20033003 - Arcair 3/16" x 12" AC Pointed Copperclad Gouging Carbons (50 Pack)

High-Performance AC Gouging Electrodes

The Arcair 3/16" x 12" AC Pointed Copperclad Arc Gouging Electrode is a specialized consumable engineered to deliver superior metal removal performance when using alternating current (AC) power supplies. Unlike standard direct current (DC) electrodes, these rods are formulated with a precise blend of carbon and graphite, enhanced with rare earth materials. This unique chemical composition is critical for stabilizing the arc in AC applications, preventing the arc instability often associated with alternating current polarity. The result is a smooth, consistent gouging action that rivals DC performance.

Each electrode features a high-quality copper cladding. This copper coating serves multiple functions: it significantly improves electrical conductivity, allowing for efficient energy transfer from the torch to the workpiece, and it helps maintain cooler operating temperatures along the length of the rod. By reducing resistance heating, the electrode maintains its structural integrity longer, ensuring uniform consumption and reducing the likelihood of tapering or "penciling" that can degrade groove quality. The 3/16-inch diameter is ideal for medium-duty gouging tasks, offering a balance between metal removal rate and precision control.

These electrodes are designed specifically for the air carbon-arc process, a method widely used in foundries, fabrication shops, and maintenance departments for removing old welds, gouging out cracks, and preparing plate edges for welding. The pointed tip design facilitates easy arc starting and allows the operator to establish a clean groove immediately. With a length of 12 inches, these rods fit standard air carbon-arc torches and provide ample material for extended use before requiring a changeout. Packaged in cartons of 50, the Arcair 20033003 ensures you have a reliable supply of high-performance consumables ready for demanding industrial environments.

Whether you are working on mild steel, stainless steel, or other alloys compatible with the carbon-arc process, these AC-specific electrodes provide the stability and efficiency needed to maximize productivity. The addition of rare earth stabilizers marks a significant advancement in AC gouging technology, making these electrodes the preferred choice for operators restricted to or preferring AC power sources.
