24124003C - Arcair CutSkill 3/4 x 17 DC Copper Coated Gouging Electrodes (100 Pack)

Technical Precision in Air Carbon Arc Gouging

Arcair's CutSkill DCCC (Direct Current Copper Coated) Gouging Carbons, specifically the 24124003C model, represent a standard of excellence in the field of air carbon arc gouging. Measuring 3/4 inch in diameter and 17 inches in length, these electrodes are formulated from a precise blend of carbon and graphite. This composition is essential for creating the intense arc heat required to melt base metals effectively while the stream of compressed air physically ejects the molten material from the groove. This process is widely recognized for its speed and versatility on materials including carbon steel, stainless steel, and various alloys.

The copper coating on these DCCC electrodes serves multiple technical functions. Primarily, it enhances the electrical transfer efficiency from the torch jaws to the carbon tip. In high-amperage applications typical for a 3/4-inch rod, resistance heating within the electrode itself can be a limiting factor; the copper layer mitigates this, keeping the electrode cooler along its length and focusing the energy at the arc. Additionally, the coating provides structural integrity, reducing the likelihood of breakage during handling or operation. The result is a stable, focused arc that operators can control easily to achieve the desired groove depth and width.

These electrodes are designed for use with Direct Current Electrode Positive (DCEP) polarity. This polarity setup ensures that the majority of the heat is generated at the workpiece, maximizing melting efficiency. The 17-inch length is particularly advantageous for deep gouging or long continuous passes, reducing the interruption caused by stub loss and electrode replacement. For welders and fabricators, this translates to higher duty cycles and faster project completion times.

Applications for the 3/4-inch CutSkill carbon are typically found in heavy industry sectors. They are frequently used for back-gouging weld seams to sound metal, removing temporary lifting lugs, and dismantling steel structures. The air carbon arc process is often preferred over oxy-fuel cutting for defect removal because it does not rely on the oxidation of the metal, making it suitable for non-ferrous metals as well. With 100 pieces per box, this package ensures that your facility is stocked for extensive gouging campaigns, delivering consistent performance from the first rod to the last.
