AFTEK-EHS Heavy Duty Air-Arc Gouging Power Supplies
Air arc gouging uses a generated electric arc to melt metal between the tip of a carbon electrode and the workpiece. High velocity air is shot down the electrode to blow the molten metal away, leaving a clean gouge. Gouging works on any conductive metal, including stainless steel, mild steel, copper, and aluminum. Typical applications include removal of surface and internal defects, removal of excess metal around welds, and edge preparation before welding.
