6. Operation
The HITBOX ARC200S is a 2-in-1 welding machine capable of ARC/MMA and LIFT TIG welding. It features an intelligent digital display for easy monitoring and adjustment.
6.1 Powering On and Mode Selection
- Turn on the main power switch. The LED display will illuminate.
- Use the mode selection button (indicated on the display, e.g., "MMA" or "LIFT TIG") to choose your desired welding process.
6.2 Adjusting Welding Parameters
- Current Adjustment: Use the main knob to adjust the welding current (Amperage) as displayed on the LED screen. Refer to the specifications for appropriate current ranges for MMA and Lift TIG.
- Electrode Size/Thickness: The display shows recommended electrode sizes and welding thickness. Adjust current accordingly.
- Feature Toggles: The display includes toggles for "Hot Start", "Arc Force", "VRD" (Voltage Reduction Device), and "Anti-stick". Activate or deactivate these features as needed for your welding task.
- Hot Start: Provides an initial boost of current to help ignite the arc easily.
- Arc Force: Prevents the electrode from sticking to the workpiece by increasing current when the arc length becomes too short.
- VRD (Voltage Reduction Device): Reduces the open-circuit voltage for increased safety, especially in damp conditions.
- Anti-stick: Automatically reduces the current if the electrode sticks, allowing it to be easily removed without damaging the electrode holder.
6.3 Welding Process (General)
- Ensure proper grounding of the workpiece.
- Position yourself comfortably and safely.
- Initiate the arc according to the selected welding mode (MMA or Lift TIG).
- Maintain a consistent arc length and travel speed for optimal weld quality.
- The integrated system synergy chip technology automatically matches the starting arc current while adjusting for metal thickness, simplifying operation.
7. Maintenance
Regular maintenance ensures the longevity and safe operation of your welding machine.
- Cleaning: Periodically clean the machine's exterior with a dry cloth. Use compressed air to blow out dust and debris from the cooling vents. Ensure the machine is unplugged before cleaning.
- Cable Inspection: Regularly inspect welding cables, electrode holder, and earth clamp for damage, fraying, or loose connections. Replace damaged components immediately.
- Storage: Store the welding machine in a dry, clean environment, away from excessive dust, moisture, and corrosive materials.
- Fan Operation: Ensure the cooling fan is free from obstructions and operating correctly to prevent overheating.
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; faulty power cable; internal fuse blown. | Check power connection and outlet; inspect power cable; contact service for fuse replacement. |
| No arc or weak arc | Poor ground connection; incorrect current setting; damp electrodes; faulty electrode holder. | Ensure solid ground connection; adjust current; use dry electrodes; check electrode holder. |
| Electrode sticks frequently | Low current setting; improper arc length; Anti-stick feature off. | Increase current; maintain proper arc length; ensure Anti-stick is enabled. |
| Overheating indicator (alarm LED) active | Exceeded duty cycle; blocked ventilation; high ambient temperature. | Allow machine to cool down; clear ventilation openings; operate in a cooler environment. |
9. User Tips
- For beginners, start with lower current settings and practice on scrap metal to get a feel for the machine.
- Always ensure your workpiece is clean and free of rust, paint, or oil for the best weld quality and arc stability.
- Utilize the "Hot Start" and "Arc Force" features, especially when using difficult-to-start electrodes or welding in challenging positions.
- The lightweight and portable design (Figure 7) makes it easy to move the welder to different job sites.
