5. Setup
5.1 Charging the Device
Before initial use, fully charge the spot welder. Connect the provided Type-C charging cable to the device and a 5V/2.1A (MAX) power adapter. The display will indicate charging status. Avoid using chargers with higher voltage.
5.2 Welding Needle Installation and Adjustment
The Awgem spot welder features scientific interchangeable welding needles with adjustable spacing. This design allows for precise alignment and adapts to diverse welding needs.
- Loosen Screws: Loosen the fixing screws of the welding pins on both sides of the device.
- Remove Pin: Gently remove the existing soldering pin along its direction.
- Install New Pins: Install the new soldering pins.
- Adjust Spacing: Adjust the spacing between the pins to suit your welding requirements. The device supports welding distance adjustment.
- Tighten Screws: Tighten the fixing screws on both sides to secure the pins.
Note: Please use a 0.118inch/3mm outer diameter cross screwdriver for disassembly and replacement. The welding pin is embedded and does not need to be removed separately. Forcefully removing the screw may cause damage to the housing.
6. Operation
The Awgem spot welder features a 1.3-inch high-definition display screen that is intelligent, precise, intuitive, and user-friendly. It integrates preheating, intermittent welding, power regulation, and intelligent temperature control.
6.1 Power On/Off
Press and hold the power button to turn the device on or off. The display screen will light up upon activation.
6.2 Mode Selection (Automatic/Manual)
The spot welder supports both automatic and manual welding modes. Switch between modes using the designated button or interface on the device. The display will indicate the active mode.
6.3 Gear Adjustment
Adjust the output power (gear) according to the material thickness and type you are welding. The AS2 model offers 90 adjustable gears for fine precision, while the AS1 model provides 11 adjustable gears.
- AS2 Model: Features 90 levels of precision adjustment. Refer to the display for the current gear setting.
- AS1 Model: Features 11 levels of output power adjustment. For gears 1-6, adjust power clockwise (Inner Ring). For gears 7-11, adjust power counter-clockwise (Outer Ring).
6.4 Welding Process
Ensure the nickel strip and battery surfaces are clean and free of oxidation. Use the provided sandpaper if necessary. Place the nickel strip firmly against the battery terminal. Position the welding pins onto the nickel strip, applying even pressure. The device will automatically trigger a weld in automatic mode, or you can press the manual trigger button in manual mode.
7. Maintenance
7.1 Cleaning
- Regularly inspect and clean the welding pins. Use the provided sandpaper to remove any residue or oxidation that may accumulate on the tips. Clean pins ensure optimal welding performance.
- Wipe the device's body with a soft, dry cloth. Do not use abrasive cleaners or solvents.
7.2 Storage
- Store the spot welder in a cool, dry place, away from direct sunlight and moisture.
- Ensure the device is powered off before storing.
- For long-term storage, it is recommended to charge the battery to about 50-70% to prolong its lifespan.
7.3 Battery Care
- The device uses a high-quality polymer battery. Charge it regularly, even if not in frequent use, to maintain battery health.
- Avoid completely draining the battery or overcharging it for extended periods.
- The device has low power consumption and an automatic shutdown feature after 8 minutes of inactivity to conserve battery life.
8. Troubleshooting
This section addresses common issues you might encounter with your Awgem spot welder.
- Device not turning on: Ensure the battery is charged. Connect to a Type-C charger and check if the charging indicator lights up.
- Weak or inconsistent welds:
- Check battery charge level. Low battery can affect weld strength.
- Clean the welding pins with sandpaper to remove oxidation or residue.
- Adjust the gear setting to a higher level for stronger welds, especially for thicker materials.
- Ensure firm and even pressure is applied to the welding pins on the nickel strip.
- Verify that the nickel strip and battery terminals are clean.
- Device overheating: The device has built-in temperature protection. If it overheats, it will automatically trigger protection and may shut down. Allow it to cool down before resuming use. Ensure proper ventilation during operation.
- No welding spark:
- Check if the device is in the correct welding mode (manual or automatic).
- Ensure the welding pins are making good contact with the nickel strip and battery.
- Verify that the gear setting is not too low for the material.
- Short circuit protection activated: If a short circuit is detected, the device will activate protection. Power off the device, inspect the welding area for any conductive debris or improper contact, and resolve the issue before restarting.
9. User Tips
- Practice First: If you are new to spot welding, practice on scrap nickel strips and old batteries to get a feel for the device and find the optimal gear settings for different materials.
- Surface Preparation: Always ensure the surfaces to be welded (battery terminals and nickel strip) are clean and free of any dirt, grease, or oxidation. This significantly improves weld quality.
- Consistent Pressure: Apply consistent and firm pressure on the welding pins during the welding process. Uneven pressure can lead to weak or incomplete welds.
- Ventilation: Work in a well-ventilated area to dissipate any fumes produced during welding.
- Battery Pack Assembly: When assembling battery packs, plan your layout carefully and use appropriate battery holders or insulation to prevent accidental short circuits.
