TIG welding settings for stainless steel, nailed every time

Stainless punishes guesswork. Small shifts in amperage, gas flow, or pulse can mean perfect color—or sugar, distortion, and rework. Everything You NEED to Know About TIG Welding gives you proven tig welding settings for stainless steel by alloy and thickness, plus purge and heat-input controls that deliver bright, code-ready results.

Built by AWS-certified instructors and pressure-pipe fabricators, this field-tested guide translates real shop parameters into repeatable setups: DCEN, 2% lanthanated tungsten sizing and tip prep, gas lens coverage with 100% argon at 12–18 CFH (helium blends for thicker sections), start amps at ~1 amp per 0.001 in, and pulse baselines for thin gauge (1–2 Hz, 30–40% background, 35–50% on-time). You also get preflow/postflow timing, interpass temperature limits, purge flow and oxygen targets for sugar-free roots, plus quick troubleshooting by defect.

• Thickness-to-amperage tables from 0.035 in to 0.250 in.
• Dialed pulse presets to control heat tint and distortion.
• Purge recipes and gas lens/nozzle combos for mirror backsides.
