14.6 kW Capacitor Spot Welder
The BFKK spot welder delivers a maximum pulse power of 14.6 kW from two built-in super capacitors. It operates on 100-240 V input and reaches welding readiness in about 5 minutes. The unit suits professionals and DIY builders assembling 18650, 14500, 21700 or LiFePO4 battery packs.
999 Adjustable Gears and Material Limits
Ninety-nine adjustable gears let you match energy to each task. The welder handles 0.6 mm nickel-plated, stainless or iron sheet, 0.3 mm pure nickel and 0.2 mm copper sheet. It is not suited for thicker plate or high-volume production lines that demand continuous duty cycles beyond the capacitor recharge rate.
60 cm Flexible Leads and Foot Pedal
The 60 cm welding leads bend freely without dragging the chassis and stay near hand temperature even on high gears. Six pairs of replacement pins are included. A 2 m foot pedal enables hands-free single-pulse operation for precise probe placement, while automatic mode starts welding as soon as the probes touch the workpiece.

Questions about this item
How do I choose a gear setting for 0.15 mm nickel strip versus 0.6 mm stainless steel?
The welder provides 999 adjustable gears; start lower for thin 0.15 mm nickel strip and raise the gear for thicker 0.6 mm stainless steel or nickel-plated sheet, testing on scrap first.
What does the 14.6 kW peak pulse power mean when I am welding 18650 cells?
It is the maximum instantaneous welding power delivered by the dual super-capacitors, enabling strong, consistent spot welds on 18650, 14500, 21700 and LiFePO4 cells without tripping the supply.
What input voltage does the 15 A charger accept and how quickly is the unit ready?
The charger works on 100-240 V and brings the capacitors to the welding-ready state in about 5 minutes, indicated by OK on the display.
