4. Setup

4.1 Wire Installation (MIG/Flux Core)

To install the welding wire for MIG or Flux Core welding:

1. Open the side panel of the welder.
2. Place the wire spool onto the spindle and secure it.
3. Feed the wire through the wire feeder mechanism, ensuring it passes through the correct groove for the wire diameter.
4. Close the wire feeder tension arm and adjust the tension appropriately.
5. Thread the wire through the MIG torch liner until it emerges from the contact tip.

4.2 Connecting Welding Cables (MMA/Stick, Lift TIG)

For MMA (Stick) or Lift TIG welding, connect the electrode holder and ground clamp to the appropriate terminals on the front panel of the welder. Ensure connections are secure.

4.3 Gas Connection (Gas MIG)

For Gas MIG welding, connect the gas hose from your shielding gas cylinder (e.g., CO2 or Argon/CO2 mix) to the gas inlet on the back of the welder. Ensure all connections are tight and leak-free. Adjust the gas flow rate using the regulator on your cylinder.

4.4 Power Connection

The ANDELI MIG-145 AIR supports dual voltage (110V/220V). Use the appropriate power cord and adapter for your power supply. Ensure the power source matches the welder's requirements.

5.1 Mode Selection

Use the control panel to select your desired welding mode: Gas MIG, Flux MIG, Lift TIG, or MMA. The LED display will show the selected mode and relevant parameters.

5.2 Synergic Control Technology

In Synergic Control mode, simply adjust the amperage or welding wire diameter, and the system will automatically optimize voltage and wire feed speed for optimal results. This feature simplifies setup and ensures precision.

5.3 2T/4T Settings

The welder offers 2T (Two-Touch) and 4T (Four-Touch) trigger settings:

• 2T (Two-Touch): Press and hold the trigger to weld; release to stop. Ideal for short welds and precise control.
• 4T (Four-Touch): Press the trigger once to start welding, release, and the arc will maintain. Press again to stop. Perfect for long welds without hand fatigue.

7. Maintenance

Regular maintenance ensures the longevity and optimal performance of your ANDELI MIG-145 AIR welder.

• Cleaning: Periodically clean the welder's exterior and ventilation openings to prevent dust and debris buildup. Use compressed air to clear internal components if necessary, ensuring the machine is unplugged.
• Cable Inspection: Regularly inspect all welding cables, torch, and ground clamp for damage, fraying, or loose connections. Replace any damaged components immediately.
• Contact Tip & Nozzle: For MIG welding, frequently check and clean the contact tip and nozzle. Replace the contact tip when it becomes worn or clogged to ensure consistent wire feeding and arc stability.
• Wire Feeder: Keep the wire feeder rollers clean and ensure proper tension. Check for any obstructions in the wire liner.
• Storage: Store the welder in a clean, dry environment away from excessive dust, moisture, and extreme temperatures.

8. Troubleshooting

If you encounter issues with your welder, refer to the following common troubleshooting steps:

• No Power: Check the power cord connection, wall outlet, and circuit breaker. Ensure the welder's power switch is ON.
• No Arc: Verify that the ground clamp is securely attached to the workpiece and that the electrode/torch is making proper contact. Check for correct mode selection and parameter settings.
• Poor Weld Quality: Adjust voltage, amperage, and wire feed speed according to the material thickness and welding process. Ensure the workpiece is clean and free of rust or paint. Check for proper gas flow (for Gas MIG) or correct wire type (for Flux Core).
• Wire Feeding Issues: Check wire spool installation, wire feeder tension, and ensure the contact tip is not clogged. Inspect the wire liner for kinks or blockages.
• Overheat Protection: If the welder stops and displays an overheat warning, allow it to cool down. Ensure adequate ventilation around the machine.

For persistent issues, contact ANDELI customer support or a qualified technician.
