• 【Dual Pulse Welding Technology】: Mini Spot Welder is equipped with synchronous dual pulses. The front pulse removes the oxide layer of the weldment, effectively reducing 90% of spatter; the rear pulse continuously outputs stable energy to ensure that the weld is uniform and firm. Dual collaboration improves welding yield and equipment durability
• 【2 in 1 Grade Power Battery + Mobile Power】: Capacitor Battery Spot Welder has 2 sets of 5000mAh A-class power cells built in, and can complete 800-1200 nickel sheet welds on a single charge (0.15mm thickness test data). Supports fast charging and can be used as an emergency power bank to power mobile phones/tablets
• 【Four-Speed Precision Power Adjustment】: Dent Puller Welder is equipped with a digital power adjustment knob, which is suitable for 0.1-0.3mm nickel sheets and welding needs of different materials. It is recommended that novices enable the 1-5 second delay mode and use it with a brass soldering pen for accurate use
• 【Full-Color Display】: The Spot Welder Machine is equipped with a 1.8in TFT LCD screen to display core parameters in real time: voltage accuracy, temperature monitoring, and abnormal conditions automatically trigger over-temperature/low voltage/short circuit processing to ensure safe use
• 【Multi-Specification Battery Welding Solution】: DIY spot welding tools are designed for battery assembly and are compatible with cylindrical batteries and square batteries. Suitable for battery pack repairs, DIY energy storage equipment and other scenarios
