AWithZ U3 5000mAh Portable Spot Welder Home Spot Welding Machine with USB Output and 80 Gears

Features:
Compact & Portable Spot Welder
* Dual-pulse is just the foundation—it's the thousands of fine-tuned modes that truly make the difference.
* After extensive research on the characteristics of various welding materials through tens of thousands of tests, we've identified six core factors and combined them to create a vast range of fine-tuned output modes—ensuring optimal welding performance for every scenario.

Grade A Battery Cells
* AWithZ uses only grade A battery cells, rejecting cheap, low-quality grade B/C cells with high self-discharge and safety risks. We exclusively use premium, high-rate grade A cells—ensuring safety, durability, and no power leakage.

Smart Handheld Welding Pen for Precise Triggering
* On top of automatic welding, AWithZ introduces a smart handheld welding pen, allowing you to precisely control trigger timing for more detailed and accurate spot welding.
* Detachable Alumina-Copper Welding Pins: Only high-purity alumina-copper alloy for durability & safety.
* Manual Welding Button: Enables you control the trigger timing with precision.
* Thick Copper Pen Wire: Features low resistance and low energy loss, and stays cool during use. Total length is 40cm.
* Comfortable to Use

5000mAh Powerful Output – Capable of Welding Copper Sheets
* Capable of welding copper sheets, pure nickel sheets, nickel-plated sheets and steel sheets.
* Maximum Welding Thickness: 0.25mm (for 5000mAh version).

Thousands of Fine-Tuned Modes for Precision Spot Welding
* Through extensive research on welding material characteristics, we've identified six key factors and developed thousands of fine-tuned output modes tailored for different materials and thicknesses.
* Equipped with a smart handheld welding pen, it delivers stronger, more precise welds.
* Preheat Time: 1–10ms
* Welding Modes: Manual / Automatic
* Continuous Welds: 1–3
* Interval Time: 1–20ms
* Power Levels: 1.0–9.0 (80 fine-tuned levels)
* Trigger Time: 0.5–5.0s

High-Quality 320×240 HD Color Screen
* With a premium 2.0-inch 320×240 true color HD screen, it delivers an exceptional user experience.

Exclusive, Smooth, User-Friendly Interface
* Custom-designed for intuitive, seamless operation—making welding control easier and more efficient.

30% Increase in Effective Working Length
* If the welding pen is too long, it causes excessive power loss and affects welding performance. If it's too short, it hinders operation. Tests show that 40cm is the optimal balance between efficiency and usability.
* With the same pen design, a front-opening port provides a longer effective length compared to a top-opening port. This model adopts a front-opening design, offering greater flexibility and an effective working length of approximately 40cm.

Safe Structural Design
* Engineered with a more scientific and reasonable layout: The circuit board and battery are not stacked, effectively preventing heat from the board from affecting battery safety and lifespan—greatly extending the overall durability of the device.

Multiple Safety Protections
* Equipped with a high-quality safety chip, temperature sensors, and intelligent safety algorithms, this device ensures secure operation through both software and hardware protection.

Additional Features
* Premium battery cells
* Impact protection
* Voltage regulation protection
* Short-circuit protection
* Low-temperature protection
* High-temperature protection
* Overcharge protection
* Over-discharge protection

USB Output
* It serves as both a spot welder and a power bank.
* With the USB output, it can be used to charge and power devices such as mobile phones and other USB-powered equipment.
