EXCU00000000620T00 - Exocor ERCu Deoxidized Copper TIG Filler Rod .062"

Weld Copper with Confidence Using Exocor ERCu Rods

If you have ever tried welding copper, you know it behaves differently than steel or stainless. It sucks the heat away from your puddle faster than you can blink. That’s why having the right filler metal is absolutely essential. The Exocor ERCu Deoxidized Copper TIG Rod is designed to make your life easier when fabricating copper components. Whether you are working on custom copper stills, artistic sculptures, or heavy-duty electrical bus bars, this rod gives you the smooth flow and clean deposit you need to produce professional-looking results.

This 1/16" (.062") rod is the perfect size for fine detail work or bridging small gaps. Because it is "deoxidized," it contains special elements that fight off the bubbles and porosity that often plague copper welds. This means you get a solid, dense bead that doesn't look like a sponge when you cut into it. The color match is also spot-on; once you polish your weld, it blends seamlessly with the base copper, making it ideal for architectural and decorative work where aesthetics are just as important as strength.

Tips for Success: Welding copper requires heat—lots of it. Even with this high-quality rod, you may need to preheat your workpiece if it's thicker than 1/8 inch to ensure the puddle flows out nicely. We recommend using 100% Argon for thinner stuff, but if you are tackling thick sections, switching to a Helium/Argon mix can give you that extra punch of heat. Keep your arc tight, move quickly, and let the Exocor ERCu rod do the work. It is also a handy rod to keep in your shop for those odd jobs where you need to join a piece of copper to a steel bracket. With Exocor, you are getting a consistent, clean-burning rod that helps you master one of the trickier metals in the welding world.
