ESAB OK Flux 80 - Fused - 20 X 200 - 55 lb Bag - 8244F21

OK Flux 80 is a neutral, fused flux for multipass welding of heavy plate. It is used primarily for the fabrication of pressure vessels, boilers, valves, and fittings. OK Flux 80 produces good weld metal properties when used with a wide variety of carbon and alloy steel wires. There is no limit to the thickness of plate that can be successfully welded with OK Flux 80. It is suitable for use with AC or DC power in single or multiwire applications. It is available in two mesh sizes. The 12x65 size is recommended for one and two wire welding at currents of up to 800 amps. The 20x200 size is suitable for use at up to 1100 amps and is recommended for multiwire and narrow groove welding. OK Flux 80 should only be used in applications where the base plate is free of rust and mill scale.
