About this course

This course takes you from an empty bench to repeatable butt and fillet welds on mild steel, plus your first TIG puddle on thin sheet. You will learn the protective gear, machine setup, electrical settings, and torch and gun technique that working welders use every day, including how to read voltage and wire-feed-speed charts, dial in shielding gas, and judge a weld by its sound and bead profile. No coding or design software, just a welder, steel, and the habits that keep you safe and your welds sound.
