History发展历史 Mid 1940’s Myron Stepath conceived the idea while working as a Welding Engineer with US Navy in Bremerton, Washington 二十世纪四十年代中期，Myron Stepath在华盛顿州布雷默顿市在美国海军中担任焊接工程师时，开始产生碳弧气刨的初步构想。 Process combined carbon arc to melt and compressed air to blow it away 此工艺利用碳弧热量来熔化金属，同时用压缩空气将其吹走 Founded the company Arcair? in 1949 1949年Arcair?公司成立 CAC-A (Carbon-Arc Cutting – Air) CAC-A （碳弧空气切割） Uses an intense arc to create a molten pool on the work-piece 采用高能电弧在工件表面形成熔池 Compressed air is used to blow away the molten pool 采用压缩空气将熔池吹走 Requires a welding power source, air compressor, carbon electrode and gouging torch 要求具备焊接电源、压缩空气、碳棒及气刨钳 压缩空气 电源 直流或交流 电缆 工件线 气刨钳 碳棒 工件 * Slide * Maximum of 7” stick-out 碳棒最大伸出长度7” （177.8mm） Air jet should be on before striking the arc 起弧之前，应打开气阀开关 Air jet should be between the work surface carbon electrode 应该在工件表面和碳棒之间送气 Arc struck by bringing the electrode to work piece 将碳棒靠近工件，起弧 A short-arc should be maintained 35 – 56 volts 起弧电压应维持在35-56伏之间 Air Carbon-Arc Process (CAC-A) 碳弧气刨工艺（CAC-A） 伸出长度最大7‘’ 镀铜层剥开3/4’’至2‘’ 割枪 碳棒 枪头（+） 气压80psi(5.6kg/cm2) 持续位于碳棒之下 行进 工件(-) * Slide * Typical Applications典型应用 Weld Removal 焊接部位刨削（硬面堆焊） Back Gouging 清根 Edge Preparation 边缘准备（开坡口） Defect Removal 去除缺陷 Sever 切割 Removing Gates Risers 清除浇口
