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.
