What are typical argon shielding gas flow rates?

Explanation:
Shielding gas flow rate in argon TIG welding must blanket the weld area without creating turbulence or wasting gas. For GTAW, a practical range is about 15 to 35 CFH. This mid-range covers common torch cups and joint configurations: around 15–20 CFH works well for small cups and lower amperage, while closer to 30–35 CFH helps with larger cups, higher amperage, longer arcs, or drafts. Rates outside this range can cause problems—too little shielding allows oxidation and porosity, while too much can blow away shielding, cause turbulence, and waste gas.
