ESAB OK Flux 50 - Fused - 12 X 150 - 55 lb Bag - 8214F14

OK Flux 50 is a neutral, fused flux that performs well in a wide variety of applications. It is used for build up and hardsurfacing applications, and also for making butt and fillet welds in structural and pressure vessel steel plate. OK Flux 50 is suitable for use with AC or DC power in single or multiwire applications. It is available in two mesh sizes. The 8x48 size is recommended for build up and hardsurfacing applications at currents of up to 800 amps. The 12x150 size is suitable for use at up to 1100 amps and is recommended for all applications where the travel speed is less than 60 in/min (150 cm/min). OK Flux 50 is not recommended for use over rust or heavy mill scale
