47143000 - Arcair 7/8 x 12 DC Pointed Gouging Carbons

Heavy-Duty Metal Removal with Arcair Precision

The Arcair 47143000 7/8 x 12 Carbon Rod represents the upper echelon of air carbon arc gouging consumables, designed specifically for heavy industrial environments such as foundries, shipyards, and large-scale steel fabrication facilities. Manufactured by the industry leader in gouging technology, these rods are engineered to deliver maximum metal removal rates with exceptional arc stability. The 7/8-inch diameter is substantial, requiring high-amperage power sources, making it suitable for deep gouging, severing heavy sections, and rapid material excavation.

Each rod features a precise blend of carbon and graphite, formulated to resist breakage and thermal shock while maintaining a consistent burn rate. The exterior is coated with a controlled layer of copper, which serves multiple critical functions: it enhances electrical conductivity, improves arc starting characteristics, and helps maintain the rod's structural integrity during operation. This copper cladding also ensures that the electrode diameter remains uniform, preventing jamming or inconsistent feeding in manual or mechanized torches.

Utilizing Direct Current Electrode Positive (DCEP) polarity, these pointed rods focus the arc energy intensely, melting the base metal rapidly while a jet of compressed air blows the molten material away. This process is far more efficient than mechanical grinding for removing large volumes of metal, such as excavating cracks in heavy castings or preparing thick plates for welding. The 12-inch length provides a good balance between operational duration and handling, minimizing downtime for rod changes in manual operations.

Professionals rely on Arcair because consistency matters in critical gouging applications. Whether you are back-gouging a full-penetration weld on a pressure vessel or cleaning up casting defects, the 47143000 rod delivers the performance required to keep production schedules on track. Its ability to produce clean, smooth U-grooves reduces the need for secondary grinding, streamlining the workflow from removal to re-welding.
