47203000 - Arcair DC Copperclad Pointed Carbon Gouging Electrode 1/4 x 12 Inch

Technical Overview of Arcair 47203000 Carbon Rods

The Arcair 47203000 is a premium-grade Air Carbon Arc Gouging Electrode designed for industrial metal removal applications. Measuring 1/4 inch (6.4 mm) in diameter and 12 inches (305 mm) in length, this rod is engineered to provide consistent arc stability and efficient material removal rates. The electrode is manufactured from a composite of carbon and graphite, formulated to withstand the high current densities required for the air carbon arc process.

This specific SKU features a DC Copperclad construction. The copper coating serves a dual purpose: it significantly enhances electrical conductivity, reducing resistance heating along the length of the rod, and it helps maintain the rod's structural integrity during operation. The "Pointed" geometry is standard for manual operations, facilitating immediate arc initiation and allowing the operator to control groove width and depth with precision. The rod is designed for use with Direct Current Electrode Positive (DCEP) polarity, typically operating within an amperage range of 300 to 400 Amps for the 1/4-inch diameter size.

In industrial MRO settings, the Arcair 47203000 is utilized for back-gouging welds, removing defective welds, and preparing plate edges for welding. The high-density graphite mix ensures that the rod is consumed evenly, preventing "penciling" or irregular burn-off that can disrupt the gouging process. This product is compatible with standard manual gouging torches (such as the Arcair K4000) and requires a compressed air supply (typically 80-100 psi) to effectively blow molten metal away from the groove.
