TIG setup for stainless that produces clean, corrosion‑resistant welds

When stainless demands zero sugar, tight heat control, and repeatable quality, guesswork costs time and rework. “Everything You NEED to Know About TIG Welding” breaks down a proven tig setup for stainless—DCEN with 100% argon, gas lens with #8–#12 cups, 1/16–3/32 in. 2% lanthanated tungsten, and practical amps-by-thickness starting points—then shows how to adjust with intent, not trial-and-error.

Built from AWS-aligned procedures and thousands of shop hours, this guide gives stainless-specific prep, purge, and technique: proper joint cleaning, 308L/309L filler selection, arc-length discipline, pulse ranges for heat tint control, and distortion management. You’ll get printable setup charts, troubleshooting flowmaps, and visual cues to eliminate porosity, wandering arc, and overheated, discolored beads—so welds pass inspection and last in service.

• Exact settings by thickness: amps, tungsten size, cup, gas flow (CFH), and travel baselines.
• Repeatable controls: fit-up, backpurge strategy, torch angle, filler timing, and cooldown.
• Fast diagnostics: read color, bead profile, and arc sound to correct defects on the fly.
