Wipweld Cutting is conveniently used in piercing, gouging and cutting operations on difficult to machine metals and alloys, air and deep-hardening steels, hard overlay materials and metals which are difficult or impossible to cut with a torch; e.g., cast iron, stainless steels, armor plates. Especially recommended for field or on-site work. Successfully used in foundries to remove risers and gates on castings and to cut heavy scrap for re-melting.

Use DC straight (DC-) or AC current. Draw line where the cut is desired. Touch job with end of WIPWELDING Cutting rod and when the arc is struck, apply downward and upward motion holding the rod at and angle of 45 degrees. The downward motion should have a pushing effect to force out molten metal and slag while the upward motion should be fast. Maintain a short arc as you cut through the metal. On thick plates and heavy casting allow for puddling time and then proceed with a slow cutting motion. When cutting in vertical position, start at the bottom. Hole-punching – hold rod vertically, apply pressure and push through the metal. Hold will have the same diameter as that of the coated electrode. Gouging – hold electrode almost flat against the work similar to a chipping tool light pressure down and forward. Do not try to make the groove too deep on the first pass, only a depth of one half the diameter of the coated electrode, the forward motion must be fast enough to blow molten metal and slag ahead and out of the groove.
