1. تعارف
This manual provides essential instructions for the safe and effective use of the VICTOR GRF400-580 Flowmeter Regulator. This compact and economical regulator is designed for light-duty applications involving Argon, Argon/CO2 mixtures, and Helium gases, commonly used in TIG and MIG welding processes.
مناسب کام اور حفاظت کو یقینی بنانے کے لیے براہ کرم انسٹالیشن اور آپریشن سے پہلے اس دستی کو اچھی طرح پڑھیں۔
2. حفاظتی معلومات
WARNING: Improper use of gas regulators can lead to serious injury or death. Always follow safety guidelines.
- Ensure the regulator is compatible with the gas cylinder and application.
- Never use oil or grease on oxygen or other oxidizing gas equipment.
- Always secure gas cylinders to prevent tipping.
- Open cylinder valves slowly.
- Check for leaks using a suitable leak detection solution.
- مناسب ذاتی حفاظتی سامان (پی پی ای) پہنیں۔
- Do not exceed the maximum inlet pressure of 3000 psig.
3. مصنوعات کے اجزاء
The VICTOR GRF400-580 Flowmeter Regulator consists of the following key components:
- CGA-580 Inlet Connection: For connecting to Argon, Argon/CO2, and Helium gas cylinders.
- پریشر گیج: Displays the cylinder's internal pressure (up to 3000 psig).
- Flowmeter Tube: High-impact Lexan tube with scales for Argon, Helium, and Carbon Dioxide, indicating gas flow in SCFH.
- Precision Needle Valve: For fine adjustment of gas flow.
- آؤٹ لیٹ کنکشن: Typically a 5/8"-18 female connector for hose attachment.

4. سیٹ اپ ہدایات
- Prepare the Cylinder: Ensure the gas cylinder is secured upright to a wall or cylinder cart. Remove the cylinder valve cap.
- کنکشن کا معائنہ کریں: Check the regulator's CGA-580 inlet connection and the cylinder valve for any damage, dirt, or debris. Ensure the sealing surfaces are clean.
- Connect Regulator: Thread the regulator's CGA-580 inlet connection onto the cylinder valve. Hand-tighten, then use an appropriate wrench to tighten securely. Do not overtighten.
- کنیکٹ ہوز: Attach your welding hose to the regulator's outlet connection (typically 5/8"-18 female). Tighten securely.
- Open Cylinder Valve: Slowly open the cylinder valve counter-clockwise until fully open. The pressure gauge on the regulator should indicate the cylinder's internal pressure.
- لیک کے لیے چیک کریں: Apply a leak detection solution (e.g., soapy water) to all connections. Bubbles indicate a leak. If a leak is detected, close the cylinder valve, relieve pressure, and re-tighten connections. Repeat until no leaks are present.
5. آپریٹنگ ہدایات
Once the regulator is securely installed and leak-checked, follow these steps for operation:
- بہاؤ کی شرح مقرر کریں: Ensure the precision needle valve on the flowmeter is closed (turned clockwise). Slowly open the needle valve counter-clockwise until the ball in the flowmeter tube rises to the desired flow rate (SCFH). Read the flow rate at the center of the ball.
- Gas Selection: The flowmeter tube has scales for Argon, Helium, and Carbon Dioxide. Ensure you are reading the correct scale for the gas being used.
- Argon: 5 - 50 SCFH
- Helium: 20 - 150 SCFH
- Carbon Dioxide: 5 - 40 SCFH (20% duty cycle)
- مانیٹر پریشر: Periodically check the pressure gauge to monitor the remaining gas in the cylinder.
- بند کریں: When finished, close the cylinder valve first. Allow the gas in the regulator and hose to bleed out until the flowmeter ball drops and the pressure gauge reads zero. Then, close the precision needle valve on the flowmeter.

6 دیکھ بھال
Regular maintenance ensures the longevity and safe operation of your flowmeter regulator.
- معائنہ: Periodically inspect the regulator for any signs of damage, wear, or leaks. Check the flowmeter tube for cracks or cloudiness.
- صفائی: Keep the regulator clean and free of dust, dirt, and oil. Use a clean, dry cloth. Do not use solvents or abrasive cleaners.
- ذخیرہ: When not in use, store the regulator in a clean, dry environment, protected from physical damage and extreme temperatures.
