所謂正常切割是指開始切割形成后的切割過程，基本的操作方法有支持切割法、維弧切割法、深度切割法3種。 所謂支承切斷法，是指在通過電弧起動形成開始切口后，狹縫傾斜而與切斷面保持80°~85°的角度，通過狹縫藥皮套筒支承在工件表面，在狹縫移動中，始終不離開工件的電弧氧切斷法。該方法從左到右，從右到左，均可在量規上切割，操作方便，效率高，適用于中、薄板水下切割。 所謂維電弧切割法，是在形成開始切割后，使切片條從工件表面離開約2~3mm，保持與工件垂直，然后，沿切片線均勻地向前方移動，維持電弧不消失，操作方法如圖5(b)所示。該方法適用于厚度5mm以下的薄鋼板的水中切割。潛水員在水中很難保持身體的穩定，所以電弧很難穩定。另外，切斷品質也比支持切斷法稍低，因此在實用上不怎么采用維電弧切斷法。 加深切割的方法是指，在開始切割形成后的切割過程中，繼續在狹縫中加入狹縫，加深狹縫，直到切下工件為止，這樣來回移動，總有 工件會切斷。此方法適用于支撐切割法中不易同時開裂的厚板和層壓板。操作時切片的上下移動，為了維持電弧的穩定燃燒，必須協調均勻。
