- The LED panel will display the charging voltage. Allow the unit to charge until the charging voltage stabilizes, indicating the capacitors are fully charged and ready for operation.
5. Instruccions de funcionament
5.1 Understanding the LED Panel Display

The intelligent LED panel provides real-time feedback on key welding parameters:
- Vol. De càrregatage (DCV): Mostra el volum actualtage of the capacitors.
- Actual Welding Current (KA SW): Shows the actual current delivered during a weld.
- Energy Grade (mS AT/MT): Indicates the set welding energy level (1-99t) and the selected welding mode (AT for Automatic, MT for Manual/Pedal).
5.2 Ajust dels paràmetres de soldadura
- Use the 'UP' and 'DOWN' buttons on the control panel to adjust the welding energy grade (1-99t).
- The optimal energy grade depends on the material thickness and type. Start with a lower setting and gradually increase until satisfactory welds are achieved.
5.3 Selecting Welding Modes

The VEVOR 801D supports two welding modes:
- Automatic (AT) Mode: Ideal for fast and efficient welding of large quantities. The welder automatically detects contact with the workpiece and initiates the weld.
- Pedal-Controlled (MT) Mode: Provides precise control over the welding process. The weld is initiated by pressing the foot pedal switch. This mode is suitable for fine-tuning and intricate tasks.
Switch between modes using the PWR/SET button or as indicated on the display.
5.4 Procés de soldadura


- Prepare the workpieces: Ensure the surfaces to be welded are clean, dry, and free of oxidation.
- Place the nickel strip (or other material) onto the battery terminal or workpiece.
- Position the welding pen needles firmly onto the nickel strip, ensuring good contact with both the strip and the underlying material.
- For AT Mode: The weld will automatically trigger once proper contact and pressure are detected.
- For MT Mode: Press the foot pedal to initiate the weld.
- After the weld, lift the welding pen. Inspect the weld for strength and appearance. Adjust energy settings as needed.
5.5 Aplicacions


The VEVOR 801D is suitable for:
- Spot welding pure nickel strips (0.1-0.3mm)
- Assembling various battery packs (e.g., large lithium iron phosphate, polymer, 32650, power tool batteries)
- Welding small hardware components
- Connecting electronic components
6. Manteniment
6.1 Neteja
- Regularly clean the welding pen needles and the contact points on the main unit to ensure optimal conductivity.
- Use a soft, dry cloth to wipe down the exterior of the unit. Do not use abrasive cleaners or solvents.
6.2 Substitució d'elèctrodes
- Over time, the welding pen needles will wear down. Replace them when they become blunt or pitted to maintain welding quality.
- Refer to Figure 5 for guidance on replacing the welding electrodes. Ensure the new electrodes are securely installed.
6.3 Emmagatzematge
- When not in use, store the spot welder in a cool, dry place, away from direct sunlight and moisture.
- Keep the unit and accessories in their original packaging or a protective case to prevent damage.
