21983003 - Arcair 21983003 Copperclad DC Pointed Gouging Carbons 5/32 x 12 Inch

Technical Overview of Arcair DC Pointed Copperclad Electrodes

The Arcair 21983003 5/32" x 12" DC Pointed Copperclad® Gouging Electrodes represent the industry standard for air carbon arc metal removal. Engineered for precision and efficiency, these electrodes are manufactured from a high-grade composite of carbon and graphite. This specific formulation ensures rapid metal removal rates while maintaining arc stability. The defining feature of this product line is the controlled copper coating. This metallic layer serves a dual purpose: it significantly enhances electrical conductivity, reducing resistance heating within the electrode itself, and it helps maintain the structural integrity of the rod diameter during operation. This results in a cooler operating temperature, which minimizes the risk of electrode breakage and maximizes the linear inches of groove produced per electrode.

Designed for Direct Current Electrode Positive (DCEP) polarity, these pointed plain electrodes are optimized for a wide range of industrial applications. The 5/32-inch diameter is specifically rated for an operating amperage range of 300 to 400 amps. Operating within this parameter ensures the most effective ionization of the air stream and efficient melting of the base metal. The pointed tip geometry facilitates easy arc starting and allows for fine control when initiating grooves, making them particularly suitable for applications requiring high precision, such as removing weld defects or preparing U-grooves for subsequent welding passes.

In industrial maintenance and fabrication environments, the consistency of the Arcair Copperclad series is paramount. The manufacturing process ensures uniform density and coating thickness, which translates to predictable performance characteristics. Whether utilized for rough machining, removing hard surface material, or cleaning castings, these electrodes provide a stable arc column that works in concert with the compressed air stream to mechanically eject molten metal. The 12-inch length offers a balance between reach and manageability, fitting standard manual gouging torches. This pack of 50 ensures that operators have a sufficient supply for substantial gouging operations, reducing downtime associated with restocking consumables.
