1、Efficient and Powerful: With dual pulse output and foot pedal welding mode, this spot welder effortlessly welds Ni strips ranging from 0.1mm to 0.3mm thickness, allowing you to complete your welding work efficiently with beautiful and elegant welds. Perfect for battery, hardware, and electronic component spot welding. 2、Excellent Performance: The spot welder controls two high rate batteries to deliver precise pulse energy, generated by the built in microcontroller program, creating high temperatures in a very short time. After rapid cooling, the Ni strip is welded to the battery, completing the spot welding process. 3、LCD Screen Display: Battery voltage level is a crucial factor affecting spot welding results. Our spot welder's screen displays the real time internal voltage of the product, allowing you to conveniently monitor and charge it in a timely manner. Please ensure the product is fully charged before first use and recharge when the screen voltage is below 7.3V. 4、User Friendly: This mini spot welder is compact and lightweight, saving space in your home. You can easily transport it to different work locations. Simply press the foot pedal switch, and after the red lights rapidly flashes three times, it outputs the current for welding, completing the process effortlessly. 5、Wide Applications: The high power output of this spot welder enables it to be used for connecting Ni strips to 18650 lithium batteries or spot welding iron sheets and stainless steel sheets. It is also suitable for fast welding of 0.1 to 0.3mm Ni plated steel strips and 0.1mm pure Ni sheets. It is an ideal choice for battery pack manufacturing and engineering repairs.
