Description : It is a cellulose coated electrode, it has 0.50 % Mo content. Excellent molten pool control due to easily-removable slag and gaseous arc shilling eliminates porosity problems in weld beads which have good mechanical properties. In all positions, preferable for vertical down position, it enables notch-free, smooth weld beads of high penetrations.  
Application : It is especially designed for the site welding of higher strength pipe and pipelines with 0.50 % Mo, that carries natural gas, crude petroleum or alike, for the welding of large diameter pipelines made of high resistant steels, It is particularly used on pipe steels in the 5LX52 – 5LX56 range. Ship building; storage tanks, and boiler steel constructions, root and fillet pass welding in all positions and pressure vessel manufacturing are among its vertical downwards position.
