Multi-protections Spots Welding Machine Lithium Battery Welding Device Built-in Welding Ammeter with Charging Pal Function DIY Complete Kit for 0.25mm Nickel Plated Sheet and 0.15mm Pure Nic

Working Principle: It controls the two high-rate lithium batteries through a program in the built-in microcontroller, and precisely outputs the pulsed energy to generate the high temperatures in a very short time. After quick cooling, the nickel-plated sheet and the battery are fused together to complete the welding process. Digital Display: Equipped with a digital display, the welding current, pulse time, pulse interval, number of continuous spots welding times and other parameters can be
