When it comes to removing metal fast, professional welders trust Arcair. The Arcair 3/8" x 12" DC Plain Copperclad Gouging Electrodes (Part Number 21063003) are the industry standard for air carbon arc gouging. If you need to blow out a bad weld, prep a thick plate for a full-penetration joint, or wash away a crack in a casting, these carbons are built to handle the job. This pack contains 50 pointed electrodes, ensuring you have plenty of consumables on hand for those long shifts or big tear-down projects.
The secret to their performance lies in the copper cladding. Unlike bare carbons that can overheat and crumble, the copper coating on these Arcair rods helps carry the massive current—between 450 and 600 amps—smoothly to the tip. This keeps the rod cooler along its length and focuses the energy right where you need it: at the arc. The result is a stable, fierce arc that melts metal instantly, while the air jet from your gouging torch blows it away cleanly. The pointed tip allows for easy arc starting and fine control when beginning a groove.
These electrodes are designed for use with DC power sources on Reverse Polarity (DCEP). They are incredibly versatile and can be used on a wide range of base metals, including carbon steel, stainless steel, and ductile iron. Welders appreciate the consistency of Arcair products; the uniform diameter means you don't have to constantly adjust your travel speed or torch angle to maintain the groove profile. Whether you are in a shipyard, a structural steel shop, or a heavy equipment repair facility, these 3/8-inch carbons provide the aggressive metal removal rate you need to get the prep work done and start welding sooner.
