1.1 Safety Information
Please read and understand all safety warnings and instructions before operating this device. Failure to follow these instructions may result in electric shock, fire, serious injury, or property damage. Keep this manual for future reference.
- Eye Protection: Always wear appropriate eye protection (welding goggles or shield) to protect against sparks and intense light.
- Ventilation: Operate in a well-ventilated area to avoid inhaling welding fumes.
- Electrical Safety: Do not operate the welder with wet hands or in damp conditions. Ensure all connections are secure.
- Flammable Materials: Keep flammable materials away from the welding area. Sparks can ignite nearby substances.
- Battery Safety: When welding batteries, ensure they are not overcharged or damaged. Improper handling of batteries can lead to explosion or fire.
- Children and Pets: Keep the device out of reach of children and pets.
- Maintenance: Disconnect power before performing any maintenance or cleaning.

3. Setup
Follow these steps to prepare your spot welder for operation.
3.1 Charging the Device
Before first use, fully charge the spot welder. Connect the provided Type-C charging cable to the charging port on the device and to a suitable USB power adapter (not included). The display will indicate charging status.
3.2 Connecting Welding Pens
Insert the two welding pens into the designated ports on the front of the spot welder. Ensure they are securely connected. The design allows for flexible positioning of the pens, either from the front or side, to suit your working style.

Figure 3: Welding Pen Connection Flexibility
Note: Using the front opening for the welding pens allows for greater flexibility and an effective usage length of approximately 40cm without winding. Side opening may require bending the wire and offers a shorter effective length.
3.3 Connecting the Foot Pedal (Optional)
If you prefer foot-pedal operation, connect the foot pedal board to its dedicated port on the spot welder. This allows for hands-free triggering of the weld.
4. Operating Instructions
This section details how to operate your Awithz UK1 spot welder.
4.1 Powering On/Off
Press and hold the power button to turn the device on or off. The digital display will illuminate upon power-on.
4.2 Understanding the Display and Controls
The Awithz UK1 features a digital display and a control knob for adjusting settings.

Figure 4: Control Panel and Display
- Mode: Selects between Automatic (A) and Manual (M) welding modes.
- Gear: Adjusts the welding power level from 1 to 100. Higher numbers indicate more power.
- Trigger: Sets the trigger time (pulse duration) from 1 to 20ms.
- Cont Welds: Configures continuous welds (1 or 2 times).
- Knob: Used to navigate through settings and adjust values.
4.3 Selecting Welding Modes
The device supports three welding modes:
- Manual Mode: The weld is triggered by pressing a button on the welding pen or the foot pedal.
- Automatic Mode: The weld is triggered automatically when both welding pen tips make contact with the workpiece.
- Foot Pedal Mode: The weld is triggered by pressing the connected foot pedal.
Use the control knob to select your desired mode on the display.
4.4 Adjusting Welding Parameters
Rotate the control knob to navigate between 'Mode', 'Gear', 'Trigger', and 'Cont Welds'. Press the knob to select a parameter, then rotate to adjust its value. Press again to confirm the setting.
- Gear (Power): Start with a lower gear setting (e.g., 20-30) and gradually increase until a strong weld is achieved. The optimal setting depends on the material thickness and type.
- Trigger (Pulse Duration): Adjusts how long the welding current flows. Shorter durations for thinner materials, longer for thicker.
- Cont Welds (Pulse Count): For stronger welds, you can set the machine to deliver 2 pulses per trigger.
4.5 Welding Process
Ensure the workpiece (e.g., nickel strip and battery terminal) is clean and free of oxidation. Use the included sandpaper if necessary.
- Place the nickel strip firmly against the battery terminal.
- Position the two welding pen tips onto the nickel strip, ensuring they are parallel and make good contact with the material. Apply slight pressure.
- Trigger the weld according to your selected mode (manual button, foot pedal, or automatic contact).
- Observe the weld. A good weld will be strong and clean. Adjust settings (Gear, Trigger, Cont Welds) as needed for optimal results.

Figure 5: Welding Capability and Dual Pulse Energy
The Awithz UK1 utilizes a 9000W high-power dual pulse energy system for strong and reliable welds. It can weld various materials up to specific thicknesses:
- Copper sheet: 0.1mm (MAX)
- Steel sheet: 0.25mm (MAX)
- Iron sheet: 0.25mm (MAX)
- Nickel plated sheet: 0.3mm (MAX)
- Pure nickel sheet: 0.15mm (MAX)
5. Maintenance
Proper maintenance ensures the longevity and performance of your spot welder.
- Cleaning: Regularly clean the welding pen tips and the main unit with a dry, soft cloth. Ensure no metal dust or debris accumulates around the welding area.
- Replacing Welding Pins: If the welding pins become worn or damaged, replace them with the provided spare pins or genuine replacements. Ensure the new pins are securely installed.
- Storage: Store the spot welder in a cool, dry place away from direct sunlight and moisture. Disconnect all cables before storage.
- Battery Care: For optimal battery life, avoid fully discharging the unit frequently. Charge it regularly, even during periods of non-use.
6. Troubleshooting
If you encounter issues with your spot welder, refer to the following common problems and solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| No weld or weak weld | Low power setting (Gear) Short trigger time Poor contact with workpiece Worn welding pins Dirty workpiece/nickel strip | Increase 'Gear' setting Increase 'Trigger' time Ensure firm contact with both pens Replace welding pins Clean materials with sandpaper |
| Unit does not power on | Battery discharged Faulty power button | Charge the unit fully Contact customer support |
| Overheating | Continuous heavy use Poor ventilation | Allow the unit to cool down Ensure adequate airflow around the device |
| Foot pedal not working | Not connected properly Incorrect mode selected | Check foot pedal connection Ensure 'Foot Pedal Mode' is active |
