What is this Product AWithZ Spot Welder?
AWithZ Spot Welder Review
The AWithZ Spot Welder is a portable, rechargeable, handheld device designed specifically for spot welding nickel strips to batteries, most commonly 18650 lithium-ion cells. Unlike traditional soldering irons that use heat to melt solder, a spot welder uses a short, powerful electrical pulse to fuse two metal pieces together. This creates a strong, clean weld without overheating the battery, which is crucial for safety. This tool is primarily marketed towards the DIY community for building custom battery packs for e-bikes, power walls, and other electronics projects.
Real Use-Case (No Hype)
AWithZ Spot Welder Review
Let us be practical about where this handheld spot welder excels and where it falls short.
- ✅ DIY Battery Pack Building:
- This is its main purpose. It is great for hobbyists who want to build or repair small to medium-sized 18650 battery packs.
- ✅ Small Electronics Repairs:
- Useful for re-attaching battery tabs on small electronic devices where a traditional welder is too large.
- ✅ Learning Spot Welding:
- At a low price, it serves as an excellent entry-level tool for anyone who wants to learn the basics of battery spot welding.
- ✅ On-the-Go Repairs:
- Its portable and rechargeable nature makes it handy for quick repairs away from a dedicated workshop.
- ❌ Industrial or Heavy-Duty Use:
- It is not designed for continuous, high-volume production. The tips will overheat, and the battery will drain.
- ❌ Thick Nickel Strips:
- While it claims to weld up to 0.35mm, its performance is most reliable on 0.1mm to 0.2mm pure nickel strips. Thicker strips will require multiple pulses and may not create strong welds.
Key Features AWithZ Spot Welder
Here are the main specifications of the AWithZ Handheld Spot Welder:
- 1. ✅ 90 Gears of Adjustable Power: Allows for fine-tuning the pulse strength to match the thickness of the nickel strip.
- 2. ✅ Portable and Rechargeable: The compact, handheld design makes it easy to use anywhere, with a built-in rechargeable battery.
- 3. ✅ Interchangeable Soldering Pins: The copper welding pins can be replaced if they wear out, extending the life of the tool.
- 4. ✅ Strong Dual Pulse Output: Delivers two quick electrical pulses for a stronger, more reliable weld.
- 5. ✅ Weldable up to 0.35mm: Capable of welding thin nickel and nickel-plated steel strips.6. ✅ A-Grade Battery Cells: Uses high-quality internal battery cells for consistent power delivery.
- 7. ✅ Manual and Auto Modes: Offers both a manual trigger and an automatic mode that welds when both pins make contact.
Real Pros & Cons
AWithZ Spot Welder Review
Here is the honest breakdown of the AWithZ Spot Welder
| Pros (Advantages) | Cons (Disadvantages) |
| ✅ Extremely Affordable: It is one of the cheapest entry points into the world of DIY battery spot welding. | ❌ Inconsistent on Thicker Strips: The claim of welding 0.35mm is optimistic. It struggles with anything above 0.2mm, especially on pure nickel. |
| ✅ Very Portable: Its small size and rechargeable battery make it incredibly convenient compared to bulky, transformer-based welders | ❌ Overheating: During continuous use, the welding pins and internal components can get hot, requiring cooldown periods. |
| ✅ Easy to Use: The adjustable gears and simple interface are beginner-friendly | ❌ Battery Life: While rechargeable, the internal battery may not last for a very large battery pack project on a single charge. |
| ✅ Sufficient Power for Hobbyists: For typical DIY projects using 0.15mm nickel strips, it has more than enough power to create solid welds | ❌ Vague Instructions: The included user manual is often minimal and not very helpful for absolute beginners |

Helpful Buying Guide & FAQ
AWithZ Spot Welder Review
Here are the answers to common questions about this DIY battery spot welder
- Q: Can it weld pure nickel or just nickel-plated steel?
- A: It can weld both. However, it is much more effective on nickel-plated steel. For pure nickel, it is best to stick to 0.15mm thickness or below for strong, consistent welds
- Q: How do I know which gear to use?
- A: Start with a low gear setting on a scrap piece of nickel and a dead battery cell. Test the weld by trying to peel the nickel off. If it peels easily, increase the gear by 5-10 levels and try again. Keep increasing until the nickel tears when you try to pull it off, indicating a strong weld.
- Q: Is it safe to use on live batteries?
- A: Yes, that is its intended purpose. The electrical pulse is very short and localized, so it does not damage the battery cell. However, always follow proper battery safety protocols (like checking cell voltage and avoiding short circuits).
- Q: How do I charge it?
- A: It typically comes with a USB-C charging cable and can be charged using any standard USB phone adapter
Pro Tips for Better Welds
AWithZ Spot Welder Review
Getting a clean, strong weld with a handheld device requires some practice. Here are some tips to improve your results:
Clean Your Surfaces: Before welding, make sure both the battery terminal and the nickel strip are clean and free of any dirt or oils. Use a bit of isopropyl alcohol on a cloth to wipe them down.
Apply Firm Pressure: You need to apply consistent, firm downward pressure with both welding pins. If the connection is loose, the weld will be weak and might spark excessively.
Test on Scrap First: Never start welding on your main project. Always do a few test welds on a scrap piece of nickel and an old battery cell to find the perfect gear setting.
Pin Maintenance: The copper welding pins will oxidize and get dirty over time. Use a fine-grit sandpaper or a file to gently clean the tips to ensure a good electrical connection.
How to Use AWithZ Spot Welder (Step-by-Step Guide)
AWithZ Spot Welder Review
- 1. Charge: Before first use, fully charge the AWithZ spot welder using the provided USB cable.
- 2. Attach Pins: Make sure the copper welding pins are securely screwed into the device.
- 3. Prepare Your Materials: Get your 18650 battery cells and pre-cut nickel strips ready. Ensure the battery terminals and nickel strips are clean.
- 4. Power On & Select Gear: Press the power button to turn it on. Use the gear selection buttons to set your desired power level. Start low (around 30-40) for 0.15mm nickel.
- 5. Place Nickel Strip: Place the nickel strip flat across the battery terminal you want to weld.
- 6. Weld: Auto Mode: Firmly press both welding pins onto the nickel strip over the battery terminal. The device will automatically detect contact and fire the pulse. Manual Mode: Place the pins and press the manual fire button (if available) or use a foot-pedal attachment (if supported).
- 7. Test the Weld: After a couple of test welds, try to pull the nickel strip off. If the strip tears, leaving a piece behind, you have a strong weld. If the weld itself breaks, you need to increase the power (gear).
- 8. Repeat: Continue welding across all your battery terminals, allowing the welder to cool down if it gets too hot.
Final Verdict
AWithZ Spot Welder Review
- The AWithZ 90 Gears Adjustable Spot Welder is a fantastic tool for its target audience: the DIY hobbyist. It makes battery spot welding accessible and affordable for everyone. While it does not have the power of a professional machine and struggles with thicker nickel, its performance on standard 0.15mm strips is more than adequate for most DIY battery pack projects. Its portability and ease of use are major advantages. If you are an electronics enthusiast looking to build your own battery packs without breaking the bank, this handheld spot welder is an excellent value and a highly recommended starting point.
