One-handed 99-gear spot welder
The BFKK 99 Gear Handheld Spot Welder integrates the welding head into an ergonomic body so a single hand can complete small pack assembly. It targets battery repair professionals and DIY enthusiasts who work with cylindrical cells such as 18650, 26650 and 36650 formats. The replaceable pin design lowers consumable cost for repeated jobs.
Dual-mode LCD control under load
A colour LCD shows real-time temperature, preheat time, trigger time and power level across 99 gears. Automatic mode intelligently matches parameters for phone or Bluetooth battery tabs while manual mode gives thumb-button control for precise 0.1 to 0.2 mm nickel-plated sheets. The screen highlights the active mode icon so the operator never guesses the setting during sustained sessions.
Safety alerts and contact discipline
An automatic red-light alarm triggers when cell voltage drops below 3.2 V, cutting the weld pulse to prevent over-discharge. A blue-light warning activates at 65 degrees to guard against overheating. Reliable welds require both pins to contact smooth, clean material simultaneously at a recommended 60-degree approach angle, ensuring current flows only when the joint is ready.
