3. Setup

3.1 Charging the Device

Before first use, fully charge the spot welder using the provided Type-C charging cable and a compatible USB power adapter (not included). The display will indicate charging status.

3.2 Preparing for Welding

• Clean Surfaces: Ensure the nickel strips and battery terminals are clean and free of oil, dirt, or oxidation. Use the included sandpaper to lightly abrade surfaces if necessary, then wipe with alcohol. Clean surfaces are crucial for strong welds.
• Adjust Welding Pins: The welding pins can be adjusted for spacing. Loosen the fixing screws on both sides, adjust the pins to the desired width for your application, and then tighten the screws securely.

4. Operating Instructions

4.1 Power On/Off

Press and hold the power button (labeled '1' in Image 3.1) for a few seconds to turn the device on or off.

4.2 Navigating the Display and Settings

The 1.5-inch digital display provides real-time information and allows for parameter adjustments. Use the adjustment buttons (labeled '2' and '3' in Image 3.1) to navigate menus and change values.

• Mode Selection: Toggle between Auto and Manual welding modes.
• Preheat Time: Adjust the preheat duration for optimal welding.
• Trigger Time: Set the pulse duration for the weld.
• Power Level: Select from 90 adjustable power levels (0.1 to 9.9) to match material thickness.
• Language: Change the display language.
• Sound: Enable or disable audible feedback.
• Display Brightness: Adjust screen illumination.
• Auto-Off Time: Set the duration after which the device automatically powers off due to inactivity.

4.3 Welding Procedure

1. Select Mode: Choose either Auto or Manual mode based on your preference and application.
2. Adjust Power: Set the power level according to the thickness of the nickel strip and the battery type. Start with a lower setting and increase gradually if welds are weak. The device supports welding nickel-plated sheets from 0.1mm to 0.2mm.
3. Position: Place the nickel strip firmly onto the battery terminal. Position the welding pins squarely on the nickel strip, ensuring both pins make good contact.
4. Weld:
   • Auto Mode: The device will automatically detect contact and trigger the weld pulse.
   • Manual Mode: Press the manual trigger button (located on the side) to initiate the weld pulse.
5. Inspect: After welding, gently test the strength of the weld. If it's weak, increase the power level and re-weld a new spot.

5. Maintenance

5.1 Cleaning Welding Pins

Regularly inspect the welding pins for any residue or oxidation. Clean them gently with fine sandpaper or a wire brush to ensure good electrical contact and consistent weld quality.

5.2 Replacing Welding Pins

If the welding pins become worn or damaged, they can be replaced:

1. Loosen the fixing screws of the welding pins on both sides using a screwdriver.
2. Remove the old soldering pins by pulling them out in the direction of the pin.
3. Install new soldering pins, ensuring they are fully seated.
4. Adjust the spacing of the new pins as needed.
5. Tighten the fixing screws securely on both sides.

5.3 Storage

Store the spot welder in a cool, dry place away from direct sunlight and moisture. Ensure the device is turned off before storage.

6. Troubleshooting

• Weak Welds:
  • Ensure battery terminals and nickel strips are clean.
  • Increase the power level setting.
  • Apply firm and even pressure to both welding pins.
  • Check if welding pins are worn and replace if necessary.
