Notes on usage:

  • Ensure that electrodes are dry enough. In case of moisture pick-up, redry the electrodes at 250°C for 30 to 60 minutes. Thereafter, either allow the oven to cool slowly to about 60°C or transfer them to a holding oven maintained at 50°C-60°C.
  • Clean the joint faces to remove moisture, grease or any foreign matter.
  • Employ welding currents within the prescribed range.
  • Keep the arc as short as possible.
  • Restrict weaving of electrode to within two and a half times the core wire diameter.
  • Use stainless steel wire brush for cleaning the weld beads.
  • These precautions become necessary for the very nature and fiedld of application of this electrode.
