OK 53.04 is an LMA electrode for welding in all positions, excellent on AC in the vertical position. It has very good running characteristics, gives a low amount of spatter loss and a thin slag, which is easy to remove. The electrode is also characterized by good arc stability at low amperage. For root runs in single V joints welding on DC- is recommended because of the cooler weld pool.
