DC Rectangular Gouging Carbon Rods Copper Coated Flat Carbon Electrodes For Arc Air Gouging And Metal Cutting Description:
The DC Rectangular Gouging Carbon Rods are premium-quality copper-coated flat gouging rods specially designed for arc air gouging, weld removal, defect repair, and metal cutting applications. Manufactured from high-purity carbon materials with a uniform copper coating, these flat gouging carbon electrodes provide excellent electrical conductivity, stable arc performance, and efficient metal removal.
These DC copper-coated flat gouging rods are ideal for removing defective welds, preparing welding grooves, cutting metal sections, and cleaning casting defects. The rectangular design offers a wider gouging profile and higher metal removal rate compared to standard round carbon electrodes, improving productivity and operational efficiency.
The arc gouging carbon rods are suitable for use on carbon steel, stainless steel, alloy steel, cast iron, and other ferrous metals. They are widely used in shipbuilding, steel structure fabrication, pressure vessel manufacturing, heavy equipment repair, foundries, bridge construction, and industrial maintenance applications.
Featuring low consumption, smooth operation, strong arc stability, and excellent durability, these copper-coated gouging rods are the preferred choice for professional welders and industrial fabrication workshops requiring efficient metal removal and surface preparation.
