【High Efficiency】Its powerful copper motor can guarantee a maximum thrust of 8000N, with stable output, uniform glue output, and no agglomeration. Compared to the manual caulking gun, it only needs to be filled with caulking material and pulled the trigger. The longer gun tube also allows you to work without bending down, saving you a lot of time and energy 【Build to Last】The exquisite aluminum, copper, plastic, and blackening treatment make the product wear-resistant, corrosion-resistant, and sturdy, so it can withstand the test of time well. 【Strong Endurance】Two 2000mah lithium batteries with battery indicator lights allow you to apply 80-100 sticks of glue at once (each), and require less charging time (each is 2 hours), so you can use them alternately without frequent charging, improving efficiency 【Safe to Use】The 100-250V wide voltage, overcurrent protection, undervoltage protection, over temperature protection, and charge-discharge protection, as well as a lever lock, can effectively ensure safety during operation, so you can use it with confidence 【Simple and Convenient】6-speed adjustable speed can optimize flow rates of 0-14mm/s or 0-33in/min. The variable trigger can also control the flow rate, allowing you to better match the speed with the application. The cruise control button can achieve uniform glue release for a long time, while the convenient 360 ° rotation of the gun tube can provide better performance at corners. The replacement of the adhesive head is also very simple and convenient., Weight: 7.9 pounds, Manufacturer: YEJYISTORE
