Executive PLUS electrodes have a unique European formulation designed for the most discriminating operator.  Improved silica-titania (AC-DC) coating resists moisture pick up. A careful selection of raw materials and an advanced manufacturing process guarantees the electrodes resist starting porosity; even under extreme humidity and when left exposed to the atmosphere for prolonged periods. Noble chemistry improves corrosion resistance in challenging environments and actual weld deposit chemistries as well as controlled ferrites with each batch. 

Executive PLUS 309/309L provides superior weldability, low spatter and smooth beads with easy slag removal and can be used in all positions when welding as root runs in butt welds and thin plates in general.  Executive 309L deposits are not as strong at elevated temperature as the niobium-stabilized alloy or Executive 309H deposits. If postweld heat treatment of the carbon steel is essential, the total procedure, welding and heat treatment should be proven prior to implementation.
