21063003 - Arcair 3/8" x 12" DC Plain Copperclad Pointed Gouging Electrodes (50-Pack)

High-Efficiency Metal Removal with Arcair DC Copperclad Electrodes

The Arcair 3/8" x 12" DC Plain Copperclad Pointed Gouging Electrodes are engineered for industrial professionals requiring precision and power in metal removal applications. Manufactured from a high-density composite of carbon and graphite, these electrodes are designed to withstand the intense heat and current demands of Air Carbon Arc Cutting (CAC-A). The 21063003 model features a standard 3/8-inch diameter and a 12-inch length, making it a robust choice for heavy-duty fabrication and maintenance tasks.

A defining feature of these electrodes is the controlled copper coating. This conductive outer layer significantly improves electrical transfer efficiency, allowing the electrode to operate cooler than uncoated alternatives. This thermal management helps maintain the structural integrity of the rod, ensuring the diameter remains consistent at the arc point. For the operator, this translates to uniform groove widths and predictable performance, which is critical when preparing weld joints or removing defects.

These pointed plain electrodes are optimized for Direct Current Electrode Positive (DCEP) polarity. They excel in a variety of industrial applications, including the creation of U-grooves for weld joints, the removal of old or defective welds, and the gouging out of cracks in structural steel. They are also widely used in foundries for cleaning and repairing castings, as well as for rough machining operations. With an operating range of 450 to 600 Amps, these electrodes provide the necessary power density to blast away molten metal effectively when paired with a compressed air stream.

Supplied in a package of 50, these electrodes offer excellent value for high-volume workshops. Whether working on mild steel, stainless steel, copper alloys, or cast iron, the Arcair DC Plain Copperclad electrode delivers reliable, high-speed metal removal, reducing downtime and preparation costs in complex welding projects.
