SQ-SW1 lithium battery pack 5000mAh 3S 60C with XT90 plug

Spot Welder for Batteries Product introduction

Nowadays, lithium batteries are widely used in electronic products, rechargeable batteries, electric vehicles, balance vehicles, aircraft models, ship models, electronic tools, and so on. Due to the diversity of battery shape and volume and the limitation of power supply mode, the traditional welding machine lacks flexibility. SQ-SW1 is battery powered, OLED display can show high and low voltage warnings. Using the new spot welding technology, and intelligently switching automatic or manual working mode to meet different needs. It is a flexible and efficient welding tool.

Safety Tips

1. The two electrodes and solder pins should not be touched together to avoid short circuits.
2. Pay attention to the correct wiring. Refer to the manual for the specific wiring method.
3. When using for the first time, set the welding pulse duration to 2ms and check the welding result. According to the actual welding situation, set the appropriate welding pulse duration step by step to obtain good welding.
4. If you use higher current or non-factory parts, you need to take the risk yourself.
