8. Troubleshooting
This section addresses common issues you might encounter. For problems not listed here, contact customer support.
| Problem | Possible Cause | Solution |
|---|---|---|
| Machine does not power on | No power supply; Power switch off; Internal fault | Check power cord and outlet; Ensure power switch is ON; Contact support if fault persists. |
| No arc/Poor arc stability | Improper connections; Worn consumables; Incorrect settings; Insufficient gas/air supply | Check all cable connections; Replace worn plasma tips/TIG electrodes; Adjust current/voltage settings; Verify gas/air pressure. |
| Overload indicator active | Exceeded duty cycle; Insufficient cooling | Allow machine to cool down; Ensure ventilation is not blocked. The machine has an overload protection system. |
| Plasma cutting not clean/deep enough | Incorrect current; Worn plasma tip/electrode; Insufficient air pressure; Too fast travel speed | Increase current; Replace consumables; Adjust air pressure to 0.4-0.6 MPa; Reduce travel speed. |
| TIG welding on aluminum not possible | This model is DC TIG only. Aluminum requires AC TIG welding. | This machine is designed for DC TIG welding of stainless steel, carbon steel, and other non-ferrous metals (excluding aluminum for TIG). |
9. User Tips
- Gas for Plasma Cutting: Plasma cutting requires compressed air, not a special gas. Ensure your air compressor can provide consistent pressure between 0.4-0.6 MPa.
- Gas for TIG Welding: TIG welding requires a shielding gas, typically Argon, to protect the weld puddle from atmospheric contamination.
- Aluminum Welding: While the machine can weld non-ferrous metals with MMA, for TIG welding aluminum, an AC TIG machine is generally required. This model is primarily for DC TIG applications.
- Model Differences: The 'F' in 520TSCPF indicates the inclusion of a Pulse function, which offers greater control and improved weld quality, especially for thinner materials in TIG mode, compared to models without 'F'.
- Noise Reduction: The machine incorporates noise reduction technology with a sound insulation board to minimize operational noise.
