4. Setup and Installation

4.1 Power Connection (Dual Voltage)

The TIG-250MPL supports dual voltage input (110V/220V), offering flexibility for various operational environments. Ensure the correct power plug and conversion line are used for your specific power supply.

Figure 4: The TIG-250MPL supports both 110V and 220V power inputs.

4.2 Torch and Ground Clamp Installation

Follow these steps to properly install the welding torches and ground clamp:

1. Install WP-17F Hot Welding Gun:

   Connect the quick plug of the WP-17F TIG torch to the negative terminal on the machine. Connect the two-pin plug to the corresponding two-pin port. Then, connect the ground clamp to the positive terminal.

4.3 Gas Bottle and Regulator Installation

Proper gas connection is crucial for TIG and Cold welding. Follow these steps:

1. Tighten the Argon Regulator:

   Securely tighten the argon regulator to the gas bottle. Ensure a tight seal to prevent gas leaks.

2. Connect Air Tube:

   Connect one side of the air tube to the argon regulator. Connect the other side of the air tube to the interface located behind the main body of the welding machine.

5. Operating Instructions

5.1 Function Panel Overview

The TIG-250MPL features a user-friendly control panel for easy operation and parameter adjustment.

5.2 Argon Arc Welding (TIG DC) Settings

To adjust TIG DC welding parameters:

1. Switch to DC mode under the TIG function.
2. Adjust the welding current (maximum 250A).
3. Adjust the post-flow time (e.g., to 2 seconds) and pre-flow time (e.g., to 0.3 seconds).

Example of TIG DC welding on 3.0mm stainless steel plate:

5.3 Argon Arc Pulse Welding Settings

To adjust TIG Pulse welding parameters:

1. Select PULSE mode under the TIG function.
2. Adjust the duty ratio, frequency, base current, pre-flow, and post-flow settings.

Example of TIG Pulse welding on 3.0mm stainless steel plate:

5.4 Cold Welding Settings and Effects

Cold welding can be performed in single (spot welding) or continuous modes. This mode is ideal for reducing deformation and discoloration, resulting in a silver-white stainless steel welding bead. Pure argon gas is required for cold welding.

1. Single (Spot Welding) Mode:

   Adjust the welding current, welding time, and interval for precise spot welds.

2. Continuous Welding Mode:

   Adjust the welding current, welding time, and interval for continuous welding. Also adjust pre-flow and post-flow.

Example of Cold welding on 1.0mm stainless steel plate:

5.5 Parameter Storage and Retrieval

The TIG-250MPL allows you to store and retrieve up to 10 groups of commonly used parameters for quick access.

1. Saving Parameters:

   Adjust the desired parameters. Long press the "Save" button for 3 seconds to store the current settings into a group channel.

2. Retrieving Parameters:

   To retrieve stored parameters, hold the "Retrieval" button for one second until the light illuminates. Rotate the adjustment knob to select the desired group channel (e.g., group 10). The machine will then display the saved parameters.

Figure 7: The memory storage feature allows for convenient saving and direct use of up to 10 parameter groups.

7. Maintenance

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

• Keep the machine clean and free from dust and debris. Use compressed air to clear ventilation openings.
• Inspect cables and connections regularly for wear, damage, or loose fittings. Replace any damaged components immediately.
• Check the welding torch consumables (nozzles, collets, tungsten electrodes) for wear and replace as needed.
• Ensure proper gas flow and check for leaks in the gas lines.
• Store the welder in a dry, clean environment when not in use.

8. Troubleshooting

If you encounter issues with your TIG-250MPL, refer to the following common troubleshooting tips:

• No Power: Ensure the power cable is securely connected and the power switch is ON. Verify the power source voltage matches the machine's requirements.
• No Arc: Check all cable connections, including the ground clamp and torch connections. Ensure the tungsten electrode is properly installed and sharpened. Verify gas flow.
• Poor Weld Quality: Adjust welding parameters (current, pulse settings, cold welding time/interval) according to the material thickness and desired weld. Ensure proper gas shielding and clean workpiece surfaces.
• Overheating: Allow the machine to cool down if the thermal overload indicator activates. Ensure proper ventilation and avoid exceeding the duty cycle.
