 * 35cm ultra-long welding pen (including wire) and soft silicone wire, allow you to weld flexibly and freely, easier to operate.

 * 10AWG wire and ODSC welding needle, ensure large-current-passing capacity and durability.

 * Anti-slip screws and pure-copper joints, reduce internal resistance and increase current-passing area.

 * Widely suitable for welding 18650 / 26650 / 32650 lithium battery and other cylindrical lithium batteries. 

 Note:

 1. Power Gear Switching: After connecting to the power supply, long press the function button to boot up, and it defaults to 1 gear. Output power will increase by 1 gear after pressing and holding the key for 2s. The time of LED-indicator flashes is keeping with the corresponding gear. For example, When it is 3 gear, LED-indicator will flash for 3 times. 5 gear is the strongest output power. 

 2. Welding tip: Put the nickel sheet on the surface of the battery electrode that needs to be burst, tilt the nickel sheet with one pen, then tilt the nickel sheet with another pen. The welding will be triggered after about 0.5s when the control board detects that the pen is placed. If the solder joint is black, turn down the gear. If the melting point is too small, increase the gear.

 3. 12V-15V voltage and 100-200A current are recommended. It doesn't work with working current of ＜100A.
