Ansiki FS01 Spot Welder Features and Specifications
The Ansiki FS01 delivers 11 adjustable power gears across a calibrated output range, giving professional battery pack assemblers a precise energy control system that matches pulse intensity to strip thickness without guesswork. Tested weld penetration reaches 0.3mm nickel strip material — the standard thickness used in 18650 lithium battery pack construction — producing bonds that pass peel and continuity checks in production environments. The compact portable welding tool format keeps total weight low enough for extended single-hand operation, reducing fatigue during repetitive spot welding runs on multi-cell packs. Dual welding pins are spaced for consistent electrode contact geometry, which directly controls weld nugget diameter and resistance uniformity across the strip. Order the FS01 from the official Ansiki store for the best available price and the confidence of a genuine, factory-tested instrument backed by the brand.

Excellent device for welding nickel-plated plates. In automatic mode at level 11, it works perfectly. The kit does not include a charging cable, which is cheap but could have been included for this price. The device can be adjusted to specific parameters, overall it works well. I recommend it.
