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.

  • For welding austenitic steel with the same analysis as the weld metal (AISI304 stainless steel, etc.) and can also be used for the welding of AISI 301 and AISI 302 stainless steel
  • Remove dirt, such as oil and dust from the groove
  • Pre-heat is not necessary
  • Keep the arc length as short as possible
  • Rebake the electrode at 200-250C for about one hour before use
