How to Use This Calculator
- Enter the nozzle diameter in inches for your MIG or TIG torch.
- Select the weld type (MIG, TIG, FCAW, etc.) and the wind condition at the weld location.
- Choose the base material type — stainless, aluminum, and reactive metals need higher flow rates.
- Read Recommended Flow Rate (CFH) as the target setting for your regulator.
- Keep the rate between Minimum Flow and Maximum Flow to ensure proper shielding without turbulence.
- Adjust upward in drafty or outdoor conditions and verify coverage by observing a clean, porosity-free bead.
