TIG welding settings for stainless steel, made simple and repeatable

Stainless is unforgiving. Get TIG welding settings for stainless steel wrong and you’ll chase warping, sugar, and heat tint. Get them right and you’ll lay bright, sanitary beads with tight heat control and minimal rework. TIG Welding Secrets distills the exact parameters that pros use—so you can set up fast, weld clean, and move on.

Built by career TIG welders and instructors, this guide gives you precise starting points by alloy and thickness: DCEN polarity, amperage windows, pulse recipes for thin sheet, tungsten and filler selection, gas lens and cup sizing, argon flow rates, and back-purging best practices. It also covers travel speed targets, arc length, torch angle, and cooling strategy to control distortion and preserve corrosion resistance—plus troubleshooting for color, porosity, and crater cracking.

• Thickness-based amperage and pulse tables for 304/316 from thin gauge to plate.
• Shielding gas and purge setups (cup sizes, gas lens, 12–25 CFH ranges) for chrome-bright results.
• Heat input control: arc length, tack spacing, and sequencing to keep panels flat.
