Portable 9000W Spot Welder for Battery Packs
This 9000W battery spot welder is built for hobbyists and technicians assembling DIY battery packs. It handles cylindrical power cells as well as smaller phone and Bluetooth batteries. The dual pulse output and 100-step rotary knob give fine control over weld strength for each cell type.
Rotary Knob Control with Dual Trigger Options
A large rotary knob adjusts gear, trigger time, mode and continuous weld count through a clear panel. Users can switch between hands-free foot pedal operation and a hand trigger for precise positioning. Intelligent thermal protection halts welding if the battery overheats, and the unit powers down after eight minutes of inactivity.
Replaces Basic Fixed-Power Welders
The 100-level adjustment replaces single-setting tools that cannot match both delicate and heavy cells. Automatic mode speeds up repetitive pack building, while foot pedal mode suits complex joints needing two-handed alignment. Buyers who need integrated jig fixtures or a wider welding thickness range should look elsewhere.
