Product Features: - Fastest, most economical method of removing unwanted metal. - Uses a common arc welding machine. - Saves hours of grinding and machining time. –Properties: Length of Gouge per Second 1.0” & Weight of Gouged Metal per Min. 120g (using 310 amps) -- Current Type/Polarity: AC or DC straight polarity (Negative electrode) -- Recommended Amperage: Min 220 Max 330 -- Typical Applications: Cut and groove all metals including stainless steel, aluminum, cast iron, and copper. - Metal cutting / gouging / piercing / removal. - Removing bolts/plow bolts. - Sheet cutting and fabrication. - Dismantling welded structures such as towers, sign supports, and pipe piles. - Blowing out rivets. - Removing old weld overlays on railroad frogs, crossovers, and switches. - Preparing work hardened or heat treated dies for welding. -- Recommended Cutting / Gouging Techniques: No special equipment required. - Cutting can be performed Flat, Vertical Up, Vertical Down, Horizontal, or Overhead. - Use AC or DC straight polarity. - The electrode is pointed in the direction of travel, angled at a ten (10) degree angle, and the arc is initiated. - For a shallow chamfer, the electrode is moved quickly along line of cut. A slower or weaving motion provides a deeper groove. The molten metal is pushed ahead as the chamfer is made. - For cutting use a "sawing action". - For deeper grooves, the procedure is repeated until the desired depth is achieved. - Remove slag by chipping and brushing.
