TIG welder settings for stainless steel: precise, repeatable results

If you want consistent color, penetration, and distortion control, the exact TIG welder settings for stainless steel matter. Most advice is vague. Everything You NEED to Know About TIG Welding delivers precise, repeatable settings by alloy and thickness: DCEN polarity, amperage windows, pulse ratios, gas flow, tungsten and cup selection, and travel-speed targets — all validated in shop trials and QA standards. Expect stack-of-dimes beads with minimal heat tint and no root sugaring.

Written by CWIs and production welders with 15+ years across sanitary, aerospace, and fab, it distills WPS-level detail into simple dials you can set today. Reduce rework and hit spec faster — from 0.040 in sheet to 1/4 in plate. Includes troubleshooting for porosity, warping, and chromium carbide precipitation, plus fit-up and purge best practices.

• Starting points: amperage by thickness, pulse (peak/background 30–50%, 1–2 Hz), gas flow 15–20 CFH, postflow timing.
• Consumables matched: 2% lanthanated tungsten, gas lens #8–12, 308L/316L fillers by base metal.
• Process control: DCEN, 10–15° torch angle, tight arc length, interpass temp limits for color control.
