KP3801-3/16 - Lincoln CarbonElite 3/16" Hollow Gouging Carbons (50 Pack)

Precision Gouging for Professional Welders

Lincoln Electric's KP3801-3/16 CarbonElite Hollow Gouging Electrodes are built to handle the toughest metal removal jobs in the industry. For welders familiar with the Air Carbon Arc (CAC-A) process, the difference in quality between generic carbons and the CarbonElite series is immediately noticeable. These 3/16-inch x 12-inch electrodes are crafted with a high-density synthetic graphite core that resists thermal shock and mechanical stress. The defining feature of this specific SKU is its hollow core. By removing the center of the graphite rod, the arc plasma is concentrated on the rim, and the air stream is able to evacuate molten metal more efficiently. This translates directly to higher travel speeds and a more aggressive cutting action without sacrificing control.

The heavy copper coating on these electrodes is uniform and robust, ensuring excellent electrical contact with the torch jaws. This minimizes arcing at the contact point and prevents the rod from overheating prematurely. When back-gouging a root pass or excavating a crack in a heavy casting, arc stability is crucial to avoid introducing new defects or carbon inclusions. The CarbonElite formulation provides a smooth, hissing arc that melts base material consistently, allowing the compressed air jet to blow it away cleanly. The result is a bright, clean groove that is often ready for welding with minimal grinding.

These electrodes are optimized for DC operation (DCEP) and are compatible with standard manual and automatic gouging torches. The 3/16-inch diameter is versatile enough for medium-duty gouging on plate and pipe, offering a balance between groove width and depth control. With 50 electrodes per carton, the KP3801-3/16 pack ensures you have the consumables needed to keep the work flowing. Whether you are working in maintenance repair, pressure vessel fabrication, or mining equipment overhaul, these hollow carbons provide the reliability and performance professional welders expect from the Lincoln Electric brand.

Technical Advantages:

• Optimized Arc Physics: Hollow core concentrates the arc for rapid metal removal.
• Superior Conductivity: Copper coating ensures efficient current transfer and cooler operation.
• Consistent Quality: Manufactured to strict tolerances to prevent jamming and ensure uniform burn-off.
