Home improvement spot welder promising neat, repeatable joins for battery and electronic work, the Seesii Battery Spot Welder. Weekend builders gain confidence and waste less time reworking joints thanks to clear controls and hands-free foot-pedal operation. Is it the right choice for hobbyists and small workshops needing a portable welding solution?
⚡ At a Glance
- • Welding Precision: Capable of welding 0.1-0.3mm nickel plates with tidy, consistent weld points
- • Best for: DIY battery pack makers, hobbyists and small electronics repair tasks
- • Not ideal for: High-volume industrial production requiring continuous, large-scale throughput
Portable 8000W spot welder with dual pulse output, foot pedal and auto modes. LCD shows internal voltage in real time to aid charging and operation.
Consistent, attractive welds – with dual pulse output and pedal welding mode
Dual pulse output fires two controlled energy bursts to concentrate heat briefly on the joint while pedal welding mode allows the operator to time pulses precisely. Welding work handles 0.1-0.3mm nickel plates, producing compact weld nuggets after rapid cooling.
Repeatable joins reduce the chance of weak connections when assembling battery packs, and pedal control helps achieve steady results even for beginners.
Fast cycle times – thanks to 8000W power and microcomputer pulse control
An 8000W high-performance configuration uses two ultra-high performance batteries and a built-in single-chip microcomputer to emit precise pulse energy. High temperature is generated in a very short time, then the joint cools rapidly to form the weld.
Quick welds speed up small production runs and save time when making multiple cells, while microcomputer control keeps pulses consistent from one weld to the next.
Clear status and safer use – with LCD voltage display and charging guidance
An LCD screen displays the unit's internal voltage in real time, enabling users to monitor battery level. Manufacturer guidance advises fully charging before first use and recharging when the screen voltage falls below 7.3V.
Visible voltage information helps avoid low-voltage operation that can impair welding performance and encourages timely charging for reliable results.

❓ Frequently Asked Questions
Q: What thickness of nickel can the welder handle?
A: The welder is designed for 0.1-0.3mm thick nickel plates, suitable for common battery tab work.
Q: How do the foot pedal and firing sequence work?
A: Pressing the foot switch causes a rapid red-light flash three times, then a single power output completes the welding cycle.
Q: How should the unit be charged and monitored?
A: The LCD displays internal voltage in real time; charge fully before first use and recharge when the screen voltage falls below 7.3V.
🏆 Our Verdict
The Seesii Battery Spot Welder suits DIY battery pack builders, hobbyists and small workshops that need neat, repeatable welds. Dual pulse output, strong 8000W power and an LCD voltage readout combine to deliver consistent results and straightforward operation. Durable construction and clear charging guidance make it a sensible long-term tool for occasional and semi-regular use.
