OVERVIEW

Heavy-Duty Metal Removal with Arcair 3/4" Carbon Rods

The Arcair 47-123-000 3/4" x 12" DC Copperclad Pointed Carbon Rods are engineered for the most demanding industrial metal removal applications. Designed for use with the air carbon-arc gouging process, these large-diameter electrodes are capable of removing significant amounts of metal quickly and efficiently. They are an essential consumable for heavy fabrication shops, shipyards, foundries, and maintenance operations involving heavy earthmoving equipment. By combining an electric arc to melt the metal and a jet of compressed air to blow it away, these rods provide a fast and cost-effective method for gouging, grooving, and severing.

Manufactured from a high-density composite of carbon and graphite, Arcair rods are known for their consistency and performance. The 3/4-inch diameter is specifically suited for high-amperage applications where deep, wide grooves are required in a single pass. This makes them ideal for back-gouging heavy plate welds, removing massive defects in castings, or dismantling large steel structures. The precise formulation ensures that the rods consume evenly, reducing waste and providing the operator with excellent control over the groove dimensions.

A key feature of the 47-123-000 series is the controlled copper coating. This conductive outer layer improves arc stability and reduces electrical resistance, allowing the rod to run cooler and more efficiently than plain carbon rods. This coating also helps maintain the rod's diameter during operation, ensuring a uniform groove width from start to finish. Whether you are preparing J-grooves or U-grooves for welding joints or removing hardfacing from wear parts, these Arcair electrodes deliver the reliability professionals trust.

Safety and efficiency are paramount in heavy industrial environments. Using genuine Arcair consumables ensures compatibility with high-capacity gouging torches and power sources. These rods are designed to operate on Direct Current Electrode Positive (DCEP), providing the necessary heat input to melt base metals such as carbon steel, stainless steel, and various alloys effectively. Invest in Arcair 3/4" rods for your toughest gouging tasks and experience the difference in speed and quality.

FAQ

For 3/4-inch diameter DC copperclad pointed rods, the recommended current range is typically between 800 and 1200 Amps. Always consult the specific chart for your power source and application.

These rods are designed for Direct Current Electrode Positive (DCEP), also known as Reverse Polarity. This setting ensures proper heat distribution for efficient metal removal.

Most standard manual torches (like the K4000) are rated for rods up to 1/2 inch. A 3/4-inch rod requires a heavy-duty torch, such as the Tri-Arc foundry torch or specific automated equipment, to accommodate the diameter and amperage.

The copper coating improves electrical conductivity, helps keep the rod cool by reducing resistance, and maintains the rod's diameter for a more uniform groove width.

These DC rods are suitable for gouging carbon steel, stainless steel, cast iron, and various copper alloys. They are not typically used for aluminum (which often uses AC).

They should be stored in a cool, dry place. While they are not as sensitive to moisture as low-hydrogen welding electrodes, keeping them dry prevents potential coating oxidation or performance issues.

A 3/4" rod is used for removing large amounts of metal quickly, such as in foundries for removing risers, or in heavy fabrication for back-gouging thick plates.

Yes, the Air Carbon Arc Gouging process requires a supply of compressed air (typically 80-100 psi) to blow away the molten metal created by the arc.
