2. Safety Instructions

Always prioritize safety when operating welding equipment. Failure to follow these safety guidelines can result in serious injury or death.

• Personal Protective Equipment (PPE): Always wear a welding helmet with appropriate shade, flame-resistant clothing, welding gloves, and safety shoes.
• Ventilation: Ensure adequate ventilation to remove welding fumes and gases from the work area.
• Fire Prevention: Keep a fire extinguisher nearby. Remove all flammable materials from the welding area.
• Electrical Safety: Ensure the machine is properly grounded. Do not operate in wet conditions. Inspect cables and connections for damage before each use.
• Gas Cylinders: Secure gas cylinders to prevent them from falling. Use the correct gas for the welding process (e.g., pure argon for Cold welding).
• Eye and Skin Protection: Welding arcs emit intense UV and IR radiation that can cause severe burns to eyes and skin.
• Children and Bystanders: Keep children and unauthorized personnel away from the welding area.

3. Product Features

The ANDELI TIG-250PLS welding machine offers a range of advanced features for various welding applications:

• Multi-Functionality: Supports TIG welding, Pulse welding, Cold welding, Clean function, Auto, and Au-Ag welding modes.
• Cold Welding Mode: Specifically designed to reduce deformation and minimize discoloration, resulting in a silver-white weld bead on stainless steel. Requires pure argon gas.
• Wide Material Compatibility: Suitable for ordinary thin steel, iron, stainless steel, cast iron, and processing of gold and silver jewelry. Note: Not suitable for aluminum welding.
• Cleaning Function: Cleans the weld surface to restore the original bright appearance of the weld bead. A cleaning solution (e.g., HCl with 0.175% to 0.035% concentration) must be purchased locally.
• Safety Certified: CE certified for safety and quality assurance.

5. Setup

1. Unpacking: Carefully remove the welding machine and all accessories from the packaging. Inspect for any shipping damage.
2. Placement: Place the machine on a stable, level surface in a well-ventilated area, away from flammable materials.
3. Power Connection: Ensure the ON/OFF switch is in the "OFF" position. Connect the power cable to a suitable 220V Europlug outlet.
4. Gas Connection:
   • Connect the gas regulator to your argon gas cylinder.
   • Attach one end of the gas pipe to the gas regulator and the other end to the M10 Gas Tube Connector on the rear of the welding machine.
   • Ensure all gas connections are tight to prevent leaks.
5. Torch and Ground Clamp Connection:
   • Connect the TIG torch (WP-9F 4M or QQ-150 4M) to the Gas-power Connector and Two-core Connector on the front panel.
   • Connect the ground clamp cable to the Negative Pole (-) terminal.
   • Attach the ground clamp securely to the workpiece or welding table to ensure a good electrical connection.
6. Tungsten Electrode Installation: Install the appropriate tungsten electrode into the TIG torch collet, ensuring it is properly sharpened and extends the correct length.

6. Operating Instructions

After completing the setup, you can begin operating the machine. Always refer to the specific parameters for your welding task.

Figure 5: Visual Examples of Welding Functions

This image provides visual examples of the different welding functions: TIG (HF), Pulse, Cold, Clean, and Au/Ag, demonstrating their application.

General Operation Steps:

1. Power On: Turn the ON/OFF switch to the "ON" position. The display screen will illuminate.
2. Select Function: Use the Function Selector knob on the front panel to choose your desired welding mode (TIG, Pulse, Cold, Clean, Auto, Au-Ag).
3. Adjust Parameters: Use the Adjustment Knobs to set the current (A), frequency (Hz), and other relevant parameters according to the material thickness and welding requirements. Refer to the Specifications table for typical ranges.
4. Gas Flow: Open the valve on the argon gas cylinder and adjust the flow rate on the regulator.
5. Begin Welding: With proper PPE, initiate the arc and begin welding.
6. Power Off: After welding, turn off the machine and close the gas cylinder valve.

Specific Function Notes:

• TIG Welding: Standard TIG process for precise welds.
• Pulse Welding: Provides better control over heat input, useful for thin materials or out-of-position welding. Adjust pulse frequency as needed.
• Cold Welding: Ideal for minimizing heat deformation and discoloration, especially on stainless steel. Ensure pure argon gas is used.
• Clean Function: Use with the appropriate cleaning solution to prepare or finish weld surfaces.
• Au-Ag Welding: Specialized mode for gold and silver jewelry processing.
