* A stable and steady arc which is easy to strike and re-strike. * Easy slag removal and finely rippled smooth beads. * Weld metal of having lesser impurities i.e. S, P will improve the subzero impact property. * The electrode is used for welding similar composition materials and SA-182, F22V SA-336, F22V & SA-541, 22V. * Specially applicable wherever prolonged heat treatments cycles are involved. * Basically it is used for fabricating desulphurization reactors, heavy section pressure vessels having similar composition.
1. Ensure the electrodes are dry. Re-dry the electrodes at 250-300°C for one hour.
2. Use short arc, low current and stringer beads.
