4. Setup

Before first use, ensure the device is fully charged and properly configured.

Charging the Device

1. Connect the provided USB charging cable to the welder's charging port.
2. Plug the other end of the USB cable into a compatible USB power adapter (not included) or a computer USB port.
3. The OLED display will indicate the charging status. Charge until the battery indicator shows full. A full charge typically takes approximately 2.5 hours.

Initial Power-On and Settings

1. Press and hold the ON/OFF/Option Toggle button to power on the device.
2. Upon first power-on, you may be prompted to select a language. Use the adjustment keys to navigate and confirm your selection.
3. Familiarize yourself with the OLED display. It shows current temperature, welding mode (Auto/Manual), preheat time, trigger time, and power level (Gear).
4. Use the adjustment keys to set desired parameters. The device offers 99 levels of power adjustment (Gear 1.0-9.9).

5. Operating Instructions

Follow these steps for effective and safe spot welding.

Preparation for Welding

• Ensure the surfaces to be welded (e.g., battery terminals, nickel strip) are clean and free of oxidation, dirt, or grease. Use sandpaper (included) to lightly abrade the nickel strip if necessary.
• Clean the welding tips with sandpaper to ensure good conductivity.
• Select the appropriate nickel strip thickness. The welder supports 0.1-0.15mm, and up to 0.2mm for pure nickel.

Setting Welding Parameters

The AWithZ H2 offers 99 adjustable power levels (Gear 1.0-9.9) and two welding modes: Automatic and Manual.

• Power Level (Gear): Adjust the power level using the adjustment keys. Start with a lower setting (e.g., 3.0-5.0) and perform test welds on the provided nickel sheet to find the optimal setting for your material. Higher numbers indicate higher power.
• Mode Selection:
  • Automatic Mode: The welder automatically detects contact with the welding surface and triggers the weld. This is generally recommended for ease of use.
  • Manual Mode: You must press the trigger button (located on the side of the device) for 1 second to initiate the weld after positioning the tips.
• Preheat Time (0-5ms): This setting controls a brief pre-pulse to help burn off surface impurities. Adjust as needed for cleaner welds.
• Trigger Time (0.5-5s): This setting determines the duration of the welding pulse.

Performing a Weld

1. Place the nickel strip firmly onto the battery terminal or desired welding point.
2. Position the two welding tips of the AWithZ H2 Spot Welder onto the nickel strip, ensuring both tips make firm and simultaneous contact with the strip and the underlying material. The optimal welding distance is 0.8mm between the tips.
3. In Automatic Mode: The weld will trigger automatically once proper contact is detected.
4. In Manual Mode: Press and hold the trigger button for 1 second to initiate the weld.
5. After the weld, lift the welder straight up. Inspect the weld for strength and appearance. A good weld will be strong and clean.
6. If the weld is too weak, increase the power level. If it burns through the nickel strip, decrease the power level.

6. Maintenance

Proper maintenance ensures the longevity and optimal performance of your spot welder.

• Cleaning Welding Tips: Regularly clean the welding tips with the provided sandpaper to remove any residue or oxidation. This ensures good electrical contact and consistent welds. Replace tips when they become excessively worn.
• Device Cleaning: Wipe the body of the welder with a soft, dry cloth. Do not use abrasive cleaners or solvents.
• Storage: Store the spot welder in a cool, dry place, away from direct sunlight and moisture. Ensure it is fully charged before long-term storage to preserve battery health.
