5. Operating Instructions
The Awithz P120D offers precise control over welding parameters via its adjustable LED screen. Familiarize yourself with the controls and settings before beginning any welding task.
5.1. Controls and Display:
- **LED Screen:** Displays current settings and status.
- **Power On/Off Button:** Located on the front panel.
- **Switch Key:** Used to navigate between settings on the display.
- **Adjustment Key:** Used to modify selected parameter values.
- **P- / P+ Terminals:** Connect the spot welding pens.
- **Trigger Interface:** Connect the foot pedal for activation.

5.2. Setting Welding Parameters:
Use the Switch and Adjustment keys to configure the following settings on the LED screen:
- **Welding Method:** Choose between Manual or Automatic.
- **Preheat:** Adjust preheating time from 0 to 5ms.
- **Intermittence:** Set the interval between welds from 1 to 20ms.
- **Gear Position:** Fine-tune power levels from 000 to 999.
- **Trigger Time:** Adjust the welding trigger duration from 0.5 to 5.0s.
- **Connect the Dots:** Set the number of weld pulses from 1 to 3 times.
5.3. Welding Procedure:
- **Prepare Materials:** Ensure the materials to be welded are clean, dry, and free from rust or contaminants.
- **Select Settings:** Based on the material type and thickness, adjust the welding parameters (Gear Position, Preheat, Intermittence, etc.) on the LED screen. Refer to the specifications section for material compatibility.
- **Position Workpiece:** Place the materials to be welded securely. For battery welding, use the 18650 fixture if applicable.
- **Perform Weld:**
- Hold the welding pens firmly, ensuring good contact with both materials at the desired weld point.
- Press the foot pedal to initiate the weld. The machine will execute the weld according to the set parameters.
- Release the foot pedal after the weld is complete.
- **Inspect Weld:** Visually inspect the weld for strength and quality. Adjust parameters as needed for optimal results.

6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your spot welder.
- **Welding Pen Care:**
- Inspect welding needles regularly for wear and tear.
- Replace worn-out welding needles promptly to maintain welding quality. The pens feature replaceable soldering pins for easy disassembly and replacement.
- Ensure the insulated tip wrapping is intact for safety and comfort.
- **Cleaning:**
- Keep the main unit and welding pens clean and free from dust, debris, and metal splatter.
- Use a dry, soft cloth for cleaning. Do not use abrasive cleaners or solvents.
- **Storage:** Store the spot welder in a dry, cool place, away from direct sunlight and moisture.


7. Troubleshooting
If you encounter issues with your Awithz P120D spot welder, refer to the following common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| Welder does not power on | No power supply, loose power cord, faulty power outlet. | Check power cord connection. Ensure power outlet is functional. Press the power button firmly. |
| Weak or inconsistent welds | Incorrect power settings (Gear Position), dirty or worn welding needles, poor contact with workpiece, material too thick. | Adjust Gear Position to a higher setting. Clean or replace welding needles. Ensure firm contact with materials. Verify material thickness is within welder's capacity. |
| Welder overheats | Continuous operation without sufficient cooling, blocked ventilation. | Allow the welder to cool down. Ensure ventilation ports are clear. Reduce welding frequency if operating in high temperatures. |
| Foot pedal unresponsive | Loose connection, faulty foot pedal. | Check the foot pedal connection to the "Trigger Interface". If problem persists, contact support. |
If the problem persists after trying these steps, please contact Awithz customer support for further assistance.
