4.1 Key Features

• 1.5-inch LCD Screen: Displays temperature, battery level, gear setting, trigger time, and continuous spot welding times.
• 99 Adjustable Gear Levels: Allows for precise control over welding strength, suitable for various material thicknesses (0.1mm to 0.25mm).
• Auto and Manual Modes: Provides flexibility for different welding scenarios.
• Integrated Spot Welding Pins: Designed for convenient one-handed operation.
• 7500mAh High Capacity Battery: Ensures extended usage and quick charging (approx. 3.5 hours).
• USB Power Bank Functionality: Can be used to charge other USB devices.

5. Setup

5.1 Initial Charging

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 LCD screen will indicate charging status. A full charge takes approximately 3.5 hours.

5.2 Preparing the Welding Surface

Ensure the surfaces to be welded are clean and free of oxidation, dirt, or grease. Use the provided frosted paper or fine-grit sandpaper to lightly abrade the nickel strip and battery terminals if necessary. Clean surfaces ensure optimal conductivity and strong welds.

6. Operating Instructions

6.1 Power On/Off

To power on the device, press and hold the ON/OFF/Option Toggle button located at the top of the unit. To power off, press and hold the same button. The device also features a low-power standby mode, activated by holding both adjustment buttons simultaneously.

6.2 Navigating the LCD Screen

The 1.5-inch LCD screen displays various parameters. Use the ON/OFF/Option Toggle button to select an option, and the two adjustment buttons (forward/backward) to change values within the selected option (e.g., gear level).

6.3 Adjusting Gear Levels

The device offers 99 adjustable gear levels (1.0 to 9.9) to accommodate different welding needs. Higher gear levels provide more welding power.

• Gears 1.0 - 3.9: Suitable for mobile phone batteries and very thin materials.
• Gears 4.0 - 7.0: Recommended for materials with thicknesses ranging from 0.1mm to 0.15mm.
• Gears 7.1 - 9.9: For materials with thicknesses ranging from 0.15mm to 0.25mm.

Note: Always perform test welds on scrap material to determine the optimal gear setting for your specific application and material thickness. Excessive power can damage the material or battery.

6.4 Welding Operation (Auto Mode)

In Auto Mode, the welding pulse is triggered automatically when both welding pins make proper contact with the material.

1. Place the nickel strip onto the battery terminal or desired welding point.
2. Position the integrated welding pins firmly and squarely onto the nickel strip, ensuring good contact with both the strip and the underlying material.
3. The device will automatically detect contact and initiate the welding pulse. You may hear a distinct "pop" sound.
4. Lift the welding pins. Inspect the weld for strength and quality.

6.5 Welding Operation (Manual Mode)

In Manual Mode, you control when the welding pulse is triggered.

1. Place the nickel strip onto the battery terminal or desired welding point.
2. Position the integrated welding pins firmly and squarely onto the nickel strip, ensuring good contact with both the strip and the underlying material.
3. Press the Manual Key (refer to Product Overview diagram) to initiate the welding pulse.
4. Lift the welding pins. Inspect the weld for strength and quality.

6.6 Continuous Spot Welding

The AWithZ H2 supports continuous spot welding, allowing for two consecutive welds to be performed quickly. This feature is useful for welding thicker materials or for creating stronger bonds. Consult the LCD screen for the continuous spot welding times indicator.

6.7 Power Bank Function

The device can also function as a power bank. Connect your USB device to the Type-C charging port on the spot welder using a compatible cable to charge it.

7. Maintenance

7.1 Cleaning the Welding Pins

Over time, the welding pins may accumulate residue or oxidize, affecting welding performance. Use the provided frosted paper or fine-grit sandpaper to gently clean the tips of the welding pins. Ensure the device is powered off before cleaning.

7.2 Storage

Store the spot welder in a cool, dry place, away from direct sunlight and moisture. Keep it in its original packaging or a protective case to prevent damage.

7.3 Battery Care

To prolong battery life, avoid fully discharging the battery frequently. Recharge the device when the battery level is low. If storing for an extended period, charge the battery to approximately 50% and recharge every 3-6 months.
