1. Check the Cylinder
- Ensure the argon cylinder valve is closed.
- Check the regulator and gauges for damage.
- Make sure the sealing washer/O-ring is in good condition.
2. Attach the Regulator
- Connect the regulator to the argon cylinder valve.
- Tighten the nut using a spanner (do not over-tighten).
- Make sure the regulator is firmly fixed and straight
3. Connect the Gas Hose
- Attach the gas hose from the welding machine to the regulator outlet.
- Tighten the hose connection properly to prevent leaks.
4. Open the Cylinder Valve
- Slowly open the cylinder valve.
- The high-pressure gauge will show the cylinder pressure usually 150–200 bar).
5. Adjust Gas Flow
- Turn the flow adjustment knob on the regulator.
- Set the required flow on the flowmeter
Typical settings for welding:
- TIG Welding : 6–12 L/min
- MIG Welding : 10–18 L/min
6. Start Welding
- Press the torch trigger or start welding.
- Gas will flow through the regulator to protect the weld pool.
7. After Finishing
- Close the cylinder valve.
- Release the remaining gas pressure.
- Turn the regulator knob back to zero.
