TIG welding stainless steel settings that deliver clean, repeatable results

When stainless turns gray, warps, or sugars, the culprit is almost always settings. TIG is unforgiving, and guessing costs time and rework. TIG Welding Secrets gives you precise, proven baselines for 304/316 across common gauges, so you can set the machine once and focus on the puddle. It lays out the exact TIG welding stainless steel settings top shops rely on for first-pass results.

Built from two decades of aerospace and sanitary work, it translates real shop data into simple dials: DCEN polarity, tungsten and cup selection, gas lens coverage, argon and purge flow, amperage by thickness, and pulse that controls heat without starving fusion. Expect pragmatic numbers such as 0.065 in stainless at 60–85 A with 1/16 in 2% lanthanated, #8–#12 gas lens at 18–22 CFH, 1–2 PPS with 35–45% background, and clear guidance on when to adjust for gaps, fit-up, or position. No fluff—just ranges, decision rules, and color targets for bright beads, flat reinforcement, and minimal distortion.

• Fast charts by gauge (0.035–0.125 in) for amperage, pulse, gas, and travel pace
• Back purging and trailing shield setups that stop sugar and meet inspection
• Troubleshooting by symptom: tint, undercut, porosity, arc wander, and fix-first steps
