SEESII Battery Spot Welder — 3360W Portable, Rechargeable with Visual Display and 99-Gear Precision

Meet the SEESII Battery Spot Welder

The SEESII Battery Spot Welder blends portability with power for DIY battery projects, on-site repairs, and outdoor tasks. A built-in rechargeable battery liberates you from cords, letting you move between workbenches, garages, or remote sites with ease and confidence.

Power, Precision, and Practical Design

Delivering up to 3360W of welding power, this tool is built for demanding quick bonds while staying compact enough for handheld use. It has been tested to weld nickel-plated sheets up to 0.2 mm and pure nickel sheets up to 0.15 mm, offering flexibility for small packs and repair work. A 99-gear fine adjustment system lets you tailor welds to different materials and thicknesses, giving you granular control over outcomes. The visual display keeps you informed about the current welding stage, device temperature, and remaining battery, so you stay oriented through each step of the process.

The dual-mode design adds versatility: auto welding handles repetitive tasks, while manual mode offers hands-on control when the situation calls for it. The handheld, cable-free form eliminates leash-like limitations, and a protective pen cover helps prevent incidental touches and protects tips during transport.
