Can You TIG Weld Without Gas? Why Shielding Gas Is Non-Negotiable

ByWelderology Team

TIG welding depends on shielding gas to protect your weld from contamination. Unlike processes like stick or flux-core MIG, TIG doesn’t have built-in flux to keep oxygen and moisture out. Without gas, things start to go wrong almost immediately. Still, many beginners wonder if they can skip the gas to save a little money or…

AC vs DC Welding: Understanding the Current That Works for You

ByWelderology Team

Welding isn’t just about striking an arc and laying a bead—it’s also about understanding the kind of electrical current that powers your machine. That’s where the AC vs DC welding debate comes in. These two types of currents behave very differently, and choosing the right one can affect everything from arc stability to weld penetration….
