35099003 - Arcair 3/8 x 5/32 Flat Gouging Carbons 50 Pack

Arcair Copperclad Professional Flat Gouging Carbons

Maximize your gouging efficiency with Arcair's 3/8" x 5/32" x 12" DC Flat Copperclad Electrodes. As the industry leader in air carbon arc gouging technology, Arcair produces consumables that define the standard for performance and reliability. These flat electrodes are specifically designed for applications where a round groove is undesirable. By utilizing a rectangular profile, operators can effectively plane off metal layers, scarf billets, and remove weld reinforcements flush with the base metal, significantly reducing the time and labor required for secondary finishing processes.

Superior Conductivity and Performance

The core of the Arcair 35099003 electrode is a precise blend of carbon and graphite, formulated to withstand the intense heat and physical demands of heavy-duty gouging. The uniform copper coating is applied using a controlled process that ensures optimal thickness and adhesion. This copper layer improves the electrical characteristics of the rod, enabling a stable arc and efficient metal melting. Furthermore, the coating acts as a shield, reducing the erosion of the electrode's sides and helping to maintain the 3/8-inch width throughout the gouging pass. This results in a uniform groove width and a predictable metal removal profile.

Operational Specifications

These electrodes are optimized for use with DC welding power sources set to DCEP (Reverse Polarity). The recommended operating amperage range is typically between 250 and 450 amps, depending on the specific depth of cut and travel speed required. To achieve the best results, these electrodes should be used with a suitable air carbon arc torch equipped with a head or jaw assembly capable of gripping flat electrodes. The high-velocity air stream from the torch effectively blows away the molten metal, leaving a clean surface that is often ready for re-welding with minimal preparation. Each box contains 50 electrodes, ensuring you have the inventory needed for substantial projects.
