Suitable for fabrication and repair welding of dynamically loaded steel constructions, machines and agricultural equipments, workshop and maintenence welding. Smooth and clean welds, blending into base metal without undercuts. Excellent gap bridging properties. The double covering of this electrode produces a stable, concentrated and directed arc, thus being ideally suited for root pass and positional welding and is suited for AC welding. Welds are of X-ray quality.

Suitable for welding fabrication of dynamically loaded steel contructions, bridge, shipbuilding, pipe-line, pressure vessels, tanks, boiler and machines where high tougness is required. Weld metal recovery is appx. 115 %. Smooth and clean welds merging into base metal without undercuts. Good gap bridging properties. Welds are of X-ray quality. It is suited for depositing buffer layers on higher carbon steels.

Suitable for welding fabrication of dynamically loaded heavy steel constructions, bridge, shipbuilding, pipe line, pressure vessels, tanks, boiler and machines where mechanical properties are required. Weld metal exhibits good toughness properties down to -60°C and produce tough and crack-free welded joints even on steels having a carbon content of up to 0.4%. Weld metal recovery amounts to approx. 120%. Welds are of X-ray quality. Electrode is suitable for depositing buffer layers on higher carbon steels.
