Proper purging is critical for clean, high-quality TIG welds—especially on stainless steel and other reactive materials.
The How to Purge TIG Welds (PDF) walks you through the fundamentals of purge setup, gas coverage, and best practices to prevent oxidation, contamination, and sugaring on the backside of your weld.
What you’ll learn:
- Why purging is essential for weld integrity and corrosion resistance
- How to properly set up a purge system
- Recommended gas flow rates and purge techniques
- Tips to avoid common mistakes like leaks and over-purging
Clean purge = clean weld. Get the setup right before you strike an arc.
