4. Product Overview
The Genérico Professional Inverter Welder x120 is a powerful and versatile welding machine designed for high-quality metal fabrication, repairs, and heavy construction projects. It features advanced IGBT technology for precise and uniform welding, a digital display for easy parameter control, and supports both MMA (Shielded Metal Arc Welding) and DC (Direct Current) welding.

5. Setup
Follow these steps for the initial setup of your inverter welder:
- Unpacking: Carefully remove the welder and all accessories from the packaging. Inspect for any damage.
- Power Connection: Connect the welder to a suitable wired electric power source (230V, 50/60 Hz). Ensure the power switch on the welder is in the OFF position before connecting.
- Ground Clamp Connection: Attach the negative electrode holder clamp to the appropriate terminal on the welder. Securely connect the ground clamp to the workpiece or welding table to ensure a good electrical connection.
- Electrode Holder Connection: Connect the electrode holder to the positive terminal on the welder. Insert an appropriate electrode into the holder.
- Welding Mask Assembly: Assemble the welding mask if it came disassembled. Ensure the protective lens is correctly installed.
6. Operating Instructions
Before operating, ensure all safety precautions are followed and the setup is complete.
- Power On: Turn on the welder using the power switch. The digital display will illuminate.
- Adjust Current: Use the control knob to set the desired welding current (Amperes) based on the electrode size and material thickness. The digital display provides precise feedback.
- Prepare Workpiece: Ensure the workpiece is clean and free of rust, paint, or grease. Secure the ground clamp firmly to the workpiece.
- Start Welding: Put on your welding mask and protective gear. Bring the electrode into contact with the workpiece to strike an arc. Maintain a consistent arc length and travel speed for a smooth weld bead.
- Monitor Performance: The IGBT technology ensures stable arc performance. Adjust current as needed during welding.
- Post-Weld Cleaning: After welding, use the chipping hammer to remove slag and the brush to clean the weld area.

7. Maintenance
Regular maintenance ensures the longevity and optimal performance of your welder:
- Cleaning: Regularly clean the exterior of the welder with a dry cloth. Ensure ventilation openings are free from dust and debris. Use compressed air to clean internal components if necessary, ensuring the unit is unplugged.
- Cable Inspection: Periodically inspect all cables (power, ground, electrode holder) for cuts, fraying, or damage. Replace damaged cables immediately.
- Terminal Check: Ensure all electrical connections and terminals are tight and free from corrosion.
- Storage: Store the welder in a dry, clean environment when not in use.
8. Troubleshooting
Refer to this section for common issues and their solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Welder does not power on | No power supply; Power switch off; Internal fuse blown | Check power outlet and cable; Turn on power switch; Contact qualified service personnel |
| No arc or weak arc | Poor ground connection; Incorrect current setting; Wet or damaged electrode; Faulty electrode holder | Ensure solid ground connection; Adjust current; Use dry, undamaged electrodes; Inspect/replace electrode holder |
| Overheating indicator on | Exceeded duty cycle; Poor ventilation | Allow welder to cool down; Ensure clear airflow around the unit |
