9000W Spot Welder for DIY Battery Packs

This 9000W battery spot welder is built for hobbyists and technicians assembling DIY battery packs. It handles cylindrical power cells, mobile phone batteries and button batteries with a 0.1-0.3mm welding range. The portable unit suits workshop or field use where mains-powered machines are impractical.

Check Power Source and Trigger Preference

Verify that your workspace can supply the energy this welder demands and decide whether you prefer the foot pedal for hands-free operation or the hand trigger for precise single spots. The automatic shutdown after eight minutes of inactivity means the unit will power down during long pauses, so plan workflow accordingly.

Thermal Protection Manages Sustained Use

Built-in temperature monitoring stops the trigger and alerts you when overheating is detected, letting the unit cool before the next weld. Ultra-low power consumption extends standby time between sessions, while the 100-level rotary knob lets you dial power down for delicate cells or up for thicker tabs during extended production runs.

Questions about this item

What comes in the box and what do I need to buy separately?

The unit includes the spot welder with rotary knob control, foot pedal trigger and hand trigger for dual operation modes. Welding electrodes, battery cells and nickel strip for pack building are not included.

Which welding thickness range should I select for my cells?

The machine is rated for 0.1 to 0.3 mm materials. Choose the lower gears for thin phone or button batteries and higher gears for thicker cylindrical power cells within that range.

How does the 9000 W rating translate to actual spot welds?

The 9000 W peak power drives the dual pulse output; the rotary knob lets you set 100 precise gear levels and trigger time so each weld delivers the right energy for 0.1–0.3 mm nickel strip without overheating.
