2. Safety Instructions

Welding operations involve significant risks. Always adhere to safety precautions to prevent injury or damage. This section outlines general safety guidelines; refer to local regulations and safety standards for comprehensive information.

• Electrical Shock: Welding current can cause severe or fatal electric shock. Ensure proper grounding, inspect cables for damage, and never operate in wet conditions. Wear dry gloves and protective clothing.
• Fumes and Gases: Welding fumes and gases can be hazardous to health. Work in a well-ventilated area or use local exhaust ventilation. Keep your head out of the fumes.
• Arc Rays: Arc rays can burn eyes and skin. Always wear a welding helmet with appropriate shade filter, safety glasses, and protective clothing (long sleeves, heavy gloves).
• Fire and Explosion: Welding sparks and hot metal can cause fires. Keep flammable materials away from the welding area. Have a fire extinguisher readily available.
• Hot Parts: Welded materials and equipment can remain hot for a long time. Use insulated gloves and allow parts to cool before handling.
• Noise: Some welding processes can generate high noise levels. Use hearing protection if necessary.

Always read and understand the entire manual before operating the machine.

4. Setup

Proper setup is crucial for safe and effective operation.

4.1 Power Connection

1. Ensure the machine's power switch is in the OFF position.
2. The TIG-205 PRO supports dual voltage (110V/220V). The machine automatically detects the input voltage. Connect the power cord to a suitable grounded electrical outlet.
3. Verify that the circuit breaker rating is sufficient for the welding current.

4.2 Gas Connection (TIG/Cold Welding)

For TIG and Cold Welding, pure argon shielding gas is required.

1. Securely connect one end of the gas hose to the gas inlet fitting on the rear of the welding machine.
2. Connect the other end of the gas hose to a suitable argon gas regulator attached to your argon cylinder.
3. Ensure all connections are tight to prevent gas leaks.
4. Set the gas flow rate on the regulator according to your welding application (typically 10-15 liters/minute for TIG).

4.3 Torch and Ground Clamp Connection

1. Connect the TIG torch power cable to the appropriate quick-connect fitting on the front panel (usually marked with a positive or negative symbol depending on the process).
2. Connect the TIG torch gas line to the gas outlet on the front panel.
3. Connect the ground clamp cable to the remaining quick-connect fitting on the front panel.
4. Attach the ground clamp securely to the workpiece or welding table, ensuring good electrical contact.

4.4 Electrode Holder Connection (for MMA Welding)

If performing MMA (Stick) welding, connect the electrode holder cable to the appropriate quick-connect fitting, typically opposite the ground clamp connection.

5. Operating Modes

The TIG-205 PRO offers multiple welding modes. Select the appropriate mode and adjust parameters via the control panel.

5.1 TIG Welding (AC/DC)

• DC TIG: Used for stainless steel, carbon steel, copper, and other non-ferrous metals. Provides a stable arc and good penetration.
• AC TIG: Essential for welding aluminum and magnesium alloys. The AC current helps to break up the oxide layer on the aluminum surface, ensuring a clean weld.
• HF Arc Starting: High-frequency ignition provides non-contact arc starting, preventing tungsten contamination of the workpiece.
• Pulse TIG: Improves weld quality on thin materials and reduces heat input, minimizing distortion. Adjustable pulse frequency and duty cycle.

Adjust welding current, AC balance (for aluminum), pulse frequency, and gas post-flow time according to the material thickness and desired weld characteristics.

5.2 Cold Welding

The Cold Welding mode is ideal for welding very thin materials (e.g., 0.04 inch aluminum, 0.015-0.12 inch stainless steel) with minimal heat input. This reduces material deformation and discoloration, resulting in silver-white welds for both aluminum and stainless steel. Pure argon shielding gas is mandatory for this process.

5.3 MMA (Stick) Welding

For MMA welding, select the MMA mode on the control panel. Insert the appropriate electrode into the electrode holder and adjust the welding current based on the electrode type and diameter, and the material thickness.

6. Maintenance

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

• Daily Checks: Inspect cables, torch, and ground clamp for damage. Ensure all connections are secure.
• Cleaning: Periodically clean the machine's exterior with a dry, soft cloth. Use compressed air to blow out dust from inside the machine (ensure power is disconnected).
• Consumables: Regularly check and replace worn-out tungsten electrodes, collets, collet bodies, and ceramic nozzles. A dull or contaminated tungsten electrode can lead to poor arc stability and weld quality.
• Gas System: Check gas hoses and connections for leaks. Ensure the gas regulator is functioning correctly.
• Storage: Store the welding machine in a clean, dry environment, away from excessive dust, moisture, and corrosive substances.
