Silvershine-308:
Lime-titania all position electrodes,exhibits smooth running with soft & stable arc with ease of striking and with negligible spatter.Self-peeling slag. Smooth bead appearance with fine ripples. Weldable on AC and DC+ polarity. Austenitic weld deposit which contains appropriate quantity of 'FERRITE' to prevent cracking. High degree of corrosion resistance in oxidising environments such as nitric acid.

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.
