Arc-Air Gouging Copper Coated Carbon Electrode. gouging rod, gouging carbon The carbon electrode for carbon arc gas planning is an electrical Pole used in the carbon arc gas planning. The electrical arc can be produced between electrode and metal objects as electrical Pole and metal objects form electrical loop. The heat produced by electrical arc melt metal and compressed air blow away melt metal residues around the carbon electrode. The technology of using this method to cut metal or make slots on metal or remove redundant metal parts is called carbon arc gas planning.The carbon electrode is mainly used in steel, iron, brass, hard alloy, stainless steel and other metal to slot, planning welding lines, remove redundant metal parts, cutting, making holes, filling the welding line defects and so on. 3.2mm x 305mm, 4mm x 305mm.....................13mm x 305mm............... 4mm x 355mm, 5mm x 355mm.........................16mm x 355mm................ 13mm x 430mm, 16mm x 430mm........................19mm x 430mm................. 10mm x 510mm, 13mm x 510mm........................19mm x 510mm...............
