4.2. Key Features

Figure 4: Multiple Advantages of the TIG200

• Dual Voltage: Supports both 110V and 220V input.
• Good Heat Dissipation: Efficient cooling system for extended operation.
• Hot Start: Provides an initial boost of current to prevent the electrode from sticking.
• Arc Force: Helps maintain a stable arc and prevents sticking, especially with longer arc lengths.
• Anti-stick: Reduces the current if the electrode sticks, making it easier to detach.
• Latest IGBT Technology: Ensures stable arc, less spatter, and high efficiency.
• Overcurrent Protection: Safeguards the machine from excessive current.
• High Duty Cycle: Allows for longer welding periods without overheating.
• Post Gas Function: Variable air post time (1-10 seconds) from the torch helps cool the torch and consumables, enhancing their durability.

5. Setup

Before operating the machine, ensure proper connections for your chosen welding mode.

5.1. MMA/ARC Welding Setup

1. Ensure the machine's power switch (A) is OFF.
2. Connect the Electrode Holder cable to the Positive Terminal (+) on the front panel.
3. Connect the Ground Clamp cable to the Negative Terminal (-) on the front panel.
4. Attach the ground clamp securely to the workpiece or welding table.
5. Insert a suitable welding electrode into the electrode holder.
6. Switch the welding mode button (4) to 'ARC'.
7. Connect the machine to the appropriate power supply (110V or 220V).
8. Turn on the machine's power switch (A).

5.2. HF TIG Welding Setup

1. Ensure the machine's power switch (A) is OFF.
2. Connect the TIG Torch cable to the TIG Torch Connection (9) on the front panel.
3. Connect the TIG Torch trigger cable to the Torch Switch (8) connection.
4. Connect the Ground Clamp cable to the Positive Terminal (+) on the front panel.
5. Attach the ground clamp securely to the workpiece or welding table.
6. Connect the gas hose (4) from your inert gas cylinder (e.g., Argon) to the 'Gas In' (B) connection on the rear panel. Ensure the gas cylinder valve is closed before connecting.
7. Install the appropriate tungsten electrode and consumables (collet, collet body, ceramic nozzle) into the TIG torch.
8. Switch the welding mode button (4) to 'TIG'.
9. Connect the machine to the appropriate power supply (110V or 220V).
10. Turn on the machine's power switch (A).
11. Open the gas cylinder valve and set the desired gas flow rate on the regulator.

6. Operating Instructions

6.1. MMA/ARC Welding Operation

1. After completing the MMA setup (Section 5.1), turn on the machine.
2. Select 'ARC' mode using the welding mode button (4).
3. Adjust the welding current using the Current Adjustment Knob (A) according to the electrode type and material thickness. The current display (1) will show the set value.
4. Begin welding, maintaining a consistent arc length and travel speed.
5. After welding, use the brush and hammer (8) to remove slag.

6.2. HF TIG Welding Operation

1. After completing the TIG setup (Section 5.2), turn on the machine and open the gas valve.
2. Select 'TIG' mode using the welding mode button (4).
3. Adjust the welding current using the Current Adjustment Knob (A) based on the material type and thickness.
4. Set the Post Gas time using the Post Gas Adjustment Knob (S). A post-flow time of 5-10 seconds is generally recommended to protect the weld puddle and tungsten from atmospheric contamination as it cools.
5. Initiate the arc by pressing the TIG torch trigger. The High Frequency (HF) start will create a non-contact arc, preventing tungsten contamination.
6. Maintain a consistent arc length and feed the filler rod (if used) into the weld puddle.
7. Release the trigger to stop welding. The post-flow gas will continue for the set duration.

6.3. Welding Applications

The TIG200 is suitable for welding various materials, including:

• Mild Steel
• Stainless Steel
• Steel Plate
• Square Pipe
• Carbon Steel
• Copper

7. Maintenance

Regular maintenance ensures the longevity and optimal performance 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 ventilation openings.
• Connections: Regularly check all cable connections for tightness and signs of wear or damage. Replace damaged cables immediately.
• TIG Torch: Inspect the TIG torch consumables (tungsten, collet, collet body, ceramic nozzle) for wear and replace as needed. Ensure the tungsten is properly sharpened.
• Ground Clamp: Keep the ground clamp clean and ensure it makes good electrical contact with the workpiece.
• Storage: Store the machine in a dry, dust-free environment when not in use.

10. User Tips

• Practice Makes Perfect: If you are new to welding, start with scrap pieces of metal to get a feel for the machine and different settings.
• Cleanliness is Key: Always ensure your workpiece is clean and free of rust, paint, or oil for the best weld quality, especially with TIG welding.
• Gas Flow for TIG: Proper inert gas flow is crucial for TIG welding. Too little gas can lead to porosity, while too much can cause turbulence and draw in atmospheric contaminants.
• Electrode Selection: Choose the correct electrode type and diameter for your material and desired current in MMA welding.
• Tungsten Preparation: For TIG welding, ensure your tungsten electrode is properly ground to a sharp point for precise arc control.
