22063003 - Arcair 3/8 x 12 DC Pointed Copperclad Gouging Electrodes (50-Pack)

Arcair 22063003 3/8" x 12" DC Pointed Copperclad Gouging Electrodes

The Arcair 22063003 DC Pointed Copperclad Gouging Electrodes represent the industry standard for air carbon-arc metal removal. Designed for use with Direct Current (DC) power sources operating on DCEP (Reverse Polarity), these electrodes are engineered to deliver efficient, consistent performance in demanding industrial environments. Each carton contains 50 high-grade carbon graphite rods, measuring 3/8 inch in diameter and 12 inches in length, specifically formulated to withstand the high currents required for effective gouging.

A key feature of these electrodes is the controlled copper coating. This copper cladding serves a dual purpose: it significantly improves electrical conductivity, allowing the electrode to run cooler and more efficiently, and it helps maintain the structural integrity of the rod at the point of the arc. By preventing the diameter from degrading prematurely, the electrode produces a consistent, uniform groove width throughout the gouging process. This is critical for applications requiring precision, such as weld preparation or defect removal, where the geometry of the groove impacts subsequent welding operations.

These electrodes are rated for an amperage capacity of 450 to 600 Amps. Operating within this range ensures optimal metal removal rates while maximizing the lifespan of the consumable. The air carbon-arc process utilizes the electric arc to melt the base metal while a high-velocity jet of compressed air blows the molten metal away. The Arcair 22063003 rods are formulated to facilitate this process with excellent arc stability and reduced resistance. They are suitable for a wide variety of metals, including carbon steel, stainless steel, and copper alloys, making them a versatile tool for fabrication shops, maintenance departments, and heavy industrial facilities.

Proper storage and handling are recommended to maintain performance. Electrodes should be kept dry to prevent moisture absorption, which can lead to splintering or erratic arc behavior. In the event of moisture exposure, baking instructions should be followed as per manufacturer guidelines. Safety precautions, including appropriate fume extraction and personal protective equipment (PPE), are essential when performing carbon arc gouging due to the generation of fumes and noise.
