OK Flux 350


OK Flux 350 is an active bonded flux for making butt and fillet welds in carbon steel plate up to 1" (25 mm) thick. It produces a smooth weld surface with uniform edges. The slag is generally free peeling. Its performance is very good even when the plate surface is covered with rust and mill scale. OK Flux 350 is suitable for use with AC or DC power in single or multiwire applications. It is recommended for butt welding of thin wall pressure vessels, rail cars, and structural steel plate. It is used for fillet welding in shipbuilding, pressure vessel, and structural applications. OK Flux 350 also is widely used as a backing flux in one sided welding. It provides good performance at currents up to 1100 amps.
