Ensure the connections are secure. The earth clamp should be firmly attached to the workpiece (base metal) to ensure a good electrical circuit.
- Electrode Installation: Insert the appropriate electrode (1.6-3.2mm diameter) into the electrode holder.
- Power Connection: Connect the machine's power cord to a suitable 1~220-240V, 50/60Hz power outlet. Ensure the power supply can handle the machine's requirements.
5. Operating Instructions
Follow these steps for safe and effective welding:
- Power On: Turn on the welding machine using the power switch. The power indicator light will illuminate.
- Set Current: Use the welding current adjustment knob to set the desired amperage. The LCD display will show the selected current. Start with a lower current and adjust as needed based on the electrode size and material thickness.
- Prepare Workpiece: Clean the workpiece thoroughly to remove rust, paint, or grease, which can affect weld quality.
- Attach Earth Clamp: Securely attach the earth clamp to the workpiece, ensuring good electrical contact.
- Welding:
- Put on all required PPE, especially your welding helmet.
- Strike an arc by lightly tapping or scratching the electrode against the workpiece.
- Maintain a consistent arc length and travel speed. The anti-stick function helps prevent the electrode from fusing to the workpiece if it gets too close.
- Weld in a well-ventilated area.
- Post-Welding: After welding, turn off the machine. Allow the workpiece to cool before handling. Use the included wire brush to clean slag from the weld.

6. Maintenance
Regular maintenance ensures the longevity and safe operation of your welding machine:
- Cleaning: Regularly clean the machine's exterior with a dry cloth. Use compressed air to blow out dust from the ventilation openings. Ensure the machine is unplugged before cleaning.
- Cable Inspection: Periodically inspect all cables (power, electrode holder, earth clamp) for cuts, fraying, or damaged insulation. Replace damaged cables immediately.
- Terminal Connections: Check that all terminal connections are tight and free from corrosion.
- Storage: Store the welding machine in a dry, clean, and dust-free environment when not in use. Protect it from extreme temperatures.
7. Troubleshooting
If you encounter issues with your welding machine, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Machine does not power on | No power supply, faulty power cord, machine switch off | Check power outlet, inspect power cord, ensure machine switch is ON |
| No welding arc | Poor earth clamp connection, incorrect current setting, faulty electrode holder | Ensure earth clamp is secure, adjust current, check electrode holder connection |
| Machine overheats (Overheat/Overload indicator on) | Exceeded duty cycle, poor ventilation, prolonged use at high current | Allow machine to cool down, ensure proper ventilation, reduce welding time or current |
| Electrode sticks to workpiece | Low current setting, improper arc striking technique | Increase current, practice proper arc striking, utilize anti-stick feature |
| Poor weld quality | Incorrect current, wrong electrode, dirty workpiece, improper technique | Adjust current, use correct electrode, clean workpiece, refine welding technique |
If problems persist after attempting these solutions, please contact INGCO customer support or a qualified service technician.
