This compact spot welder is designed for efficient work with nickel strips, steel sheet, stainless steel, and aluminum. Dual-pulse technology improves weld quality: the first pulse helps remove oxidation from the material surface, while the second pulse delivers the energy needed for a strong and stable joint. The result is more precise welding with less sparking and better control over the entire process.
The integrated grade-A battery with a capacity of 5000 mAh provides stable high-current power and allows convenient operation without constant connection to the mains. The device also serves as a backup power source thanks to its 5 V / 2.1 A USB output, so you can use it to charge a phone or other small accessories, for example.
Operation is made easier by the color 1.8-inch TFT display, which shows important information such as voltage, temperature, pulse duration, and the number of welds performed. The spot welder also offers safety protections against short circuit, overcharge, overheating, overload, and voltage drop. The package includes electrodes with leads, nickel strip, spare welding needles, a USB charging cable, and a user manual.
