01TATTOO SUPPLIERS
Precision welding in a handheld form
A compact instrument for the workbench, this handheld tool condenses high-output welding into a pen-like form factor. It sits comfortably in one hand, ready for delicate tasks involving cylindrical batteries or internal phone components.
Designed for enthusiasts and professionals alike, it offers dual-mode operation with clear digital feedback. The device manages heat and current precisely, allowing for consistent strip welding on thin materials without the bulk of traditional equipment.


02MATERIALS
Durable ABS and PC shell
The housing combines ABS and polycarbonate, providing structural rigidity while keeping the overall weight near 395 grams. This balance ensures the tool remains manageable during extended sessions. The modular design incorporates replaceable welding needles, specifically copper bars, which can be swapped out as they wear down, maintaining performance over time.

04SAFETY
Integrated thermal protection
Internal safeguards monitor voltage and temperature to protect the power source. A red LED alerts when voltage drops, while blue warnings trigger automatic shutdown if temperatures reach 65 degrees Celsius. These mechanisms help prevent overheating and over-discharge, extending the lifespan of the built-in 3000mAh lithium-ion battery and ensuring consistent output across multiple uses.
05KIT
