Welding Glossary

The Ultimate Welding Glossary – Speak the Language of the Arc

At Arc-Zone, we know that welding has its own vocabulary—a mix of science, art, and a little bit of magic. That’s why we’ve put together the Arc-Zone Welding Glossary, your go-to guide for understanding the lingo that keeps the sparks flying.

Whether you’re a newbie trying to figure out what the heck “duty cycle” means or a seasoned pro looking to brush up on your terminology, this glossary is built for welders who want to know their stuff.


Why a Glossary?

Because knowledge is power. If you want to weld like a pro, you’ve got to talk like one. From arc length to Zirconium electrodes, we break it down in plain English (with a little welding grit) so you can focus on laying perfect beads—not scratching your head.


What’s Inside?

  • Clear Definitions: We skip the technical jargon and get straight to the point—no fluff, no filler.
  • Welding-Specific Terms: TIG, MIG, Stick, Plasma—it’s all here, no matter what type of welding you’re into.
  • Pro Tips Along the Way: We don’t just define; we drop knowledge bombs. Learn how to apply these terms in real-world welding scenarios.
