• 【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.
• 【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.
• 【Good Adaptability】With corresponding push plates and pistons, it can be used together with soft or hard glue. The common glass adhesive, silicone, and structural adhesive can be adapted and this item is not easily clamped with adhesive tape.
• 【Elaborate Design】At the moment of releasing the switch, the glue push rod will immediately retract to automatically glue back, avoiding unnecessary glue dripping and causing waste. Its automatic pressure relief function effectively utilizes the pressure relief principle and can effectively prevent glue overflow.
