    CG1-2A H Beam cutter 5. Neutral flame ensures good quality cut surfaces. (Oxygen flame may be used for bevel cutting.)Oxygen flame causes short cutting-oxygen current, allowing slugs to adhere, melting the upper edge of the cutting surface, and causing adverse effects on the cut surface. Similar defects will result when the cutting oxygen pressure is too high.
