21043003 - Arcair 1/4" x 12" DC Pointed Copperclad Gouging Electrodes (50-Pack)

High-Efficiency Metal Removal with Arcair Copperclad Electrodes

The Arcair 21043003 1/4" x 12" DC Pointed Copperclad Gouging Electrodes represent the industry standard for air carbon-arc cutting and gouging (CAC-A). Designed for professional fabrication and maintenance environments, these electrodes are engineered to remove metal efficiently while generating minimal heat input into the base material. The "Copperclad" designation refers to a precise copper coating that surrounds the high-grade carbon-graphite core. This coating serves two critical functions: it significantly enhances electrical conductivity for a stable arc, and it helps maintain the electrode's structural integrity during operation, ensuring the diameter remains consistent at the arc point.

These DC plain pointed electrodes are specifically formulated for use with Direct Current Electrode Positive (DCEP) polarity. With a diameter of 1/4 inch and a length of 12 inches, they are optimized for an operating amperage range of 300 to 400 amps. This range provides the necessary energy density to melt the base metal rapidly while a jet of compressed air blows the molten material away. The result is a clean, smooth U-groove that often requires little to no secondary grinding before welding.

Industrial applications for these electrodes are vast. They are the tool of choice for back-gouging weld seams to ensure complete joint penetration. Maintenance teams rely on them for removing old welds, gouging out cracks in structural steel, and cleaning up castings in foundries. The pointed tip allows for easy arc starting and precise control at the beginning of a groove. Whether you are performing rough machining or removing hard surface material, the Arcair 21043003 electrodes deliver consistent performance and durability.

Packaged in a convenient carton of 50, these electrodes are a staple for any heavy industrial welding operation. The consistent quality of Arcair's manufacturing ensures that each rod performs identically, reducing downtime associated with arc instability or uneven burning. By maintaining a cooler operation through superior conductivity, these rods also help prolong the life of the gouging torch.
