电弧鋸在结构上及其使用上都和摩擦鋸有共同之处,但是热量來源不同。电弧鋸是利用电弧把热量传递到被切割工件上,使与鋸片接触处的工件熔化并以氧化铁及小铁珠形式拋入空间。电弧锯设备費用和维护费用低,而生产率高,对切割薄的截面形状材料如厚度在20公厘以下的鋼板、型钢及管子鋼筋等最为有效,对于其他各种导电材料,不論其硬度,韌性以及其他影响机械 The arc saw in the structure and its use and friction saw have something in common, but the heat from different sources. Arc saw is the use of electric arc to heat transfer to be cut on the workpiece, so that the workpiece contact with the blade melted and iron oxide and small iron beads into the space. Arc saw equipment costs and maintenance costs low, and high productivity, the cutting of thin cross-sectional shape of materials such as the thickness of 20 mm below the plate, steel and pipe reinforcement, etc. the most effective for a variety of other conductive materials, regardless of hardness, toughness And other effects of machinery
