4. Setup and Initial Use
4.1. Charging the Device
Before first use, fully charge the Awgem AS2 using the provided Type-C charging cable. Connect the cable to the Type-C charging port on the device and a suitable USB power adapter (not included). The LCD display will indicate charging status.
4.2. Power On/Off
To power on the device, long-press the ON/OFF/Gear Switching Key located on the side of the unit. Long-press again to power off.
4.3. Adjusting Welding Pins
The welding pins are interchangeable and their spacing can be adjusted to suit different welding requirements. Use a small screwdriver to loosen the screws, adjust the pin spacing, and then tighten the screws securely.

5. Operating Instructions
5.1. Mode Selection (Automatic/Manual)
The Awgem AS2 supports both Automatic and Manual welding modes. To switch between modes, press and hold the main button (Welding Trigger). The LCD display will show 'A' for Automatic mode or 'M' for Manual mode.
- Automatic Mode: The welder will automatically detect contact with the nickel strip and trigger the weld.
- Manual Mode: A short press of the main button (Welding Trigger) is required to initiate a weld after positioning the pins.
5.2. Gear Adjustment (Welding Power)
The device offers 99 adjustable gears (power levels) to accommodate different material thicknesses (0.1mm to 0.2mm nickel sheet) and desired weld strength. Short press the Adjustment Key (located near the Type-C port) to cycle through the gear settings. Press and hold the Adjustment Key to switch between parameter options (e.g., preheat time, delay).

5.3. Welding Process
- Prepare the Surface: Ensure the nickel strip and battery terminals are clean and free of rust or oxidation. Use the included frosted paper (sandpaper) if necessary.
- Position the Nickel Strip: Place the nickel strip firmly on the battery terminal.
- Position the Welder: Hold the Awgem AS2 at a 45°-60° angle, ensuring both copper needles firmly touch the nickel strip and the underlying battery terminal.
- Initiate Weld:
- In Automatic Mode, the weld will trigger automatically upon firm contact.
- In Manual Mode, short press the main button (Welding Trigger) to initiate the weld.
- Inspect the Weld: Check the weld joint for strength and appearance. Adjust the gear setting if the weld is too weak or too strong.

5.4. Welding Tips
- Practice on a large area of iron or stainless steel before welding batteries to ensure smooth operation.
- Clean the nickel strip flat and avoid overhang, as this can cause holes in the strip or damage the battery.
- The welding pins may oxidize after repeated use. Polish them with the included sandpaper before welding to maintain optimal performance.
- During and after welding, the soldering pin, nickel strip, and battery will generate heat. Do not touch them immediately to avoid burns.

6. Maintenance
6.1. Cleaning
Regularly clean the welding pins and the device housing to prevent accumulation of debris and ensure optimal performance. Use a soft, dry cloth. Do not use abrasive cleaners or solvents.
6.2. Welding Pin Replacement
The copper welding needles are consumable parts and may wear down over time. Replace them when they become significantly worn or damaged to maintain welding quality. Use the provided spare needles and ensure they are securely fastened.
7. Troubleshooting
- Weak or No Weld:
- Ensure the battery is fully charged.
- Increase the welding gear (power level).
- Clean the welding pins and the nickel strip/battery terminals.
- Ensure both pins make firm, simultaneous contact with the workpiece.
- Verify the material thickness is within the 0.1mm-0.2mm range for nickel sheets.
- Excessive Sparking or Burn-through:
- Decrease the welding gear (power level).
- Ensure proper contact pressure; too much pressure can sometimes cause issues.
- Device Not Powering On:
- Ensure the battery is charged.
- Perform a long-press on the power button.
