21053003 - Arcair 5/16 DC Copperclad Pointed Gouging Carbons (50 Pack)

Precision Metal Removal with Arcair DC Pointed Copperclad Electrodes

The Arcair 21053003 5/16" x 12" DC Pointed Copperclad Gouging Electrode is a premium consumable designed for the rigorous demands of the Air Carbon Arc Gouging (CAC-A) process. Engineered by the industry leader in gouging technology, these electrodes are manufactured from a high-density composite of carbon and graphite. This specific formulation ensures superior metal removal rates while maintaining arc stability, making them an essential tool for industrial fabrication, shipbuilding, and heavy equipment maintenance.

A defining feature of this electrode is its controlled copper coating. This conductive outer layer serves a dual purpose: it significantly enhances electrical conductivity, allowing for more efficient energy transfer from the power source to the workpiece, and it helps dissipate heat, keeping the electrode cooler during operation. This results in a more uniform burn-off rate and helps maintain the electrode's 5/16-inch diameter at the arc point, ensuring consistent groove geometry. The pointed design is particularly effective for initiating grooves and accessing tight spaces, providing the operator with excellent control over the gouging profile.

These electrodes are optimized for use with Direct Current Electrode Positive (DCEP) polarity. Operating within a recommended amperage range of 350 to 450 amps, they deliver the thermal intensity required to melt base metals rapidly while a jet of compressed air blows the molten material away. This process is highly effective for a variety of applications, including creating U-grooves for weld joint preparation, removing defective welds, gouging out cracks for repair, and cleaning castings in foundry environments. The 12-inch length offers a balance between reach and manageability, reducing the frequency of electrode changes during extended gouging sessions.

In industrial settings where downtime equates to lost revenue, the reliability of Arcair Copperclad electrodes ensures continuous throughput. Whether used for rough machining or removing hard surface materials, these electrodes provide a clean, bright surface ready for subsequent welding or inspection. This 50-count carton ensures that workshops are well-stocked for high-volume projects, delivering professional-grade performance that meets the stringent standards of modern metalworking.
