47243000 - Arcair 1-1/2 Inch x 12 Inch Heavy Duty Gouging Carbon

Technical Overview

The Arcair 47243000 1-1/2 x 12 Carbon Rod is a specialized consumable designed for the most demanding air carbon arc gouging (CAC-A) applications. Engineered with a substantial 1-1/2 inch diameter, this electrode is intended for heavy industrial environments such as foundries, shipyards, and massive steel fabrication facilities where rapid metal removal is critical. The rod is manufactured from a precise blend of carbon and graphite, compacted to a high density to ensure structural integrity under the extreme heat and pressure of high-amperage arcs.

A key feature of this electrode is its copper coating. This conductive layer serves multiple technical purposes: it significantly enhances electrical conductivity, allowing for efficient energy transfer from the power source to the workpiece, and it helps maintain the rod's diameter during operation by reducing radiant heat erosion. The 12-inch length offers a standard form factor that balances consumable life with torch maneuverability. This rod is capable of sustaining the high current densities required to melt and blow away large volumes of base metal, making it an essential tool for removing defects in large castings, preparing heavy plate edges, and washing pads.

Operators utilizing the Arcair 47243000 can expect consistent performance characteristics, including a stable arc and uniform burn-off rate. This consistency is vital for automated or semi-automated gouging processes where precision and predictability are required to maintain production schedules. The rod is compatible with standard DCEP (Direct Current Electrode Positive) polarity setups and requires a sufficient compressed air supply to effectively clear the molten pool.
