2. Safety Information

WARNING: Welding can be dangerous. Always follow safety precautions to prevent injury or death.

• Electric Shock: Welding current can kill. Do not touch live electrical parts. Wear dry, insulating gloves and clothing. Ensure the workpiece is properly grounded.
• Fumes and Gases: Welding fumes and gases can be hazardous to your health. Keep your head out of the fumes. Use enough ventilation and/or exhaust at the arc to keep fumes and gases away from the breathing zone.
• Arc Rays: Arc rays can injure eyes and burn skin. Wear an approved welding helmet with a proper shade filter. Wear protective clothing, including long sleeves and pants, and leather gloves.
• Fire and Explosion: Welding sparks and hot materials can cause fire or explosion. Keep flammable materials away from the welding area. Have a fire extinguisher readily available.
• Hot Parts: Welded parts and equipment can be hot. Allow them to cool before touching.
• Noise: Excessive noise can damage hearing. Wear ear protection.
• Pacemakers: Magnetic fields from high currents can affect pacemakers. Consult your doctor before welding.

4. Setup

Proper setup is crucial for safe and effective welding. Ensure all connections are secure before powering on the machine.

1. Power Connection: Connect the welding machine to a 380V power supply. Ensure the power source meets the machine's requirements.
2. Ground Clamp Connection: Attach the ground clamp cable to the appropriate output terminal on the front panel using a quick plug. Secure the ground clamp to the workpiece or welding table, ensuring good electrical contact.
3. TIG Torch Connection: Connect the TIG torch cable to the designated output terminal on the front panel. Ensure the gas hose from the torch is also connected to the machine's gas outlet.
4. Gas Cylinder Connection: Connect an argon gas cylinder to the gas inlet on the rear panel of the machine via a pressure regulator and gas hose. Ensure all gas connections are tight to prevent leaks.
5. Tungsten Electrode Installation: Install a tungsten electrode of the appropriate diameter (e.g., 2.5-3.2mm) into the TIG torch collet. Ensure it is sharpened correctly for TIG welding.

5. Operating Instructions

The TIG-300P offers precise control for various welding tasks. Always wear appropriate personal protective equipment (PPE) before operating.

1. Power On: Turn on the main power switch located on the machine. The digital display will illuminate.
2. Select Welding Mode: Use the function buttons on the front panel to select the desired welding mode (e.g., DC TIG, DC Pulse TIG).
3. Set Welding Parameters: Adjust the welding current (10-300A) using the control knob. For DC Pulse TIG, set the pulse frequency (0.5-200Hz) and other pulse parameters as needed for your application.
4. Gas Flow Adjustment: Open the valve on the argon gas cylinder and adjust the gas flow rate using the regulator. A typical flow rate for TIG welding is 10-15 liters per minute (L/min).
5. Arc Striking: Position the TIG torch over the workpiece. The "Dash-arc" technology ensures reliable, millisecond arc striking. Initiate the arc according to your torch's trigger mechanism.
6. Welding: Maintain a consistent arc length and travel speed. The machine is suitable for welding carbon steel and stainless steel.
7. Post-Flow: Allow the gas post-flow to cool the weld puddle and tungsten electrode, preventing oxidation.
8. Power Off: After welding, turn off the machine, close the gas cylinder valve, and bleed any remaining gas from the system.

6. Maintenance

Regular maintenance ensures the longevity and optimal performance of your JASIC TIG-300P.

• Cleaning: Regularly clean the exterior of the machine with a dry cloth. The dust-free closed air duct design minimizes internal dust accumulation, but periodic inspection of air vents is recommended.
• Fan Inspection: The intelligent fan system is designed for prolonged life. Ensure the fan intake and exhaust are clear of obstructions.
• Cable and Connection Check: Inspect all welding cables, gas hoses, and power cords for damage, cuts, or loose connections before each use. Replace any damaged components immediately.
• Tungsten Electrode Care: Properly grind and maintain tungsten electrodes for optimal arc stability and weld quality.
• Gas Regulator Check: Periodically check the gas regulator for proper function and leaks.

7. Troubleshooting

If you encounter issues with your TIG-300P, refer to the following common problems and solutions:

• No Power:
  - Check the main power supply and circuit breaker.
  - Ensure the power cable is securely connected to the machine and the outlet.
• No Arc:
  - Verify the ground clamp is securely attached to the workpiece.
  - Check the TIG torch connections and ensure the tungsten electrode is properly installed.
  - Confirm welding parameters are set correctly.
  - Ensure the gas flow is active (some machines require gas flow to initiate arc).
• Poor Weld Quality:
  - Check for proper gas flow and purity.
  - Ensure the tungsten electrode is clean and properly sharpened.
  - Adjust welding current, travel speed, and arc length.
  - Verify the material is clean and free of contaminants.
• Overheating:
  - Ensure the machine's ventilation openings are not blocked.
  - Allow the machine to cool down. The intelligent fan should manage heat effectively under normal conditions.
• Gas Leak:
  - Check all gas hose connections for tightness.
  - Inspect the gas hose for any damage.

For persistent issues, contact customer support.
