Product information
FNIRSI SWM-10 portable 2-in-1 spot welder
FNIRSI SWM-10 is a compact spot welder with powerbank function, equipped with dual pulse technology, output current up to 1200A and a lithium battery with a total capacity of 5000 mAh. With an easy-to-read 1.8" TFT display, precise parameter adjustment and wide compatibility with various materials, the device is ideal for working with phones, cylindrical cells or powerbanks. In addition, it supports USB device charging and offers a full set of safety features.
Stability of operation
Dual-pulse technology ensures more precise and durable seals. The first pulse removes oxides from the surface of the material, while the second pulse provides operating energy, which minimizes sparking and improves joint quality. With the ability to generate up to 1200A of current, the FNIRSI welder can handle materials up to 0.25 mm thick. This allows it to work effectively with nickel, steel, aluminum and iron sheets in a variety of applications.
5000 mAh capacity
The welding machine is equipped with a Class A battery, which consists of 2 cells. This design provides a stable power supply with high current, which allows for long and efficient operation without frequent charging. The battery can also power other devices as a powerbank thanks to its 5V/2.1A USB output.
1.8-inch TFT screen
The color LCD screen provides quick access to key information such as voltage, temperature, pulse time and number of seals performed. This simplifies operation and increases control over the process.
Diverse applications
The FNIRSI SWM-10 portable 2-in-1 welding machine allows you to weld cells in phones, powerbanks, cylindrical batteries or whole packs. Thanks to its adjustable parameters, it easily adapts to different tasks.
Thoughtful solutions
The device is equipped with a USB port with a voltage of 5V and a current of 2.1A. This allows it to act as a powerbank and will prove useful as a backup power source in the workshop or on the go. The welder uses a temperature sensor and provides protection against short-circuiting, overcharging, overheating, overloading, voltage drop and other potential hazards.
Included:
- FNIRSI SWM-10 spot welder
- Electrodes with wires
- Nickel tape
- Spare welding needles
- Operating instructions
