2. Safety Information
Always observe the following safety precautions when operating the Awithz P120D spot welder:
- Ensure the power switch is OFF before connecting or disconnecting any components.
- Wear appropriate personal protective equipment (PPE), including welding gloves and eye protection, to prevent injury from sparks, heat, and electrical hazards.
- Do not touch the welding pens or workpieces immediately after welding, as they will be hot.
- Operate the machine in a well-ventilated area to avoid inhaling fumes.
- Keep the work area clean and free of flammable materials.
- Never attempt to weld materials beyond the machine's specified thickness limits.
- Do not place the welding pens in contact with each other or with conductive objects when the machine is powered on.
- Regularly inspect the power cord, welding pens, and connections for damage.

5. Operating Instructions
- Power On: Flip the power switch on the rear panel to the ON position. The LCD display will illuminate.
- LCD Display and Controls: The LCD display shows various welding parameters. Use the adjustment keys (located below the display) to navigate and modify settings. The video below provides a visual guide to the controls.
- Adjusting Welding Parameters: The P120D offers ten thousand precise adjustments based on six core elements:
- Welding Method: Manual/Automatic
- Preheat: 0~5ms
- Intermittence: 1~20ms
- Gear Position: 000~999 (999 level fine tuning)
- Trigger Time: 0.5~5.0s
- Connect the dots: 1-3 times

Select the appropriate settings based on the material and thickness you are welding. Refer to the specifications section for maximum welding thicknesses for different materials.
- Welding Process:
- Place the material to be welded on a stable, non-conductive surface.
- Position the welding pen tips firmly against the material at the desired welding point.
- Press the foot pedal to initiate the weld. The machine will apply the set parameters.
- Release the foot pedal once the weld is complete.

- Power Off: Once welding is complete, turn the power switch to the OFF position and unplug the machine from the power outlet.
6. Maintenance
- Welding Pen Maintenance: The welding pens feature replaceable soldering pins. Regularly inspect the pins for wear and tear. Replace them when necessary to ensure optimal welding performance. Use the included file to clean and sharpen the welding needle tips as needed.
- Cleaning: Keep the main unit and welding pens clean and free of dust and debris. Use a dry cloth to wipe down the surfaces. Do not use abrasive cleaners or solvents.
- Heat Dissipation: The P120D is designed with efficient heat dissipation for continuous operation. Ensure the ventilation grilles are not obstructed during use.
- Storage: Store the machine and accessories in a dry, clean environment away from direct sunlight and extreme temperatures.

7. Troubleshooting
- No Power: Check the AC power cord connection and ensure the power switch is ON. Verify the power outlet is functional.
- Weak Welds: Adjust the 'Gear Position' or 'Trigger Time' settings. Ensure the welding pen tips are clean and sharp. Verify the material thickness is within the machine's capabilities.
- Overheating: If the machine feels excessively hot, allow it to cool down. Ensure ventilation grilles are clear. Reduce the intensity or duration of welding tasks.
- Inconsistent Welds: Ensure firm and consistent pressure is applied to the welding pens. Check for proper contact between the welding tips and the workpiece.

9. User Tips
- For optimal results, always perform test welds on scrap material before working on your final project.
- Experiment with different 'Gear Position' and 'Trigger Time' settings to find the perfect combination for your specific material and thickness.
- Ensure the welding pen tips are always clean and sharp for consistent and strong welds.
- When welding batteries, ensure they are properly secured in a fixture (like the included 18650 fixture) to prevent movement during the welding process.
