N-11

Specification

Description

• N-11 is a cellulosic type electrode for mild steel designed for AC power use
• The strong arc force and rapid solidification of metal facilitate welding in the vertical and overhead positions
• The arc can be directed easily in any position with light slag formation and minimum spatter loss

Application

• Welding of pipes and general structures

Remarks

Pay attention not to exceed the range of the recommended welding currents because the proper currents for cellulose type electrodes are lower in comparison with those for ordinary type electrodes

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 lesser penetration and overheating of the electrode
