- Connect the WP-26 aluminum torch (4m) to the appropriate front panel connector.
- Attach the grounding clamp (2m) to the negative pole.
- Connect the foot switch to the designated two-core connector for remote control.
- Install the appropriate nozzle, collet, and tungsten pole for your welding task. The package includes 10 nozzles, 10 collets, and 10 tungsten poles.
5. Operating Instructions
The TIG-250PLS offers four main welding modes: Pulse TIG, HF TIG, Cold Pulse, and Cold Welding. The control panel provides a clear digital display and an adjustment knob for setting parameters.
5.1 General Operation
- Turn on the machine using the ON/OFF switch on the rear panel.
- Select the desired welding mode (AC, DC, 2T, 4T, Cold, Pulse) using the buttons on the left side of the control panel.
- Use the adjustment knob and arrow buttons to set welding parameters such as current, frequency, pulse width, pre-flow, post-flow, rise, base, and crater. The digital display will show the current settings.
5.2 Welding Modes and Applications
5.2.1 AC TIG Welding
Suitable for welding aluminum and its alloys. The AC mode provides a cleaning action that helps remove oxides from the aluminum surface.
5.2.2 DC TIG Welding
Ideal for welding stainless steel, carbon steel, copper, and titanium. Provides a stable arc and deep penetration.
5.2.3 Pulse TIG Welding
Used for welding thinner materials or when heat input needs to be controlled to minimize distortion. Available in both AC and DC modes.
5.2.4 Cold Welding (AC Cold / DC Cold)
This mode is designed to reduce deformation and discoloration, resulting in silver-white welds on aluminum and stainless steel. It is particularly effective for thin materials.
- AC Cold Spot Welding: Suitable for thin aluminum plates (e.g., 0.04 inch seamless aluminum plate).
- DC Cold Spot Welding: Suitable for sheet metal welding with minimal discoloration and no need for sanding.
- DC Cold Welding Interval: Allows for rapid continuous spot welding on sheet metal.
5.3 Memory Function
The machine features a memory function to save and recall welding parameters. This allows for quick setup of frequently used settings.
6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your welding machine.
- Cleaning: Periodically clean the machine's exterior and ventilation openings to prevent dust and debris buildup. Use a dry, soft cloth. Do not use solvents or abrasive cleaners.
- Connections: Regularly check all electrical and gas connections for tightness and signs of wear.
- Torch and Consumables: Inspect the welding torch, nozzles, collets, and tungsten electrodes for wear and replace them as needed.
- Storage: Store the machine in a dry, clean environment when not in use.
Always disconnect the machine from the power supply before performing any cleaning or maintenance.
7. Troubleshooting
If you encounter any issues with your ANDELI TIG-250PLS welding machine, please refer to the following general advice:
- No Power: Check the power cable connection, the ON/OFF switch, and the circuit breaker. Ensure the correct voltage (110V/220V) is selected and supplied.
- No Arc: Verify gas flow, check torch connections, ensure the tungsten electrode is properly installed and sharpened, and confirm work clamp is securely attached to the workpiece.
- Poor Weld Quality: Review your welding parameters (current, frequency, pulse settings), gas flow, and electrode condition. Ensure the workpiece is clean.
For persistent issues or complex problems, please contact customer service for free guidance.
