Austarc 13S is the popular “blue and white striped” general purpose electrode for smooth mitre fillet welding applications. 13S has a soft and stable arc and produces flat, uniform fillet welds with ease and a self-peeling slag action. Austarc 13S is formulated primarily for fillet welding in all down hand positions. It is ideal for the general purpose and structural welding of sheet and plate steels (galvanised or otherwise) and tubular components, including trailers, duct work, hoppers and storage tanks, etc.
