2. Safety Information
Welding operations involve significant risks. Always adhere to safety precautions to prevent injury or damage to equipment. This machine is engineered with triple-layer safety safeguards: over-voltage, over-current, and over-heat protection.
- Electrical Safety: Ensure proper grounding. Do not operate in wet conditions. Verify input voltage (110V/220V) matches the power supply.
- Fume Hazards: Weld in well-ventilated areas. Avoid inhaling welding fumes.
- Arc Rays: Wear appropriate welding helmets with proper shade filters to protect eyes and face from intense light and UV/IR radiation.
- Burn Prevention: Wear protective clothing, gloves, and footwear to prevent burns from hot metal and sparks.
- Fire Prevention: Keep flammable materials away from the welding area. Have a fire extinguisher readily available.
- Gas Cylinders: Secure gas cylinders properly. Use correct regulators and hoses.

5.2 Welding Modes
The TIG-200 ACDC offers 8-in-1 multi-process welding capabilities:
- Stick Welding (MMA): For general purpose welding with coated electrodes.
- DC TIG: For welding stainless steel, carbon steel, copper, and other DC-weldable metals.
- DC Pulse TIG: Provides enhanced control for thinner materials and reduced heat input.
- AC TIG: Essential for welding aluminum and magnesium alloys, providing cleaning action.
- AC Pulse TIG: Combines AC TIG benefits with pulse control for precise aluminum welding.
- Lift TIG: A simplified TIG start method, reducing tungsten contamination.
- Cold Welding: Designed for low-heat welding and thin materials, minimizing thermal distortion and spatter.
- Spot Welding: For quick, localized welds.

5.3 Parameter Adjustments
The control panel allows for fine-tuning of various welding parameters:
- Pre-flow: Duration of gas flow before arc ignition.
- Initial Current: Starting amperage for the weld.
- Up-slope: Time taken to ramp up from initial current to peak current.
- Peak Current: Maximum welding amperage.
- Base Current: Minimum amperage during pulse welding.
- Down-slope: Time taken to ramp down from peak current to crater current.
- Crater Current: Amperage at the end of the weld to fill the crater.
- Post-flow: Duration of gas flow after arc extinction to protect the weld puddle.
- Pulse Duty: Percentage of time spent at peak current during pulse welding.
- AC Frequency: Controls the arc cone width and direction for AC TIG.
- AC Balance: Adjusts the cleaning action and penetration for AC TIG.
- Pulse Frequency: Number of pulses per second.

5.4 Remote Control
The TIG torch is equipped with a built-in remote control button, allowing for on-the-fly amperage adjustments without interrupting the welding process. This enhances efficiency, especially for high-volume or precision tasks.

5.5 Cold TIG Welding
The Cold TIG feature is specifically designed for welding thin materials with minimal heat input. This reduces thermal distortion and ensures spatter-free results, making it ideal for heat-sensitive applications.

6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your welding machine.
- Cleaning: Periodically clean the machine's exterior and ventilation openings to prevent dust and debris buildup. Use compressed air to clear internal components if necessary, ensuring the machine is unplugged.
- Cable Inspection: Regularly inspect all cables, hoses, and connections for wear, damage, or loose fittings. Replace damaged components immediately.
- TIG Torch Maintenance: Clean the collet, collet body, and gas lens. Replace worn tungsten electrodes and ceramic nozzles as needed.
- Storage: Store the welder in a dry, clean environment when not in use.
7. Troubleshooting
If you encounter issues, refer to the following common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| No power | Power cable disconnected, circuit breaker tripped, machine fault | Check power connections, reset circuit breaker, contact support if issue persists. |
| No arc | Poor ground connection, incorrect settings, faulty torch switch | Ensure ground clamp is secure, verify welding parameters, check torch connections. |
| Poor weld quality | Incorrect parameters, insufficient gas flow, contaminated tungsten/material | Adjust welding parameters, check gas supply and flow rate, clean tungsten and workpiece. |
| Overheat protection activated | Exceeded duty cycle, blocked ventilation | Allow machine to cool down, ensure clear ventilation paths. |
For issues not resolved by these steps, please contact ANDELI customer support.
