Applications:
Welding of cars, vehicles, machines and general light structural steel.
Characteristics:
V-12 is a High Titania type electrode. Its weld metal has a good bead appearance with shallow penetration. It is suitable for welding of steel sheets and general structures.

Notes on Usage:
(1) Pay attention not to exceed the range of proper currents. Welding with excessive current not only lowers X-ray soundness, but also causes increase of spatter, under-cut and insufficient slag covering.
(2) Dry the electrodes at 70-100 degrees C for 30-60 minutes before use. Excessive moisture absorption lowers usability and may result in some porosities.
(3) Excessive drying before use causes less in penetration and overheating of the electrode.
