The information contained or otherwise referenced herein is presented only as “typical” without guarantee or warranty, and Industrial Welding Corporation expressly disclaims any liability incurred from any reliance thereon. Typical data and test results for mechanical properties, deposit, or electrode composition and other properties were obtained from a weld produced and tested according to prescribed standards and should not be assumed to be the expected results in a particular application or weldment. Actual results will vary depending on many factors, including, but not limited to, weld procedure, plate chemistry and temperature, weldment design, and fabrication methods. Users are cautioned to confirm by qualification testing, or other appropriate means, the suitability of any welding consumable and procedure before use in the intended application.

  • Used on poorly weldable cast iron, such as burnt and bad castings and for bufferring the sides of the seam
  • Suited for wear resistant build up on solid castings
  • Bare the welding zone
  • With thick-walled workpieces, it is advisable to use NFG for grooving-out.
  • Select the lowest amperage as possible
  • With short arc guide the electrode steeply, buffer thin passes with NC-10
  • Weld the filling passes with NC-100 or NC-50
  • If the surface of the welded joint must be machinable, it is advisable to weld the cover passes with NC-100 or NC-50
