AC vs DC for Aluminum TIG Welding: Key Insights and Best Practices Explained
The preferred current for TIG welding aluminum is AC (Alternating Current). AC removes the oxide layer, which helps create strong and clean welds. Although DC (Direct Current) can be used, it poses challenges for beginners. Using an AC-capable welding machine is essential for effective penetration and cleaning action. DC, or direct current, flows in one … Read more
