Characteristics
A rutile coated general purpose electrode, the most popular in its class for economy and versatility. Good penetration and easy slag detachability. Easy to use and no special technique is required. It is suitable for all positional use and particularly for downhand and horizontal-vertical positions. Gives a sound joint even on rusty plates and uneven joints with higher root gaps.
Applications
General purpose welding of mild steel particularly grills, gates, repair jobs, steel furniture, steel frame work, truck and bus bodies, super structure of ships and all type of fabrication work.
