OVERVIEW

Power Through the Toughest Gouging Jobs

When you are staring down a massive repair job or need to hog out a serious amount of steel, standard carbons just won't cut it. You need the Arcair 47143000 7/8 x 12 Carbon Rod. These are the heavy hitters of the gouging world, built for welders who operate in the extreme ranges of amperage and heat. With a 7/8-inch diameter, this rod is designed for use with heavy-duty foundry torches or high-capacity gouging equipment, allowing you to remove metal faster and cleaner than ever before.

The secret to Arcair's performance lies in the quality of the rod. These copperclad pointed carbons strike easy and burn smooth. The copper coating isn't just for looks; it keeps the rod running cool and ensures the current transfers efficiently from your torch jaws to the arc. This means less resistance, a more stable arc, and a groove that is consistent from the start of the pass to the end. No more sputtering or wandering arcs that leave a jagged mess you have to grind out later.

These rods are perfect for:

  • Back-gouging heavy plate welds: Ensure 100% penetration on thick structural steel.
  • Foundry work: Quickly remove risers, fins, and defects from large castings.
  • Equipment repair: Cut out cracks in heavy earthmoving equipment buckets and frames.

Using the air carbon arc process with these rods is efficient and cost-effective. You get a clean, bright U-groove that is often ready for welding immediately with little to no additional cleanup. Just hook up your air supply, crank up the amps (DCEP), and let the Arcair 47143000 do the hard work. When time is money and the metal is thick, trust the brand that invented the process to help you get the job done right.

FAQ

For a 7/8 inch (22.2 mm) carbon rod, the typical operating current range is approximately 1200 to 1600 Amps. Always consult your specific torch and power source manual to ensure they can handle this load.

These copperclad pointed rods are designed for use with Direct Current Electrode Positive (DCEP), also known as Reverse Polarity.

No, a standard K4000 torch typically accepts round carbons up to 1/2 inch. A 7/8 inch rod requires a heavy-duty foundry torch or a specific high-amperage gouging torch designed for large diameter electrodes.

The copper coating improves electrical conductivity, helps keep the electrode cool during operation, and maintains the rod's diameter for consistent feeding and arc stability.

Standard air carbon arc gouging typically requires compressed air between 80 and 100 psi (5.5 - 7 bar) and sufficient flow (cfm) to effectively blow away the molten metal created by the large arc.

No, these specific copperclad pointed rods are designed for DC applications. For AC power sources, specific AC-grade pointed carbons (often without copper or with special additives) are required.

This specific item is listed as a single unit (1 Per Ea), though they are often bulk packaged in boxes for industrial use. Please verify the quantity needed for your project.

They are effective on carbon steel, stainless steel, cast iron, and many copper alloys. The process is versatile for removing metal from almost any conductive workpiece.
