5. Controls and Display

The AIXZ AIT200P features an intuitive control panel for easy operation. Refer to the diagram below for component identification:

1. Welding Mode Button: Selects between AC TIG, DC TIG, and MMA (ARC) welding modes.
2. Pulse Button (ON/OFF): Activates or deactivates the pulse welding function.
3. Welding Torch Switch Button: Toggles between 2T (Two-Touch), 4T (Four-Touch), and SPOT welding modes.
4. VRD Button (ON/OFF): Controls the Voltage Reduction Device for enhanced safety.
5. Data Adjustment Knob: Used to adjust parameters such as Amperage, Time, and Frequency.
6. Welding Function Button: Selects additional welding functions like ARC Force and Hot Start.

6. Setup

Before operating the welding machine, ensure proper setup and connections.

6.1 Power Connection

• Connect the welding machine to a suitable power supply (110V or 220V, 50/60Hz) as indicated on the machine's label.
• Ensure the power outlet is properly grounded and capable of handling the machine's rated input current.

6.2 Gas Connection (for TIG welding)

• Connect the gas hose from your inert gas cylinder (e.g., Argon) to the gas inlet on the rear of the welding machine.
• Ensure all gas connections are secure to prevent leaks.

6.3 Torch and Ground Clamp Connection

• Connect the TIG torch or electrode holder to the appropriate terminals on the front panel of the machine.
• Connect the earth clamp to the workpiece or welding table, ensuring good electrical contact.

6.4 Optional Foot Pedal Connection

If using the optional foot pedal, connect its 5-prong connector to the corresponding port on the front panel of the welding machine.

The foot pedal allows for precise control of welding current: tap to activate gas contactor and increase current; release to close gas contactor and decrease current.

7. Operating Modes

The AIXZ AIT200P supports multiple welding processes and modes:

7.1 TIG Welding (AC TIG / DC TIG)

• AC TIG: Ideal for welding aluminum and magnesium alloys. Provides cleaning action to remove oxides.
• DC TIG: Suitable for welding stainless steel, carbon steel, copper, and titanium. Offers deep penetration and a stable arc.

7.2 MMA (ARC) Welding

Used for welding various ferrous metals with coated electrodes. The machine's Arc Force and Hot Start features enhance arc stability and ease of ignition.

7.3 Pulse Welding

The Pulse function (ON/OFF button) allows for better control of heat input, reducing distortion and improving weld quality, especially on thin materials or when welding out of position.

7.4 Torch Switch Modes (2T/4T/SPOT)

• 2T (Two-Touch): Press and hold the torch trigger to start welding; release to stop.
• 4T (Four-Touch): Press and release to start, press and release again to stop. This mode is useful for long welds, reducing operator fatigue.
• SPOT: For precise, short-duration spot welds.

7.5 Material Compatibility

The AIXZ AIT200P is suitable for welding a variety of materials:

• Stainless Steels
• Aluminum
• Copper
• Carbon Steel
• Low-Alloy Steel
• Titanium

8. Maintenance

Regular maintenance ensures the longevity and optimal performance of your welding machine.

8.1 Cleaning

• Periodically clean the machine's exterior with a dry cloth.
• Ensure the cooling vents are free from dust and debris to maintain efficient heat dissipation.
• The machine features a durable dust cover that minimizes corrosion on internal components.

8.2 Cooling System

The AIT200P is equipped with a quiet and efficient heat dissipation system. Ensure adequate airflow around the machine during operation to prevent overheating.

8.3 Consumables

Regularly inspect and replace TIG torch consumables (tungsten electrodes, collets, collet bodies, ceramic nozzles) as they wear out to maintain weld quality.

9. Troubleshooting

This section provides general guidance for common issues. For complex problems, contact customer support.

• No Power: Check power cable connection, main power switch, and circuit breaker.
• No Arc: Ensure proper grounding, correct electrode/tungsten setup, and sufficient gas flow (for TIG). Verify welding parameters are set correctly.
• Poor Weld Quality: Adjust welding current, voltage, wire feed speed (if applicable), gas flow, and travel speed. Check for contaminated base metal or incorrect consumables.
• Overheating: Allow the machine to cool down. Ensure cooling vents are clear and the duty cycle is not exceeded.

10. User Tips

Based on general welding practices, here are some tips for using your AIXZ AIT200P:

• Practice Regularly: Consistent practice is key to improving your welding skills and achieving high-quality welds.
• Cleanliness is Crucial: Always ensure your workpiece is clean and free of oil, rust, and paint, especially for TIG welding, to prevent contamination and ensure strong welds.
• Proper Gas Flow: For TIG welding, maintain the correct shielding gas flow rate to protect the weld puddle from atmospheric contamination.
• Tungsten Preparation: Sharpen your tungsten electrode to the appropriate angle for the material and current type (AC or DC) to achieve a stable arc and good penetration.
• Start with Lower Amperage: When unsure of settings, start with a lower amperage and gradually increase it until you achieve the desired penetration and bead appearance.
