FNIRSI SWM-20 is a portable spot welder designed for strong and repeatable joints when working with battery cells and other electronics projects. Thanks to the dual pulse, weld quality is improved: the first pulse helps remove oxidation from the surface and the second performs the welding itself, resulting in cleaner and more stable outcomes.
The clear 2.4" TFT display shows key data in real time such as voltage, temperature, and welding settings. Parameters can be fine-tuned easily using the rotary controller, and the device also supports software updates via USB-C.
The built-in battery with a capacity of 5,000 mAh can handle up to approx. 1,500 welds per charge and also allows the device to be used as a power bank for charging other devices. Removable welding tips made of 99.9% pure copper ensure excellent conductivity, efficient heat dissipation, and long service life.
Package contents: spot welder, welding tips, spare tips, USB-C cable, nickel strip, user manual.
