FNIRSI SWM-10 is a compact spot welder with powerbank function, equipped with double pulse technology, output current up to 1200A and lithium battery with total capacity of 5000mAh. With an easy-to-read 1.8" TFT display, precise parameter setting and wide compatibility with different materials, the device is ideal for working with phones, cylindrical cells or power banks. It also supports USB device charging and offers full security functions.

Stability of operation
Double pulse technology provides a more precise and durable seal. The first pulse removes oxides from the surface of the material, while the second pulse provides operating energy that minimizes sparking and improves bond quality. The FNIRSI welder, which can produce up to 1200A of current, can handle materials with a thickness of up to 0.25 mm. This allows you to work effectively with nickel, steel, aluminum and iron sheets in various applications.

5000 mAh capacity
The welding machine is equipped with a class A battery consisting of 2 cells. This design provides a stable power supply with high current, which allows long and efficient operation without frequent charging. Thanks to the 5V/2.1A USB output, the battery can power other devices as a power bank.

1.8 inch TFT screen
The color LCD screen provides quick access to the most important information, such as voltage, temperature, pulse time and number of seals performed. This simplifies handling and increases control over the process.

Various applications
The FNIRSI SWM-10 portable 2-in-1 welding machine allows you to weld the cells of phones, powerbanks, cylindrical batteries or entire packages. Thanks to its adjustable parameters, it easily adapts to different tasks.

Thoughtful solutions
The device has a USB port with a voltage of 5 V and a current of 2.1 A. This allows it to function as a power bank, proving useful as a backup power source in the workshop or on the go. The welder uses a temperature sensor and provides protection against short circuits, overcharges, overheating, overloads, voltage drops and other potential hazards.
