Questions about this product

How thick a nickel strip can this spot welder handle?
It welds nickel strip from 0.1 mm to 0.2 mm thick, which covers most 18650 pack builds. Output is adjustable from 100 A up to 650 A so you can dial in the pulse. Thicker strips beyond 0.2 mm are outside its rated range.
Is this welder meant for hobby use or production?
It's aimed at DIY electronics work like building or repairing 18650 battery packs. The compact size and simple controls suit makers and tinkerers, not high-volume manufacturing. It's great for power tool packs, prototypes, and swapping out dead cells.
How does it get powered and what does the screen show?
It has a built-in 5000 mAh battery that charges over USB-C at 5V, 2A, so it works cordless. The OLED screen shows your settings while you weld. That makes it easy to use on the bench or out in the field.
