1. Introduction
The QianLi Macaron 2S is a portable spot welding machine designed for precision tasks such as mobile phone battery flex soldering and other small-scale welding applications. It features a double pulse spot welding design for stable output and firm welds, and offers both automatic and manual operating modes. Its compact size and integrated welding pens make it a versatile tool for electronics repair.
2. Product Features
- Double Pulse Spot Welding: Ensures stable output and firm, reliable spot welds by utilizing a preheat pulse to clean the surface oxide layer and a main pulse for effective welding.
- Adjustable Output Power: 11 levels of adjustable output power for precise control over welding intensity.
- Automatic/Manual Modes: Easily switch between automatic mode (outputs immediately when welding pens touch metal) and manual mode.
- Integrated Welding Pen: Features an integrated design with red-copper welding terminals for enhanced conductivity, protected by a heat-insulation sleeve.
- Portable Design: Compact and lightweight, making it suitable for on-the-go repairs.
- Power Bank Functionality: Equipped with a USB 5V output port, allowing it to charge mobile devices.
- Type-C Charging: Convenient and fast charging via a Type-C input port.
3. Setup
- Charging the Device: Before first use, fully charge the Macaron 2S using a standard Type-C charger. The charging port is located on the side of the device.
- Connecting Welding Pens: Ensure the integrated welding pens are securely connected to the designated ports on the device. The red-copper terminals should be clean and free of debris.
- Preparing the Workpiece:
- Place the cell or workpiece on a stable, non-conductive surface.
- Adjust the welding base clamp (if applicable) to firmly hold the workpiece in place.
- Ensure the contact points on the workpiece are clean and free of oxidation for optimal welding results.
4. Operating Instructions
4.1 Power On/Off
- To power on the device, long-press the power button (usually marked with a power symbol).
- To power off, long-press the power button again.
4.2 Adjusting Output Power (Gear Levels)
- The Macaron 2S offers 11 levels of adjustable output power.
- Press the "Gear" button to cycle through the power levels (1-11).
- Indicator lights (blue, yellow, orange) will show the current gear level and mode.
4.3 Selecting Operating Mode (Automatic/Manual)
- The device supports both automatic and manual spot welding modes.
- Use the mode switch (labeled "Manual / Automatic") to select your desired mode.
- In Automatic Mode, the machine will output immediately when both welding pens detect contact with the metal workpiece.
- In Manual Mode, you will need to press the "Manual spot welding button" to initiate the weld after placing the pens.
4.4 Performing a Spot Weld
- Select the appropriate power level for your material.
- Position the welding pens firmly on the desired welding points of the workpiece.
- If in Automatic Mode, the weld will occur automatically upon contact. If in Manual Mode, press the manual spot welding button.
- The device utilizes a double pulse welding process:
- Step 1: Preheat pulse - Cleans the surface oxide layer to reduce spark splashing.
- Step 2: Main pulse - Improves welding success rate, resulting in a firm, stable, and reliable weld.
- Once the weld is complete, lift the welding pens from the workpiece.
4.5 Using as a Power Bank
- The Macaron 2S can also function as a portable power bank.
- Connect your mobile phone or other compatible device to the USB 5V output port using an appropriate charging cable.
- The device will begin charging your connected device.
5. Maintenance
- Cleaning: Regularly wipe the device and welding pens with a dry, soft cloth to remove dust and debris. Do not use abrasive cleaners or solvents.
- Welding Pens: The integrated welding pens feature red-copper terminals and a heat-insulation sleeve. Ensure the terminals remain clean and sharp for optimal performance. If they become dull or corroded, gently clean them.
- Storage: Store the device in a cool, dry place away from direct sunlight and moisture. Keep it out of reach of children.
- Battery Care: To prolong battery life, avoid fully discharging the device frequently. Charge it regularly, even if not in use for extended periods.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on | Low battery; Power button not pressed long enough. | Charge the device fully. Long-press the power button for 2-3 seconds. |
| Poor welding results (weak or no weld) | Incorrect power level; Dirty welding pens/workpiece; Insufficient pressure; Incorrect mode. | Increase power level. Clean welding pens and workpiece. Apply firm, consistent pressure. Ensure correct mode (Automatic/Manual) is selected. |
| Excessive sparking during welding | Surface oxidation on workpiece; Too high power level. | Ensure workpiece surface is clean. Reduce power level if necessary. |
| Device not charging external devices | Low battery; Incorrect cable; Device not in power bank mode (if applicable). | Charge the Macaron 2S. Use a compatible USB cable. Ensure the device is powered on. |

9. User Tips
- Practice Makes Perfect: If you are new to spot welding, practice on scrap materials first to get a feel for the different power levels and techniques.
- Cleanliness is Key: Always ensure both the welding pens and the workpiece contact points are clean and free of any contaminants (like oil, dirt, or heavy oxidation) for the best weld quality.
- Consistent Pressure: Apply consistent and firm pressure to both welding pens simultaneously when making a weld. Uneven pressure can lead to poor connections.
- Safety First: Always wear appropriate eye protection when operating the spot welder to protect against sparks.
