Introduction

This manual provides detailed instructions for the safe and effective use of your Portable 18650 Lithium Battery Spot Welder Kit. This device is designed for precise spot welding of nickel-plated steel plates and pure nickel steel plates, commonly used in battery pack assembly. It features a digital color display, 30 adjustable power gears, and can also function as a power bank.

Setup

1. Unboxing and Package Contents

Carefully unpack all items and ensure all components are present. Refer to the packing list below:

• 1 x Spot Welder Unit (Dimensions: 112x80x30mm)
• 2 x Welding Pens (with 30cm wire)
• 1 x USB Charging Cable
• 1 x Nickel Strip
• 1 x Usage Guide (this manual)
• 1 x Insulating Sticker

2. Initial Charging

The product should be fully charged before its first use to ensure optimal performance and battery longevity. Connect the device to a suitable USB power adapter using the provided USB charging cable via the 2.1A Type-C input port.

3. Connecting Welding Pens

Insert the two welding pens into the designated welding pen output interfaces on the device. Ensure they are securely connected.

Operating Instructions

1. Power On/Off

• To power on or off the device, long press the white button (On/Off switch).

2. Understanding the Digital Display

The 1.8-inch digital color display provides real-time information and allows for parameter adjustments. The main interface shows:

• Battery Status: Battery voltage and percentage.
• Temperature: Accurate internal casing temperature.
• Current: Built-in ammeter displays the current value of each spot welding pulse.
• PreH (Preheat): Preheat pulse setting.
• Gear: Main pulse setting (adjustable from 1 to 30).
• Gap: Interval between preheat and main pulse.
• Numb (Number of Pulses): Number of output pulses.
• Home/Set: Navigation to the home page or settings menu.

3. Adjusting Parameters

The device offers 30 adjustable power gears and multiple parameters for precise welding. You can adjust these parameters on the home screen to combine over a thousand different gear settings.

• Press the white button to switch to the next option on the display.
• Press the black button to change the value of the selected parameter.

4. Spot Welding Process

The spot welder supports welding of 0.1-0.25mm nickel-plated steel plates and 0.15mm pure nickel steel plates. For optimal results, ensure the device is fully charged.

1. Prepare the nickel strip and battery terminals.
2. Select the appropriate gear setting based on the material thickness and type.
3. Place the welding pens firmly on the nickel strip and battery terminal.
4. When the welding pen touches the nickel plate, the self-checking function is automatically triggered, and the response time is 0.8 seconds. The device will then execute the welding pulse according to your settings.

5. Screen Flip Function

• To rotate the screen display, press both the white and black buttons simultaneously. This allows you to adjust the screen orientation according to your working situation.

6. Power Bank Functionality

The device features a 5000mAh high-capacity lithium battery and a 2.4A USB output port, allowing it to function as a power bank to conveniently charge your phone or other devices.

Maintenance

1. Cleaning

• Ensure the device is powered off and disconnected from any power source before cleaning.
• Wipe the exterior with a soft, dry cloth. Avoid using abrasive cleaners or solvents.
• Keep the welding pen tips clean for optimal conductivity and welding performance.

2. Storage

• Store the spot welder in a cool, dry place away from direct sunlight and moisture.
• Ensure the battery is partially charged (around 50-70%) before long-term storage to maintain battery health.

3. Battery Care

• The 5000mAh lithium battery is designed for low power consumption and long use time. It features low current protection and can maintain standby for over a year.
• Avoid fully discharging the battery frequently.
• If the copper electrodes of the welding pens wear out, they may be replaceable. Consult the manufacturer or seller for information on obtaining replacement parts.

Troubleshooting

This section addresses common issues you might encounter with your spot welder.

1. Poor Welding Quality

• Issue: Welds are weak, inconsistent, or burn through the nickel strip.
• Solution: Adjust the 'Gear' (main pulse), 'PreH' (preheat pulse), and 'Gap' (interval) settings. Different materials and thicknesses require different parameters. Experiment with small adjustments until a strong, clean weld is achieved. Ensure the battery is fully charged, as low battery can affect welding power.

2. Device Not Powering On

• Issue: The device does not turn on after long-pressing the power button.
• Solution: Ensure the battery is charged. Connect the device to a power source using the USB-C cable and allow it to charge for at least 15-30 minutes before attempting to power it on again.

3. Overheating

• Issue: The device feels excessively hot during use.
• Solution: The device has built-in over-temperature protection. If it overheats, it may automatically shut down. Allow the device to cool down before resuming operation. Avoid continuous heavy use without breaks.

4. Display Issues

• Issue: Screen is frozen or unresponsive.
• Solution: Use the 'Reset hole' (refer to Figure 4) to perform a hard reset. A small pin or paperclip can be used to press the reset button.

Warranty and Support

For any questions, technical assistance, or warranty claims, please contact the seller or manufacturer directly. Keep your purchase receipt as proof of purchase.

User Tips

• Initial Charge: Always fully charge the device before its first use to ensure optimal battery performance and lifespan.
• Parameter Adjustment: For optimal welding results on nickel strips, experiment with the 30 adjustable gear settings (PreH, Gear, Gap, Numb) to find the precise parameters for your specific material thickness and type. Welding effect is better and more convenient when settings are tailored.
• Screen Orientation: Utilize the screen flip function (press both buttons simultaneously) to adjust the display orientation for better visibility in various working positions.
• Power Bank Function: Remember that your spot welder can double as a power bank to charge your mobile devices, offering added utility.
• Electrode Replacement: If the copper electrodes on your welding pens show signs of significant wear, they may need replacement. Check with the seller for availability of spare parts.
