Gas flow settings TIG: the field‑tested reference for clean, repeatable welds

Getting gas flow wrong costs you arc stability, surface finish, and money. Gas flow settings in TIG change with cup size, gas lens vs. standard collet body, tungsten diameter, stickout, AC vs. DC, joint type, position, and even shop drafts. TIG Welding Secrets distills all of this into clear, proven numbers and procedures so you can set flow once and weld with confidence.

Built by veteran fabricators and refined on stainless, aluminum, chromoly, and titanium, this guide gives you quick CFH/LPM ranges tied to cup #4–#12, 1/16–1/8 in. tungsten, and common amperage windows—plus when to deviate. You’ll get decision trees to fix porosity, sooting, and wandering arcs; purge setups for stainless/titanium with target flow and dwell; and checks to verify shielding quality without wasting argon. No fluff—just practical, repeatable methods aligned with industry best practice and verified on both inverter and transformer machines.

• Quick‑reference TIG gas flow charts by cup size, gas lens, material, position, and AC/DC, in CFH and L/min.
• Purge guidance that stops “sugaring”: dam placement, line volume, flow ramp, and vent strategy.
• Simple validation steps—arc start tells, bead edge color, and coupon tests—to lock in the right flow fast.

If you’re done guessing at “10–20 CFH” and chasing defects, TIG Welding Secrets gives you a tight, shop‑ready system for gas flow settings in TIG that improves arc focus, reduces rework, and cuts gas waste—day in, day out.
