2. Gas Connection: Connect your pure argon gas cylinder to the Gas Tube Connector on the rear panel. Ensure all connections are secure to prevent leaks.
3. Torch and Ground Clamp: Attach your TIG torch and ground clamp to the appropriate connectors on the front panel (Note: BARE package does not include torch and accessories).
4. Workpiece Preparation: Clean the workpiece thoroughly to remove any rust, paint, or contaminants that could affect weld quality.

Operating Instructions

The TIG-250PL offers multiple welding modes for various applications. Refer to the control panel diagram (Figure 4) for button locations.

Mode Selection

• AC Mode: Suitable for aluminum and magnesium alloys.
• DC Mode: Ideal for stainless steel, carbon steel, copper, and other non-ferrous metals.
• 2T/4T:
  • 2T (Two-Touch): Press and hold the torch trigger to weld, release to stop.
  • 4T (Four-Touch): Press and release to start welding, press and release again to stop. Useful for longer welds.
• Cold Welding Mode: Minimizes heat input, reducing deformation and discoloration. Ideal for thin materials.
• Pulse Mode: Provides pulsed current for better control over heat input, especially for thin materials or when precise control is needed.
• Save Function (M): Allows saving and recalling preferred welding parameters.

Welding Modes and Applications

Figure 7: Examples of welding results for AC Cold (0.5mm Aluminum), AC Pulse (3mm Aluminum), AC Hot TIG (3mm Aluminum), DC Cold (0.5mm Stainless Steel), DC Pulse (3mm Stainless Steel), and DC Hot TIG (1mm Square Tube).

• AC Cold Spot Welding: Ideal for thin aluminum welding, minimizing heat input.
• AC Argon Arc Pulse: Suitable for quick welding of aluminum plates, providing controlled heat.
• DC Cold Spot Welding: Focuses on sheet welding with minimal discoloration and no need for sanding.
• DC Cold Welding Interval: Allows for rapid continuous spot welding on sheet metal.
• DC TIG Spot Welding: Suited for thick plate welding, offering strong penetration.
• DC Argon Arc Pulse: Designed for fast welding of thick plates, ensuring efficient heat management.

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 regularly.
• Inspect all cables and connections for wear or damage before each use. Replace any damaged components immediately.
• Ensure proper gas flow and check for leaks in the gas lines.
• Store the machine in a dry, clean environment when not in use.
