7. Operating Instructions

7.1 General Operation

1. After making all connections, plug the machine into a suitable power outlet (AV90-240V).
2. Turn on the Power ON/OFF Switch (10).
3. The LED display (1) will light up.
4. Press the Mode Switching Button (5) to select either MMA or Lift TIG mode. The corresponding indicator (2 or 3) will illuminate.
5. Rotate the Current Regulation Knob (6) to adjust the welding current (10-200A) according to your material and electrode type.
6. For advanced settings like Arc Force, Hot Start, Anti-stick, or VRD, press the Current Regulation Knob (6) to cycle through the functions and then rotate to adjust their values.

7.2 MMA (Stick) Welding

The ARC200 Mini3 is designed for easy arc starting. It supports E7018/E6013 welding rods with diameters from 1.0mm to 3.2mm, and can weld materials up to 5mm thick.

1. Ensure the machine is set to MMA mode.
2. Select the appropriate welding current using the Current Regulation Knob.
3. Bring the electrode into contact with the workpiece to initiate the arc.
4. Maintain a consistent arc length and travel speed for a smooth weld bead.

7.3 Lift TIG Welding

For Lift TIG welding, ensure your TIG torch is connected and gas flow is established.

1. Ensure the machine is set to Lift TIG mode.
2. Select the appropriate welding current using the Current Regulation Knob.
3. Gently touch the tungsten electrode to the workpiece to initiate the arc, then lift it slightly to establish the arc.
4. Maintain a consistent arc length and feed filler rod as needed.

8. Specifications

9. Maintenance

Regular maintenance ensures the longevity and safe operation of your welding machine.

• Cleaning: Periodically clean the machine's exterior and ventilation openings to prevent dust and debris buildup. Use compressed air to blow out dust from inside the machine, ensuring power is disconnected first.
• Cable Inspection: Regularly inspect all welding cables, electrode holder, and ground clamp for any signs of damage, fraying, or loose connections. Replace damaged components immediately.
• Connection Tightness: Ensure all electrical connections are tight and secure.
• Storage: Store the welding machine in a dry, clean environment, away from moisture and extreme temperatures.

10. Troubleshooting

If you encounter issues with your welding machine, refer to the following common problems and solutions:

11. User Tips

• Practice Makes Perfect: Welding requires practice. Start with scrap metal to get a feel for the machine and different settings before tackling important projects.
• Cleanliness is Key: Always ensure your workpiece is free of rust, paint, oil, and other contaminants for the best weld quality and arc stability.
• Electrode Selection: For MMA welding, choose the correct electrode type and size for your material and desired penetration. The ARC200 Mini3 is optimized for E7018 and E6013 electrodes.
• TIG Gas Flow: For Lift TIG, ensure a consistent flow of inert gas (typically Argon) to protect the weld puddle from atmospheric contamination.
• Personal Protective Equipment (PPE): Never compromise on safety. Always wear a welding helmet, gloves, and protective clothing.

12. Warranty and Support

The HITBOX ARC200 Mini3 welding machine comes with a 1-year warranty. For warranty claims, technical support, or service inquiries, please contact your retailer or the manufacturer directly. Keep your purchase receipt as proof of purchase.
