5. Setup

5.1 Initial Charging

Before first use, fully charge the spot welder. Connect the provided USB-C charging cable to the Type-C charging port on the device and to a suitable USB power adapter (not included).

• The display will indicate charging status. A full circle on the display indicates 100% charge.
• It is recommended to charge the device regularly, even during periods of inactivity, to maintain battery health.

5.2 Connecting Welding Pens

Insert the two spot welding pens into the designated installation interfaces on the front of the unit. Ensure they are securely connected.

5.3 Connecting Foot Pedal (Optional)

If using the foot pedal for manual welding, plug its connector into the Trigger Interface port on the unit.

6. Operating Instructions

6.1 Power On/Off

To power on or off the device, long press the adjustment knob.

6.2 Parameter Adjustment

The AWithZ UK1 offers precise control over welding parameters via its single knob interface. The display shows four main adjustable parameters: Mode, Gear, Trigger, and Cont Welds.

1. Rotate the knob to cycle through the available options (Mode, Gear, Trigger, Cont Welds).
2. Short press the knob to select the flashing option and enter adjustment mode for that parameter.
3. Rotate the knob to adjust the parameter value (clockwise to increase, counter-clockwise to decrease).
4. Short press the knob again to confirm the new setting and exit adjustment mode for that parameter.

Figure 4: Knob operation for parameter adjustment.

Parameter Details:

• Mode: Selects between Automatic (A) and Pedal (M) welding modes.
• Gear: Adjusts the welding power level from 1 to 100. Higher numbers indicate more power.
• Trigger: (Only for Automatic Mode) Sets the delay time (0.5-5 seconds) before a weld is triggered after the pens contact the material.
• Cont Welds: Sets the number of continuous welding pulses (1 or 2) for a single trigger.

6.3 Welding Process

The AWithZ UK1 is suitable for welding nickel-plated steel (0.1-0.35mm), pure nickel (0.1mm), and steel (0.1-0.3mm) for battery pack assembly and repair. It is commonly used for 18650 battery welding.

1. Prepare the Material: Ensure the nickel strip and battery terminals are clean and free of oxidation. Use the included sandpaper if necessary.
2. Position the Strip: Place the nickel strip firmly onto the battery terminal where the weld is desired.
3. Position Welding Pens: Hold the welding pens perpendicular to the nickel strip, with the tips making firm contact with the strip, directly above the battery terminal. Ensure the tips are close to each other but not touching.
4. Initiate Weld:
   • Automatic Mode: The weld will trigger automatically after the set delay once both pen tips make contact.
   • Pedal Mode: Press the foot pedal to trigger the weld. This offers more precise control over the timing.
5. Inspect Weld: After welding, gently test the strength of the weld. Adjust the 'Gear' (power level) as needed for stronger or weaker welds.

7. Maintenance

7.1 Electrode Tip Maintenance

Over time, the welding tips may oxidize or become worn, affecting weld quality. Use the provided sandpaper to gently polish the tips to remove any oxide layer. Replace the soldering pins if they become excessively worn or damaged.

7.2 Storage

Store the device in a cool, dry place when not in use. Detach the welding pens for easier storage and portability.

8. Troubleshooting

• Weak or Inconsistent Welds:
  • Ensure welding tips are clean and polished.
  • Increase the 'Gear' (power level) setting.
  • Verify the material thickness is within the specified range.
  • Ensure firm contact between welding pens, nickel strip, and battery terminal.
• Device Not Powering On:
  • Check battery charge level and recharge if necessary.
  • Ensure the power button (knob) is long-pressed correctly.
• Overheating: The device features intelligent thermal protection and auto-shutoff after 8 minutes of inactivity to prevent overheating. Allow the device to cool down if it becomes excessively warm.
