N-12 / N-12A

Specification

Description

• N-12/N-12A is a high titania type electrode
• The resulting weld metal has a good bead appearance with shallow penetration
• Suitable for welding of steel sheets and general structures

 

Application

• Welding of cars, vehicles, machines and general light structural steel

 

Remarks

Pay attention not to exceed the range of recommended currents

Welding with excessive current not only lowers X-ray soundness but also causes increase of spatter, under-cut, and insufficient slag covering

For ultimate performance, dry the electrodes at 70-100 degrees C for 30-60 minutes before use

Excessive moisture absorption lowers usability and may result in porosity

Excessive drying before use may result in less penetration and overheating of the electrode
