Silvershine-309Cb:

A medium heavy coated rutile type all position electrode giving 25/12 Columbium stabilised deposit. The weld deposit can with stand up to 1100°C temperature in continuous service. Excellent resistance to chemical corrosion and heat. Gives a smooth arc with least spatter and fine bead with easy slag detachibility

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
