摘要
NSA—200交直流氩弧焊机是一种新型的焊接电源。它具有焊接电流调节范围宽;焊接过程电孤稳定等特点。电源采用脉冲稳弧和方波焊接电流对于交流氩弧焊最小电流可稳定在5安,对于直流氩孤焊最小电流可稳定在4安。因此这种电源很适合于黑色及有色金属的薄壁结构件焊接。同时可作为交、直流的手工电弧焊电源。
The NSA-200 AC/DC TIG welding machine is a new type of power source of welding.It has characteristics such as a wide range of current regulation and stable are in the welding process.The smallest current can be stabilized at 5A for AC TIG or at 4A for DC TIG welding by using a pulse are stabilizer and the square wave welding current.Therefore,it is very suitable for welding the thin-wall construction of ferrous and nonferrous metals.It is also suitable for manual are welding of AC/DC power source.
