Gas flow settings TIG — dial in shielding gas like a pro

Most TIG defects start with gas. Dialing amperage won’t fix porosity, soot, or a dull etch if your shielding is wrong. Gas flow settings TIG are driven by cup size, gas lens, torch angle, joint type, and shop drafts—not guesswork. Everything You NEED to Know About TIG Welding translates all of that into repeatable numbers and a simple setup sequence. You get proven CFH/LPM baselines for steel, stainless, aluminum, and titanium; open air vs enclosed work; fillets, lap joints, and inside corners; cups #4–#12, standard and gas lens. Developed and validated by certified welders under real production conditions, it delivers code-ready practices without the noise.

Use it to lock in a laminar shield, cut argon waste, and stabilize arc starts. Learn how to set pre-flow and post-flow, match flow to travel speed, and tune purge for stainless and reactive alloys. Visual coverage checks, leak-finding steps, and a fast troubleshooting tree take you from pinholes and sugaring to clean, bright beads with less rework. Fewer variables, faster setups, consistent results—on benches, in booths, or in the field.

• Clear CFH/LPM tables by cup ID, process, position, and gas lens.
• Baseline formula plus environment factors for wind and drafts.
• Printable setup cards and WPS-style checklists for repeatability.
