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.

  • Welding of cars, vehicles, machines and general light structural steel

 

  • Pay attention not to exceed the range of recommended currents
  • Welding with excessive current not only lowers X-ray soundness but also causes increase of spatter, under-cut, and insufficient slag covering
  • For ultimate performance, dry the electrodes at 70-100 degrees C for 30-60 minutes before use
  • Excessive moisture absorption lowers usability and may result in porosity
  • Excessive drying before use may result in less penetration and overheating of the electrode
  • For Philippine market only
