5. Setup

5.1 Charging the Device

Before first use, fully charge the spot welder using the provided Type-C charging cable and a 5V/2.1A (MAX) power adapter. The digital display will indicate the battery level.

5.2 Power On/Off

Press and hold the ON/OFF/Option Toggle Key (top button) for 2 seconds to power the device on or off.

5.3 Adjusting Welding Pins

The Awgem spot welder features scientifically replaceable soldering pins with adjustable spacing (0.5-3mm) to adapt to diverse welding needs.

1. Loosen the fixing screws on both sides of the welding pins.
2. Remove the soldering pin by pulling it in the direction of the pin.
3. Insert new soldering pins and adjust the desired spacing.
4. Tighten the fixing screws on both sides to secure the pins.

Note: To disassemble and replace the needle, please use a 3mm outer diameter cross screwdriver with a welding needle screw for embedded fixation. Do not forcibly remove screws if they are not loosening, as this may cause damage to the shell.

6. Operation

The spot welder features a 1.3-inch intelligent digital display for precise control and monitoring of welding parameters.

6.1 Adjusting Welding Parameters (Gear Adjustment)

The device offers adjustable output power (gears) to suit different welding materials and thicknesses.

• SH2 Model: 90 adjustable gears.
• SH1 Model: 11 adjustable gears.

To adjust parameters:

1. Short press the Adjustment Key (top button) to cycle through and adjust parameters (e.g., gear level).
2. Press and hold the Adjustment Key to toggle between integer and decimal values for gear adjustment.

6.2 Switching Welding Modes

The spot welder supports both automatic and manual welding modes.

To switch modes:

• Press and hold the Manual Welding Key (bottom button) for 2 seconds to switch between automatic (A) and manual (M) welding modes.

6.3 Welding Process

The device utilizes dual pulse technology for firm solder joints without virtual welding.

1. Ensure the battery surface and nickel strip are clean and free of oxidation. Use the provided sanding paper if necessary.
2. Place the nickel strip firmly on the battery terminal.
3. Position the welding pins onto the nickel strip, ensuring both pins make good contact.
4. In Automatic Mode, the welder will automatically detect contact and initiate the weld.
5. In Manual Mode, press the Manual Welding Key to initiate the weld.
6. After welding, carefully remove the welder. Inspect the weld for strength and quality. Adjust the gear setting if the weld is too weak or too strong.

Weldable Materials and Thicknesses:

• Nickel Plating: Up to 0.25mm (MAX)
• Steel Sheet: Up to 0.2mm (MAX)
• Iron Sheet: Up to 0.2mm (MAX)
• Pure Nickel Sheet: Up to 0.15mm (MAX)

6.4 Applications

The Awgem spot welder is widely applicable for:

• Cylindrical Cell Welding (e.g., 18650, 26650, 36650 lithium batteries)
• Cell Phone Battery Transplantation
• Sheet Metal Welding
• Button Cell Welding
• Electronic and electrical equipment maintenance
• Battery pack production and assembly
• Assembly of various types of mobile phone battery cells/digital electronic product batteries

7. Maintenance

• Cleaning: Regularly clean the welding pins and the device body with a dry, soft cloth. Ensure no debris or metal particles accumulate around the pins.
• Pin Condition: Inspect welding pins for wear or damage. Replace them if they become dull or corroded to ensure optimal welding performance.
• Storage: Store the device in a cool, dry place away from direct sunlight and moisture. Ensure the battery is partially charged (around 50%) for long-term storage.
• Charging: Charge the device when the battery indicator is low. Avoid completely draining the battery frequently to prolong its lifespan.

8. Troubleshooting

If you encounter issues with your spot welder, consider the following:

• Poor Welds:
  - Insufficient Power: Increase the gear setting. Ensure the battery is fully charged.
  - Poor Contact: Ensure welding pins are clean and make firm, even contact with the nickel strip and battery. Adjust pin spacing if necessary.
  - Material Compatibility: Verify that the material and thickness are within the device's welding capabilities (e.g., max 0.25mm for nickel plated).
• Device Not Powering On:
  - Ensure the battery is charged. Connect to a charger and try again.
  - Press and hold the ON/OFF/Option Toggle Key for 2 seconds.
• Automatic Shutdown: The device is designed to shut down after 6-8 minutes of inactivity. This is normal behavior. Power it on again if needed.
• Display Issues: If the digital display is not functioning correctly, try restarting the device. If the issue persists, contact customer support.

9. User Tips

• Practice First: Before welding on critical components, practice on scrap nickel strips and old batteries to find the optimal gear setting for your specific materials.
• Clean Surfaces: Always ensure the surfaces to be welded are clean and free of dirt, grease, or oxidation for the best weld quality. Use the provided sanding paper for preparation.
• Consistent Pressure: Apply consistent and firm pressure on the welding pins to ensure good electrical contact during the weld.
• Monitor Display: Pay attention to the digital display for battery level, gear setting, and temperature to ensure optimal performance and prevent issues.
• Adjust Pin Spacing: Utilize the adjustable pin spacing feature to match the size of your welding material and achieve precise welds.
