Description and Applications: Description and Applications:
• High speed, high deposit (160% metal recovery), • Rutile electrode for fillet and horizontal V-welds
rutile electrode • 190% metal recovery with high speed welding
• Ideal for very fast fillet welding and for filling • Smooth weld appearance and self detaching slag
horizontal grooves Suitable for ship welding, pressure vessels,machines,
• Fully controlled molten pool, spatter free and self structures
detaching slag • Relatively high absorption energy at low temperature
• Suitable for welding on moderate and thick plates
for buildings, bridges, shipbuilding, etc
